2-2592 - Tweco PWM-4A 400 Amp MIG Gun, 25ft Cable, Offset Handle

Maximize Your Reach and Power

As a professional welder, you know that dragging your wire feeder around the shop floor is a hassle that kills your momentum. The Tweco PWM-4A MIG Gun solves this problem with a massive 25-foot cable, giving you the freedom to move around large assemblies without being tethered on a short leash. Whether you are welding on a trailer chassis, a large tank, or structural columns, this gun gives you the reach you need to get the job done efficiently.

Power is nothing without control and comfort. This 400-amp beast is designed to run hot and heavy, handling flux-cored and solid wires for thick plate welding without overheating. Despite its heavy-duty capacity, the offset handle design is all about your comfort. It aligns your wrist and arm in a more natural position, reducing the strain that leads to fatigue at the end of a long shift. A comfortable welder is a steady welder, and this gun helps you lay down consistent, high-quality beads hour after hour.

Reliability is key when the hood is down. The Tweco PWM-4A is built tough to survive the drops, drags, and sparks of a real welding shop. It uses the classic Tweco consumables you already know and trust, so finding a replacement tip or nozzle is never a headache. The air-cooled design keeps things simple—no water lines to leak or coolers to maintain—just plug into your feeder's Tweco-style connection and start burning wire. Upgrade your setup with a gun that works as hard as you do.
