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. Can be used for argon arc welding, manual welding, 5mm carbon arc gouging;
4. Reliable, flexible and accurate digital control system, adjustable parameters include pre-gassing time, arc starting current, ramp-up time, peak current, base current, pulse frequency, duty cycle, ramp-down time, and arc-ending current , post-aeration time, etc.;
5. High-speed DC pulse waveform output, the highest frequency can reach 200Hz, the arc is more rigid, the heat-affected zone is small, and it is more suitable for thin plate welding;
6. With overvoltage, undervoltage and phase loss protection, it can effectively protect the welding machine from the harsh power supply environment;
7. Applicable to generators and any grid voltage between three-phase 320V to 520V;
8. With water cooling interface, optional water cooling components.
