Spot welding machine is used to join two or more metal parts together by applying heat and pressure to a specific spot or area. The machine works by passing an electric current through the metal parts, which generates heat and causes the metal to melt and fuse together. The heat is generated by the resistance of the metal to the electric current. The pressure is applied by the welding electrodes, which clamp the metal parts together during the welding process. Spot welding machines are commonly used in the automotive, aerospace, and construction industries, as well as in the manufacturing of appliances, electronics, and other metal products.
Compare to single point spot welding machine, multi-point automatic welding machine have more advantages as below:
1.Each point parameter adjust independently, Welding point strength uniform.
2.Using constant conduction angle discharge control method, good consistency of welding current.
3.Automatic counting during welding, manual reset.
