This welding machine is mainly used for refrigeration, air conditioning refrigerator condenser, evaporator copper tube and aluminum tube welding,
Full button operation, high safety, solid and reliable joint after welding, leakage rate of 0.001%, tension up to 13Mpa, stronger than copper copper brazing. This industrial welding equipment also welds a variety of metal round, flat, pipe and profile.
Constant current control: stable current, high yield, inverter controller inverter output adjustable sine wave, current detection closed-loop control, current fluctuation<1%.
Save energy: work conversion frequency is high, transformer loss is small, welding the same workpiece than the AC welding machine energy saving 27%-50%.
One-click operation: humanized interface, set the parameters, as long as the two buttons on the stage at the same time that automatic welding, simple operation.
Easy maintenance: the use of single chip microcomputer as the main control unit, the circuit is simple, highly integrated intelligent, reduce the failure rate, more convenient maintenance and maintenance.
