700KW High Frequency Pipe Welding Machine

How it works:

Ordinary three-phase alternating current (line voltage 380V, frequency 50HZ) is stepped-down by the transformer (line voltage 200V, frequency 50HZ), enters the rectifier cabinet and becomes 0 to 240V continuously adjustable direct current after rectification, voltage regulation and filtering; It then enters the inverter bridge (using a high-power transistor MOSFET) and becomes a high-frequency current, which is supplied to the load trough and can be used for induction heating.

The inverter trough power unit adopts a modular structure, each pair of power units can output more than 50KW, the power of the equipment is different, the number of power units used is different, and the basic structure of the equipment is the same regardless of the size. The trough is in the form of series-parallel mixed resonance, there is no high voltage, and there is no output transformer. The number of power units used in this equipment is fourteen pairs.

The main advantages of TENYES 700KW High frequency pipe welding machine:

1. No high voltage, safe, reliable and efficient

2. The main components are imported products, such as: IR, IXYS and Siemens.

3. Pulse-width modulation or microcomputer control voltage regulation circuit is adopted, with stable adjustment, high precision and small harmonic interference.

4. The power range is stepless adjustable from 0-100%, with over-voltage, over-current and other fault protection systems.

5. The working status display is digital, the operation is simple, and the maintenance is convenient.

6. The welding quality is good, the width and heat of the weld are uniform, and there are few internal and external burrs.

Scope of application:

Steel pipe welding, stainless steel pipe welding, aluminum tube welding, copper tube welding, H-beam welding, special-shaped tube welding
