3. Turn the
Generator
and
Welder/Charger
switches on the control panel (
Figure 5-2
,
[
A
]) to their
OFF
positions.
4. Unplug any power cords that are plugged into
the generator panel.
5. Allow machine to run at idle for a 3-5 minutes
to allow for a cool down sequence.
6. Turn the
Engine Control Switch
to the
OFF
position. If no air leaks are present, the
engine should start at idle speed the next
time it is started.
5.3 ENGINE THROTTLE CONTROL
FUNCTIONS
The engine speed is controlled by three factors:
1. The level of air pressure in the tank and the
position of the pilot valve switch, if
applicable.
2. The position of the welder switch on the unit
control panel, and the use of the welder.
3. The position of the generator switch on the
control panel.
Consult Table 5A: Engine Throttle Control Function
Conditions
to understand how the engine speed relates
to the demand(s) of the machine system’s output
functions.
5.4 OPERATING THE WELDER
Consult
Figure 5-3
. The
variable power dial
adjusts the
welder amperage (30 to 205 amps), or voltage (15 to 40
volts) for the desired weld heat. Turning the power dial
clockwise increases the amperage or voltage, and
turning the power dial counterclockwise decreases the
amperage or voltage. The power dial may be adjusted
while welding.

WARNING
Before attempting any welding
procedure, the operator must be aware
of general safety practices, and
particularly those pertaining to welding,
as found in
Section 1.4
of this manual.
NOTE
The amps/volts display will read the set
value for five (5) seconds when the dial is
adjusted, and then return to the actual
output value five (5) seconds after the
dial has been adjusted.
