OPERATION
Return to Section TOC
The 240 VAC output can be split to provide two sepa- rate 120 VAC outputs with a maximum permissible cur- rent of 33 amps per output to two separate 20 amp branch circuits. (These circuits cannot be paralleled.) Output voltage is within ±10% at all loads up to rated capacity.
The 120 VAC auxiliary power receptacles should only be used with
NOTE: The 240 VAC receptacle has two circuits, each of which measures 120 VAC to neutral. However, they are of opposite polarity and cannot be paralleled.
SIMULTANEOUS WELDING AND AUXILIARY POWER LOADS
The 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).
