0810123881 - ESAB A2 SAW Feed Roll and Contact Kit 3.0mm

Keep Your A2 Tractor Running Smoothly

If you are running an ESAB A2 Multitrac or a beam-mounted A2 head, you know that the secret to a perfect submerged arc weld lies in the consistency of the wire feed. When you are pushing 3.0mm (0.12") wire all day, your feed rolls and contact jaws take a beating. The heavy wire requires significant torque to move, and any wear on the drive rolls can cause slippage. That slippage leads to a stuttering arc, inconsistent pile-up, and potential defects that require expensive gouging and rework. The ESAB 0810123881 Wear Part Kit is your solution to getting that smooth, reliable feed back into your operation.

This kit is specifically put together for running 3.0mm wire. It takes the guesswork out of swapping setups or performing maintenance. Instead of digging through a bin of mixed parts trying to find a matching set of rollers and the right size contact jaw, you grab this box and you have everything you need. The kit typically includes the drive rolls that grip the wire, the pressure rolls that keep it in line, and the contact elements that transfer the massive welding current into the wire. Because these are genuine ESAB parts, they fit the A2 head perfectly—no filing, no shimming, just bolt on and go.

Changing out your wear parts is also the best time to inspect the rest of your feed unit. When you install this kit, you ensure that the wire is centered and that the pressure is applied evenly. This is crucial for 3.0mm wire, which is stiff and unforgiving if the alignment is off. Fresh contact surfaces mean better electrical conductivity, which stabilizes your arc voltage and helps the flux cover form properly. Whether you are welding bridge girders, wind tower sections, or heavy pipe, you need your machine to perform predictably.

Don't wait until the wire starts slipping mid-weld to think about your drive system. Keeping a 0810123881 kit on the shelf or in your toolbox means you are ready for a quick changeover or an emergency repair. It’s about minimizing the downtime of your tractor and maximizing arc-on time. With fresh rollers and tips, you can trust your settings again, knowing that the wire speed you see on the PEK or A2-A6 controller is exactly what is being delivered to the puddle. Keep your beads uniform and your operation efficient with this dedicated 3.0mm setup kit.
