How To Metal Arc Welding. Both the metal joint and the electrode are melted at the same time and fused them together. The primary input lead is either 415 V or 240 V and should never be tampered with altered or repaired except by a licensed electrician.
This power source creates an electric arc between the tip of the welding instrument technically referred to as an electrode and the surface of the material being welded. As the welder steadily feeds the covered electrode into the weld pool the decomposition of the. Length of arc.
The primary input lead is either 415 V or 240 V and should never be tampered with altered or repaired except by a licensed electrician.
Once the surface is cleaned to a shiny surface you can connect the workpiece to a metal clamp and strike an electric arc to begin MIG welding. If the metal consists of two pieces that are to be joined in the welding process you may need to prep or weld prep them by grinding a beveled edge on the sides that are to be joined. The AC or DC current generated by the welding machine appears in. Upon cooling and solidification a metallurgical bond is created.
