80KW 380VAC Portable Mini Ultrasonic Spot Welding Machine 80KVA

80KW 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.
Functional features:
·High precision slide rail type motion mechanism
·Stable welding current of pressurizing mechanism
·Contactless switch adjustment
·High level single chip microcomputer fast control
·Constant current and constant voltage output adjustable closed-loop control
·Automatic protection of overload and lack of voltage
·Output current monitoring
