The Legend Returns: Tweco Classic 4 with Euro Connect

If you've been in the welding game for any length of time, you know the Tweco #4. It's the gun that built the industry. Rugged, reliable, and simple to maintain, it's the torch you grab when there's serious work to be done. This model, the 1040-1613, brings that legendary toughness to machines with a Euro-style connection. No more hunting for adapters—plug this 15-foot beast directly into your Fronius, ESAB, or Euro-equipped Miller/Lincoln feeder and get to work.

This gun is set up right out of the box for 1/16" (1.6mm) wire, perfect for those heavy flux-core jobs or high-deposition solid wire applications. With a 400 Amp rating, you can push it hard without overheating. The air-cooled design keeps things simple—no water lines to leak or coolers to fail. You get the classic oval handle that fits naturally in your hand and the responsive paddle trigger that gives you positive feedback every time you strike an arc.

Maintenance is a breeze because it uses the standard consumables you likely already have in your toolbox. The metal-jacketed conductor tube and heavy-duty cable strain relief mean this gun can take a beating—dropped on concrete, dragged over steel, or stepped on—and keep feeding wire smoothly. When your welds need to pass X-ray and your deadlines are tight, trust the gun that has proven itself for generations. Upgrade your setup with the Tweco Classic No.4.
