Arbetsprincip för elektrisk svetsutrustning

The working principle of electric welding equipment is to melt the welding rod and the material to be welded by electric energy, and combine them together by high-temperature arc. The electric welding machine is essentially a high-power transformer that converts 220V and 380V AC into low-voltage DC or AC. Through the principle of inductance, it generates huge voltage changes when ansluten och frånkopplad och antändar därmed bågen .
