2021 Latest Design Solid State Igbt H.F. Welder Welding Carbon Steel Tube Straight Seam Erw Tube Mill Equipment - Parallel circuit 800kw Solid state hf welder for tube mill – Mingshuo

1. Low voltage and high current working mode

2.Two-stage LC filter, the output current is more stable.

3. MOSFET is used as the inverter element.

1. The control circuit is controlled by a microcomputer, and the rectifier board has two microcomputers to complete digital trigger and control functions.

2. The equipment has water pressure, water temperature, over voltage, over current, phase loss, phase sequence protection, short circuit, open circuit protection, etc., and provides digital display.

3. The inverter circuit has a frequency tracking function, so that the trigger frequency is always approximately equal to the tank circuit frequency.

4 With frequency display function, it is displayed by a four-digit digital tube, and the display accuracy is ±100HZ. Normal, adjust the tank circuit or check the feedback signal.

High-frequency welding machines can be used for welding alloy tools, such as alloy turning tools, milling cutters, planers, saw blades, reamers, boring cutters, etc.
