MMA-400 inverter manual arc welding machine adopts advanced IGBT inverter technology, with high inverter frequency and excellent welding performance.

1. Constant output, making the output current more stable; fast dynamic response speed, reducing the influence of arc length fluctuation on current;

2. The equipment has self-protection functions such as overvoltage, undervoltage, phase loss, and overheating. When the above situation occurs in the electric welding machine, the equipment will automatically cut off the current and prolong the service life of the welding machine;

3. Industrial-grade welding performance, adjustable arc thrust and thermal arc starting parameters, built-in anti-stick function, and high welding seam forming quality.

4. VRD intelligent anti-electric shock protection, the no-load voltage of the welding machine is lower than DC24V, safe and reliable.

5. High load duration, suitable for industrial places. Under the condition of 40℃, the continuous load rate can reach 60%, which ensures the continuous operation of welding production.

6. Wide range of applications. Such as petroleum, chemical industry, machinery, shipbuilding, military industry, nuclear power, etc.

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. Industrial-grade welding performance, adjustable arc thrust and thermal arc parameters;

4. Self-contained anti-stick function to ensure the quality of weld forming;

5. Special arc starting circuit design to ensure the success rate of arc starting;

6. The special heat dissipation design ensures that the load duration rate can reach 60% at a temperature of 40 °C, which improves the reliability and work efficiency of the whole machine;

7. Small size and light weight, especially suitable for applications where the station is not fixed;

8. The no-load voltage is high, and the welding tongs and the ground cable can be extended to 100 meters at the same time;

9. VDR anti-electric shock function, very suitable for special occasions such as large containers and shipyards;

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

     11. It can be applied to generators and any grid voltage between three-phase 320V to 520V.
