9. WIRE FEEDER VOLTMETER SWITCH

This switch selects the polarity of the wire feeder voltmeter, if so equipped. 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.

+Output connector is a Magnum Twist-Mate™, receptacle. Insert a mating Twist-Mate™ plug, and twist clockwise to secure.

11.LOW INDUCTANCE NEGATIVE CONNECTION.

Output connector 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.

Output connector is a Magnum Twist-Mate™, receptacle. 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% CO2 shielding 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.

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 voltmeter sense lead, and ground.
