DO NOT OPERATE TOOL UNTIL YOU HAVE READ
THOROUGHLY, AND UNDERSTAND COM-
PLETELY, ALL INSTRUCTIONS, RULES, ETC. ON
THIS PAGE, AND IN THE OPERATING MANUAL.
WHEN USING ELECTRIC TOOLS, BASIC SAFETY
PRECAUTIONS SHOULD ALWAYS BE FOLLOWED
TO REDUCE RISK OF FIRE, ELECTRIC SHOCK,
AND PERSONAL INJURY, INCLUDING THE FOL-
LOWING:
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk
of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching outlet that is
properly installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided – if it will not fit the outlet, have
the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor
can result in a risk of electric shock. The green conductor with
or without yellow stripes is the equipment-grounding conduc-
tor. If repair or replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding conduc-
tor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the tool’s plug.
Repair or replace damaged or worn cord immediately.
GENERAL INSTRUCTIONS
REMOVE ADJUSTING KEYS AND WRENCHES.
Form habit of checking to see that keys and adjusting
wrenches are removed from tool before turning on.
KEEP WORK AREA CLEAN. Cluttered areas and benches
invite accidents.
DON’T USE IN DANGEROUS ENVIRONMENTS.
Don’t use power tools in damp or wet locations, or expose
them to rain. Keep work area well lighted.

IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS

SET-UP:
The WC600D is supplied with one 3/32" Allen wrench,
one 5/32" Allen wrench and one 5/64" Allen wrench.
Bushing must be purchased separately.
CAUTION:
The WC600D blade is intended for use on soft flexible
tubing. However, some rigid tubing and some wire may be
cut. The blade is a very thin sharp blade and caution
should be used when handling it.
Place the Model WC600D on a sturdy workbench with the
right corner of the exit opening even with the right corner
of the bench. Short and long cut lengths will drop out the
side of the exit bushing. Material collection bins can be
placed to collect the cut material as it exits the unit. If
using the DE700 (or any other tensioning dereeler), place
the dereeler to the left side of the unit, at least 24" from the
entrance bushing in a straight line and align the lower
pulley with the entrance bushing. If using the DE700, refer
to their operating manual for further set up details.
BUSHING INSTALLATION:
To aid in bushing installation refer to the drawing. If
different sizes of material are going to be cut, additional
bushing sets may be ordered. There are three guide
bushings, the entrance, head, (or middle) bushing, and
exit bushing. First install the longer head bushing. Locate
the chamfered side of the bushing, this is the side that
goes in first. Slide the bushing in as close as possible to
the belt feed and back toward the blade, without hitting the
blade. Manually close the blade and check that the head
bushing is not touching the blade. Tighten the head
bushing in place. Insert the exit bushing in place. Manu-
ally close the blade, position the exit bushing as close to
the blade as possible. Tighten exit bushing in place. Make
certain that the blade moves freely by manually closing
the blade. Reposition the bushings if necessary. Install
the entrance bushing (chamfer side out) making certain
that it does not interfere with the belts when they are in the
fully closed position. Keep the bushings as close as
possible to the blade. This will provide the squarest cut
and allow the shortest pieces of tubing to be run. Bush-
ings that are not close to the blade will allow jamming of
short cut pieces.
Connect the power cord to the IEC connector, and plug
the unit into the appropriate power supply (either 115V
60Hz OR 230V 50Hz).
Place the material to be cut on the dereeler. Turn the
WC600D on using the I/O switch on the back side of the
unit. To open the front cover, unscrew the top and front.
The display will read “cover open system disabled” if the
cover is open or if the unit is in a run program. Back out
the belt feed adjusting knob by turning the adjusting knob
counter clockwise on belt roller tension adjuster. Feed the
tubing through the entrance bushing, between the belts
into the head bushing and through the exit bushing. To
tighten the upper and lower belts, simply turn belt adjust-
ing knob clockwise. The belt roller adjustment will prevent
tubing from being compressed, but it can also affect
length. If the material is slippery, more tension may be
applied to the belt feed by turning the tension adjusting
knob clockwise. Apply only enough tension to transport
the material. Do not over- tighten the belts. Over tightening
the belts may cause the material to crush thus creating
excessive drag in the transport bushing. The belts should
be adjusted by tightening them until the material (tubing)
can no longer be pulled between the belts. More belt
pressure may be added if the cut lengths are inconsistent.
Once material has been fed through the bushings and belt
tension is set, close the cover and use the jog button to
feed the material manually, and the cut button to cut it off.
The unit now is ready for programming. Note: The material
can be fed manually as described above or by jogging the
material through the bushings. To feed with the cover
closed, press the Jog button to enter the manual mode
and press the Jog button again to jog the material through
the entrance/cut bushings. If the material does not feed,
it can be inserted with the guard open. If in the manual
mode the unit can jog, rotate and cut the material. Press
the jog or cut keys to move or cut material. The speed of
the jog and cutter head will be determined by the last
inputted variables placed in the microprocessor.
PROGRAMMING:
START UP: When the unit is turned on, the controller will
report that it is initializing and display The Eraser Co/
WC601B. The line being edited will display a blinking
cursor. The system will then automatically display the
batch screen:
Do one of these: 0 (Enter 1)
Enter 0 for no batch
Enter known batch #__
Enter new batch #__
The number on the first line will be the last batch run, or
in this case, 0, since this is the first run since the system
was powered up. The number on the last line is the next
available batch that has not yet had parameters stored.
The system requires that batches be created in se-
quence, so numbers higher than the number on the last
line will not be accepted. As batches are created, the
number on the last line will increase, until the current
maximum of 99 batches is reached.
Press enter to select the default, or type in a new number.
If 0 is selected, all parameters will be set to zero, and will
be entered manually. Parameters entered while using
batch 0 are never stored. Parameters for all other batches
MODEL WC600D AUTOMATIC TUBING CUTTER
OPERATING INSTRUCTIONS

are stored, so the next time that particular batch is called,
those parameters will be presented as defaults. If any
parameters are edited, the new values will be stored for
the next time that batch is entered. All batches that have
parameters stored can be edited by entering the desired
batch number.
CREATING A NEW BATCH:
Enter the number on the last line of the batch prompt
screen, in this case 1. The first edit screen will appear:
Length units IN #1 (Use + or - key to change to
MM)
Length 0.000
Length compensation 0
Quantity 0
The current batch number is shown beside the # at the top
right. The cursor will be flashing just before the in (inch),
indicating that the field is currently editable. Press ENTER
to accept the default of inches, or press the + or - key to
toggle to mm, for millimeters, then press enter to store mm.
Each time ENTER is pressed, the cursor advances to the
next parameter.
Enter a value for the length parameter. If ENTER is
pressed accidentally before a value is entered, a long error
beep will sound, otherwise the entered value will be
stored. If a mistake is made, press the BS key to back
space over the entry. If the enter key has been pressed,
press the ESC key and start over. All values entered so
far will have been stored, so you would only have to press
ENTER until you returned to the place where you wanted
to make a change—the values would not have to be
entered again. Any value between .001 and 999,999,999
may be entered, or 0 to 9 digits, including a decimal point.
This allows for 5 digits before the decimal place and 3
after. In mm mode, only 2 decimal places are allowed after
the decimal point.
Due to variations in materials, actual cut length may vary
from the inputted length by a constant amount. The
WC600D and incorporate a length compensation feature
to provide an easy adjustment in these cases. The length
can be compensated +/-1% to 99% of the inputted length.
The length compensation display will show (-) for a
negative value. Example: If 10" (254mm) is entered as the
desired length, but the actual cut pieces measure 9.8"
(249mm), a length compensation of +2% will increase the
cut length by .200 (5mm) to the desired 10" (254). The
length compensation will remain with the batch program.
To use compensation, enter a value or use the + or - keys.
If no compensation is needed, press enter.
ENTER THE QUANTITY OF CUT DESIRED - UP TO 999,999.
Rate Screen
Feed Rate 1 (Enter 1 thru 5)
Initial Rate
Final Rate
Acceleration
After the quantity is entered, the rate edit screen appears.
Press + or - to increment or decrement the feed rate value.
Alternately, the desired feed rate may be entered manually
(any number between 1 and 5). As the value is changed, the
rate values are updated to show what values are active for that
feed rate.
Feed Rate 1=2.92 *IPS (74.2mm)
2=10.59 *IPS (269mm)
3=17.37 *IPS (441MM)
4=20.76 *IPS (527MM)
5=34.08 *IPS (865MM)
*Inches Per Second
NOTE: The slower the feed rate, the more accurate in length
the cut pieces will be. It is advised to start with the lowest feed
rate and check results, then adjust the feed rate if desired.
Cutter Screen
Cutter Parameters
Cut Speed (Enter 1 thru 5)
Cut Time (Average .4 thru .7 seconds)
The cut speed controls the speed and pressure at which the
rotary blade cuts through the material. If material does not cut
completely through, increase the speed control. If cut is not
clean enough, decrease the speed control. The cut time can
be changed for materials of different hardness. Average cut
on times are from .4 seconds to .7 seconds. The blade speed
and cutter on time should be set as low as possible to give
the best possible cut.
Cut Speed 1= 520 RPM
2= 522 RPM
3= 600 RPM
4= 652 RPM
5= 680 RPM
After the Cut Time is entered, the display under Cut Time will
show: Press Run to Start. Press Run or Enter to begin the
cutting cycle of the tubing cutter.
Run Screen
Pieces 10 #1
Length 1.000 IN
Feed Rate 3 10(compensation factor)
Pieces Left #
If the compensation factor is non-zero, its value will be printed
on the same line with the feed rate. The system will wait till
the RUN or ENTER key is pressed. Once started, the number
of pieces left is updated as the run progresses.
PAUSE FUNCTIONS
To interrupt a run at any time, depress the ESC key once
to stop the unit after the current feed/cut cycle is com-
pleted. Press the ECS key again to stop the unit imme-
diately. Depressing the ESC key twice quickly will stop
the unit immediately. When the key is released, the
message paused will appear on the bottom line. The

system can be opened and worked on, only if the material
does not extend past the exit bushing. Then close and
restart by pressing the RUN or ENTER key. If the material
is extending past the exit bushing, press the CUT key to
cut and remove the cut piece to allow the guard to open.
While paused, the length compensation may be edited
with the +/- keys. Material may be fed using the JOG key.
By depressing the JOG key, material will be fed with the
length being displayed. Each time a manual cut is
performed, the length is reset back to zero. The feed rate
may be changed while paused by pressing EDIT and
selecting a new feed rate.
Press ESC/PAUSE when paused to abort the run and
return to the Batch Prompt screen. When the run is
complete, the message Run Complete will appear on the
bottom line.
OPERATION:
The WC600D will not operate unless the front cover is
closed. If the cover is opened during a run the unit will stop
and the screen will display “cover open/system disabled.”
The system cannot be run until the cover is closed and the
display reads “ready to run/any key continues.” Pressing
the ESC/PAUSE key will return to the run screen in the
pause mode. Pressing the RUN key will immediately
resume the run.
POWER FAILURE:
In case of a power failure, the WC600D will be reinitialized
and will not start unexpectedly. All parameters stored in
a batch program will remain in memory. Parameters in
the 0 batch will be lost. The controller is protected by a
fuse located in the back of the housing just above the IEC
connector.
BLADE CHANGE, OR REPLACEMENT AND
BLADE DEPTH ADJUSTMENT
CAUTION: BE SURE UNIT IS UNPLUGGED BEFORE
CHANGING BLADES.
To replace the blade, with the front cover open, find the
exit bushing. Next, remove one of the screws holding the
blade in place, with the 5/32" Allen wrench provided and
loosen the other one. Slide the blade out from under the
screw and washer. Replace blade, screw, and tighten.
NOTE: If this is the first time the blade has been dulled,
it may be used again by turning the blade around and
using the other side. The cutting edge of the blade is
offset, so the blade may be used twice.
To adjust the depth of the blade, locate the socket head
cap screw located on the rotary head and loosen the
locking socket head set screw, which locks the socket
head cap screw in place, using the 3/32" Allen wrench
provided. To adjust the blade deeper, turn the socket
head cap screw using the 5/32" Allen wrench provided
counterclockwise. To raise the blade, turn the screw
clockwise. NEVER ALLOW THE BLADE TO GO PAST
CENTER OF BUSHING! Blade depth is properly set when
the blade is slightly deeper than the inside wall of the
tubing being cut. After adjusting the blade depth, tighten
the locking socket head set screw to keep the blade from
moving.
MAINTENANCE:
CAUTION: BE SURE TO UNPLUG THE UNIT BEFORE
PERFORMING ANY MAINTENANCE. BE SURE TO
EMPLOY APPROPRIATE ANTI-STATIC PROCE-
DURES/DEVICES WHEN DISASSEMBLING AND AS-
SEMBLING UNIT.
1. Check the blade for wear after prolonged use. Due to the
number of different materials, this maintenance should be
reviewed by your plant maintenance personnel and adjusted
accordingly.
2. No other maintenance is required for the units.
TROUBLESHOOTING:
PROBLEM: The blade does not move and is stuck in a
closed position.
SOLUTION: Adjust the blade as described in the blade
change or replacement section: Head or exit bushings
may be adjusted too close to the blade.
PROBLEM: Material does not feed properly through the
bushings.
SOLUTION:
1. Tighten the belt-feed adjusting knob clockwise to
increase the belt pressure on the material.
2. Check the blade and bushing position. Readjust if
necessary.
