The XTRWELD 401-6-50 is a heavy-duty MIG nozzle designed for Tregaskiss-style MIG gun applications. With a 1/2-inch diameter and a 1/8-inch recess, this nozzle delivers consistent shielding gas coverage and is built to handle the demands of continuous production welding. It is marked with the part number or size directly on the nozzle body, making identification fast during consumable changeovers. Licensed welding technicians and fabrication shop professionals install this type of consumable as part of routine MIG gun maintenance.
This nozzle is intended for use with Tregaskiss Tough Gun and Bernard BTB TGX guns. It is manufactured to OEM-quality standards and is interchangeable with Tregaskiss traditional consumables. Note that Tregaskiss-style traditional consumables can be used as full replacements for Tregaskiss Toughlock, AccuLock, and R-series consumables, though these series are not intended to be mixed within the same setup. Brand names referenced are for compatibility identification purposes only.
Designed for use with Tregaskiss Tough Gun and Bernard BTB TGX MIG guns. Functions as a full replacement for Tregaskiss Toughlock, AccuLock, and R-series consumables when used as a complete system swap. Not intended to be mixed with those series in a hybrid configuration.
MIG nozzles are installed and replaced by qualified welders or welding maintenance technicians. Always power down the welder and allow the gun body to cool before removing or installing nozzle consumables. Ensure the contact tip and gas diffuser are also inspected during nozzle replacement to maintain optimal shielding gas flow. Do not overtighten threaded nozzles, as deformation can affect gas coverage and arc stability.
