More heat protection than your standard LC-40. The Specialty PowerLock™ combines a heavy-duty 300A connection with a high-temperature fiberglass sleeve designed to withstand extreme heat and resist melting like traditional connector housings.
The added thermal protection helps keep the outside cooler and more comfortable to handle when disconnecting after high-amperage welding.

WHAT MAKES US DIFFERENT
Heat Absorbing Tig Adapter
Our PATENT TIG adapter is specifically designed for use with any model of Flex Heads (F26). Its primary function is to manage the heat generated between the lead and the TIG rig head. This ensures that the head remains cooler, allowing it to run at higher amperages compared to other TIG rigs.
Heat Resistant Argon Hose
Our heat-resistant argon hose is uniquely designed to endure contact with hot surfaces, including weld puddles, if your TIG rig accidentally encounters them. Engineered to withstand extreme temperatures without damage or melting, its durability is demonstrated at the top of this page.
Heat Resistant/Most Light/Flexible Welding Cable
Our welding lead is constructed from 100% pure twisted copper, specifically designed to be the lightest and most flexible cable available for two-piece rigs. Engineered for durability, it ensures the copper remains intact with out burning out even after many years of use.
