12401886 - Tweco Velocity VNH75C Heavy Duty MIG Nozzle, 3/4" Bore, 1/8" Recess (2-Pack)

Heavy Duty Performance with Tweco Velocity VNH75C

If you are running a Tweco Fusion gun or have upgraded your trusty Spray Master to the Velocity system, you know that not all nozzles are created equal. The Tweco VNH75C (1240-1886) is the heavy hitter of the lineup. With a massive 3/4-inch bore, this nozzle is built for when you need to crank up the amps and lay down serious metal. Whether you are running hot spray transfer on heavy plate or pushing dual-shield flux core, that extra width gives you the gas coverage you need to keep porosity out of your welds. The copper construction pulls heat away fast, keeping the front end of your gun cooler even when you're pushing the duty cycle to the limit.

One of the biggest headaches in MIG welding is dealing with threaded nozzles that seize up after a long shift. You grab your pliers, crank on it, and end up damaging the diffuser or the nozzle itself. The Velocity system solves that completely. The VNH75C uses a threadless, drop-in design. It slides right on and locks into place, and when it's time to clean out spatter or change a tip, it slides right off. No threads to cross, no threads to seize. It’s a game-changer for daily maintenance.

This specific model features a 1/8-inch recess. That little bit of setback is crucial—it keeps your contact tip out of the puddle and protects it from direct spatter hits, which means you aren't changing tips every hour. It also helps funnel that shielding gas right where you need it. This pack comes with two nozzles, so you've always got a spare in your toolbox when things get rough. If you are doing heavy fabrication, structural steel, or equipment repair, the VNH75C is the nozzle you want on the end of your torch.
