のとなる。A pressure cylinder 7 is arranged below the lower electrode 5, and the operation of the pressure cylinder 7 causes the lower electrode 5 to move up and down. In such a configuration, as described above, the work W is set on the upper guide pin 4 of the upper electrode 3 and the rod of the supply cylinder 8 is extended separately from the setting of the work W to attach the welding nut N to the lower electrode 5 in advance. It can be set on the upper surface, the pressure cylinder 7 is actuated to move the lower electrode 5 upward, and the welding protrusion Nb of the welding nut N is brought into contact with the work W to generate heat by causing an electric current to flow. N can be welded to the work W and spot welding can be performed. In comparison with the conventional structure in which the welding nut N can be set at a predetermined position only after the work is set,
In this example, the work W is set on the upper electrode 3 and at the same time,
Alternatively, before that, the welding nut N can be set on the upper surface of the lower electrode 5, so that if the worker sets the work W on the upper electrode 3, spot welding can be performed at the same time as the setting. Compared with this, the welding time of the welding nut N per one spot of spot welding can be significantly shortened, and the work can be performed at high speed.
