1. With the engine shut off, insert the twist
lock connection of the ground clamp
into the negative (-) welder connection
port on the control panel. Insert the
power lead segment from the suitcase
feeder into the positive (+) welder
connection port on the control panel.
2. Place the ground clamp from the
suitcase feeder and the ground clamp
from the Air N Arc
I
-300 on the work
piece.
3. Start the engine (
See Section 4.2,
Machine Start-up and Shutdown
Procedure
).
4. On the control panel, place the DC
Charger/Welder switch in welder
mode. Place the CC/CV switch in CV
mode.
5. Adjust the power dial on the Air N Arc
I
-300 to the appropriate voltage
setting for the material being welded.
Adjust the power dial on the suitcase
feeder for the material being welded. At
anytime during welding, the power dial
may be adjusted to the desired voltage
level.
4.5 OPERATING THE
GENERATOR
To operate the generator:
1. Start the engine.
2. With the engine warmed up and
operating at low idle, turn the generator
switch on the control panel to the
ON
position.
Combined
output
on
all
generator
receptacles is limited to the total rated
generator capacity. For example; if 1,500
watts (12.5 amps) is being drawn on the
120V duplex receptacle, only 3,700 watts
(15.5 amps) is available at the 240V
receptacle. Check the desired power tool,
motor or extension cord manufacturer’s
specifications for general information on the
power requirements of common power tools,
motors and extension cords in order to
confirm power draw limitations.
If the thermal overload circuit breakers on
the generator are tripped due to an overload
condition, press the white reset buttons on
the generator panel to reset the breakers
(
Figure 4-5
).
NOTE
When using a spool gun, an adapter with
contactor must be used. Please consult
the spool gun manufacturer for
appropriate adapter.
WARNING
DO NOT rely on the thermal overload
circuit breakers on the generator to
protect personnel, power tools, or the
generator. The thermal overload circuit
breakers on the generator require time to
overheat when the generator is operating
in an overload condition — they DO NOT
provide instant protection against short
circuiting or overload conditions. Always
use GFCI protected extension cords and
power strips when using the generator.
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.
IMPORTANT
Only plug power cords into the generator
receptacles AFTER the engine is running
at full speed.
Be careful not to overload the rated
capacity of the generator - 6,800 watts
(28 amps @ 240V) continuous.
WARNING
If one of the generator circuit breakers is
tripped, the cause of the overload must
be determined before the circuit breaker
is reset and work is resumed.
