If you are pushing high amperages and laying down serious metal, you need a gun that stays cool and comfortable. This model (SKU: 1036-1725) delivers 350 Amps of power and comes with a 15-foot cable, giving you the freedom to move around your workpiece without constantly repositioning your feeder. It is the go-to tool for welders who refuse to compromise on quality or comfort.

Ready for Heavy Work

Designed for the pros, this gun arrives pre-configured for 1/16" (1.6mm) wire, perfect for those heavy-duty jobs where deposition rate is king. Whether you are welding structural beams, repairing heavy machinery, or fabricating thick plate, the Spray Master MS350 ensures a stable, smooth arc. Its ability to handle the heat of spray transfer mode means you can weld longer without the gun overheating, keeping you productive and your welds consistent.

Built for the Welder

Tweco understands that a heavy gun leads to fatigue, which causes mistakes. That’s why the Spray Master features a superbly balanced, ergonomic handle that reduces wrist strain. The Tweco-style rear connection makes setup a breeze—just plug it into any compatible feeder and you are ready to weld. Plus, with the famous 360-degree rotatable neck, you can easily reach into tight corners or awkward angles without fighting the cable.
