The Tregaskiss 401-6-50 is a heavy-duty copper MIG welding nozzle designed for the TOUGH LOCK™ consumable system. It features a 1/2-inch tapered bore and a 1/8-inch tip recess, engineered for high-amperage industrial fabrication. The nozzle is constructed from hard-drawn copper with high-temperature fiberglass insulators to isolate it from the diffuser, and a heavy-duty crimp to maintain structural integrity across its three-layer design.
Features
High-conductivity hard-drawn copper construction
High-temperature resistant fiberglass insulators
Heavy-duty crimp construction holding three layers together
Smooth surface finish to minimize weld spatter accumulation
