I have a welder with selectors (potentiometer) to set up. What is the advantage if I install one your controllers?

Our controllers are digital while the potentiometers are analog. The evolution towards to digital allows precision and repeatability in the execution of your programs. In addition, several options allow you to go further in obtaining precise results, even for more exotic materials such as Galvalum.
