10311643 - Tweco SEFC350 350A Flux Core MIG Gun, 15ft Cable, Tweco Connection

Built for the Grind: Tweco SEFC350

When you're burning heavy flux-cored wire, you need a gun that can take the heat and keep on feeding. The Tweco SEFC350 is that gun. Rated for a solid 350 Amps, this torch is designed for the welder who spends their day on structural steel, heavy equipment repair, or in the shipyard. It’s not just a plastic toy; it’s a tool built to survive the drop, the drag, and the spatter of the job site.

The 15-foot cable gives you plenty of room to move around your workpiece without constantly dragging the feeder with you. We know that a stiff, heavy cable can wreck your wrist by the end of a shift, so Tweco designed this assembly to balance durability with flexibility. The handle is shaped to fit comfortably in your glove, giving you good trigger control whether you're welding flat, horizontal, or overhead.

One of the best things about this gun is that it uses standard Tweco consumables. You won't be stuck waiting for some proprietary contact tip to ship from overseas. You can grab what you need from the crib or the local supply shop and get back under the hood. The Tweco back-end connection means it plugs right into most standard feeders, so you can swap it out and get to work in seconds.

Why Welders Like It:

• High Heat Capacity: Runs 350A all day without melting down.
• Tough Cable: 15 feet of reach that resists cuts and burns.
• Easy Parts: Uses the tips and parts you already know and trust.
• Solid Grip: Comfortable handle for long arc-on times.

Stop fighting with undersized guns that overheat halfway through a pass. Upgrade to the Tweco SEFC350 and experience the difference a dedicated flux-core gun makes.
