1.0 DESCRIPTION AND OPERATION OF CONTROLS - POWER SUPPLY AND PENDANT
1.1 Power Source Description
The Remote Pendent (Figure 1.1) provides controls necessary to develop, save and call up
welding programs. Programming is selectable position or time-based.
Each program can consist of a maximum of 100 levels. Any and all welding parameters may be
changed at each of the 100 levels. Downslope will occur following completion of the final level
time period.
While welding, the operator can immediately override the programmed parameters within preset
limits.
1.2 Pendant Controls (Figure 1.1)
1.2.1 LCD Display
A color LCD display is used to display information. When powered up,
approximately 12 seconds is required for the microprocessor to boot, and the display
will remain blank.
1.2.2 Cursor Up Switch
Moves cursor up display.
1.2.3 Cursor Down Switch
Moves cursor down display.
1.2.4 Enter Switch
Enters item highlighted by cursor.
1.2.5 Soft Keys (Four)
Used to select menu items. These items/functions change depending on operation
mode (i.e., setup, programming, operation).
1.2.6 Home Position Switch
Depressing this switch will cause the weld Head to rotate until it reaches a Home
position, at which point rotation will cease. (Home Position for the D-Head/T-Head is
one of 6 locations located 60° apart around the Guide Ring.) Active only when no
arc is present, this switch causes the Head to move forward until one of the position
notches on the guide ring is found. When using Autorewind, the weld Head will
rotate in reverse until finding the Home location.
1.2.7 Start Weld/Start Downslope
Used to start a weld, or to initiate downslope if a weld is in progress.
1.2.8 Emergency Stop Switch
Used to immediately terminate the weld cycle and all weld Head functions.
ATTENTION: In nonwelding operation, this switch is used as an “Escape” back
to the Start Up screen/Main Menu.

Function Switches
The following -/+ switches (1.2.9 thru 1.2.19) perform multiple functions depending on the operating
conditions.
•During programming, these serve to directly input the desired parameter values.
•During “Run Program” mode, these serve as JOG switches, when no arc is present.
•During welding, they serve as override switches for each function, within the preset limits of
the % override screen.
1.2.9 Current Switches
Used to decrease/increase welding current level in both programming and welding
modes.
1.2.10 Travel Switches
Used to decrease/increase welding travel (rotation) speed in both programming and
welding modes.
1.2.11 Wire Switches
Used to decrease/increase welding wire speed in both programming and welding
modes.

4
1.2.12 Arc Length Switches
Used to decrease/increase welding arc length (and therefore arc voltage) in both
programming and welding modes.
1.2.13 Oscillation Speed Switches
Used to decrease/increase welding oscillation speed in both programming and
welding modes.
1.2.14 Oscillation Amplitude Switches
Used to decrease/increase oscillation amplitude (torch weave width) during both
programming and welding modes.
1.2.15 AGC Stop Switch
This switch and the Wire Stop are used primarily in weld repairs. Depressing this
switch causes the AGC operation to cease. While the AGC is disabled, a warning
indicator is displayed on the LCD. Depressing the switch a second time causes the
function to once again become active.
When the AGC Stop switch is on, the two AGC Switches can be used to jog the
torch up/down.
1.2.16 Wire Stop Switch
Operation of this switch is similar to that previously described, except that the
function interrupted is wire feed.
When the WIRE STOP switch is depressed, filler wire feed will be interrupted until
the switch is again depressed. A warning indicator is displayed. When the WIRE
STOP switch is actuated, the two wire switches can be used to jog wire.
1.2.17 Rotary Encoder
This multifunction control can be used to increase/decrease any parameter that has
been selected during programming. During welding, this is used to “steer” the torch
in the seam, and adjust the center point of the oscillation strokes.
1.2.18 Inner & Outer Oscillation Dwell
During programmed and welding modes, the four soft keys adjust the inner and outer
dwell times. Oscillation dwell is the time period that the torch remains stationary at
either stroke end points. (“Inner” refers to the location where the Torch is closer to
the weld Head body, “Outer” the reverse.)
1.2.19 USB Port (At Top of Pendent)
A standard digital “data key” connects to the USB port. This allows program transfer
between power sources, program archiving, and QC data downloading. Weld
parameters can be downloaded for subsequent print out on a PC equipped with a
printer.
1.3 Front Panel Controls
1.3.1 Emergency Stop Switch
Used to immediately terminate the weld cycle and all weld Head functions. Will also
“reboot” the system.

5
1.4 Rear Panel (Figure 1.4)
All connections are made on the Rear Panel.
Figure 1.4 - Rear Panel
1.4.1 Water Circulator Connector
A connector is provided to power the Water Circulator and to provide to provide
Water Flow Switch protection. (A Water Flow Switch is mounted in the Water
Circulator.)
The water flow switch is factory calibrated. Interruption in water flow will result in
termination of welding and a warning message on the display.
1.4.2 Gas Flow Switch
The Pipemaster Power Source is equipped with a Gas Flow Switch that is factory
preset. Shielding gas must be flowing to the weld Head in order to be able to initiate
a welding arc. If gas flow to the weld Head is insufficient, depressing the START
WELD switch will not initiate a welding arc. If the gas flow is interrupted during
welding, the flow switch will immediately cause the arc to be extinguished. If gas
flow is interrupted, a warning message will be displayed.

3.2 Obligations Of Owner/Operator
The owner operator undertakes to ensure that the only people allowed to work with the power
supply:
•Are familiar with the basic regulations on workplace safety and accident prevention and who
have been instructed in how to operate the equipment.
•Have read and understood the sections on safety and the warnings contained in this manual
•Keep a copy of the instruction manual at the welding location at all times
Welding products and welding processes can cause serious injury or death, and possibly can
cause serious injury or death, and possible damage to other equipment if the operator does not
strictly observe all safety rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These
practices must be learned through study and training before using this equipment. Anyone not
having extensive training in welding practices should not attempt to weld.
Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN
WELDING AND CUTTING. This publication and other guides to what you should learn before
operating this equipment are listed later in this section.
3.3 Shock Prevention
Bare conductors, or terminals in the output circuit, or ungrounded, electrically live equipment
can fatally shock a person. To protect against shock, have a competent electrician verify that
the equipment is adequately grounded, do not make contact with terminals and parts that are
electrically HOT.
The body’s electrical resistance is decreased when wet, permitting dangerous currents to flow
through the body. Do not work in damp area without being extremely careful. Stand on dry
rubber mats or dry wood and use insulating gloves when dampness or sweat cannot be
avoided. Keep clothing dry.
3.3.1 Installation and Grounding of Electrically Powered Equipment
Electrical equipment must be installed and maintained in accordance with the
National Electrical Code, NFPA 70, and local codes. A power disconnect switch must
be located at the equipment. Check equipment nameplates for voltage and phase
requirements. DO NOT CONNECT the equipment-grounding conductor (lead) to the
third live wire of the 3-phase line as this makes the equipment frame electrically HOT,
which can cause fatal shock.
If a grounding lead (conductor) is part of the input power cable, be sure to connect it
to a properly grounded switch box or building ground. If not part of the supply cable,
use a separate grounding lead (conductor). Do not remove a ground prong from any
plug. Use correct mating receptacles. Check ground for electrical continuity before
using equipment.
3.3.2 Torch and Work Cables
Inspect cables often for damage to insulation. Replace or repair cracked or worn
cables immediately. Do not use a welding current in excess of rated cable capacity,
as the cable will overheat.

13
3.3.3 Power Source Output Terminals
The Power Source completely shields the output terminals when the Torch and Work
Cables are connected.
3.3.4 Service and Maintenance
Shut OFF all power at the disconnect switch or line breaker before inspecting or
servicing the equipment. Unplug the input power cord. If the equipment is wired
directly to an electrical box, lock the switch OFF (or remove line fuses) so that power
cannot be turned ON accidentally. Disconnect power to equipment if it is to be left
unattended or out of service.
3.3.5 Fuse and circuit Breakers
Replace fuses and circuit breakers with equivalent sizes.
3.4 Burn Prevention
The welding arc emits high-energy radiation in the infrared and ultraviolet range. This energy
penetrates lightweight clothing and is reflected from light-colored surfaces. The arc rays can
injure the eyes permanently and burn the skin, just as in “sunburn”. Never look at an electric arc
without eye protection.
3.4.1 Protective Clothing
Wear gloves, suitable long sleeved shirts/jackets, safety shoes, welding helmet, and
other articles needed to shield the skin and to prevent injury from arc burns. Wear
earplugs if welding overhead or in a confined space. Wear a hard hat if others are
working above you.
3.4.2 Eye and Head Protection
Protect your eyes and Head by wearing a welding helmet fitted with a double lens;
use a clear lens outside and a colored, welding filter inside. Use a filter suitable for
the amperage level being used for a specific task.
Always lower the helmet before striking the arc. Wear safety glasses with side
shields under the helmet to protect the eyes from flying particles and side arc flashes
when the helmet is up.
Protect the eyes of other people in the area by use of opaque, non-reflecting and
nonflammable screens around your welding station. Allow good air circulation,
especially at floor level. Do not permit anyone to view the arc unless he uses a
correct hand shield, or helmet.
3.4.3 Hazards from Flying Sparks
Move all combustible objects well away from the welding location. Welding must
NEVER be performed on containers that have had gases, fuels, mineral oils etc.
stored in them. Even small traces of these substances left in the containers are a
major explosion hazard.

14
3.5 Toxic Fume Prevention
Breathing the fumes created during welding or cutting can cause illness or death. If adequate
ventilation is not provided. Provided ventilation in accordance with ANSI Standard Z49.1.
Some fume sources are:
3.5.1 Weldments
Metals containing lead, cadmium, zinc, mercury and beryllium can produce harmful
toxic fumes when welded or cut. Adequate local exhaust ventilation must be used for
the operator and persons in the area.
3.5.2 Coated Weldments
Remove coatings that emit toxic fumes when heated or use exhaust ventilation and/or
an air supplied respirator.
3.5.3 Vessels That Have Contained Toxic Materials
The ultraviolet radiant energy of the arc can also decompose chlorinated solvents
such as trichloroethylene and perchloroethylene vapors to form the highly toxic gas -
PHOSGENE. Do not weld or cut unless such containers have been thoroughly
cleaned following AWS Standard A6.0. Keep all solvents well away from the arc
radiation.
3.5.4 Welding Area
Do not weld in locations close to chlorinated vapors coming from degreasing, cleaning
or spraying operations. The heat and rays from the arc react with the vapors to form
highly toxic PHOSGENE. Work in a confined space only if it is being adequately
ventilated, and if ventilation is not adequate, wear an air-supplied respirator (see ANSI
2.37).
3.6 Compressed Gas Cylinder Handling
Follow precautions below and those outlined in CGA Standard P-1, Precautions for Safe
Handling of Compressed Gases in Cylinders.
3.6.1 Cylinders
Handle carefully to prevent damage. Keep away from welding cables or other
electrical circuits. Use only cylinders with name of gas marked on them; DO NOT rely
on color identification. Close valves on empties and return promptly. Secure
cylinders so they cannot be knocked over. Keep temperature below 130 degrees F.
3.6.2 Pressure Regulators
Use the correct regulator for the gas and cylinder being used. Remove any
suspected faulty regulator and return to manufacturer's service center for repair.
3.7 Equipment Warning Labels
Inspect all precautionary labels on the equipment.
3.8 Alterations To The Power Supply
Do not make alterations or modifications to the power supply without first getting permission
from the manufacturer.
Immediately replace any components that are not in perfect condition.

15
3.9 Spares And Expendable Parts
Use only original spares and expendable parts. With parts purchased from other suppliers,
there is no certainty that these parts have been designed and manufactured to cope with the
operation and safety requirements that will be made of them.
When ordering spare parts, please give the exact description and the relevant part number, as
given in the spare parts list. Please also give the serial number of your machine.
3.10 Particular Danger Spots
Never hoist the power supply and cart with the gas cylinder bottle installed.
3.11 Calibration Of Power Supply
In view of international standards, regular calibration is advisable. Magnatech recommends a
12-month calibration interval. For more information, please contact Magnatech.
3.12 Safety Precautions At The Installation Location
The power supply must be placed on an even, firm surface so that it is stable and cannot fall
over. Special regulations apply to areas at risk from fire and/or explosion. Observe all relevant
national and international regulations. Ensure that the workplace and the area around it are
always kept clean and tidy.
3.13 Safety Precautions In Normal Operation
Only operate the power supply if all its protective features are fully functional. Before switching
power on to the power supply ensures that nobody can be injured. At least once a week, check
the power supply for any damage that may be visible from the outside, and check that the safety
features all function correctly.
3.14 Turn Power Off Before Connecting/Disconnecting Cables
Turn the Main Power Switch off before connecting or disconnecting any cables at the rear of the
power source to prevent possible damage to the electrical circuitry.
3.15 Safety Inspection
The owner/operator is obliged to have the power supply checked for proper condition by a
trained electrician after any alterations, installations of additional components, modification,
repairs, care and maintenance, and in any case at least every twelve months.
In the course of such inspection, the following regulations must be observed (as a minimum):
•IEC (EN) 60 974-1 – Arc welding equipment – Part 1: Welding power sources
•VBG 4, 5 – Electrical plant and apparatus
•VBG 15, 33/49 – Welding, cutting and allied processes
