When the job calls for serious welding power and you need equipment that won't quit, the Tweco Classic No. 4 MIG Gun is the tool you reach for. Known simply as the "Number 4" in shops across the country, this gun is the definition of an industry workhorse. With a 400-amp rating, it handles high-deposition welding with ease, allowing you to lay down heavy beads on thick plate without overheating the torch. This version comes with a massive 25-foot cable, giving you the freedom to move around large workpieces without dragging your feeder with you.
Built for the Real World
Welding environments are tough—sparks, heat, drops, and drags are part of the daily grind. The Tweco Classic 4 is built to take it. From its impact-resistant handle to the metal-jacketed conductor tube, every component is engineered for longevity. The air-cooled design means you don't have to worry about water coolers or leaking hoses; just plug it in and weld. The trigger action is crisp and reliable, and the handle shape provides a comfortable grip that helps you maintain control and precision, even when wearing heavy welding gloves.
Easy to Maintain, Easy to Love
One of the best things about the Tweco Classic series is how easy it is to find parts. You probably already have the consumables in your toolbox. It uses the standard tips, nozzles, and diffusers that are stocked in almost every welding supply shop. If you ever need to replace a liner or a trigger, the gun is designed to be field-repairable, so you can get back to burning wire quickly. The 25-foot lead is perfect for working on trailers, truck bodies, or structural beams where you need that extra length to get the job done right.
