1. The whole machine and all parts are designed with three-proof, high reliability;

2. The power devices are all selected from well-known brands, and the core device IGBT is selected from Infineon, Germany;

3. The digital control system based on 32-bit ARM processor can reliably, flexibly and accurately adjust the air supply time, arc starting current, ramp-up time, peak current, base current, pulse frequency, duty cycle, cleaning effect, AC frequency, slow down time, crater current, post air supply time, etc.;

4. In AC mode, rectangular wave, triangular wave and sine wave can be selected for different welding requirements;

5. Special arc starting design ensures 100% cold gun arc starting under AC state;

6. The cleaning effect is flexible and adjustable to ensure that the welding seam is bright and beautiful;

7. High-speed DC pulse waveform output, the highest frequency can reach 200Hz, the arc is more rigid, the heat-affected zone is smaller, and it is more suitable for thin plate welding;

8. With overvoltage, undervoltage and phase loss protection, it can effectively protect the welding machine from the harsh power supply environment;

9. Applicable to generators and any grid voltage between three-phase 320V to 520V;

10. Equipped with water cooling interface, optional water cooling components.
