OVERVIEW

The Legend of the Shop Floor: Tweco Spray Master 350

If you've spent any time burning wire in a heavy fab shop, you know the Tweco Spray Master. It’s the gun that doesn't quit. This MS350 model (1036-1726) is built for the welder who needs to push 350 amps all day long without their hand feeling like it's in a toaster. With a 15-foot lead, you have the freedom to move around large weldments, and the Miller-style plug means you can hook it straight up to your blue feeder and get to work immediately.

This beast comes ready to run 1/16" (1.6mm) wire right out of the package. Whether you are running dual-shield flux core or laying down heavy spray transfer welds on thick plate, the Spray Master handles the heat. The ergonomic handle is designed to fit naturally in your glove, reducing wrist strain during those long passes. One of the best features is the Eliminator front-end. It simplifies your consumable stack-up, meaning fewer parts to lose and a more consistent arc. The gas coverage is superior, helping you keep porosity out of your welds.

We know that in the real world, equipment gets dragged, dropped, and stepped on. That’s why the Spray Master uses a tough composite handle and a heavy-duty strain relief system. The trigger is responsive but durable, designed to last through hundreds of thousands of cycles. If you are tired of flimsy guns that overheat or jam up when you're trying to meet a deadline, upgrade to the Tweco Spray Master MS350. It’s the tool that respects your skill and keeps up with your pace.
