Miller FasTip .052 Contact Tips PK25

This pack contains 25 tapered contact tips compatible with Miller FasTip series guns including Spoolmatic 15, Spoolmatic 30, XR-Aluma-Pro and XR-Pistol models. Each tip accepts aluminium wire up to .052 inch diameter and uses a threaded connection for secure fit. The heavy duty rating suits demanding workshop use.

Suited for Aluminium MIG Welding

Welders running aluminium wire on compatible Miller guns will find these tips match the original equipment specification. Shops using other wire diameters, different gun series or non-threaded tip designs must select alternative parts as these tips are specific to the listed FasTip models and .052 inch aluminium wire.

Maximum Current 400 Amp Rating

The single specification that decides fit is the 400 amp maximum current rating combined with the .052 inch wire diameter for aluminium. Verify your gun model appears in the compatible list — 130831, 195156, 198127 through 198130, 300001, 300003, 300004 and 301568 through 301573 — before ordering.

Questions about this item

How do I install the FasTip tapered contact tip .052 on my MIG gun and what step is often missed?

Thread the tip into the FasTip nozzle until it seats firmly; the step often missed is verifying the tip sits flush with the nozzle bore so the .052 aluminum wire feeds without resistance.

What maintenance or replacement will the FasTip tapered contact tip .052 need during regular use?

Replace the tip when the .052 bore shows visible wear, keyholing, or when aluminum wire feeding becomes erratic; heavy-duty rating means longer intervals but inspection each spool change is recommended.

What limit appears first when running the FasTip tapered contact tip .052 at high output for extended periods?

The 400 A maximum current rating is the first limit; sustained operation near that level accelerates tip erosion and can cause the .052 aluminum wire to overheat and stick.
