OPERATION
SAE-300 ® MP
a.
When welding or drawing power for lights or tools (approxi-
mately 100 watts minimum) from the receptacles, the idler
solenoid deactivates and the engine operates at high idle
speed.
b.
When welding ceases or the power load is turned off, a pre-
set time delay of about 15 seconds starts. This time delay
cannot be adjusted.
c.
If the welding or power load is not re-started before the end
of the time delay, the idler solenoid activates and reduces
the engine to low idle speed.
AUXILIARY POWER
If GFCI is tripped, See the MAINTENANCE section for detailed
information on testing and resetting the GFCI.
The AC auxiliary power, supplied as a standard, has a rating of
3.0 KVA of 120/240 VAC (60 hertz). Set fine current adjustment
at 100 for maximum auxiliary power.
With the 3.0 KVA, 120/240 VAC auxiliary power, one 120V duplex
protected by GFCI and one 240V duplex, grounding type recepta-
cle with 2 pole, 15 amp circuit breaker.
The rating of 3.0 KVA permits a maximum continuous current of
13 amps to be drawn from the 240V duplex receptacle. 20 amps
can be drawn from the 120V duplex receptacle. The total com-
bined load of all receptacles is not to exceed 3.0 KVA.
An optional power plug kit is available. When this kit is specified,
the customer is supplied with a plug for each receptacle.
IDLER OPERATION
Start the engine with the “Idler” switch in the “High” position.
Allow it to run at high idle speed for several minutes to warm the
engine. See Specifications for operating speeds.
The idler is controlled by the “Idler” toggle switch on the welder
control panel. The switch has two positions as follows:
1.
In the “High” position, the idler solenoid deactivates,
and the engine goes to high idle speed. The speed is con-
trolled by the governor.
2.
In the “Auto” / position, the idler operates as fol-
lows:

GAS-SHIELDED FLUX-CORED WELDING
Start by setting the Wire (CV) / Stick (CC) toggle switch to the Wire (CV)
position. Then set the left-side Coarse Current control dial to 220. Now
move the Voltage Adjustment dial to the desired voltage. Move the Coarse
Current control to the left for a softer arc and to the right for a crisper arc.
MIG WELDING
Start by setting the Wire (CV) / Stick (CC) toggle switch to the Wire (CV)
position. Then set the left-side Coarse Current control dial to 220. Now
move the Voltage Adjustment dial to the desired voltage. Move the Coarse
Current control to the left for a softer arc and to the right for a crisper arc.
CARBON ARC GOUGING
Set both the Coarse Current and Fine Current O.C.V controls to maxi-
mum for carbon arc gouging in the CC (constant current) mode. If the
CV (constant voltage) mode is desired, set the Wire (CV) / Stick (CC) tog-
gle switch to the Wire (CV) position. Then set the left-side Coarse
Current control to 270 and the Voltage Adjustment dial to maximum out-
put.
