7. Adjust the Power Dial on the
welding lead to a mid-range setting
(approximately 40-50% for an 1/8”
rod).
8. Push and hold the Power Button on
the welding lead. Power will be
supplied to the welding lead and the
engine will increase speed. The
Power Button must be held down
for the duration of the weld.
9. If there is difficulty in starting the arc
due to rust or paint, push the Boost
Button momentarily for 100% power
while starting the arc. Release the
Boost Button when a stable arc is
achieved and the amperage level
will return to the Power Dial setting.
10. At any time during welding, the
weld amperage may be adjusted to
the desired level with the Power
Dial.
11. When completed with a weld,
release the Power Button. Power to
the welding lead will be turned off
and the engine will slow to idle
speed after a 30 second delay.

Figure 4-5
. The
variable power
dial
adjusts the welder amperage (0 to 150
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.
NOTE
The Power Button must be held down in
addition to the Boost Button for the
welder to function, during boost mode.
NOTE
If the customer wishes to reverse the
welding polarity, a polarity reversing
adapter is available from your local dealer.

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.
