Abstract
A welding control unit has a common power section for detecting contact of a welding material and for welding. A material contact detector for detecting contact of the welding material and a workpiece, and a power controller are built in the welding control unit. This stabilizes a bead shape in starting welding. The number of components can also be reduced, resulting in more inexpensive equipment. In addition, only a space for installing the welding control unit is needed without any additional space.
