HTS1 THERMAL
WIRE STRIPPERS
HTS Series Overview
The HTS (Hand Thermal Stripper) series are portable,
lightweight & variably controlled handheld thermal
strippers for stripping solid and stranded conductor
wires. The HTS strips a variety of extruded insulation
materials. Several congurations of stripping elements
are available and elements are easily changeable.
The HTS units are designed for intermittent use for
maximum element performance and operator comfort.
The 2 models in the HTS series are the HTS1F and
the HTS1C. Model HTS1F includes a foot pedal that
powers the stripping elements only when the foot pedal
is depressed. This model is suited for on-demand
operation. Model HTS1C model has a switch in the
handpiece cradle that powers the stripping elements
as soon as the handpiece is lifted from the cradle. This
model is ideal for high volume applications.
A FybRglass® abraser is provided for the purpose of
cleaning the stripping elements periodically. See the
Maintenance section for more details. Depending on
the materials being stripped, fume extraction may be
required. See the Ordering Information section for
more details.

OR FOR A PURPOSE FOR WHICH THE PRODUCT WAS
NOT DESIGNED.
SET-UP (both models) (Refer to Figures 1 and 2)
Insert the IEC power cord into the back of the
temperature control unit. Make sure that the power
switch is in the OFF (O) position before plugging the
power cord into the appropriate electrical outlet. Place
the temperature control unit on a at and level bench
surface. Lay the handpiece in the cradle, located on
the side of the temperature control unit.
!CAUTION: Whenever the HTS unit is not in use, the
handpiece should be placed in the cradle and the power
switch should be turned to the OFF (O) position. Never
set the handpiece onto any other surface.
Setting the Strip Length
NOTE: No power/heat is needed to set the strip length.
Before turning the unit on, set the strip length stop to the
desired point by loosening the strip length adjustment
screw with the supplied allen wrench. Slide the strip
length stop along the electrodes and retighten the
strip length adjustment screw when the desired strip
length is achieved. For strip lengths longer than 1.5”
(38 mm), remove the strip length stop by removing the
strip length adjustment screw from the strip length stop.
Then remove the strip length stop from the electrode.
The maximum strip length with the stop removed is
2” (51 mm).
!CAUTION: The heated stripping elements on the HTS
units can reach temperatures up to 1100°F (594°C).
Use extreme care whenever the handpiece is being
used. Elements should never come into contact with the
skin, unless they are fully cooled to room temperature
and the unit has been turned o󰀨 and disconnected from
the power supply.
Model HTS1F OPERATION (Refer to Figures 1
and 2)
Turn the temperature control knob to the ‘0’ dial setting
(fully counter-clockwise) and turn the power switch on
the temperature control unit to the ON (I) position. Pick
up the handpiece and hold it in one hand while holding
the wire to be stripped the in the other. Depress the
footpedal and insert the wire to be stripped between
the stripping elements up to the strip length stop. Close
the handpiece until the elements contact the insulation.
Stripping Wire (both models)
Gently squeeze the handpiece and slowly increase heat
to the elements by gradually turning the temperature
control knob clockwise from ‘0’until the elements cause
the insulation to soften and eventually sever. Continue
to gently squeeze the handpiece until the insulation is
fully severed/stripped. It may be necessary to rotate
the elements around the circumference of the wire
(approximately 90°) to ensure a complete separation
of the insulation.
NOTE: Always strip wires on the lowest possible heat
setting, as this will provide the highest strip quality, the
least amount of fumes and optimized element longevity.
Insulation slug removal (model HTS1F)
Once the insulation is fully separated, release the
footpedal to remove power from the elements. Open
the elements, remove the wire from the handpiece and
return it to the cradle. Manually remove the insulation
slug from the conductor using a slug removal tool or
pliers. NOTE: Do not use the handpiece/elements to
remove the insulation slug. The HTS is designed to
produce a removable (insulation) slug at the end of a
wire length- it is not designed to pull the slug o󰀨 the
end of the wire.
!CAUTION: Do not use bare hands/ngers to remove
the insulation slug from the conductor. A tool is
recommended for removal of the insulation slug. If the
slug must be removed by hand, either use gloves with
appropriate insulation or give the wire enough time to

HTS Series Thermal Hand Wire Strippers
cool to room temperature before removing the slug.
Setting the Strip Depth (both models)
NOTE: No power/heat is needed to set the strip depth.
Now the set-up piece (as stripped above) can be used
to set the depth of strip. With the conductor exposed,
set the element depth by backing o󰀨 (turning counter-
clockwise) the element depth adjustment screw on
the handpiece. Close the elements to contact/grip
the exposed conductor. Then slowly turn the element
depth adjustment screw clockwise until immediately
after the conductor is released from the ‘grip’ of the
elements, stopping so that the element opening (while
the handpiece is squeezed to its closed position) is
just slightly larger than the conductor’s diameter- the
closer the distance of the elements to the conductor
(without touching) the better. Element depth should be
set so that the elements will sever the insulation, but
not contact the conductor. This will insure consistent
and high quality stripping.
Once the correct temperature setting and element
depth have been set, they should not need changing
unless the wire size and/or insulation material changes.
Model HTS1C OPERATION (Refer to Figures 1
and 2)
Turn the temperature control knob to the ‘0’ dial setting
(fully counter-clockwise) and turn the power switch on
the temperature control unit to the ON (I) position. Pick
up the handpiece and hold it in one hand while holding
the wire to be stripped the in the other. The stripping
elements will automatically heat after the handpiece
has been removed from the cradle. Insert the wire
to be stripped between the elements up to the strip
length stop, and close the handpiece until the elements
contact the insulation.
Stripping Wire (both models)
Gently squeeze the handpiece and slowly increase heat
to the elements by gradually turning the temperature
control knob clockwise from ‘0’until the elements cause
the insulation to soften and eventually sever. Continue
to gently squeeze the handpiece until the insulation is
fully severed/stripped. It may be necessary to rotate
the elements around the circumference of the wire
(approximately 90°) to ensure a complete separation
of the insulation.
NOTE: Always strip wires on the lowest possible heat
setting, as this will provide the highest strip quality, the
least amount of fumes and optimized element longevity
Insulation slug removal (model HTS1C)
Once the insulation is fully separated open the elements,
remove the wire from the handpiece and return it to
the cradle. Manually remove the insulation slug, using
a slug removal tool or pliers. NOTE: NOTE: Do not
use the handpiece/elements to remove the insulation
slug. The HTS is designed to produce a removable
(insulation) slug at the end of a wire length- it is not
designed to pull the slug o󰀨 the end of the wire.
!CAUTION: Do not use bare hands/ngers to remove
the insulation slug from the conductor. A tool is
recommended for removal of the insulation slug. If the
slug must be removed by hand, either use gloves with
appropriate insulation, or give the wire enough time to
cool to room temperature before removing the slug.
Setting the Strip Depth
Refer to the Setting the Strip Depth section.
ELEMENT REMOVAL/INSTALLATION (Refer to
Figures 1 and 2)
To remove the stripping elements, use the supplied
screwdriver to loosen and remove the (4) element
mounting screws & washers (2 screws & 2 washers
per element). Using the supplied FybRglass® abraser
brush, remove any buildup or debris from the ends of
the electrodes so that there will be good conductivity
with the new elements. After cleaning all contact areas
between the electrodes and elements, loosely install
the new washers and screws, leaving enough space
so the elements can slide in between the washers and
the elements. Install elements and tighten the screws,
without over-tightening. Repeat the process so that both
the top and bottom elements are a󰀩xed. Insure that
all four (4) element mounting screws are equally tight.
NOTE: Make sure that the stripping elements are
secured squarely (meaning that the elements’ contact
with each other is continuous along the entire length
of the contact/stripping surface) when the handpiece
is closed. If the stripping elements are not square in
relation to each other, adjustments will be necessary.
To adjust the stripping elements for optimal alignment,
loosen all four (4) element mounting screws slightly
(enough so that both elements are retained, but still
moveable). Squeeze the handpiece to the closed
position and align the elements so they are parallel

HTS Series Thermal Hand Wire Strippers
and in full contact with each other. Re-tighten screws,
without overtightening. Repeat as necessary until
elements are parallel and in full contact with each
other when engaged.
MAINTENANCE
Maintenance for the HTS series requires periodic
cleaning of the stripping elements by using the supplied
FybRglass® abraser brush. Be sure to keep the contact
points on the stripping elements and the ends of the
electrodes as clean as possible and free of oxides.
Insure that all four (4) element mounting screws are
equally tight. Replace used stripping elements as
necessary (see above section).
TROUBLESHOOTING (Refer to Figures 1 and 2)
PROBLEM: Unit does not operate.
SOLUTIONS:
1. Insure that the temperature control unit is plugged
into the appropriate power source.
2. Insure that the power switch on the temperature
control unit is switched to the ON position.
3. Insure that su󰀩cient power is applied to the stripping
elements by slowly turning the temperature knob
clockwise from the ‘0’ position (see the Stripping
wire section).
4. If unit is still not functioning, switch the power to the
OFF position and unplug the temperature control
unit from the power source.
5. Check the fuse in the rear of the temperature control
unit and replace the fuse if it is blown. If fuse blows
a second time, contact the factory.
PROBLEM:Unequal heating of stripping elements.
SOLUTIONS:
1. Turn the temperature control unit to the OFF position
and unplug the unit from the power source.
2. Allow appropriate time to ensure that stripping
elements are cool.
3. Remove elements and clean oxides from contact
points (see the Maintenance and Element Removal/
Installation sections).
4. If elements continue to heat unequally after
cleaning, a new set may be required (see the
Element Removal/Installation section).
PROBLEM: Poor stripping results.
SOLUTIONS:
1. Be sure you are stripping at the lowest possible
temperature for the insulation type.
2. Adjust temperature and/or element depth until
desired results are achieved (refer to the model-
specic Operation section, the Stripping Wire and/
or the Setting the Strip Depth sections).
3. If stripping results are still poor after steps 1 & 2,
follow steps 1-4 above (under Unequal heating of
stripping elements).
