    Why does Miller Welding Accessories wire feed erratically?
    • B
      Brenda PhillipsAug 17, 2025
      Erratic wire feeding can occur due to several reasons. Try these solutions: 1. Readjust hub tension and drive roll pressure. 2. Use the correct size drive roll. 3. Clean or replace a dirty or worn drive roll. 4. Remove weld spatter around the nozzle opening. 5. Replace the contact tip or liner. If these steps don't resolve the issue, have a Factory Authorized Service Agent check the drive motor and control board PC1.

      If the wire is not feeding, you can try the following: 1. Check supplementary protector CB1. 2. Check the gun trigger connection at the wire feeder, the gun trigger leads, and the trigger switch. 3. Ensure the Run-In speed is not set to minimum; the normal setting is 50 percent. If the problem persists, have a Factory Authorized Service Agent check the drive motor and control board PC1.
