Our new closed-loop control circuit enables us to form a low-splash arc with minimal spatter on any type of material. We've also improved our arc control technology by adding an arc selector that allows users to choose their preferred shape quickly and easily. You'll be able to get high-speed welding performance while staying safe at all times—with multiple protection functions like output short-circuit protection, overheat protection, inverter overcurrent or overvoltage protection included!
Our output cable is 50 meters long and can handle long distances without getting damaged or damaged by water or wind. We have designed it so it's not only durable but also helpful for those working in difficult conditions where there are lots of obstacles within reach—like scaffolding or swinging scaffolds around buildings
