AUXILIARY POWER

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

The auxiliary power of the Ranger 275 consists of two 15 Amp-120VAC (5-15R) duplex receptacles and one 50 Amp 120/240 VAC (14-50R) receptacle.

The auxiliary power capacity is 9,000 watts of 60 Hz, single phase power. The auxiliary power capacity rat- ing in watts is equivalent to volt-amperes at unity power factor. The max permissible current of the 240 VAC output is 38 Amps. The 240 VAC output can be split to provide two separate 120 VAC outputs with a max permissible current of 38 Amps per output to two separate 120 VAC branch circuits. Output voltage is within Å 10% at all loads up to rated capacity.

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

SIMULTANEOUS WELDING AND 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 the following table. 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).
