About This Product
Spot welding joins overlapping metal sheets by passing current through them between two electrodes at a single point. This machine is built around an encapsulated transformer with a low-loss secondary circuit, and its water-flow cut-off switch covers the transformer, thyristor and inverter. With AC ratings from 50 kVA to 340 kVA and an MFDC option, it suits resistance welding instruction in a fabrication workshop.
