Equipment composition:

1. Rectifier cabinet

2. Rectifier transformer

3. Inverter cabinet

4. Console

5. Air-water cooler exchange

①Rectifier cabinet: with filtering, isolation, logic control system and reactance full-wave filtering circuit. Ensure the continuity and smoothness of the DC power supply, strong anti-interference ability, and no harmonics and clutter. The power supply of the control circuit board and the power component board adopts the switching power supply, which ensures the stability of the power supply system and the wide adaptability of voltage. The output DC voltage is continuously adjustable, and the maximum DC voltage is 250V, which greatly improves the safety of operators.

② Rectifier transformer: transformation ratio of 400V/205V.

③Inverter cabinet: LC oscillating circuit composed of power capacitor and inductance coil. All power component boards use transistors as the power unit of the template. This LC oscillating circuit is different from the oscillating circuit of the electronic tube mode. The tank circuit capacitor C directly resonates with the induction coil L, and there is no output transformer, which greatly reduces the loss and improves the output efficiency (the efficiency is 25%-30% higher than that of the High frequency vacuum tube welder).

④Central console: simple and convenient to operate.

⑤Air- water exchange system: It is composed of heat exchange, circulating pump, water separator and electrical control part.

Central Console

Welding Arm

High frequency welding machine is a new type of induction heating equipment, mainly used for welding of metal pipe fittings, welding of alloy tools, welding of carbide saw blades, welding of diamond saw blades, welding of marble saw blades, etc.
