The invention discloses a DSP (
Digital Signal Processor) high-frequency
inverter table type miniature
spot welding machine, which relates to the technical field of electric
welding machines, and comprises a
machine tool, a
welding host is fixedly mounted in the
machine tool, a linear driving mechanism is fixedly mounted at the bottom of the inner wall of the
machine tool, and a
spot welding machine main body is fixedly mounted at the output end of the linear driving mechanism; a heat dissipation device is fixedly installed on the outer side wall of the
machine tool, a three-color lamp is fixedly installed at the top of the
machine tool, a rectangular plate is fixedly installed at the bottom of the inner wall of the machine tool, and a rectangular groove is formed in the face, close to the
spot welding machine body, of the rectangular plate. The fixing device comprises a pull rod, a carrying table, a loading disc, a
welding piece, a sliding table, a flexible block, a
tungsten filament, a linkage plate, a rubber plate, a pushing plate, a first spring and a limiting rod, the welding piece and the
tungsten filament are attached through standard operation, an operator can conveniently adjust the attaching angle in a safe area, and the spot welding quality can be improved.
