Spot welding device for resistor machining

The invention discloses a spot welding device for resistor machining, and relates to the technical field of resistance welding, the spot welding device comprises a mounting base, a supporting column is fixedly connected to the top of the mounting base, an electric energy device is arranged on one side of the supporting column, and an electrode column mechanism I is fixedly connected to the lower portion of the electric energy device. The technical problems that splash generated by welding is prone to hurting workers, welded objects are inconvenient to directly take due to the high temperature, and no good measures are taken to place the welded objects are solved, a first electrode column mechanism is arranged, an external draught fan is arranged through an air inlet, and a second electrode column mechanism is arranged; the fan is used for extracting outside air and discharging the outside air through the exhaust holes to blow away splashes generated during welding, so that workers are prevented from being hur
