Compatible nozzle insulator for MIG guns

The Miller Enterprises C-3010 insulator fits FasTip and Roughneck C-Series consumables including models 3010, 3012, 3015, 4010, 4012, 4015, 5010, 5012 and 5015. It is intended for welders running MIG (GMAW) processes who need a direct replacement insulator for their existing Roughneck gun setup.

PTFE construction for daily welding use

Moulded from black PTFE, the insulator withstands the heat and spatter encountered during routine MIG welding. The material resists sticking and carbon build-up, so the nozzle seats cleanly each change and the thread engagement remains consistent across shifts.

Exact model match decides fit

Selecting the correct part number — 3010, 3012, 3015, 4010, 4012, 4015, 5010, 5012 or 5015 — is the only specification that determines whether this insulator will seat properly on your Roughneck gun. Buyers who need a different series or a non-FasTip design will not be served by this item.

Questions about this item

Does the C-3010 insulator fit the Roughneck C-Series FasTip nozzles?

Yes, the C-3010 insulator is compatible with Roughneck C-Series FasTip nozzles including models C-3010, C-3012, C-3015, C-4010, C-4012, C-4015, C-5010, C-5012, and C-5015.

What material is the C-3010 insulator made from?

The C-3010 insulator is made from PTFE, a heat-resistant material suited for MIG welding (GMAW) applications with Roughneck guns.

How is the C-3010 insulator installed on the welding gun?

The insulator threads into the nozzle body; ensure it is seated fully and the threads are clean to prevent gas leaks or cross-threading.
