The solid-state high frequency welder device is designed for the induction (contact) welding of steel pipes. The high-power capacitor bank C and the inductor L form a current-type parallel boost resonant circuit. This circuit is suitable for high-frequency welded pipes with low load impedance and does not require an output transformer, which not only improves efficiency, but also increases the reliability of the whole machine.

- The equipment requires indoor installation and good grounding. The color of the grounding wire must be clearly different from the color of the control wire, and the grounding resistance is less than 4Ω.
- The altitude does not exceed 1000 meters, otherwise the rated value should be reduced.
- The highest ambient temperature should not exceed +40℃, and the lowest should not be lower than -10℃.
- The relative air temperature is not more than 85%.
- The installation inclination is not more than 5 degrees.
- No violent vibration, no conductive dust, no corrosive gas and explosive gas.
- Install in a well-ventilated place.
