The Legend of Cool: Tweco Spray Master 350

If you have ever had a MIG gun get so hot you had to put it down, you haven't welded with a Tweco Spray Master. The MS315 configuration brings the legendary cooling capabilities of the Spray Master line to your Lincoln Electric machine. This isn't just another replacement gun; it's an upgrade to your entire welding experience. Rated for a true 350 Amps, this gun is built for welders who burn hot and fast, utilizing spray transfer modes that would melt lesser torches. The secret lies in the heavy-duty conductor tube and efficient air-cooling design that pulls heat away from your hand and the consumables.

This model comes ready to tackle the big jobs. With a 15-foot lead, you have the freedom to move around your workpiece without feeling tethered to the machine. It is set up right out of the box for 1/16" (1.6mm) wire, making it a beast for heavy structural flux-core or high-deposition solid wire welding. The Lincoln-style rear connection means you can plug it directly into your compatible Lincoln feeder—no guessing, no adapters, just a solid electrical connection that ensures smooth arc starts and stable feeding.

Comfort is just as important as power. The Spray Master features an ergonomic handle that fits naturally in the hand, reducing grip fatigue over long shifts. The trigger action is crisp and reliable, designed to last for hundreds of thousands of cycles. When it comes time to swap out a tip or clean the nozzle, you are using standard Tweco consumables—parts you can find in almost any weld shop in the world. Whether you are building trailers, repairing heavy machinery, or fabricating structural steel, the Tweco Spray Master MS315 is the reliable partner you need to lay down perfect beads shift after shift.
