Introduction:

Transistor spot welding machine is a high frequency pulse precision welding machine. Based on the capacitor energy storage spot welding machine, transistor switch is added, which is called FET switch. The power of a single FET switch is generally insufficient, so dozens or hundreds of transistor switches are usually connected in parallel to control and discharge through capacitance.

Generally, the speed of discharge is very fast, and the current should be controlled in a short time, so the transistor spot welding machine is generally controlled by a high-performance single-chip microcomputer, which outputs high-frequency pulse signals to control the transistor switch state.

Features:

1. Technical features of transistor welding power supply: 3000 / 4000 / 6000 is a high-speed switching power supply with high-precision and high current, which can realize closed-loop feedback control of the real-time collected voltage between welding electrodes and current.

2. Continuous and simple input power supply, low capacity (220V, 10A)

3. 100-150KHz leading control speed, fast rising speed of welding current, and precisely adjustable.

4.3 control modes (constant current, constant voltage, current voltage hybrid)

5. Display the real-time dynamic waveform of current voltage resistance power heat at the same time, which is convenient for welding quality management.

6. The real-time dynamic list displays the welding parameter test data of the last 10 spots.

7. It can set 31 groups of storage ie specifications, and can switch at will.

8. Equipped with pre power on detection function, it can judge the working state of welding path.

9. Standard RS-232 / 485 communication function.
