0460101880 - ESAB Right Side Feed Wheel for PKB 250/400 Wire Feeders

Restore Precision Wire Feeding with the ESAB PKB Feed Wheel

As a professional welder, you know that the consistency of your wire feed is directly related to the quality of your arc. If you are operating a MIG welder equipped with an ESAB PKB 250 or PKB 400 wire feed mechanism, you rely on the drive system to deliver wire smoothly at the exact speed you set. When the feed wheel begins to wear out, you might experience erratic feeding, wire slippage, or inconsistent arc length, all of which can lead to frustrating defects like porosity or burn-back. The ESAB Feed Wheel Right (0460101880) is the specific replacement part you need to address these mechanical issues and get your machine running like new again.

This feed wheel is located on the right side of the drive assembly. In the PKB system, the feed wheels are the primary contact points that grip the wire (often in conjunction with pressure rolls) to push it through the liner and out the contact tip. Over thousands of hours of welding, the friction from the wire—especially hard wires like mild steel or stainless—can wear down the traction surface or the gear teeth of the wheel. Once this wear occurs, tightening the tensioner won't solve the problem; it will only deform the wire. The only true fix is to replace the worn wheel with this genuine ESAB part. Installing the 0460101880 is a straightforward maintenance task that can usually be accomplished with standard hand tools, allowing you to get back to welding quickly.

Why choose the genuine ESAB part? Because the tolerances in wire feeding are incredibly tight. A feed wheel that is slightly off-spec can cause the wire to wander or vibrate, affecting your bead profile. This OEM wheel is machined to perfectly match the gearing and spacing of the PKB 250 and 400 mechanisms. It ensures that the grip on the wire is firm without being crushing, preserving the roundness of the wire for better electrical contact at the tip. This is particularly important when working on critical code welds where every variable must be controlled.

Don't let a worn $50 part ruin a $5000 job. If you notice your wire feeder struggling, or if you hear the motor turning but the wire hesitating, check your drive rolls and feed wheels. If the right-side wheel shows signs of smoothing or damaged teeth, swap it out with this authentic ESAB replacement. It is designed to withstand the rigors of industrial environments, providing reliable traction for both solid and flux-cored wires. Keep your arc smooth and your frustration low by maintaining your drive system with the correct components.
