OVERVIEW

Experience the Legend: Tweco Spray Master 350

When the heat is on, you need a MIG gun that stays cool. The Tweco Spray Master MS315 (350 Amp) is legendary in the welding industry for a reason: it was specifically built to handle the intense heat of spray transfer welding without becoming too hot to hold. If you are pushing high amps all day, this is the gun that will keep you comfortable and welding longer. This model (1036-1640) comes ready to rock with a 15-foot cable and a direct Miller connection, so you can plug it straight into your blue machine and get to work.

Built for Comfort and Durability
The ergonomic handle of the Spray Master fits naturally in the hand, reducing fatigue during long welds. But comfort isn't just about the grip; it's about temperature. Tweco's unique design dissipates heat away from the handle faster than standard guns, meaning you don't have to stop just because your glove is getting too hot. The 15-foot lead gives you plenty of room to move around large weldments without constantly dragging the feeder.

Ready for Heavy Metal
Out of the box, this gun is set up for 1/16" (1.6mm) wire, making it a beast for heavy structural welding, shipbuilding, and equipment manufacturing. It uses the classic Tweco consumables you likely already have in your shop—tough, affordable, and easy to change. Whether you are running flux-cored or solid wire in spray mode, the Spray Master 350 delivers consistent wire feeding and a stable arc. Don't settle for a generic replacement; equip your rig with the gun that defined heavy-duty air-cooled performance.
