ENGINE CONTROLS
1. STOP / (LOW IDLE/RUN) / (HIGH IDLE/RUN)
SWITCH
Toggling the switch to the RUN position energizes the fuel sole-
noid for approximately 30 seconds. The engine must be started
within that time or the fuel solenoid will degenerize, and the
switch must be toggled to reset the timer.
Has two positions as follows:
1) In the “High” position , the engine runs at the high idle
speed controlled by the governor.
2) In the “Auto” / position, the idler operates as
follows:
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.
e. The engine will automatically return to high idle speed when the
welding load or A.C. power load is reapplied.
