The pot that controls the level of output for the EN side of my machine only seems to adjust downward. Sometimes I can fiddle with it and get it up a bit (to 59 A max) but it usually only goes down. The others work fine. It is a 'clicking' type of pot. The welder works fine at these settings but hey, some higher highs would be better. Any thoughts on whether this problem is the pot or the board?
thanks!
