30401107 - Tweco TAM Series 400A MIG Gun, 15ft, .035-.045 Wire

Built for the Grind: Tweco 400 Amp MIG Gun

When you are burning wire all day, you need a gun that can take the heat and keep feeding smoothly. The Tweco TAM Series 415-3545 is a 400-amp beast designed for welders who demand reliability. This isn't a hobbyist torch; it's an industrial tool built to handle high-amperage spray transfer and heavy flux-cored applications without overheating in your hand. If you are pushing .035 or .045 wire on structural steel or heavy equipment repairs, this gun is ready for the task.

The 15-foot lead gives you the freedom to move. We all know the frustration of being just a foot short of the joint; with this gun, you have the reach to work around large assemblies, trailers, or frames without constantly dragging your feeder around the shop floor. The cable itself is flexible yet tough, resisting kinks and abrasion from dragging over concrete and steel edges. The strain relief systems at both the gun handle and the backend connection are designed to prevent cable pull-out, a common failure point in lesser guns.

Comfort is king during a long shift. The handle is ergonomically shaped to fit naturally in a gloved hand, reducing grip fatigue and wrist strain. The trigger action is crisp and responsive, designed to last through thousands of cycles. Because it uses standard Tweco consumables, you probably already have the tips and nozzles you need in your toolbox. You won't have to hunt for proprietary parts when you burn a tip back.

This gun features a standard Tweco connection, meaning it plugs right into most major wire feeders equipped with a Tweco adapter. It's air-cooled, so there are no water lines to leak or coolers to maintain—just plug it in, trim your wire, and start laying beads. For welders who value uptime, durability, and a solid feel in the hand, the Tweco TAM Series 415-3545 is a solid investment in your daily productivity.
