WIRE FEED (CONSTANT VOLTAGE) WELD- ING

Connect a wire feeder to the Commander 500 and set welder controls according to the instructions listed earlier in this section.

The Commander 500 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”.

Some recommended Innershield electrodes are: NR-311, NS-3M, NR-207, NR-203 Ni 1%, NR-204-H.

Recommended Outershield electrodes are: 0S-70, 0S- 71M.

Some recommended solid 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 recommendations, 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.

AUXILIARY POWER OPERATION

Start the engine and set the IDLER control switch to the desired operating mode. Full power is available regardless of the welding control settings, if no welding current is being drawn.

The auxiliary power of the Commander consists of two 20 Amp-120VAC (5-20R) duplex receptacles and one

50Amp-120/240 VAC (14-50R) receptacle. The 120/240VAC receptacle can be split for single phase

120VAC operation.

The auxiliary power capacity is 12,000 watts of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equivalent to volt-amperes at unity power factor. The maximum permissible current of the 240 VAC output is 50 A. The 240 VAC output can be split to provide two separate 120 VAC outputs with a maximum permissible current of 50 A per output to two separate 120 VAC branch circuits. Output voltage is within ± 10% at all loads up to rated capacity.

NOTE: The 120/240V receptacle has two 120V out- puts of different phases and cannot be paralleled.

The auxiliary power receptacles should only be used with three wire grounded type plugs or approved dou- ble insulated tools with two wire plugs.

The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.

SIMULTANEOUS WELDING AND AUXIL- IARY POWER LOADS

It must be noted that the above auxiliary power ratings are with no welding load. Simultaneous welding and power loads are specified in table B.4. The permissible currents shown assume that current is being drawn from either the 120 VAC or 240 VAC supply (not both at the same time).
