<p>[Problem] The present invention provides a welding apparatus capable of switching welding wires without adversely affecting operation. [Solution] In switching an in-use MIG welding wire (22) to a brazing welding wire (20), the MIG welding wire (22) is cut, the tip of the welding wire (22) extending from a welding wire supply tube (23) is then bent so as to prevent the welding wire (22) from being pulled into the welding wire supply tube (23), and the welding wire (22) remaining in a welding wire supply apparatus (13) is pulled out. After that, a registering pin (28) is removed, a wing bolt (30) is loosened, and a swinging member (16) is rotated clockwise around a shaft (17). As a result, a limit switch (24) is turned off, and a limit switch (25) is turned on.</p> |
