0671126081 - ESAB PKB 250/400 Push-Pull Gun Feed Drive Assembly

Smooth Feeding for Flawless Aluminum Welds

Every welder knows the frustration of a push-pull gun that just won't feed right. You're in the middle of a long bead on an aluminum trailer or boat hull, and suddenly the wire stutters. The arc sputters, and you're left with a mess to grind out. Often, the culprit isn't the machine or the liner—it's the feed mechanism inside the gun handle. The ESAB 0671126081 Feed Mechanism is the direct replacement for your PKB 250 or PKB 400 torch, designed to get you back to laying down smooth, consistent beads.

Push-pull guns are essential for feeding soft aluminum wire over long distances, but they rely heavily on the small drive assembly in the handle to pull the wire that last few feet. When the gears or rollers in this mechanism wear out, you lose that positive grip. This replacement unit restores that "like-new" feeling to your torch. It grabs the wire firmly but gently, ensuring it feeds at the exact speed set by your machine. This means better arc starts, fewer burn-backs, and a much more enjoyable welding experience.

Don't struggle with equipment that fights you. If you've noticed your PKB gun slipping or making grinding noises, it's time to swap out the feed mechanism. This part is a genuine ESAB component, so you know it will fit your torch perfectly. It's built to handle the heat and the dust of the shop, giving you reliable performance shift after shift. Keeping your equipment in top shape is the secret to professional-looking welds and less frustration at the end of the day.

Whether you are fabricating custom aluminum parts or doing heavy repair work, your tools are your livelihood. This feed mechanism ensures that your high-performance PKB torch operates exactly as it was designed to. Swap it out, thread up your spool, and get back to welding with confidence, knowing your wire feed is locked in and steady.
