Features of new generation H.F. solid state welder 

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 technics 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). 

1.7The solid state H.F. welder designed with the most advanced electric-load-matching technology (PS+PWM control) which keeps solid state H.F. welder on a high welding efficiency, high power coefficient (>0.9), optimizing load matching status and can be switched under induction welding/contact welding double function mode.

Equipment composing

The whole set of solid state H.F. welder comprises of switchgear rectifying cabinet, inverter output cabinet, connecting optical fiber, circulation soft water cooling system, central operator console, mechanical adjustment device, contact welding pole plate and contact pin (contact welding) and etc.
