/ (HIGH IDLE/RUN)
, the engine runs at the high idle
position, the idler operates as
a. When switched from "High" to "Auto" or after starting the
engine, the engine will operate at full speed for approximately
12 seconds and then go to low idle speed.
b. When the electrode touches the work or power is drawn for
lights or tools (approximately 100 Watts minimum) the engine
accelerates and operates at full speed.
c. When welding ceases and the AC power load is turned off, a
fixed time delay of approximately 12 seconds starts.
d. If the welding or AC power load is not restarted before the end
of the time delay, the idler reduces the engine speed to low
idle speed.
