RilTech IS168 use Advanced IGBT technique and fast recovery diodes as main electric components.

It is supplemented by a specially developed main PCB board. In addition, the uniform regulation of welding current has been designed to guarantee the arc reaches good welding process adaptability.

What’s more, its perfect dynamic protection features ensure that it is safe and reliable when use.

It is ideal for using low carbon steel, stainless steel with all kinds of welding rod.

Convenient quick connection for the output makes it quick, safe, simple and stable.
