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.
