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

1. Constant output, making the output current more stable; fast dynamic response speed, reducing𒅌 the influence of arc length fluctua⛄tion on current;

2. The equipment has self-protection functions such as overvoltage, undervoltage, ph♓ase loss, and overheating. When the above ಞsituation 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 ant♍i-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 c🐭ontinuous operation of welding ౠproduction.

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 ♊reliabil♌ity;

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

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

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

5. Specia🐠l arc starting circuit design to ensure the succ✱ess rate of arc starting;

6. The special heat dissipation design ensures that the load duration rate can reach 60% at a temperature of 4ꦦ0 °C, which improves the reliability and work efficiency of the whole machine;

7. Small size and light weight, especially suitable for applica🧸tions 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 meter🐟s at the sam꧂e time;

9. VDR anti-electric shock function, very suitable fꦰor special occasions such as large contai🃏ners and shipyards;

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

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