TIG-400 inverter DC pulse argon arc welding machine, type arc welding machine adopts advanced pulse width modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module. Automatic protection functions such as voltage loss, overheating, etc. When the above fault occurs in the arc welding machine, the front panel alarm indicator lights up, and the output current of the equipment is automatically cut off, which plays a role in self-protection and prolonging the service life of the equipment.

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.
