Hi Guys,

I recently purchased a PowerArc 160 STH and have a small issue.

I was trying to adjust my amperage for TIG and it was not displaying any change in amperage (..yes I have the button switched to TIG.. lol), what I had to do was hold the pedal down all the way and turn the dial until I had SORTA the right amperage, lol.

How do I fix this issue?
