Do I need less KVA for an MFDC transformer than an AC transformer?

Posted on November 13, 2020January 4, 2021 by Bob Cohen

For resistance spot welding, resistance projection welding, and resistance seam welding, the RMS current needed to weld a specific material of a specific thickness will be similar for MFDC as for AC. If all things are considered equal, where the only variable is the weld transformer type, the same KVA MFDC or AC transformer is […]
