Lincoln Electric IM672 RED-D-ARC ZR-8 - Manual (Page 21)

– 20 –
Auxiliary Power
The ZR-8 can provide up to 8,000 watts of 115/230
volts AC, single phase 60Hz power for continuous
use. The front of the machine includes three recepta-
cles for connecting the AC power plugs; one 50 amp
115/230 volt NEMA 14-50R receptacle and two 20
amp 115 volt NEMA 5-20R receptacles.
Do not connect any plugs that connect to the power
receptacles in parallel.
------------------------------------------------------------------------
Start the engine and set the “IDLER” control switch to
the desired operating mode. Set the “CONTROL” to
10. Voltage is now correct at the receptacles for aux-
iliary power.
115/230 Volt Dual Voltage Receptacle
The 115/230 volt receptacle can supply up to 35
amps of 230 volt power to a two wire circuit, up to 35
amps of 115 volts power from each side of a three
wire circuit (up to 70 amps total). Do not connect the
115 volt circuits in parallel. Current sensing for the
automatic idle feature is only in one leg of the three
wire circuit as shown below.
115 V Duplex Receptacles
The 115V 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 load through the
associated receptacle (Refer to Tables I and II). Do
not attempt to connect power receptacles in parallel.
Motor Starting
Most 1.5 hp AC single phase motors can be started if
there is no load on the motor or other load connected
to the machine, since the full load current rating of a
1.5 hp motor is approximately 20 amperes (10
amperes for 230 volt motors). The motor may be run
at full load when plugged into only one side of the
duplex receptacle. Larger motors through 2 hp can
be run provided the receptacle rating as previously
stated is not exceeded. This may necessitate 230V
operation only.
