<p>An arc welding method capable of easily varying welding conditions such as welding speed, voltage and electric current. The method comprises the steps of teaching a start point to start varying welding conditions such as welding speed, voltage and electric current and an end point to terminate the variations of welding conditions such as the welding speed, the voltage and the electric current, as well as setting the welding conditions at the start point and the end point for gradually varying the welding conditions such as welding speed, voltage and electric current towards end point. By simply setting positions of the start point and the end point and the welding conditions at these positions, it is possible to gradually vary the welding conditions from the conditions at the start point to the conditions at the end point while a welding torch is moved from start point to the end point, thereby contributing to the simplification of the welding condition varying procedure. <IMAGE></p> |
