Restore Your Spot Welder's Performance

Get your Miller portable spot welder back in top fighting shape with the Miller 040216 OS-351 Tips (Pair). If you are a metalworker, auto body technician, or HVAC professional, you know that the quality of your spot welds depends directly on the condition of your tips. Worn-out, mushroomed, or dirty tips can result in weak bonds, ugly burn marks, and frustrating sticking. These genuine Miller replacement tips are the perfect solution to refresh your machine and achieve professional-grade results on your sheet metal projects.

Designed specifically for the popular Miller MSW and LMSW series portable spot welders, these tips are built to the exact specifications required for these machines. The kit includes two tips, allowing you to replace both the upper and lower contact points simultaneously for consistent electrical conductivity and pressure distribution. Made from durable copper alloy, they resist deformation under heat and pressure, providing a long service life even in demanding workshop environments. Whether you are restoring a classic car, building metal cabinetry, or repairing ventilation ducts, these tips help you produce clean, factory-look spot welds with ease.

Installation is straightforward and quick, allowing you to get back to work without lengthy interruptions. Simply remove the old tips from your spot welder tongs and install the new OS-351 tips, ensuring they are seated firmly. The correct tip geometry concentrates the welding current exactly where it's needed, creating a focused hot spot that fuses the metal sheets together instantly. This efficiency not only produces better welds but also reduces the strain on your welder's transformer and tongs.

Don't compromise on your tools. Using the correct consumables is the cheapest insurance for high-quality work. The Miller 040216 OS-351 Tips are an affordable investment in your equipment's capability. Keep a spare pair in your toolbox so you are never caught off guard by worn equipment in the middle of a job. With fresh tips, you'll notice an immediate improvement in arc initiation and nugget formation, giving you the confidence that every spot weld will hold tight for years to come.
