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.
