OVERVIEW

The Legend in Your Hand: Tweco Classic No. 4

If you've been welding for any length of time, you know the Tweco Classic No. 4. It's the gun that built the industry. This isn't a flimsy hobbyist torch; this is a 400-amp workhorse designed for welders who burn wire all day, every day. With SKU 10401930, you get the reliability of the Classic 4 paired with a 15-foot cable and a Lincoln-style connection, making it the perfect upgrade or replacement for your Lincoln wire feeder.

Built for the Grind
The Classic No. 4 is famous for its toughness. The handle is impact-resistant, and the cable is armored against the hot sparks, sharp metal edges, and heavy equipment typical of a fab shop. The 15-foot length gives you the freedom to move around your workpiece without getting hung up. It's rated for 400 amps, so you can crank up the heat for thick plate welding without worrying about the gun overheating in your hand.

Easy Consumable Changes
One of the best things about running a Tweco is that parts are everywhere. This gun uses the standard consumables you likely already have in your toolbox: 14 Series tips and 24 Series nozzles. No hunting for proprietary parts when you're in the middle of a rush job. The gun comes ready to run .035" to .045" wire right out of the box, so you can hook it up and start laying beads immediately.

Comfort and Control
Despite its heavy-duty rating, the Classic 4 is balanced to reduce wrist strain during long welds. The trigger action is crisp and reliable, giving you precise control over your arc starts and stops. If you are looking for a gun that feels right and welds right, stick with the classic.
