Meisei HOTWEEZERS & HOTNIFE Thermal Wire Strippers

The Meisei HOTWEEZERS and HOTNIFE series are professional-grade thermal wire strippers engineered for precision, consistency, and clean stripping of heat-resistant insulation materials. These tools are designed for demanding environments where conventional mechanical strippers fail—particularly when working with high-temperature wire insulation such as PTFE (Teflon), TEFZEL, silicone rubber, or Kapton. Whether used in aerospace, electronics assembly, or R&D labs, Meisei thermal strippers deliver high repeatability and minimal conductor damage.

The HOTWEEZERS thermal wire stripper line uses heated tweezer-style blades to cleanly strip off the insulation without nicking or deforming the wire. These units support fine-gauge wire ranging from AWG 36 to AWG 18, making them ideal for applications involving delicate micro cables, ribbon assemblies, or mil-spec harnesses. The blades are interchangeable and available in several profiles to match specific wire sizes and insulation types. Some of the HOTWEEZERS models are ESD-safe, ensuring compatibility with static-sensitive environments.

For larger insulation profiles and specialty cutting jobs, the HOTNIFE thermal stripper is a blade-style hot knife system designed to slice through thick or braided insulation using high heat. Unlike mechanical cutters, the HOTNIFE system reduces strain on conductors by heating the insulation just enough to melt it away. It's particularly effective on silicone, fiber-reinforced sleeving, and high-durometer jacketing. With rapid thermal cycling and precise heat control, Meisei HOTNIFE tools excel in bench-top production environments.

Both tool systems interface with Meisei M-10 and M-20 thermal power supplies, which provide adjustable temperature control, stable output, and support for either hot knife or tweezer-type handpieces. The modular design makes it easy to switch between tool types or upgrade as needs evolve. These systems are highly regarded for their low maintenance requirements, rugged build quality, and long-term reliability under continuous use.

Common applications for Meisei thermal strippers include high-reliability cable assemblies, avionics harnesses, medical device wiring, satellite electronics, and prototyping labs. Because they eliminate mechanical strain during insulation removal, they help maintain conductor integrity—especially important when working with fine strands or silver-plated wire.

Compared to other brands the Meisei HOTWEEZERS offers superior build quality, consistent blade heat distribution, and broader compatibility with legacy and modern wiring standards. Their products are widely used by aerospace contractors, OEMs, and high-end electronics manufacturers. This product has been their entire business focus for the last 50 years!

Vetco Electronics is also first to offer their brand new digital M-30 Series & Adapters. This new model is compatible all around the world and has upgraded features the old model does not. Any Questions please ask!
