The Tregaskiss 401-7-87 is a heavy-duty, air-cooled slip-on MIG welding nozzle belonging to the TOUGH LOCK™ Consumable Series. It is constructed with a brass outer shell and a brass internal insert, designed for high-heat environments and robotic welding systems requiring consistent electrical isolation and thermal management.
Features
TOUGH LOCK™ system maximizes surface area contact between nozzle and retaining head for heat dissipation
Internal brass insert maintains inner diameter and prevents nozzle rocking on the gas diffuser
High-temperature fiberglass insulator provides electrical isolation from the gas diffuser to prevent accidental arcing
Heavy-duty crimp assembly secures the brass outer shell, insulator, and internal insert as a single unit
Vibration-resistant locking mechanism prevents consumables from loosening during high-frequency robotic movement
Smooth surface finish and rounded edges designed to minimize weld spatter accumulation
Simplified maintenance allows contact tip replacement while the retaining head remains locked to the gooseneck
