“KAT”®CARRIAGE/COMPACT OSCILLATOR COMBINATION
This manual covers the operation instructions of the following “KAT”®Carriage/Compact Oscillator
systems, all position, variable speed travel carriages and either Linear or Radial Oscillator heads (*
indicates input voltage: ‘A’ = 42 VAC; ‘B’ = 115 VAC; ‘C’ = 230 VAC):
GK-L-300-* / GK-R-300-*
GENERAL DESCRIPTION
This advanced Gullco oscillation package combines the Gullco “KAT”®all position, travel carriage
with either the Linear or Radial compact oscillator head and oscillator control which is incorporated
into the carriage.
The Gullco “KAT”®is a heavy duty, all position travel carriage. It is an electrically powered, self
propelled carriage that travels in a forward or reverse direction, at precisely controlled speeds, along
a special track. The self aligning wheel system of the carriage grips the top and bottom of the track,
enabling it to travel along any plane. The bogey wheel assembly keeps the carriage snug to the
track, while allowing it to be easily mounted and removed from the track at any point. The positive
drive of the “KAT”®is obtained from a pinion that engages with the rack of the rigid track. This system
is driven by a low voltage permanent magnet motor and gear-head power unit assembly. Safety is
greatly enhanced by the use of Gullco’s low voltage (24 V), highly advanced control/power supply
system that is available in three line voltage inputs... 42, 115 and 230 VAC, single phase, 50/60 Hz,
or any unregulated 24 VDC power supply at 150 watts of power. The micro-processor carriage motor

4
control offers operator interface of forward, stop, reverse and infinitely variable control of the speed,
within the range of the model, as well as an L.E.D. display indicating speed in either in/min. or cm/min.
The Gullco Linear and Radial oscillator heads are compact, light weight, yet durable, reciprocating
devices with high torque, high resolution and low vibration stepper motors. They impart a linear,
pendulum or tangential motion to the welding gun. The low voltage Oscillator Control provides a
large, easy to read, multi-page graphical display and offers programmable and electronic adjustment
over the following functions:
•Oscillation width
•Oscillation speed
•Independent Left, centre and right dwells
•Oscillation centre positioning (steering)
•Automatic wire feed activation
•Automatic and Manual carriage travel activation
•Weld travel start delay and weld crater fill delay
•Standard (angular) or step (square) pattern oscillation
•Multiple oscillation program storage
These features enable precise control over the automated cycle generating accurate and repetitive
weld oscillation.
Adjustable bracketry as well as vertical and horizontal Micro Fine Adjustable Rack Boxes, allow the
welding gun and the oscillator head to be easily mounted, adjusted and accurately positioned, in
virtually any plane, off the front or back of the “KAT”®carriage.
INTENDED / FORESEEN USAGE
The Gullco “KAT”®Carriage/Compact Oscillator combination is used throughout the world to
automate and improve the quality and efficiency of the weld produced in automatic mechanized
welding operations. This is achieved through minimizing weld defects such as poor penetration,
incomplete fusion, overlap and undercut. Also, detrimental factors such as poor or awkward
accessibility, operator fatigue, or inconsistent workmanship are eliminated. Required quality levels
are consistently attained and productivity and profitability increased.
Welding guns are readily mounted on the oscillator head and either a linear, pendulum or tangential
motion is used to produce either a standard angular or step (square) weld pattern. The track that the
“KAT”®carriage is going to travel along, is positioned so that the “KAT”®will move the oscillator head
and welding gun along the desired path and then securely held in place using magnetic or vacuum
activated mounting devices. Safety back-up devices such as chains at the ends of the track; or
welding some track mounting devices to the work-piece; must be implemented whenever there is a
possibility that the equipment may fall due to gravity. By combining welding gun oscillation movement
with the precision controlled travel speed of the “KAT”®carriage, a wide range of weld patterns can
be produced....as described on the following pages.

OPERATION
The electrical and mechanical installation of the “KAT”®Carriage/Compact Oscillator system is
explained in the Technical Manual (GD-087-T).
Local Control Devices
The Power On/Off switch is used to disconnect the power to the rest of the control circuitry.
I = On, O = Off.
WARNING! Always turn the main power off before connecting/disconnecting the oscillator head
cable to/from the “KAT”®carriage.Failure to comply may result in control damage.
Oscillator Head Connector
Arc Activation Signal Connector
(Trigger Signal)
Oscillator Control
Carriage Motor Control

WARNING! The motor and oscillator controls must not be continually started and stopped by the
removal and reapplying of power to the controls. Turning the power off to the controls
will not provide instant braking and continued use will damage the controls. Allow ten
(10) seconds after the removal of power before reapplying the power to the equipment.
The Fuse Holder allows accessibility to the main fuse by pushing the cap in towards the main body
and twisting in a counter-clockwise direction.
The Arc Activation Signal Connector is used to interface with the trigger signal of the customers
welding equipment and is used to start/stop the welding process.
Either the Linear or Radial model of compact oscillator head can be plugged into the Oscillator Head
Connector (control needs to be calibrated to suite the type of head).
"KAT"®CONTROL (GSP-2100)
The L.E.D. Display
The control has an L.E.D. display that indicates the travel speed in either inches per minute or
centimetres per minute. The display also shows the travel direction accessed as well as the status
of the Stop command.
The Forward and Reverse L.E.D.’s indicate the “KAT”®carriage motor direction
commanded.
The “Hold” (stop) L.E.D. will illuminate whenever there is a “Hold” (stop) command
present. This could be any combination of either the “KAT”®Control Run/Stop switch
or the Oscillator Control Auto/Stop/Run switch being in the Stop position.

Externally, the Gullco “KAT”®Control has switching for Forward/Neutral/Reverse & Run/Stop, as well
as a rotary encoder for speed control.
= “STOP” - This over-rides all other controls and when activated will apply regenerative
breaking to the carriage motor to bring it to a dead stop, and will disallow any further
operation of the carriage while ever it is in this state. This position will also reset an
error code once the fault has been rectified. The Oscillator Control will also access
this command when it is in the “STOP” mode.
= “RUN” - This removes the “STOP” command and allows the control to assume an
operational status, allowing carriage motion when permitted by the oscillator control.
This command will be ignored if the Oscillator Control is in the “STOP” mode.
= “FORWARD” - When the switch is in this position, Forward motion is selected as the
desired “KAT”®carriage travel direction.
= “NEUTRAL” - When the switch is in this position, the control will not drive the “KAT”®
carriage motor in either direction.
= “REVERSE” - When the switch is in this position, Reverse motion is selected as the
desired “KAT”®carriage travel direction.
= “SPEED ADJUSTMENT” - By turning the multi turn rotary encoder knob in a
clockwise direction, the carriage motor speed will be increased. When rotated in the
counter-clockwise direction, the carriage motor speed will decrease. The speed of the
carriage travel can be preset, prior to any motion, by placing the
Forward/Neutral/Reverse switch of the “KAT”®control to “Neutral”. Then by turning
the variable Speed Adjustment knob, the travel speed can be set to the required value,
as indicated in the L.E.D. display.

OSCILLATOR CONTROL
A highly sophisticated, yet easy to use, multi-processor based
control drives a high torque, high resolution, low vibration
stepper motor located in the Oscillator Head, allowing the
welding gun to be moved in a precise reciprocative manner.
The control interfaces with the “KAT”®carriage travel and the
trigger signal of the welding equipment. By controlling the
oscillation width, speed, positioning and dwell patterns as well
as the timed activation/deactivation of the “KAT”®carriage
travel and the welding process, the quality and appearance of
the weld can be tuned to perfection.
The A, B & C rotary switches will increase
(clockwise adjustment) or decrease (counter-
clockwise adjustment) the A, B & C location
dwells respectively by 0.1 second increments,
from a minimum of zero up to a maximum of
9.9 seconds. The current values are displayed
on the LCD screen. These adjustments can be
changed at any time before, or during,
operation and will take effect on the next
relevant dwell location. The orientation of the
ABC locations of the Oscillator Head can be
altered (programmed) to match the orientation
of the control (see the Technical Manual, GD-
087-T for details).
The Dwell Enable/Disable switch will allow the
oscillator to perform the A, B & C location dwell
timing cycles while running when Enabled (
) or will not perform the dwells when
Disabled ( ). This Enable/Disable selection
can be made at any time and will take effect
immediately. When disabled the LCD screen
will show all dwell times as zero and the dwell
disabled icons crossed-out, as shown
adjacent:
The W rotary switch increases (clockwise
adjustment) or decreases (counter-clockwise
adjustment) the total width of the oscillation stroke
(A to C). The increments of adjustment and the
minimum and maximum allowable stroke widths
are dependent on the type of Oscillator Head
used and the preferred units of measurement (see
the Technical Manual, GD-087-T for details). The current value is displayed on the
LCD screen. Width adjustments can be changed at any time before or during
operation and will take effect on the next travel past the B location. Note:- there is a
width range where the oscillation stroke is too small to permit A, B & C dwells to work.

minimum and maximum allowable stroke speeds are dependent on the type of
Oscillator Head used and the preferred units of measurement (see the Technical
Manual, GD-087-T for details). The current value is displayed on the LCD screen.
Speed adjustments can be changed at any time before or during operation and will
take effect immediately.
The Center Position Adjustment rotary switch will allow the operator to jog the center
position (B location) either to the left or to the right. This rotary switch can be used to
position the welding gun prior to oscillation when the Manual/Hold/Auto switch is in the
Manual position. To make adjustments (steering) while welding, rotate the Center
Position Adjustment rotary switch in the appropriate direction until the centre of the
oscillation has moved to the desired location. The size of these centre adjustment
(steering) increments can be programmed to be as large or small as preferred (see
the Technical Manual, GD-087-T for details).
The Arc Enable/Disable switch will allow the operator to either Enable ( ) or Disable
( ) the arc activation signal to the welding equipment. This Enable/Disable selection
can be made at any time and will take effect immediately.
When Enabled ( ), the arc activation signal will be energized while-ever the
oscillator is running. When the arc activation signal is energized, the arc activation
signal icon in the lower left corner of the LCD screen will appear as follows:
When Disabled ( ), the arc activation signal will de-energize (if applicable) and
remain de-energized.While ever the arc activation signal is de-energized, the arc
activation signal icon in the lower left corner of the LCD screen will appear as
follows:
The Manual/Hold/Auto switch is used to start and stop the oscillator equipment as well
as interfacing with the “KAT”®travel carriage.
In the Manual position ( ), the arc activation signal and the oscillator head are
inactive, and the “KAT”®carriage will operate manually. The carriage release icon
on the lower right corner of the LCD screen will appear as follows:
The Hold position ( ), over-rides all other controls and when activated will apply
the Hold (stop) signal to the “KAT”®carriage control, and will disallow any further
operation of the “KAT”®while ever it is in this state. The arc activation signal and
the Oscillator Head remain inactive in this mode. The carriage hold icon on the
lower right corner of the LCD screen will appear as follows:
When placed in the Auto cycle position ( ), the arc activation signal will
energize (only if the Arc Enable/Disable switch is in the Enable state) and the
Oscillator Head will start its oscillation motion. After the programmable Travel Start
time delay the oscillator control will deactivate its Hold (stop) command to the
“KAT”®carriage control, thus allowing it to travel. While ever the Hold (stop)

10
command is released to the “KAT”®carriage, the carriage release icon on the lower
right corner of the LCD screen will appear as follows:
The Program push button changes the control state from running (operational) mode
to programming mode, and back to running mode. While-ever the control is in
programming mode, the program icon on the lower right corner of the LCD screen will
appear as follows:
AUTOMATIC CYCLE OPERATION
To perform an automatic welding cycle:
1. Place the Oscillator control Manual/Hold/Auto switch in the Hold position.
2. Place the “KAT”®carriage control Run/Stop switch in the Run position.
3. Set the “KAT”®carriage travel speed by placing the “KAT”®carriage control
Forward/Neutral/Reverse switch in the Neutral position then rotate the Speed Adjustment
knob until the desired speed is displayed.
4. Place the “KAT”®carriage control Forward/Neutral/Reverse switch to the desired weld travel
direction.
5. Using the devices on the Oscillator control, set the desired oscillation width, oscillation speed
and dwells.
6. When the Oscillator control Manual/Hold/Auto switch is placed in the Auto position, the
programmable audible warning buzzer duration elapses while the optional buzzer is energized
(if the optional buzzer is not installed this timing cycle is usually programmed off). Then the
oscillation motion will commence and the arc activation signal will be energized (if the Arc
Enable/Disable switch is in the Enable position). Following the Travel Motion Delay, the Hold
(stop) signal to the “KAT”®carriage control is released and the carriage starts its weld travel.
7. When the Oscillator control Manual/Hold/Auto switch is placed in the Hold position, the Hold
(stop) signal to the “KAT”®carriage control is energized again, stopping the “KAT”®carriage
travel, and the Oscillator Head motion is stopped. After a programmable Crater Fill Delay the
arc activation signal is de-energized and the automatic cycle is completed.
The following are some notes on the operation of the control.
1. When the oscillation is to start, the Oscillator control will always assume that the oscillator
head/slide is resting at the “Oscillation Rest Location” (4th Field of the Features & Setup
screen, described later in this manual) and will travel in the appropriate direction accordingly.
I.e. if the “Oscillation Rest Location” field is set to C, the oscillator will start its oscillation cycle
by moving in the relevant direction toward the B (center) location by a distance of half the
width value (W).

11
PROGRAMMING
There are two levels of programming mode:
General Programming Mode: this first level of programmable features is meant to be easily
accessible to the operator and requires that the Program push button ( ) be pressed
for a minimum of two (2) seconds, but no more than ten (10) seconds, while the
Manual/Hold/Auto switch is either in the Manual or Hold position. The screens that are
accessible under this mode are:
oFeature/Set-up screen and;
o10 x Auto cycle storage screens.
Advanced Programming Mode: this second level of programmable features is meant only
tobe used by higherlevel and/or qualified usersandrequires that theProgrampush button
( ) be pressed for more than ten (10) seconds while the Manual/Hold/Auto switch is
either in the Manual or Hold position. The screen that is accessible under this mode is:
oMotor Setup screen (see the Technical Manual, GD-087-T for details)
To change state from programming mode (any screen) to running (operational) mode, press the
Program push button ( ) once (it does not need to be pressed for any specific duration). The
various values and settings will be saved.
When in the programming mode, only the A, B & C rotary switches and the Program push button will
be used. All other toggle and rotary switches will be ignored.
The A rotary switch is used to navigate forward and backward between screens (pages).
The B rotary switch is used to navigate forward and backward between adjustable fields of
the current screen (page). The contents of the selected field will flash to indicate which field
is currently selected.
The C rotary switch is used to change the value/setting of the currently selected adjustable
field.
The Program push button ( ) is used to save all values and settings, exit programming
mode and return to the running (operational) mode.
Note: If the Manual/Hold/Auto switch is placed in the Auto position when the control is in the
programming mode, the arc signal relay will not energize, the oscillator will not start to run and the
carriage Hold (stop) signal will not be de-energized. If the switch remains in the Auto position when
the control returns to the running (operational) mode, the system will remain display “ER.1”, requiring
the switch to be placed in the Hold position to reset.
While-ever the control is in programming mode, the program icon is displayed in the lower right hand
corner of the LCD screen as follows:

12
The sequence of level 1 (General Programming Mode) program screen displays is as follows:
Rotate the Arotary switch
clockwise to move forward
through the screens.
Rotate the Arotary switch
counter-clockwise to move
backwards through the
screens.

13
The Features & Setup Screen
The Features & Setup Screen has the following features:
1st Field = The Auto Cycle storage number to be recalled. The number shown in this field will be
the program that will be copied from storage and applied to the running (operational)
mode values when exited from programming mode. The choices are 0, 1, 2, 3, 4, 5, 6,
7, 8, 9, or 10 (surrounded by the auto cycle symbol). When the value is 0, the existing
oscillation values last used will not be over-written. Each time the Features and Setup
screen is opened, the value in this field defaults to 0.
2nd Field = The Oscillation mode. There are three pictorial modes to choose from:
Normal Oscillation. This is where the travel carriage is allowed to
run continuously through the oscillation cycles. This is the factory
default setting.
Step during Dwells. This is where the travel carriage is only
allowed to run during each of the A, B or C location dwells. This
mode will only work effectively if the dwell times are not too small.
Step during Oscillation stroke. This is where the travel carriage is
only allowed to run during each oscillation stroke (i.e. carriage is
not permitted to run during each of the A, B or C location dwells).
This mode will only work effectively if the dwell times and the
oscillation width are not too small.
3rd Field = Travel Motion Delay. This sets a timing delay at the start of an automatic cycle, from
the time that the arc activation signal is energized until the time that the travel carriage

Hold (stop) signal is de-energized. I.e. a timing cycle to allow the arc to strike and
establish, before carriage motion. The choices available are from 0.0 to 9.9 seconds in
0.1 second increments. The factory default setting is 0.3 seconds.
4th Field = Crater Fill Delay. This sets a timing delay at the end of an automatic cycle, from the
time that the travel carriage Hold (stop) signal is re-energized and the oscillation motion
stops until the arc activation signal is de-energized. I.e. a timing cycle to allow the
welding to continue after the welding motion ceases. The choices available are from
0.0 to 9.9 seconds in 0.1 second increments. The factory default setting is 0.5 seconds.
5th Field = Oscillation Rest Location. This setting dictates where the oscillator stops at the end of
an oscillation cycle (and therefore assumed location at the start of an oscillation cycle).
The choices are A, B or C. The factory default setting is B.
6th Field = Audible Warning Buzzer Duration. This sets the timing cycle for the optional audible
warning prior to the start of each Auto cycle. The choices are from 0 to 9 seconds in 1
second increments.
When the value is greater than 0, the following icon is displayed:
When the value is 0, the following icon is displayed:
Notes: All fields except the 1st Field retain the last value entered.

15
Auto Cycle Storage Screens
There are a total of ten (10) Auto Cycle Storage Screens, and each screen is identified by the “Auto
Cycle Storage Number” (numbered 1 to 10) as shown in the following image. The units of measure
for the oscillation width (W) and the oscillation speed (S) are programmable (level 2 - Advanced
Programming Mode). If the units of measure change, all width and speed fields will need to be
manually converted. To make changes to these screens/fields use the A, B & C rotary switches as
described on page 11. All the Auto Cycle Storage Screens have the following features:
1st Field = The A Location Dwell Time. This sets the time duration that the oscillation stroke will
dwell (pause) each time the A location is reached. The choices available are from 0.0
to 9.9 seconds in 0.1 second increments.
2nd Field = The B Location Dwell Time. This sets the time duration that the oscillation stroke will
dwell (pause) each time the B (center) location is reached. The choices available are
from 0.0 to 9.9 seconds in 0.1 second increments.
3rd Field = The C Location Dwell Time. This sets the time duration that the oscillation stroke will
dwell (pause) each time the C location is reached. The choices available are from 0.0
to 9.9 seconds in 0.1 second increments.
4th Field = The Oscillation Width. The value of this field sets the total width of the oscillation stroke
(A to C). The increments of adjustment and the minimum and maximum allowable
stroke widths are dependent on the type of Oscillator Head used and the preferred units
of measurement (see the Technical Manual, GD-087-T for details). Note:- there is a
width range where the oscillation stroke is too small to permit A, B & C dwells to work.
5th Field = The Oscillation Speed. The value of this field sets the oscillation stroke speed. The
increments of adjustment and the minimum and maximum allowable stroke speeds are
dependent on the type of Oscillator Head used and the preferred units of measurement
(see the Technical Manual, GD-087-T for details).

ERROR CODES
Error codes are displayed on the LCD screen as shown adjacent.
ER.1
If the Oscillator Controls’ Manual/Hold/Auto switch is in the
Auto position on power-up, the control will display ER.1 and
not permit an automatic cycle to start. This prevents the
undesirable start of an automatic cycle on power-up. To reset
the error, place the switch in the Hold position.
ER.2
When the Oscillator Control is programmed to operate a Linear Oscillator Head (preferred units
of measurement are either Inches or CM), the control monitors limit switches located within the
Oscillator Head to prevent over-travel. If either, or both, of these limit switches are open circuit,
the control will display ER.2 and not permit normal operation. This situation could include the
following possibilities:
•Manually jogging the slide too far. To reset, manually jog the slide in the opposite
direction.
•The over-travel occurred during Oscillation.This could be due; to the oscillation width
being set too large for the stroke of the slide; the starting location of the oscillator slide
relative to the oscillation width and direction; or through making center position
adjustments (steering), resulting in slide over-travel. To reset, make the necessary
manual and/or programming adjustments and restart the automatic cycle. It is
recommended that the oscillator be set so that the oscillation occurs in the centre of
the slides stroke to permit center position adjustments (steering) without activating the
over-travel limit switches.
•Powering up the “KAT”®Carriage/Compact Oscillator without having a Linear Head
connected. To reset, either power down and attach a Linear Oscillator Head or
connect a Radial Oscillator Head and reprogram the Oscillator Control accordingly.
oWARNING! Always turn the main power off before connecting/disconnecting
the oscillator head cable to/from the “KAT”®carriage.Failure to comply may result
in control damage.
OPTIONAL ACCESSORIES
GK- 201-121 Optional Audible Buzzer Kit – Includes audible buzzer and wiring harness to
interface with the Oscillator Control, providing a programmable duration for the audible
warning buzzer to activate before starting an automatic cycle.
ER.4The control display has encountered a problem.
ER.5The control keypad has encountered a problem.
ER.6Stepper driver board over temperature: the temperature of the driver on the stepper board
has exceeded 96°C of 205°F. The control must be powered down and allowed to cool in
order to reset this code.
