Software notes This welder does not rely on any external control software or require cloud connectivity. The interface is based on direct manual controls via potentiometers, complemented by two digital displays that show preset voltage and wire feed speed during setup, as well as actual values during welding. The lack of complex IT management makes it a purely analog product that is straightforward to operate in the field.
