[0002] Resistance welding machine refers to a welding device that uses the principle of resistance heating for welding, and is widely used in automobile parts. Resistance welding machines can be divided into different types according to different uses and requirements, and classified according to welding methods, including spot welding machines, seam welding machines, projection welding machines and butt welding machines. Resistance welding machines are mainly composed of main circuit parts, pressure transmission parts and control parts.

[0003] The wiring harness terminal is an accessory used for electrical connection. It connects wires of different colors and functions and enables electrical energy to flow reasonably between different electrical appliances. When producing and processing terminals with wiring harnesses, a resistance welding machine is usually required to weld the ends of the wiring harness to enhance the performance of the wiring harness.
