WIRE FEED (CONSTANT VOLTAGE) WELDING
Connect a wire feeder to the Commander 300 and set
welder controls according to the instructions listed earlier
in this section.
The Commander 300 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”.
Electrodes suitable for use are: NR-311, NS-3M, NR-207,
NR-203 Ni 1%, NR-204-H.
Electrodes suitable for use are: 0S-70, 0S-71M.
Electrodes suitable for 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 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.
ARC GOUGING
For optimal performance when arc gouging, set the
Commander 300’s “WELD MODE” switch to the “CC -
STICK” position, and the “ARC CONTROL” to 10.
Set the “OUTPUT” knob to adjust output current to the
desired level for the gouging electrode being used
according to the ratings in the following table:
* Maximum current setting is limited to the Commander
300’s maximum of 375 Amps.
PARALLELING
When paralleling machines in order to combine their
outputs, all units must be operated in th CC - STICK
mode only. To achieve this turn the WELD MODE
switch to the CC - STICK position. Operation in other
modes may produce erratic outputs, and large output
imbalances between the units.
