WIRE FEED (CONSTANT VOLTAGE)
WELDING
Connect a wire feeder to the Commander 300 and set
welder controls according to the instructions listed ear-
lier in this section.
The Commander 300 in the "WIRE WELDING" posi-
tion, permits it to be used with a broad range of flux
cored wire (Innershield and Outershield) electrodes
and solid wires for MIG welding (gas metal arc weld-
ing). Welding can be finely tuned using the "ARC CON-
TROL."
Some recommended Innershield electrodes are NR-
311, NS-3M, NR-207, NR-203 Ni 1%, NR-204-H.
Recommended Outershield electrodes are 0S-70,
0S71M.
Some recommended solid wires for MIG welding
are.035 (0.9 mm), .045 (1.1 mm) and .052 (1.3 mm), L-
50 and L56, .035 (0.9 mm) and .045 (1.1 mm) Blue
Max MIG 308 LS.
For any electrodes, including the above recommenda-
tions, the procedures should be kept within the rating of
the machine. For additional electrode information, see
Lincoln publications N-675, GS-100 and GS-210.

AUXILIARY POWER OPERATION

Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings, if no welding
current is being drawn.

COMMANDER 300
The auxiliary power of the Commander 300 consists of
two 15 Amp-120 VAC (5-15R) duplex receptacles and
one 50 Amp-120/240 VAC (14-50R) receptacle. The
120/240VAC receptacle can be split for single-phase
120 VAC operation.
The auxiliary power capacity is 10,000 watts of 60 Hz,
single-phase power. The auxiliary power capacity rat-
ing in watts is equivalent to volt-amperes at unity power
factor. The maximum permissible current of the 240
VAC output is 44 A. The 240 VAC output can be split to
provide two separate 120 VAC outputs with a maxi-
mum permissible current of 44 A per output to two sep-
arate 120 VAC branch circuits. Output voltage is with-
in + 10% at all loads up to rated capacity.
NOTE: The 120/240V receptacle has two 120V outputs
of different phases and cannot be paralleled.
The auxiliary power receptacles should only be used
with three-wire, grounded type plugs or approved dou-
ble-insulated tools with two-wire plugs.
The current rating of any plug used with the system
must be at least equal to the current capacity of the
associated receptacle.
SIMULTANEOUS WELDING AND
AUXILIARY POWER LOADS
It must be noted that the above auxiliary power ratings
are with no welding load. Simultaneous welding and
power loads are specified in table B.4. The permissi-
ble currents shown assume that current is being drawn
from either the 120 VAC or 240 VAC supply (not both
at the same time).
