Controls look similar to a Miller Syncrowave. Get a manual for that machine. Look for an older Syncrowave 350.
contactor = remote for a foot pedal or finger tip switch.
Weld current = local, or remote if using a foot pedal or finger tip control.
crater fill = OFF
spot time = OFF
start current = OFF
preflow = set to 1
post flow = set to 5 - 10 or to keep tungsten clean.
ac balance = full CW for max penetration ( clean your work piece first) or start at 50/50
pulsar = off, ignore the rest of those controls.
high freq = ON Continuous ( always continuous for AC TIG )
Big switch set to AC
range = high
amps = 150
That should get you started.
