To provide a high speed rotating automatic arc welding device having suitability to the welding on-site at a high position and high welding efficiency in high welding quality.
This device is composed of rail 5 parallel fitted with a welding line 201 extended in the perpendicular direction in a work 200 with plural magnet devices 6, an automatic welder 10 vertically welding downward by the high speed rotating arc welding with a rotation welding torch 1 through an arc sensor while travelling on the rail 5, a welding condition setting panel of a welding control device having handles for setting the welding condition and an operational pendant for finely adjusting the welding condition at an operator side. Then, a semi-automatic welding torch 20 is inserted into a connecting metallic tool at the base end side of the rotation welding torch so as to be freely attached/detached and commonly supply a welding electric source, shield gas and welding wire.
