The Tregaskiss 401-50-62 is a heavy-duty, air-cooled bottleneck MIG welding nozzle belonging to the TOUGH LOCK™ Consumable Series. It is constructed from hard-drawn copper and designed for high-amperage industrial welding applications, including pulse welding and robotic systems.
Features
Bottleneck profile for access to restricted spaces and tight joints
High-conductivity hard-drawn copper construction for thermal and electrical conductivity
Internal self-insulating fiberglass insulator to prevent accidental arcing between nozzle and gas diffuser
Precision-machined smooth surface finish with rounded edges to minimize spatter build-up
Dual Taper Technology for secure locking to the gooseneck to prevent loosening from vibration
Engineered for high-amperage pulse welding where heat peaks are elevated
Designed to reduce arc erosion and extend service life compared to standard copper alternatives
