Abstract
An automatic welding method and an automatic welder in which welding conditions are automatically set in compliance with the position or posture of a welding torch relative to a work piece and the welding path. The direction of gravity is added as one of parameters necessary for automatic setting of the welding conditions and the welding condtions are controlled to comply with changes in the welding torch position relative to the gravitational direction and the welding path, thereby ensuring that the automatic welder can be realized which can be installed to face to any directions and that work pieces having various profiled and welding paths can be welded automatically with high quality.
