5-5. Connecting 120 Volt Input Power
! Installation must meet all National and
Local Codes − have only qualified
persons make this installation.
! Special installation may be required
where gasoline or volatile liquids are
present − see NEC Article 511 or CEC Sec-
tion 20.
For 120 volts AC input power, a 15 or 20 ampere
individual branch circuit protected by time-delay
fuses or circuit breaker is required.

5-6. Generator Or Inverter Requirements
 Generator or inverter operation varies by manufacturer. The power light on the cutter will flash and the unit will not provide output if input voltage
drops below 92 volts AC (see Section 7-2).
Minimum auxiliary power require-
ment at rated cutting capacity [1/8
in. (3.2 mm) mild steel] is 4 KW con-
tinuous/4.5 KW peak at 120 volts
AC.
 The 120 volts AC output of a
brushless generator will momen-
tarily droop when loaded. This
may result in arc outages at the
cutter. Connecting a load, such
as a 500 watt halogen light bulb,
to the 120 volts AC generator
circuit will pre-load the circuit and
may result in less generator
output droop and better cutting
performance.
 For inverter operation, a 200
ampere alternator is recom-
mended for adequate recharg-
ing of the vehicle battery.
! Engine Control Switch must be set at “RUN”
position − not “RUN/IDLE”.
! Set generator Fine Adjustment Control
to 10 for maximum auxiliary power.
