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

RANGER 305D
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 outlet 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 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.
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.

* 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.

SIMULTANEOUS WELDING AND
AUXILIARY POWER LOADS
The above 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).
