For this mode it may be convenient to use the dual button torch option or dual button with potentiometer. The «up» command keeps the same func-
tion as the single button or trigger torch. The «down» button can, when pressed, switch to the cold current. The potentiometer of the torch, where
available, allows control of the welding current from 50% to 100% of the value displayed.
