CX420-3545 - 400A Tweco Style MIG Gun with 20ft Cable and Euro Connector

Get the Reach You Need with 400 Amps of Power

Tired of dragging your welder around the shop just to reach the other side of a trailer? The CX420-3545 MIG Gun is your solution. With a massive 20-foot cable, this torch gives you the freedom to weld where you need to, not just where your machine sits. It’s built for the professional welder who pushes 400 amps and needs equipment that won't melt down halfway through a shift.

Built Tough for the Grind

This isn't a hobbyist toy. The CX420-3545 is a Tweco #4 style gun, meaning it's designed for heavy-duty structural work, fabrication, and repairs. The handle is ergonomically contoured to fit comfortably in your hand, reducing grip fatigue during those long beads. The cable itself is reinforced to resist kinking and crushing, so stepping on it or dragging it over sharp edges won't kill your wire feed. It’s air-cooled, keeping things simple without the hassle of water lines, yet robust enough to handle high heat.

Easy Parts, Easy Life

We know that hunting for specialized contact tips is a pain. That's why this gun uses standard Tweco-style consumables. You can grab tips, nozzles, and diffusers from almost anywhere. Whether you are running .035 hard wire or .045 flux core, this gun feeds smoothly and arcs hard. The Euro backend makes swapping guns a breeze—just unplug your old one and twist this one in. It’s the perfect backup or primary gun for any machine with a Euro port.
