Model BTS1 Thermal Wire Stripper
SET UP:
Place the BTS1 on a surface at a comfortable work height.
Set the temperature control to zero and the on/o switch
to “o” on front panel, then plug the power cord into the
I.E.C. outlet in the rear of the unit and the other end into an
appropriate power outlet. The unit has a self-contained fume
extraction system. Do not place unit directly against a wall.
Strip Length Setting - Set strip length by rotating the black
knurled knob located along the left side of the lower element
assembly (see Figure 1). Adjust the length stop plate until
the desired strip length is achieved.
Temperature Setting - With the temperature setting knob
(located on the control panel ) set at “0” slowly increase the
temperature until the elements soften and penetrate the
insulation. Ideally, the temperature control should be set at the
minimum temperature required to slit through the insulation,
for example, Teon insulation strips at approximately an
80% setting where as PVC insulation might strip with as low
as a 30% setting. Once the temperature is set for a given
insulation, the temperature setting will have the same eect
for all similar insulation materials.
! CAUTION: Excessive temperature causes greater
oxidation of the elements and can create excess fumes
from burning insulation.
Element Depth Setting - Set the element depth with the
element depth control knob. Loosen the set screw located
on the front of the upper element assembly block (see
Figure 1). Set the element depth by rotating the element
depth control knob. The element depth should be set so
the element penetrates through the insulation, but clears
the conductor. Once the element depth is determined, lock
the elements by retightening the set screw located on the
front of the upper element assembly block. For elements
with specied wire sizes (optional factory die elements),
simply adjust the element depth knob so that the upper
and lower elements meet. Once the element depth setting
is adjusted, it should not require further adjustment until a
new wire diameter is introduced.
OPERATION:
Switch the unit on using the on/o switch on the front
panel. After determining the best stripping temperature,
insert wire between elements to the length stop plate,
press down on a ball knob located on either side of the
upper element assembly (optionally, depress footswitch).
Rotate the wire in the elements to penetrate the entire
circumference of insulation. Remove wire and manually
remove the insulation slug.
MAINTENANCE:
IMPORTANT NOTE: Always turn the unit o, disconnect
the power cord, and wait until the elements have cool down
before servicing the unit. Clean insulation build-up from
stripping elements periodically with anAA0020 Coarse Eraser
Brush. Ensure the element retaining screws are always tight
to ensure good electrical contact with the electrode bars.
Also, periodically, clean the contact area of the electrode
bars and the elements of any oxidation build-up with the
Coarse Eraser Brush.
Installing Optional ElementActivation Footswitch - Place
the footswitch on the oor, then plug it into the outlet in the
rear of the unit. The footswitch when depressed activates
the closing of the elements around the wire.
Installing the Optional 90 Degree Adaptors - Turn the unit
o and disconnect the power cord. (Always wait until the
two elements have cooled down before servicing the unit).
Remove the elements from the ends of the electrode bars
by removing the four retaining screws. Remove the clear
guard by rst removing the element depth control knob,
remove the knob by loosening the set screw located on
the collar of the knob then pulling it o the threaded shaft.
Remove the three button head screws securing the clear
guard. Adjust the length stop plate so that its position is as
far back as it will go. All the adaptors' pieces are identical,
fasten the adaptors to the four elements creating two adaptor
assemblies (see Figure 2). Fasten the adaptor assemblies
to the vertically tapped holes near the ends of the electrode
bars using the screws and washers provided. Fasten one
assembly to the top of the upper left element electrodes
and one to the bottom of the lower right element electrodes.
TROUBLESHOOTING:
PROBLEM: Unequal heating of elements.
SOLUTIONS:
1) Remove elements and clean oxide from contact points.
2) Reinstall element set and ensure screws are tightened
completely.
PROBLEM: Poor stripping results.
SOLUTIONS:
1) Check element for wear or corrosion.
2) Clean or replace as needed.
3) Adjust temperature and element depth until desired
results are achieved.
PROBLEM: Unit does not operate.
SOLUTIONS:
1) Ensure unit is plugged into appropriate power source.
2) Unplug power while verifying. Check fuse. Replace if
blown.
