100kHz-20000kHz 300kw Carbon Steel Pipe Welding Machine Energy saving

300kw Solid State Steel Pipe/Tube H.F. MOSFET Welder

Product Introduction:

Solid state H.F welder 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.
