9. WIRE FEEDER VOLTMETER SWITCH
This switch selects the polarity of the WORK sens-
ing lead (#21) to the wire feeder. When welding
electrode positive, (MIG, Outershield and some
Innershield processes), set the switch to "+".
When
welding
electrode
negative,
(most
Innershield electrodes), set the switch to "-".
This switch has no effect on the welding polarity.
In fact, if the wire feeder being used does not have
a voltmeter, the setting of this switch has no effect.
10. POSITIVE OUTPUT CONNECTION.
The Positive (+) Output Connector is a Magnum
Twist-Mate™, receptacle. Insert a mating Twist-
Mate™ plug, and twist clockwise to secure.
11. LOW INDUCTANCE NEGATIVE CONNECTION.
The Low InductanceOutput con-
nector is a Magnum Twist-Mate™,
receptacle. Insert a mating Twist-
Mate™ plug, and twist clockwise to
secure.
The low inductance connection is typically used
for short arc welding of mild steel, particularly on
thin materials or when using CO2 shielding gas.
12. HIGH INDUCTANCE NEGATIVE OUTPUT CONNECTION.
The High Inductance Output connec-
tor is a Magnum Twist-Mate™, recep-
tacle. Insert a mating Twist-Mate™
plug, and twist clockwise to secure.
The high inductance connection is more suitable
for short arc welding heavier weldments or when
using 75% Argon/25% CO
2
shielding gas. This
connection produces a softer arc and a flatter bead
with more wash-in than the low inductance con-
nection.
A spray type transfer is possible with
either connection.
Note: For
GMAW
processes,
and
most
FCAW
processes, the positive output connection goes
to the wire feeder. One of the negative output
connections goes directly to the work.
13. WIRE FEEDER RECEPTACLE
14-pin MS style receptacle for wire feeder.
Provides connections for auxiliary power, contac-
tor closure, remote output control, wire feeder
WORK sense lead, and ground.
