CMT: Cold Metal Transfer - Digital Welding Solutions
www.digitalweldingsolutions.comcircuit metal transfer. The wire moves forward, and as soon as the short circuit happens, it is pulled back again. Automatically. In this way, the arc itself only inputs heat very briefly in the arcing period, after which the thermal input is immediately reduced. Hot, cold, hot, cold, hot, cold. Spatter-free metal …
