機。 A workpiece to be welded is sandwiched between the upper electrode provided on the upper electrode rod and the lower electrode provided on the lower electrode culm, and a pressurizing force is applied to the upper electrode rod with a pressure device to separate the upper and lower electrodes. A spot welding machine that performs spot welding by energizing the spot welding machine, which is provided with an electropneumatic proportional valve for setting the pressurizing force in the pneumatic circuit of the pressurizing device, which opens with a power ON signal and closes with a power OFF signal. Also, when the power is turned on, there is an on-off valve that maintains the pressure state on the secondary side of the electro-pneumatic proportional valve.
A spot welding machine characterized by being installed on the next side.
