WIRE FEED (CONSTANT VOLTAGE)
WELDING
Stick and Wire models only. Connect a wire feeder to
the Commander 400 (see the Accessories section)
and set the welder controls according to the instruc-
tions in “Controls and Settings” in this section of the
manual.
The Stick and Wire model of the Commander 400, with
its CV tap, permits it to be used with a broad range of
flux cored wire (inner shield and Outer shield) elec-
trodes and solid wires for MIG (GMAW).
For any electrodes, the procedures should be kept
within the rating of this machine. For additional elec-
trode information, see Lincoln publications N-675, GS-
100 and GS-210.
AUXILIARY POWER
Be sure that any electrical equipment plugged into the
generator AC power receptacles can withstand a ±10%
voltage and a ±3% frequency variation.
The Commander 400 can produce 10,000 watts of 60
Hz, single-phase auxiliary power. (The rating in watts
is equivalent to volt-amperes at unity power factor.)
The output voltage is within ±10% at all loads up to the
rated capacity.
The following receptacles are provided:
• Two 15 amp-120VAC duplex FGCI receptacles
(5-15R)
• One 50 amp-120/240VAC receptacle (14-50R)
The 50 amp receptacle has a maximum permissible
output of 44 amps. However, it can be split to power
two separate, single-phase 120VAC branch circuits
each capable of 44 amps output.
NOTE: The two 120VAC outlets of the 120/240VAC
receptacle cannot be paralleled. They are on two dif-
ferent phases.
The auxiliary power receptacles should be used with
only three-wire, grounded type plugs or approved dou-
ble-insulated tools with two-wire plugs. The current rat-
ing of any plug used with the system must be at least
equal to the current-carrying capacity of the associated
receptacle. An optional power plug kit is available.
See the Accessories section.
SIMULTANEOUS WELDING AND AUXIL-
IARY POWER LOADS
The auxiliary power ratings above are with no welding
load. Simultaneous welding and power loads are spec-
ified 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).
