No such option here...fully auto on the PI! Self senseing even down to polarity so now need to swith the pos and neg around on the front of the set! I have been spoiled.
Most new ,decent, TIG sets are fully auto now. Tried the Kempiis aswell but price has alot to do with most purchases i beliveve.
Some ggod second hand, read repossed, plant around at the mo. Try some of the online plant sales auctions.
