Thank you Len The one im having the most difficulty with is the switch with 3 functions..... Has a line, a tight wave and a bigger longer wave. I think... Straight is sign wave? Tight wave and long wave a for square wave settings? With the longer wave being for greater cleaning function? Im really n...

Im not after a specific setting.
Just want to know what the dials and switchs control? There was a manual but it was for safety only and not about the machine settings unfortunately.....

Can anyone help with explaining the controls and what there for on my 200amp ac/dc pulse tig....have googled but not it's helping.... I can weld ok both ac and dc but setting it up is more trial and error than knowing
