Quick Overview

Battery Powered tool designed to strip High-Temperature Insulation (PTFE etc.) from wires and cables #8 AWG.


Replacement Elements are sold only in 5 pcs. per pack.



PTS-40HDS Thermal Wire Stripper is battery powered tool, which far surpasses all previous devices in safety, versatility, speed, and economy. The patented design incorporates a uniquely shaped spring temper Nickel-Chromium heating element, which heats up quickly (less than 4 seconds) to an optimal temperature of 1700°F. The tool will efficiently strip High-Temperature (PTFE etc.) insulation from # 8 AWG  solid or stranded wires and can produce over 100 strip per full charge.

The extremely thin heating element produces negligible amount of fumes and therefore the use of these strippers does not require special ventilation. The fumes produced by thick element designed tools should be exhausted.

The low mass, guarded element design minimizes the risk of burns, eliminates nicks and broken strands of conductors and reduces lead pull on sensitive components. This comfortably sized handheld tool operates on single “D” cell rechargeable 1.2 Volt NiMH  battery.

The element design features two sections. Ringing section (a heated section where the insulation is thermally separated) and pulling section where the thermally separated insulation slug is wedged between two parallel edges of the stripping element for an easy removal. Although this section of the element also carries the current which heats the grooving section, it is not annealed (due to its greater widths and therefore much lower resistance) and it retains its hard temper. In addition, these edges are also supported by .025″ thick, hard temper element support. This will allow pulling long slugs of insulation without damaging the element. The stripping element is only .010″ thick (.008″ PTS-10) and therefore the thermally cut groove width is much narrower than the two element models offered by other manufacturers. This low mass thermal stripping technology means less power, faster heating time, shorter cooling time, less fumes and higher quality strip. The longevity of the element is also greatly extended because the annealed portion of the element is used for ringing (separating) the insulation rather than pulling off the slug.

Of course, there are no nicks because of the rounded edges of the stripping element. The heated section of the element is also protected by an element guard, thus reducing the risk of burns. The segmented design of the studs helps dissipate heat thus reducing the risk of burns even in prolonged use. The weight of the PTS-40HDS tool is 14oz. (0.4 kg.) and the weight of the PTS-3HDS Adjustable Temperature model is 5.2 oz. (0.150 kg.).

Each model is equipped with different element mounting hardware which must be assembled in a certain order otherwise the tool will not work properly. Please carefully observe close-up pictures of the 5 available models to see the difference in element mounting hardware. It is not economical to keep switching elements and hardware designed for other models in order to extend the wire stripping range of a single tool.

The flicker accessory is provided to flick off the sometimes wedged in insulation slug for continuous and uninterrupted stripping.


We do not recommend switching High-Temperature stripping elements once fully energized (DISCOLORED)!

The discolored portion of the element was annealed. It lost its strength. It bends and distorts easily! It can be therefore easily damaged when screwed and tightened to the posts. The damage is caused by friction and torque transferred to the element in the process of screw tightening.


The operator may remove insulation with this tool because of a fixed calibrated stripping section, which eliminates conductor scraping.  Weapons specification WS-6536E does not permit this when other thermal strippers are used.
