10401928 - Tweco Classic No. 4 MIG Gun, 400A, 12 ft, Lincoln Connection

The Legend is Back: Tweco Classic No. 4

If you have been welding for any length of time, you know the Tweco Classic No. 4. It is the gun that built the industry. This isn't just a tool; it's a reliable partner that doesn't quit when the heat is on. This version (1040-1928) combines that legendary Tweco toughness with a direct Lincoln rear connection, so you can hook it up to your Lincoln feeder and get straight to work. No adapters, no hassle—just pure welding power.

Built for the Real World
The first thing you'll notice is the handle. The classic oval shape fits naturally in your hand, giving you the control you need for precise bead placement without cramping up your wrist halfway through the shift. The paddle switch is responsive and durable, designed to survive thousands of cycles. Whether you are welding structural beams, heavy equipment, or general fabrication, the 400-amp rating means this gun can take the heat. The 12-foot cable gives you enough room to move around your workpiece without getting tangled in excess slack.

Easy Maintenance, Less Downtime
We know that time spent fixing your gun is time you aren't burning wire. The Tweco Classic 4 uses standard consumables that you can find almost anywhere. Swapping out a contact tip or a nozzle takes seconds. The heavy-duty metal jacket on the neck stands up to abuse, and if you ever do manage to damage the cable, the whole thing is serviceable. It is built to be dragged across concrete floors, stepped on, and worked hard day in and day out.

Why Welders Choose the Classic 4:

• Proven Reliability: It works when you need it to.
• Comfort: The handle design reduces fatigue.
• Power: 400 Amps of air-cooled performance.
• Compatibility: Plug-and-play with your Lincoln machine.
