1. A welding method for arc welding a first coil and a second coil by use of an energized electrode, the welding method comprising:
a first step of detecting one of the first coil and the second coil, the one having a shorter distance from a tip surface to be welded to a tip of the electrode;
a second step of abutting the tip of the electrode on the tip surface of the one detected in the first step; and
a third step of generating an arc by separating the tip of the energized electrode from the tip surface of the one detected in the first step, after the second step, and arc welding the first coil and the second coil to join the first coil and the second coil together at a tip of the one detected in the first step.
