2-2845 - Thermal Arc PWM-300 MIG Gun 300A 12.5ft

Reliable Performance for All-Day Welding

If your current MIG gun is overheating, stuttering, or just falling apart, the Thermal Arc PWM-300 is the heavy-hitter you need to get back to laying smooth beads. Rated at a solid 300 Amps, this gun doesn't back down from high-voltage spray transfer or long flux-cored runs. The 12.5-foot cable gives you the freedom to move around your workpiece without getting tangled, while still keeping the wire feed path short enough to prevent bird-nesting and drag.

Comfort is key when you're under the hood for hours. The PWM-300 features a handle design that sits naturally in your grip, reducing wrist strain and making it easier to manipulate the torch angle for vertical and overhead welds. The trigger is crisp and reliable, so you aren't fighting the gun to keep the arc lit. Plus, because it uses standard Tweco-style parts, you can grab replacement tips and nozzles at almost any welding supply shop—no hunting for obscure proprietary consumables.

Whether you are repairing heavy equipment, fabricating structural frames, or working in a production line, this gun delivers the consistency you expect from a professional tool. It's built tough to withstand the sparks, spatter, and rough handling of a real shop environment. Upgrade your setup with a gun that matches the power of your machine.
