3KW AC spot welder

     AC spot welder is a kind of machine that can firmly weld workpieces together. AC spot welding machine is composed of step-down transformer, current regulator, heat dissipation system, welding wire, handle and other accessories. During welding, there is no need to use welding electrodes, but only take the two pre welded workpieces as the two electrodes of the circuit, and use the high temperature generated at the contact resistance to melt the metal instantaneously, so as to firmly weld the workpieces together. It can be widely used in automobile, aviation, construction, machinery, metal products, electrical switches and other industries. It can carry out high-quality and strong brazing or brazing of various low-carbon steel, stainless steel and non-ferrous metal plates and wires.
