- Self-insulated design reduces spatter adhesion
- Heavy-duty rating withstands high-amperage MIG
- Fits 404-26 and 404-32 diffusers
Slip-On Nozzle 1/2" Tapered
The TREGASKISS 401-4-50 is a copper welding nozzle built for MIG (GMAW) processes. Its tapered bore measures 1/2 inch and uses a slip-on connection. The tip sits at a 1/8 inch recess inside the nozzle. It is rated for heavy-duty use in automotive, fabrication and manufacturing environments.
Fits TOUGH LOCK and Compatible Guns
This nozzle fits TOUGH LOCK series guns and BTB, Clean Air, G1 Water-Cooled, G2, Robotic CA3, S-Gun, T-Gun Water-Cooled, TA3, TGX and ThruArm G2 models. It requires gas diffuser 404-26 or 404-32 for installation. The self-insulated copper body removes the need for separate insulation parts.
Heavy-Duty Copper for Standard Bore
The 1/2 inch bore handles typical MIG welding gas flow and spatter in heavy-duty applications. Copper construction resists heat and wear during extended runs. It is not suited for jobs needing a larger or smaller bore diameter, a different tip recess or a thread-on connection type.

Questions about this item
How long can the 1/2" bore handle continuous MIG welding before spatter blocks the gas flow?
The self-insulated copper bore resists spatter build-up during extended MIG runs, and the 1/8" tip recess keeps the contact tip shielded so gas coverage stays consistent.
Does the nozzle itself get hot or draw power during all-day fabrication work?
The copper body conducts heat away from the weld zone while the self-insulated design limits thermal transfer to the diffuser, so the nozzle stays cooler without any electrical draw.
Which gas diffuser must I already have for this slip-on nozzle to fit?
It fits directly onto diffuser numbers 404-26 or 404-32, so one of those must be on the gun before the nozzle will seat.
