PARALLELING

When paralleling machines in order to combine their outputs, all units must be operated in the CC-STICK mode only at the same output settings. To achieve this, turn the WELD MODE switch to the CC-STICK position. Operation in other modes may produce errat- ic outputs, and large output imbalances between the units.

The auxiliary power receptacles should only be used with three wire, four wire or fire wire earth 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.

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 weld- ing current is being drawn.

The auxiliary power of the VANTAGE® 575 CUM- MINS consists of two 15 Amp-240V single phase receptacles and one 32amp-415V 3 phase receptacle.

The auxiliary power capacity is 7,200 watts of 50 Hz, single phase power or 20,000 watts of 50Hz, three phase power. The auxiliary power capacity rating in watts is equivalent to volt-amperes at unity power fac- tor. The maximum permissible current of the 415 VAC output is 32 A.Output voltage is within ±10% at all loads up to rated capacity.

NOTE: The 240V receptacles are connected to differ- ent phases and cannot be paralleled.

SIMULTANEOUS WELDING AND AUXILIARY 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 permissi- ble currents shown assume that current is being drawn from either the 240 VAC or 415 VAC supply (not both at the same time).
