ARC GOUGING

The RANGER 305G can be used for limited arc goug- ing. For optimal performance, set the MODE switch to CC-STICK and the ARC CONTROL to +10.

Set the CONTROL knob to adjust output current to the desired level for the gouging electrode being used according to the ratings in the following table.

AUXILIARY POWER:

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

The auxiliary power of the RANGER 305G consists of two 20 Amp-120 VAC (5-20R) duplex receptacles and one 50 Amp 120/240 VAC (14-50R) receptacle. The 240 VAC receptacle can be split for single phase 120 VAC operation.

The auxiliary power capacity is 10,000 watts Peak, 9500 Watts continuous of 60 Hz, single phase power. The auxiliary power capacity rating in watts is equiva- lent to volt-amperes at unity power factor. The max permissible current of the 240 VAC output is 40 Amps.

The 240 VAC output can be split to provide two sepa- rate 120 VAC outputs with a max permissible current of 40 Amps per output to two separate 120 VAC branch circuits (these circuits cannot be paralleled). Output voltage is within ± 10% at all loads up to rated capacity.

The 120 V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double 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.

NOTE: The 240 V receptacle has two circuits, each of which measure 120 V to neutral but are of opposite polarities and cannot be paralleled.

Simultaneous Welding and Auxiliary Power Loads The above auxiliary power ratings are with no welding load. Simultaneous welding and power loads are specified in the following table. The permissible cur- rents shown assume that current is being drawn from either the 120 VAC or 240 VAC supply (not both at the same time).
