B-10 OPERATION B-10
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.
