Eraser WC600 User manual

Set Up:
The WC600 is supplied with three sets of entrance/
exit bushings. The 5/16" (7.94mm) bushing set is
installed in the unit, and the 1/8" (3.17 mm) and 1/
4" (6.35 mm) sets are bagged as accessories. Cus-
tom bushing sets are available as options, contact
factory for details.
The unit also includes two blades, one designed for
cutting wire, and one for flexible tubing. The tubing
blade (thin, pointed blade) is installed in the unit and
the wire blade (blunt, flat blade) is bagged as an
accessory. Custom blades are also available, con-
tact factory for details. Also included as accessories
are three Allen wrenches, 5/64", 3/32" and 1/8".
CAUTION: DO NOT use the tubing blade to cut wire
as this will severely damage the blade. Also, use of
the wire blade to cut tubing will result in distorted
cut ends.
The WC600 should be used with a tension dereeler
for most applications. Use of the Model DE700
Compensating Dereeler is recommended. CAUTION:
Improper tensioning of the material, caused by use
of an incorrect dereeler, may cause inconsistencies
in cut lengths.
Using the carrying handles on the sides of the unit,
place the WC600 on a sturdy workbench. We rec-
ommend the unit be positioned so that the right cor-
ner of the exit chute is even with the right corner of
the bench. Short cut lengths will roll out the front
of the exit chute, and long lengths will exit out the
end of the chute. Place a suitable material collec-
tion bin underneath the exit chute to catch cut pieces.
If using the DE700 (or any other tensioning dereeler),
place the dereeler to the left side of the WC600, at
least 24" from the entrance bushing in a straight
line, and align the lower pulley of the DE700 with
the entrance bushing of the WC600. If using the
DE700, refer to its operating manual for further set-
up details.
Connect the power cord to the IEC connector and
plug the unit into the appropriate power supply, ei-
ther 115V 60HZ or 230V 50HZ. NOTE: 230V units
are shipped without plugs. Wire on appropriate plug.
Color coding is brown=live, blue=neutral,
green=ground.
Place the material to be cut on the dereeler. If the
material is wire, it will be necessary to change the
blade in the unit, see next page for instructions. Also,
if the material requires the use of the 1/8" (3.17
mm) or 1/4" (6.35 mm) bushing sets, it will be nec-
essary to install these, see next page for instruc-
tions. With the proper blade and bushings installed,
open the cover of the WC600 by pulling up on it
gently to release the magnetic catch. Feed the ma-
terial into the entrance bushing and raise the feed
roller using the lifter. If necessary, the feed roller
may be locked in the lifted position for easier feed-
ing of the material. Feed the material between the
feed rollers, and through the exit bushing of the
WC600. Release the feed roller and adjust the roller
tension for the material using the adjusting knob on
top of the roller. Clockwise rotation of the knob will
result in more tension, counterclockwise rotation will
result in less tension.
Close the cover, and turn the unit on using the I/O
switch at the back of the unit. Press "Jog" to move
material forward slightly, and "Cut" to cut off a piece.
The unit is now ready for programming.
Operation:
The Batch Screen appears on the keypad display
upon power-up. If you wish to program in a one-
time only run, enter "0" for no batch. Run param-
eters will not be stored if no batch number is en-
tered. If you wish to create a batch, enter the num-
ber shown after "Enter new batch #". Once a batch
has been created, it can be run again simply by in-
putting its batch number on the Batch Screen.
Once "0" or the next batch number has been en-
tered, the Edit Screen appears. The first line indi-
cates the length units for this batch or run is inches.
To change to millimeters, use the plus (+) or minus
(-) keys to toggle. Press "Enter". The cursor will
advance to the length value. Enter the desired length.
If a mistake is made, press the "BS" key to back-
space over the entry. Length values from .001 to
999,999.999 may be entered in the inches mode,
with two decimal places in millimeter mode. When
the desired length is displayed, press "Enter".
The next value is length compensation. The default
is 0, or the + or - keys may be used to add or
decrease length compensation of plus or minus 1 -
99% of the inputted length. NOTE: Often it will not
be known if length compensation is needed until after
a run is completed. If programming a batch, leave
the field at 0 and edit the batch later if necessary to

add length compensation. Once a value has been
entered, or if the default of 0 is to be used, press
"Enter".
The next value is the quantity of cut pieces desired
in the run. Enter any value from 1 to 999,999.
Press "Enter". The Rate Screen will now appear.
Press the + or - key to increment the feed rate from
1 to 5, or enter the number of the desired feed rate
if known. As the value is changed, note that the
rate values are automatically updated to show the
data relevant to the selected feed rate. When the
desired feed rate shows, press "Enter".
The Run Screen now appears. It shows the input-
ted length, quantity, feed rate, and compensation
value if used. If all parameters are correct, press
"Run" to start the run. The number of pieces left
will be updated as the run progresses. When the
run is complete a "Run Complete" message will ap-
pear on the display.
To interrupt a run at any time, press the "Esc/Pause"
key until the unit stops. The word "Paused" wil
appear on the display. The unit can be opened and
feed tension adjusted if necessary, then closed and
restarted by pressing "Run" or "Enter". While in
Pause, the length compensation and/or feed rate may
be edited, and material may be fed using the "Jog"
key and cut using the "Cut" key. To cancel the
remainder of a run while in Pause, press the "Esc/
Pause" key.
NOTE: The front cover of the WC600 must be com-
pletely closed in order for the unit to run. If the
cover is opened during a run the unit will stop and
display "Cover open/system disabled". The cover
must be closed, and the display will read "Ready to
run/any key continues". Press "Esc/Pause" to re-
turn to the Run Screen or "Run" to continue the run.
In the event of a power failure, the WC600 will stop
and will not restart automatically upon resumption
of power. The unit must be turned off and turned
back on again. All parameters stored in batch
memory will remain in memory, but any information
in a 0 batch that may have been running at the time
of the power failure will be lost.
Programming Note: If "Enter" is pressed before a
value is entered in a field, a long error beep will
sound. If a mistake is made in entering a value, use
the "BS" key to backspace over the entry. If "En-
ter" has not been pressed after a value is inputted,
press the "Escape/Pause" key and start over at the
field affected.
Blade Change or Replacement:
The WC600 is supplied standard with an angled tub-
ing blade installed, and a straight wire blade as an
accessory. The tubing blade must not be used on
wire as it will be severely damaged. The wire blade
should not be used on tubing as it will not give a
square cut. Optional special blade configurations are
available for applications that do not give good re-
sults with either standard blade. Contact factory for
details.
Caution: Be sure unit is unplugged before changing
blades. Open the front cover and locate the front of
the exit chute. Loosen the button head cap screw
holding the exit chute, and slide the chute to the
right to remove it. Locate the knuckle at the front
of the solenoid which holds the blade. Using the 3/
32" Allen wrench provided, remove the shoulder
screw in the knuckle. Slide the blade forward through
the blade block and remove. Caution: The blades
are extremely sharp, handle carefully to prevent in-
jury. To install a new blade, reverse the procedure.
Once the new blade is in, it may be necessary to
adjust the blade pressure. To do this, loosen the 1/
2" nut and back out the socket head cap screw us-
ing a 1/4" Allen wrench. To adjust, tighten the socket
head cap screw while sliding the blade back and
forth until some friction is felt. Then tighten the nut
while holding the screw in place. If the blade is too
tight it will remain in the forward position. Loosen
again and readjust. Reinstall the exit chute and close
the front cover.
Bushing Set Change or Replacement:
Caution: Be sure unit is unplugged before changing
bushings. The WC600 is supplied with the 5/16"
(7.94 mm) ID entrance and exit bushings installed,
for use with material between 1/4"(6.35mm) and 5/
16"(7.94) mm. OD. For the best cut results and
accuracy, the entrance and exit bushings should
match the material size as closely as possible. There-
fore it may be necessary to change to the 1/8" (3.17
mm) or 1/4" (6.35mm) standard bushing sets pro-
vided, or to a custom bushing set (optional). To
change the entrance bushing, open the front cover.
Loosen the set screw in the entrance bushing sup-
port with the 3/32" Allen wrench provided., and slide
the bushing out. Insert the desired entrance bush-
ing, aligning the flat with the set screw, and tighten.
Be sure the entrance bushing does not come in con-
tact with the feed rollers.
To change the exit (cut) bushing, loosen the button

head cap screw holding the exit chute with the 3/
32" Allen wrench provided. Remove the exit chute
by sliding it to the right. Locate the set screw hold-
ing the exit bushing. While holding the exit bushing,
insert the 3/32" Allen wrench into the front plate in
line with the exit bushing, and loosen the set screw.
Remove the bushing by sliding it toward the feed
rollers. Slide the new exit bushing into the back of
the cut plate and align the ground surface of the
bushing with the ground surface of the cut plate.
Using a straight edge or flat piece of metal, align the
cutting edge of the exit bushing with the surface of
the cut plate. Tighten the set screw on the flat on
the side of the exit bushing.
IMPORTANT: The new bushing MUST be properly
aligned with the cut plate to ensure squareness of
cut and blade and bushing life.
Reinstall the exit chute assembly and close the front
cover.
Feed Roller Change or Replacement:
The WC600 is fitted as standard with a carbide
coated lower feed roller and a urethane coated up-
per feed roller. These work well for most applica-
tions. However, if cutting bare wire or wire with
soft insulations, the carbide feed roller may cause
some marking on the material. To eliminate this,
the optional IR5171 urethane coated lower roller may
be purchased. Also, for slippery materials, the op-
tional IR5167 knurled lower roller may be purchased.
Caution: Be sure unit is unplugged before changing
feed roller. To change the feed rollers, first open
the front cover. To remove the upper feed roller,
remove the socket head shoulder screw in the cen-
ter of the feed roller using the 1/8" Allen wrench
provided. Slide the roller off the unit. Install the
screw in the new feed roller, slide the roller onto the
unit, and retighten. It may be necessary to raise the
feed roller using the lifter and lock it in place while
reinstalling the screw. To remove the lower feed
roller, loosen the set screw in the hub of the roller,
using the 5/64" Allen wrench provided, and slide
the roller off the motor drive shaft. Install the new
roller on the shaft, and align the set screw with the
flat on the motor shaft. Align the front edge of the
lower feed roller with the front edge of the upper
feed roller and tighten the set screw. Close the front
cover.
Maintenance:
Caution: Be sure to unplug the unit before perform-
ing any maintenance. Also, employ appropriate anti-
static procedures and devices when assembling or
disassembling the unit.
Check the cut bushing and blade for wear periodi-
cally, and replace if dull. Due to the number of dif-
ferent materials, the timing of checks will need to
be determined based on the material being run.
Keep unit clean and free of dust and debris. No
lubrication or other regular maintenance is required.
Troubleshooting:

Set Up:
The WC600A will be delivered with three sets of en-
trance/cut bushings. The 3/8" (9.52mm) set is installed
in the unit, and the 1/8" (3.17mm) and 1/4" (6.35mm)
sets are bagged as accessories. Custom bushing sets
are available as options, contact factory for details.
The unit also includes two blades, one designed for
cutting wire, and one for flexible tubing. The tubing
blade (thin, pointed blade) is installed in the unit and
the wire blade (blunt, flat blade) is bagged as an
accessory. Custom blades are also available, con-
tact factory for details. Also included as accessories
are two Allen wrenches, 5/64" and 3/32".
CAUTION: DO NOT use the tubing blade to cut wire
as this will severely damage the blade. Also, use of
the wire blade to cut tubing will result in distorted
cut ends.
The WC600A should be used with a tension dereeler
for most applications. Use of the Model DE700
Compensating Dereeler is recommended. CAUTION:
Improper tensioning of the material, caused by use
of an incorrect dereeler, may cause inconsistencies
in cut lengths.
Using the carrying handles on the sides of the unit,
place the WC600A on a sturdy workbench. We recom-
mend the unit be positioned so that the right corner of
the exit chute is even with the right corner of the bench.
Short cut lengths will roll out the front of the exit chute,
and long lengths will exit out the end of the chute. Place
a suitable material collection bin underneath the exit
chute to catch cut pieces.
If using the DE700 (or any other tensioning dereeler),
place the dereeler to the left side of the WC600A, at
least 24" from the entrance bushing in a straight
line, and align the lower pulley of the DE700 with
the entrance bushing of the WC600A. If using the
DE700, refer to its operating manual for further set-up
details.
Connect the power cord to the IEC connector and
plug the unit into the appropriate power supply, ei-
ther 115V 60HZ or 230V 50HZ. NOTE: 230V units
are shipped without plugs. Wire on appropriate plug.
Color coding is brown=live, blue=neutral, green=ground.
The WC600A also requires a clean lubricated air sup-
ply which can deliver 3 CFM at 90 PSI. If the airline
does not already contain a lubricator and filter, the op-
tional PR0003 regulator/filter/lubricator may be pur-
chased. Connect the 6' long airline supplied with the
machine to a 1/4" female connector located at the rear
of the housing. The other end of the supply line may be
connected to a quick disconnect fitting.
Place the material to be cut on the dereeler. If the ma-
terial is wire, it will be necessary to change the blade in
the unit, see next page for instructions. Also, if it is
necessary to change bushings, see next page for in-
structions. With the proper blade and bushings installed,
open the cover of the WC600A by pulling up on it gently
to release the magnetic catch. Feed the material into
the entrance bushing and open the belt feed by turning
the adjusting knob counterclockwise. Feed the mate-
rial between the belts, and through the exit bushing of
the WC600A. If necessary to adjust the belt feed ten-
sion, clockwise rotation of the knob will result in more
tension, counterclockwise rotation will result in less ten-
sion.
Close the cover, and turn the unit on using the I/O
switch at the back of the unit. Press "Jog" to move
material forward slightly, and "Cut" to cut off a piece.

Blade Change or Replacement:
The WC600 is supplied standard with an angled tubing
blade installed, and a straight wire blade as an acces-
sory. The tubing blade must not be used on wire as
it will be severely damaged. The wire blade should
not be used on tubing as it will not give a square
cut. Optional special blade configurations are available
for applications that do not give good results with either
standard blade. Contact factory for details.
Caution: Be sure unit is unplugged and air cylinder
is disconnected before changing blades. Open the
front cover and locate the front of the exit chute. Loosen

blade pressure. To do this, loosen the 1/2" nut and back
out the set screw using a screwdriver. To adjust, tighten
the set screw while sliding the blade back and forth until
some friction is felt. Then tighten the nut while holding
the screw in place. If the blade is too tight it will remain
in the forward position. Loosen again and readjust. Re-
install the exit chute and close the front cover.
Bushing Set Change or Replacement:
Caution: Be sure unit is unplugged and air cylinder
is disconnected before changing bushings. The
WC600A is supplied with three sets of bushings. For
the best cut results and accuracy, the entrance and exit
bushings should match the material size as closely as
possible. Therefore it may be necessary to change
bushings periodically if different materials are to be cut.
To change the entrance bushing, open the front cover.
Loosen the set screw in the entrance bushing support
with the 3/32" Allen wrench provided, and slide the bush-
ing out. Insert the desired entrance bushing, aligning
the flat with the set screw, and tighten. Be sure the
entrance bushing does not come in contact with the feed
belts.
To change the exit (cut) bushing, loosen the button head
cap screw holding the exit chute with the 3/32" Allen
wrench provided. Remove the exit chute by sliding it to
the right. Locate the set screw holding the cut bushing.
Insert the 5/64" Allen wrench into the front plate in line
with the cut bushing, and loosen the set screw.

The WC600 is fitted as standard with a carbide coated
lower feed roller and a urethane coated upper feed roller.
These work well for most applications. However, if cut-
ting bare wire or wire with soft insulations, the carbide
feed roller may cause some marking on the material. To
eliminate this, the optional IR5171 urethane coated lower
roller may be purchased. Also, for slippery materials,
the optional IR5167 knurled lower roller may be pur-
chased. Caution: Be sure unit is unplugged before
changing feed roller. To change the feed rollers, first
open the front cover. To remove the upper feed roller,
remove the socket head shoulder screw in the center of
the feed roller using the 1/8" Allen wrench provided. Slide
the roller off the unit. Install the screw in the new feed
roller, slide the roller onto the unit, and retighten. It may
be necessary to raise the feed roller using the lifter and
lock it in place while reinstalling the screw. To remove
the lower feed roller, loosen the set screw in the hub of
the roller, using the 5/64" Allen wrench provided, and slide
the roller off the motor drive shaft. Install the new roller
on the shaft, and align the set screw with the flat on the
motor shaft. Align the front edge of the lower feed roller
with the front edge of the upper feed roller and tighten the
set screw. Close the front cover.
Maintenance:
Caution: Be sure to unplug the unit and disconnect
the air supply before performing any maintenance.
Also, employ appropriate anti-static procedures and
devices when assembling or disassembling the unit.
