Simultaneous Welding And Auxiliary Power Loads - Lincoln Electric Ranger 305D Service Manual

B-9
The 240 VAC receptacle can be split to provide two
separate120 VAC outputs with a maximum permissible
current of 42 amps pea, 40 amps continuous per out-
let to two separate 20 amp branch circuits. (These cir-
cuits 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. For extension cord lengths, see Table B.5.

* Each 120 VAC leg of the 120/240 VAC Full KVA receptacle can deliver a maximum
40 amps, up to a total of 80 amps at 9500 Watts, 60 amps at 7100 Watts, or 46
amps at 5600 Watts. These outputs cannot be paralleled, so the greatest single
120 VAC load is 40 amps.
Each 120 VAC Duplex receptacle is limited to 20 amps maximum.

NOTE: The 240 VAC receptacle has two circuits, each
of which measure 120 VAC to neutral. However, they
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 spec-
ified 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).
