12101346 - Tweco WS21-50F WeldSkill MIG Nozzle, 1/2" Bore, Flush Tip, 2-Pack

Keep Your WeldSkill Gun Running Smoothly

Every welder knows that a clogged or damaged nozzle can ruin a perfect bead. The Tweco WeldSkill WS21-50F MIG Nozzle is the genuine replacement part you need to keep your arc stable and your welds clean. Designed for the popular WeldSkill series guns, this nozzle features a 1/2-inch bore that provides excellent gas coverage for most standard welding applications, from auto body repair to light structural fabrication. If you are tired of struggling with porosity caused by poor gas flow, swapping out your old, battered nozzle for a fresh WS21-50F is often the quickest fix.

Why Choose the Flush Tip Design?
This nozzle features a "Flush" tip relationship, meaning your contact tip sits even with the end of the nozzle. This is a favorite setup for many operators because it lets you get closer to the work surface without losing sight of the puddle. It’s particularly forgiving for newer welders or those working in positions where visibility is key. The slip-on design means no threads to cross or seize up with spatter—just twist, pull, and replace.

Value and Reliability
Sold in a convenient pack of two, this set ensures you aren't left high and dry in the middle of a project. Tweco's copper construction is tough enough to handle the heat, and with a little nozzle dip, these nozzles clean up easily. Whether you are running a Tweco WeldSkill 140, 180, or a larger unit using the 21-series front end, these nozzles deliver the consistent performance the brand is known for. Don't let a $10 part cause a $100 problem—keep your torch tip-top with genuine Tweco consumables.
