This drive roller for Lincoln Pro MIG welders is a dual-groove replacement roll. The listing names the Pro MIG 135, Pro MIG 140 (code 11128 only) and Pro MIG 175, with one groove for .023-.025 inch wire and one for .030-.035 inch wire. It is worth considering if your feed roll is worn and the wire slips or feeds unevenly. Confirm your welder model and code before ordering, because fit depends on both. This review is based on the Amazon listing, not hands-on testing.

- Open the wire feed compartment and release the tension arm.
- Remove the old roller using the retaining screw or knob shown in your manual.
- Fit the new roller with the groove for your wire size in line with the wire path.
- Close the arm, set tension lightly and feed a short length of wire to test.

Frequently Asked Questions
Does this drive roller fit welders other than the Lincoln Pro MIG models?
The listing names the Pro MIG 135, Pro MIG 140 (code 11128 only) and Pro MIG 175. Do not assume it fits other brands or other Lincoln models. Check your welder model and code, and compare the roller with the one you are removing.
Which wire sizes does it support?
One groove is listed for .023-.025 inch solid wire and the other for .030-.035 inch solid or flux-cored wire. Install the roller with the groove that matches your wire facing the wire path, as your manual describes.
Can I use it for aluminum wire?
The listing does not describe aluminum use. Aluminum feeding normally needs a different groove profile, a suitable liner and gentle drive pressure, so choose a roller made for aluminum instead.
How do I know the drive roller is worn?
Common signs are wire slipping even at correct tension, uneven feeding, shiny or flattened grooves and birdnesting at the drive rolls. Check the liner, tip and tension before blaming the roller.
