ABSTRACT:
A welding expectation path is taught beforehand, and an operation for striking an electric arc is executed at a point on the path. If the electric arc does not appear, the operation for striking the electric arc is executed at a different point on the path. When the electric arc has appeared, a welding torch is once returned to a welding start expectation point while the electric arc is held, and it performs welding from the welding start expectation point toward a welding end expectation point.
