10471016 - Tweco WeldSkill 400A MIG Gun, 25ft, Tweco Connection

Get the Reach You Need with the Tweco WeldSkill 400

If you are burning heavy wire and need a gun that can keep up, the Tweco WeldSkill 400 Amp MIG Gun is your answer. This isn't just another torch; it's a tool built on the legacy of Tweco, the brand that practically invented the modern MIG gun. With a 400-amp rating, this beast is ready to lay down serious beads on thick plate, structural beams, and heavy machinery. Whether you are running solid wire with mixed gas or pushing flux-cored wire through for deep penetration, this gun delivers the current stability you need for a smooth, consistent arc.

The 25-foot lead is a game-changer for shop layout. Stop dragging your heavy welder across the floor every time you need to reach the other side of a trailer or a large frame. The 25-foot cable gives you the freedom to move, climb, and position yourself for the perfect weld angle without the leash holding you back. The cable is tough, too—built to withstand being stepped on, dragged over concrete, and exposed to sparks and spatter.

Maintenance is a breeze because this gun uses the consumables you probably already have in your toolbox. It takes standard Tweco tips, nozzles, and diffusers—the stuff you can find at any welding supply shop. No hunting for proprietary, expensive parts. The metal-jacketed gooseneck is tough enough to use as a chipping hammer (though we don't recommend it!) and swivels to help you get into tight corners. The handle feels right in your hand, with a trigger that's responsive but not too sensitive, preventing accidental arcs.

Connecting it up is simple if your machine runs a Tweco-style plug. Just plug it in, tighten it down, and you are ready to weld. The strain relief systems are beefy, protecting the copper strands and the liner from getting crushed or kinked at the connection points. If you want a no-nonsense, high-power MIG gun that won't let you down when the heat is on, the Tweco WeldSkill 400 is the upgrade your rig deserves.
