WIRE FEED (CONSTANT VOLTAGE) WELD-
ING
Connect a wire feeder to the Commander 500 and set
welder controls according to the instructions listed earlier
in this section.
The Commander 500 in the ”WIRE WELDING” position,
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 welding). Welding can be
finely tuned using the “ARC CONTROL”.
Some recommended Innershield electrodes are: NR-311,
NS-3M, NR-207, NR-203 Ni 1%, NR-204-H.
Recommended Outershield electrodes are: 0S-70, 0S-
71M.
Some recommended solid wires for MIG welding are: .035
(0.9 mm), .045 (1.1 mm) and .052 (1.3 mm), L-50 and L-
56, .035 (0.9 mm) and .045 (1.1 mm) Blue Max MIG 308
LS.
For any electrodes, including the above recommendations,
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.
The auxiliary power of the Commander consists of two
20 Amp-120VAC (5-20R) 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 12,000 watts of 60 Hz,
single phase power.The auxiliary power capacity rating
in watts is equivalent to volt-amperes at unity power
factor. The maximum permissible current of the 240
VAC output is 50 A.The 240 VAC output can be split to
provide two separate 120 VAC outputs with a maximum
permissible current of 50 A per output to two separate
120 VAC branch circuits. Output voltage is within ±
10% at all loads up to rated capacity.
NO
TE: The 120/240V receptacle has two 120V out-
puts 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 AUXIL-
IARY 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 permissible
currents shown assume that current is being drawn
from either the 120 VAC or 240 VAC supply (not both at
the same time).
