Miyachi Unitek manufactures a range of weld controls, heads, spot welders, welding machines, weld monitors and weld checkers, spot welding equipment and accessories – including welding electrodes - for large scale spot welding. We have more than 50 years’ experience solving customers’ manufacturing challenges, enabling us to offer you the fastest path from fledgling application to full production.

Most “large scale” resistance spot welders use parts made of galvanized low carbon 1010 and 1100 cold roll steel with 304, 316, and 400 series low carbon stainless steels ranging in thickness from .016 inches (0.41 mm) to .062 inches (1.57 mm). Typical applications for spot welders include automotive subassemblies, appliance subassemblies, projection welds, wire harness welding, and bi-metal contact welding. Resistance spot welding technologies offered include both Inverter and AC weld controls. With 8 primary models and an almost infinite number of custom configurations offering up to 4000A output, our large scale resistance spot welding machines can address most industrial welding applications.
