2 sets welder now run successfully at Bangladesh

One of our engineer fly to Bangladesh at beginning of Oct for commissioning work of the solid state hf welder . This customer ordered two sets HF welder from us. One is 100KW and the other is 200KW. Both sets is MOSFET & IGBT integrated HF welder . The welder can be widely used for round pipe , square tube , rectangular pipe and oval pipe. And the material for the tube mill can be MS carbon steel and GI . Due to the below features, our Bangladesh customer is quite satisfied with our induction welders .

Features of MOSFET & IGBT Integrated high frequency induction welder :

1. Using Germany IXYS company big power MSOFET IXFN38N100Q2 38A/1000V and fast recovery diode DSEI 2 X 61-12B 61A/1200V forming series resonance inverter circuit. The apparatus has a long life with a low failure rate.

2.Adopting modular design,the welder structure is more compact and more convenient to maintain.With all-in-one structure, it covers a small area,which could save room space.

3.Adopting PWM chop-wave technology ,with Infineon brand IGBT as switch component, it could provide load with fast,stable,and adjustable DC voltage and current, also it could increase 
the power factor of the machine, the power factor of the new generation welder is not less than 0.97.

4.Adopting Digital Phase-lock loop inverter control technology, with application of high speed DSP, the fixed angle control is realized, so that the load frequency can be tracked automatically to provide reliable drive pulse for inverter and ensure the high frequency induction welder running more stable and efficient.
