040228 - Miller Spot Weld Tip Dresser for No. 4 Electrodes

Keep Your Spot Welder Running Like New

Every welder knows that the key to a good spot weld is a clean, sharp tip. When your spot welder tips start to flatten out or "mushroom" after repeated use, the power spreads out over a larger area, making your welds weaker and less reliable. The Miller 040228 Tip Dresser is the perfect solution for this common problem. Designed specifically for No. 4 RW electrodes, this handy tool lets you reshape your tips in seconds, bringing them back to their original condition without having to remove them from the machine.

Using this tip dresser is simple and effective. It shaves off the deformed copper edges and cleans up the face of the electrode, removing any burn marks or buildup that can interfere with the electrical connection. This means you get a focused, hot arc every time you pull the trigger, resulting in professional-quality spot welds that hold tight. It is an essential addition to any shop using resistance welding equipment, saving you money by making your expensive copper tips last much longer before they need to be thrown away.

Don't let worn-out tips compromise your work. The Miller 040228 is compact, tough, and built by Miller—a brand welders trust. Whether you are working on auto body restoration, HVAC ductwork, or metal art, keeping this dresser in your toolbox ensures you are always ready to lay down perfect spot welds. It is a small investment that pays off with better performance and less frustration on every job.
