040216 - Miller OS-351 Replacement Spot Welding Tips (Pair)

Genuine Miller Replacement Spot Welding Tips

Ensure the continued performance and reliability of your Miller portable spot welding equipment with the Miller 040216 OS-351 Tips. These genuine replacement tips are engineered specifically for use with Miller's renowned line of resistance spot welders, including the MSW-41, MSW-41T, LMSW-52, and LMSW-52T models. Sold as a pair, these tips are essential consumables for any fabrication shop, maintenance department, or industrial facility utilizing portable resistance welding for sheet metal assembly.

Manufactured from high-grade copper alloy, the OS-351 tips are designed to withstand the intense thermal cycling and mechanical pressure inherent in the spot welding process. Resistance welding relies heavily on the conductivity and geometry of the electrode tips to focus current and create a secure nugget between metal sheets. Over time, tips can mushroom, pit, or oxidize, leading to inconsistent welds, increased resistance, and potential equipment overheating. By replacing worn tips with genuine Miller 040216 units, operators can restore the machine's original efficiency, ensuring clean, strong welds with minimal spatter or surface indentation.

The OS-351 tips feature a precision-machined interface that fits securely into the standard tongs supplied with Miller portable spot welders. This secure fit is critical for maintaining proper alignment and preventing arcing at the connection point. Whether you are working on mild steel, galvanized sheet, or stainless steel applications, having fresh tips ensures that the welding current is delivered effectively to the workpiece. These tips are suitable for a wide range of industrial applications, from HVAC ductwork fabrication to light-gauge enclosure assembly and general metal repair.

Maintenance of your spot welder is key to longevity. Regular inspection of the tip face is recommended. While minor dressing can extend the life of a tip, eventual replacement is inevitable to maintain weld quality standards. The Miller 040216 package provides a convenient, direct-fit solution that minimizes downtime and eliminates the guesswork associated with universal or aftermarket consumables. Trust in Miller's OEM quality to keep your production lines moving and your welds holding strong.
