Compatible Liner for Roughneck MIG Guns

This 15 ft steel and copper liner fits Miller Roughneck C-Series guns including models C-3010, C-3012, C-3015, C-4010, C-4012, C-4015, C-5010, C-5012 and C-5015.

For MIG Welders Using Supported Guns

Welders running a compatible Roughneck gun with wire in the .052 to .063 in range can use this liner as a direct replacement. It is not suited for flux-cored or TIG processes, nor for guns outside the listed C-Series models. Buyers needing a different wire size or a liner for a non-Miller gun should look elsewhere.

Wire Diameter Range .052 to .063 in

The liner accepts solid wire no smaller than .052 in and no larger than .063 in. Using wire outside this window will cause feeding problems or excessive wear. Verify the wire diameter on your spool before ordering.

Questions about this item

What gun models does the 15 ft liner with part number 202891 fit?

The liner fits Roughneck C-Series guns including models C-3010, C-3012, C-3015, C-4010, C-4012, C-4015, C-5010, C-5012 and C-5015.

How do I install the steel/copper liner so the wire feeds correctly at the .052-.063 in range?

Trim the 15 ft liner to match your gun length, insert it fully into the power cable until seated at the diffuser, then secure the retaining nut without kinking the liner.

When should I replace the liner if I run .063 in wire daily?

Replace the liner when wire drag increases, feeding becomes erratic or the steel/copper surface shows visible wear grooves from the .063 in wire.
