In the present invention, a tip case (3) accommodates a plurality of contact tips (10) linearly in a horizontal direction and in an orientation in which distal ends of the contact tips (10) face downward. A back-and-forth driving mechanism (5) causes the tip case (3) to move back and forth in the direction in which the contact tips (10) are arranged in a row, causing the tip case (3) to advance into and retreat from a tip supply space (S2). A tip extraction mechanism (6) upwardly extracts the contact tips (10) from the tip case (3) in a state in which the tip case (3) has advanced into the tip supply space (S2). A grip rotation mechanism (4) helically links the contact tip (10) extracted by the tip extraction mechanism (6) to a torch body (11), or removes the contact tip (10) from the torch body (11).
