In general, various welding techniques such as SMAW welding, MIG welding, TIG welding, PLASMA welding, and LASER welding are usually composed of a torch, a wire feeder device, and a welding power source.

Use the positive electrode (+) and negative electrode (-) of the welding power source to conduct electricity between the base metal and the filler metal. That is, it is possible to generate an arc between the base metal and the filler metal. At this time, the filler metal is molten metalized while filling the molten portion of the base metal, whereby welding is performed.

Various welding techniques such as SMAW welding, MIG welding, TIG welding, PLASMA welding, and LASER welding are classified into manual welding, semi-automatic welding and automatic welding according to the welding method.

On the other hand, in the automatic welding system, it is difficult to perform the welding operation of the entire welding product with one welding machine. Therefore, after a certain amount of welding operation is performed in one welding machine, the welding product is moved back to another welding machine, and then the welding will be performed.

However, this method has a problem in that workability as well as productivity are lowered because the welding product must be manually moved one by one to another welding machine after one welding is performed, and then the welding operation must be performed again.
