1.1 The solid state H.F. welder adopts Germany IXYS company IXFN38N100Q2 38A/1000V high-power MOSFET and DSEI 2×61-12B 60A/1200V rapid recovery diode to compose series type invertible circuit.

1.2 The solid state H.F. welder adopts modularization design with more compact structure which makes maintenance and high-power realization much easier.

1.3 It has particular technology of bridge-divided over-current protection that guarantees equipment safety.

1.4 It combines international advanced control method of same products, adopts advanced technologies like fixed angle phase-locking control, upper frequency limit/lower frequency limit lock-lost protection and etc. With these technologies, the equipments run more stably, more efficiently, more accurate and effective protections to the inductor short-circuit and open-circuit malfunction during pipe welding production.

1.5 Speed-power closed-loop control system which is an optional installation to user, it highly improves welding efficiency and reduces technical adjustment period.

1.6 Line-in end of solid state H.F. welder does not need step-up /step-down rectifier transformer, compared with vacuum tube welder and parallel type welder; it has significant energy-saving effects (Under same welding condition, energy-saving ≥30% compared with vacuum tube welder).
