ERW Solid State High Frequency Welding Machine
ERW Solid State High Frequency Welding Machine Description
ERW Solid State High Frequency Welding Machine is specially designed for straight seam welding. It adopts high power components of US IR IRFP460 MOSFET and Germany IXYS Company DSEI60-06A rapid recovery diode. The high power capacitor C and inductor coil L compose current-mode parallel upper-voltage resonance circuit, which doesn’t need output transformer. Thus, it not only improves the efficiency, but also increases the reliability of the welder.It includes Inverter Unit, DC power Unit, Central Control Unit, Water-water(air-water) cooling Unit, Rectifier Isolaiton Transform.
The whole set of ERW solid state high frequency welding machine comprises of rectifying cabinet, inverter and output cabinet, connecting optical fiber, closed loop water cooling system, central operator console, mechanical adjustment device, etc … Solid state welder is used to be a high performance-heating unit controlled by computer for welding steel pipe.
