I. Introduction
Inverter Welding Controller Advantages
The output for the middle frequency inverter is direct-current waveform. This results
in more straightforward control of the welding process, shorter welding time, and
more consistent welding quality. The welding controller power source frequency is 1
kHz, as opposed to the traditional 50 Hz power source, which allows for much more
precise heat control.
Inverter output voltage Corresponding Output welding current
Compared to traditional welding controllers, the middle frequency inverter has the
following advantages:
1. The welding current is DC, therefore the welding current is less influenced by
inductance from the secondary circuit.
2. Smaller welding transformer is required
3. Increased electrode life cycle
4. Thinner materials, three-layer materials, and materials such as aluminum and
zinc-plated metal can be welded with good results
5. Precision welding
6. Minimized explosions
7. Spot weld quality improves greatly due to better electric current control

After the three-phase AC 50/60Hz input goes through the rectifier, the filter turns the
smooth direct current, makes the switch component by IGBT/K1 to have the
alternate voltage output, realizes the hypothesis welding current output through the
adjustment high frequency (5KHz) work's IGBT/K2 clear pulse width.
1. Variable Frequency vs. Normal Frequency Controller Comparison
Compared to common power welding controller shows the variable frequency
welding controller to have higher heating efficiency and lower peak current.
