When it comes to heavy-duty MIG welding, few tools are as trusted as the Tweco No. 4 MIG Gun. This 15-foot torch is built to handle the heat, rated for 400 Amps, making it the go-to choice for fabricators pushing high wire speeds and thick materials. If you are running a Miller wire feeder and need a gun that can take a beating and keep on welding, this Tweco Classic series gun is the upgrade you’ve been looking for. It combines the proven performance of the Tweco design with a direct Miller plug, so you can hook it up and start welding immediately.
The "No. 4" is famous for its simplicity and toughness. It features a heavy-duty coaxial cable that stands up to the rigors of the shop floor—drag it over steel, around corners, and through grime; it’s built to last. The handle is shaped to provide a secure grip, and the trigger action is crisp and reliable, designed to withstand thousands of cycles. One of the biggest advantages of running a Tweco gun is the consumables. You can find Tweco 14-series tips and 24-series nozzles almost anywhere, and they are cost-effective, keeping your running costs down over time.
Versatility is key in professional welding. The conductor tube on this gun can be rotated 360 degrees, giving you the flexibility to weld in out-of-position scenarios or tight corners without straining your wrist. The 15-foot length offers a great balance between reach and wire feed reliability. Whether you are welding mild steel, stainless, or flux-cored wires, the Tweco No. 4 provides the consistent electrical conductivity and gas coverage needed for X-ray quality welds. Don't settle for flimsy torches; equip your Miller machine with the industry standard for durability.
