Are you looking for a high-quality high-frequency welder with excellent performance?
The whole set of solid state HF welder comprises of the following seven parts: rectifier cabinet, transformer, inverter cabinet, console, 2D adjustable bracket, water cooler and output leg.Solid state HF welder is designed for straight seam induction welding of steel pipe and for continuous working., the whole set of equipment achieve the function of equipment linkage control and diagnosing faults by PLC system, the working statue is observed by LCD display.
Vacuum tube | Original solid state | New solid state | Remark | |
Nominal power | 100KW | 100KW | 100KW | |
Tank circuit voltage | 12000V | 12000V | 450V | |
Power Definition | Oscillatory power | Output power | Output power | |
Resonant method | 3 points Capacitive type | Series resonance | Compound resonance | |
Efficiency e | （50-60）% | 70% | 85% | Jumps（10-15）% |
Work voltage | High voltage equipment | Tank circuit voltage is high | Low voltage and high reliability | |
Rreliability | The failure rate is lower | The breakdown are few, but services inconveniently | The fault less easy to service | |
Maintenance costs | Lower | Lower | Low | |
Working life | 1500 hours for vacuum tube | Long term | Long term | Vacuum tube need to change regularly |

Q: Are you manufacturer?
A: Yes. We are manufacturer. We have our own technical team. Welcome to visit us.
Q: What payment terms do you accept?
A: We are flexible on payment terms, please contact us for details!
Q: What info you need before you make the proposal?
A: The pipe diameter and thickness range which you need or the profile drawings material information, your special requirements and speed of the machine.
Q: How do you do QA?
A: We have special team do strict QA, this is our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure it is in the range of tolerance critical parts will be inspected for all dimensions.
