251922 - Miller .030-.035 Aluminum U-Groove Drive Roll

Smooth Aluminum Feeding with Miller

If you are planning to weld aluminum with your Millermatic or Multimatic machine, swapping out your standard drive rolls is the first step towards success. The Miller 251922 Drive Roll is designed to take the headache out of feeding aluminum wire. We all know that aluminum is soft and prone to kinking, crushing, or shaving if you try to force it through a system meant for steel. That is where this U-Groove roll saves the day. Its smooth, rounded channel cradles the wire, pushing it gently but firmly towards the torch without flattening it out.

One of the biggest advantages of this specific roll is its polished finish. Standard knurled or rough rolls will chew up aluminum, creating tiny metal shavings that pile up in your liner and eventually jam your gun. This polished U-groove roll glides against the wire, keeping it clean and round. This means you get a steady, uninterrupted flow of wire at the arc, which is absolutely essential for laying down those stack-of-dimes aluminum beads. No more sputtering, no more burn-backs caused by feed issues.

This roll is a two-in-one value, featuring grooves for both .030 and .035 wire sizes. Whether you are working on thin sheet metal or slightly thicker brackets, you can switch between wire sizes easily. It is a genuine Miller part, so you know it will fit your machine perfectly and last for the long haul. Don't let poor wire feeding ruin your aluminum projects; equip your welder with the right drive roll and experience the difference in performance.
