OVERVIEW

Reliable Power and Comfort for Heavy Welding

Step up your welding game with the Tweco WeldSkill 400 MIG Gun, a tool built for welders who need consistent power delivery without sacrificing comfort. If you are pushing 0.045" or 1/16" wire all day, you need a gun that stays cool and handles the heat. This 400-amp air-cooled torch is designed to do just that, offering a 60% duty cycle that keeps you welding longer without overheating the handle or the cable.

The ergonomic handle design is shaped to fit naturally in your hand, reducing grip fatigue during long beads. The trigger action is smooth and positive, giving you precise control over arc starts and stops. With a 12-foot lead, you have plenty of room to move around your workpiece without dealing with the feeding issues sometimes associated with longer 15-foot or 25-foot guns. The ball-and-socket cable connection at the handle improves flexibility, allowing you to manipulate the gun into tight corners and difficult positions with ease.

One of the best features for any welder is simplicity. This gun uses the classic Tweco consumables you likely already have in your toolbox. Changing a tip or cleaning a nozzle is quick and frustration-free. The nozzle design is slip-on for easy removal, and the gas diffuser ensures smooth shielding gas coverage to prevent porosity. Whether you are repairing heavy machinery, fabricating structural beams, or working in a production line, the WeldSkill 400 is a dependable partner that won't let you down.
