Until now, you would spot-weld primarily by using a large resistance welder. But now, you can use your MIG welder together with this Spot Welding Kit from Eastwood to achieve the same professional results.
Spot welding is accomplished by clamping two panels together and fusing them with a number of sequentially-placed welds, rather than in a continuous bead, to hold the panels together. This kit is designed to be used with any brand welder that utilises a Tweco®-style MIG torch.
The combination of the Spot Pliers and Spot Nozzle assures complete welds all the way through, and exact duplication of each spot weld.
For 18-gauge steel, or if you're using a less-than-175-amp MIG welder, simply use the supplied double-ended HSS drill bit to drill a 0.187" pilot hole in the top panel only, and then complete the spot weld as usual. The pilot hole serves to assure complete and full penetration from the top to the bottom panel. This type of weld is far greater in strength than a simple resistant spot weld, but produces the exact OE look, with greater weld strength.
