Product Description
The portable spot welding machine adopts a modular design, integrating welding transformers, cylinders, solenoid valves, water and gas distributors, rotating rings and suspension rods, balance systems, and control handles and other related devices into one. The main electrical circuit adopts a three-phase AC 380V/50HZ input, which passes through the controllable silicon in the controller and then to the transformer. After being reduced in voltage by the transformer, the secondary output is low voltage (4.75-10V) and large current (12-20KA) between the electrodes. The controller adjusts the conduction angle of the controllable silicon to adjust the output current of the transformer to meet the requirements of welding specifications.
