Solid state H.F welder adopts the most advanced fixed-angel phase-locking control technique, inverter working status do not change as load tank circuit change, which keep the work at the best small sensitivity resonance status all the time, welder works stably with high efficiency.

    Solid state H.F welder has advanced functions like high/low lock-lost protection, frequency upper limit/lower limit protection, inverter over-current, tank circuit over-voltage., etc. Also more accurate and efficient on open-circuit, short-circuit, arcing of inductor malfunction, it guarantees welder stable running.

    Besides regular protections, each inverter bridge adopts multiple protections, such as DC side over-current, AC side over-current, AC side over-voltage., etc. It realizes protection redundancy, guarantees inverter safe running.

    Rectifier control circuit has soft startup, soft stop function which prevents welder over-current and over-voltage caused by rising too much of current and voltage when startup/stop.

   It adopts matching transformer to realize electric isolation and load matching of solid state H.F welder with merits of whole set high efficiency, easy matching regulation.

    The welder has large power allowance, when in good load matching conditions it allows running under 110% rated power for a long time.

    Wide range capacity available, ranging from 100KW to 1200KW to meet customers' demands.
