15 ft .035–.045 in Welding Conduit Liner
This 15 ft steel and copper liner fits Miller Roughneck C-Series guns. It supports MIG welding with wire diameters from .035 in to .045 in. The grey and white liner replaces model 202890 on compatible machines.
Who This Liner Fits
It suits welders using Roughneck C-3010, C-3012, C-3015, C-4010, C-4012, C-4015, C-5010, C-5012 or C-5015 guns. It does not suit flux-cored setups that require larger wire sizes or operators needing a shorter or longer liner length.
Wire Diameter Range .035–.045 in
The critical spec is the .035 in minimum and .045 in maximum wire diameter. Select this liner only when your wire falls inside that range and your gun model appears in the compatibility list.

Questions about this item
What gun series and models does the 15 ft C-3010 liner fit?
It fits Roughneck C-Series guns including C-3010, C-3012, C-3015, C-4010, C-4012, C-4015, C-5010, C-5012 and C-5015.
How do I install the liner and what step is often missed?
Remove the old liner, feed the new steel/copper liner through the gun cable, trim it flush at the contact tip, and secure the retainer — many forget the flush trim.
When should I replace the liner on my MIG gun?
Replace it when wire feed becomes erratic, the liner shows kinks or wear, or after heavy use with .035-.045 in wire — typically every few wire spools.
