3. Select the appropriate electrode for
the material and process being
performed. See
Table 4B
for
selecting an electrode.
4. Place the ground clamp on the
work piece and insert the
appropriate welding rod into the
electrode clamp.
5. Start the engine (See
Section 4.2,
Engine Startup and Shutdown
Procedure
).
6. Turn the Welder switch on the
control panel to the
ON
position.
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.
4.5 OPERATING THE
GENERATOR
To operate the generator:
1. Start the engine.
2. Turn the Generator switch on the
control panel to the
ON
position.
For general information on the power
requirements of common power tools,
motors and extension cords, check the
desired power tool, motor or extension cord
manufacturer’s specifications.
NOTE
If a longer welding lead is desired,
optional 50 ft. lead segments may be
purchased from your local dealer for a
maximum lead length of 100 ft.
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.
NOTE
Only plug power cords into the generator
receptacles AFTER the engine is running
at full speed.
IMPORTANT
The Power System is designed to
support a multi-function project.
However, if the generator is operating at
a high percentage of its rated capacity,
and the welder and air compressor are
also being used, the resulting drop in
engine speed may produce a low voltage
condition that will damage the generator
and power tools being used.
NOTE
Be careful not to overload the rated
capacity of the generator - 4,200 watts
(17.5 amps @ 240V or 17.5 amps @ 120V
for each outlet) continuous.
