A., B., C. OUTPUT CONNECTORS C. HIGH INDUCTANCE NEGATIVE OUTPUT CONNECTION.

-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 CO2

shielding gas.

-The high inductance connection is more suit- able for short arc welding heavier weldments or when using 75% Argon/25% CO2 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.
