CM415-3545 - Tweco Style 400A MIG Gun, 15ft Cable, Miller Connection

Reliable Power and Comfort in Your Hand

Step up your welding game with this 400 Amp Tweco-style MIG gun, specifically tailored for your Miller welding machine. If you are looking for a torch that can handle the heat of heavy fabrication while keeping your consumables budget in check, this is the tool for you. The 15-foot lead gives you the freedom to move around your workpiece, making it ideal for welding on trailers, truck beds, or large structural frames where a shorter cable just won't cut it.

Comfort is key during long arc-on times, and this gun features an ergonomically contoured handle that fits naturally in the hand, reducing grip fatigue and wrist strain. The trigger action is smooth and responsive, giving you precise control over your starts and stops. Because it uses the classic Tweco #4 style front-end parts, you likely already have the tips and nozzles you need in your toolbox. There is no need to hunt for proprietary or expensive consumables; simply grab standard 14-series tips and get back to burning wire.

Installation is a breeze thanks to the Miller-style back-end plug. It slides right into the receptacle of most Miller feeders and locks securely, ensuring a solid electrical connection and leak-free gas flow. The heavy-duty cable is flexible yet tough, resisting cuts and abrasion from shop environments. Whether you are running .035" wire for general assembly or .045" for deeper penetration on thicker plate, this gun feeds smoothly and arcs stable, helping you lay down high-quality beads shift after shift.
