OUTPUT PANEL CONNECTIONS

A. POSITIVE OUTPUT CONNECTION
B. LOW INDUCTANCE NEG. CONNECTION
A., B., C. OUTPUT CONNECTORS
-Each connector is a Magnum Twist-Mate™,
receptacle. Insert a mating Twist-Mate™
plug, and twist clockwise to secure.
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.
A. POSITIVE OUTPUT CONNECTION.
B. LOW INDUCTANCE NEGATIVE CONNECTION.
-The low inductance connection is typically
used for short arc welding of mild steel, par-
ticularly on thin materials or when using CO 2
shielding gas.

C. HIGH INDUCTANCE NEGATIVE OUTPUT CONNECTION.
-The high inductance connection is more suit-
able for short arc welding heavier weldments
or when using 75% Argon/25% CO 2 shield-
ing gas. This connection produces a softer
arc and a flatter bead with more wash-in than
the low inductance connection. A spray type
transfer is possible with either connection.
D. WIRE FEEDER RECEPTACLE
-14-pin MS style receptacle for wire feeder.
Provides connections for auxiliary power,
contactor closure, remote output control, wire
feeder voltmeter sense lead, and ground.
