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.
