250 A Transformer Regulator ARC Welding Machine

An arc welding machine is a device used for fusing metals. The machine emits an electrical arc from an electrode which melts metal or supplies filler into a joint between two pieces of metal. To produce the temperatures up to 3,600ºC needed to fuse metals, arc welding machines consume significant quantities of energy.The four main types of welding are: Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), and Flux Cored Arc Welding (FCAW).
