Important Safety Information (Continued)
RISK TO EQUIPMENT: USING THE PLASMA CUTTER WITH A
PORTABLE GENERATOR
There are three common types of portable
◆
generators – brush, brushless, and inverter.
DO NOT operate this plasma cutter on a
brush type generator; voltage irregularities
may damage sensitive inverter electronics.
When powering the plasma cutter with a brushless generator,
◆
turn-off the idle-speed control. The response of an idle-speed
control is typically too slow and erratic startup of the plasma
cutter's arc will occur.
Use only a generator with a minimum of 4000 watts
◆
continuous output.
All generators will experience an engine RPM drop from
◆
suddenly applied loads. Hence, the plasma cutter will cause
a sudden drop in RPM when the torch arc is started. Engines
are typically equipped with governors that help the engine
return to normal speed under load. This usually happens
within a few seconds of when the engine senses the increased
load. To minimize the effect of this RPM drop on the plasma
cutter's arc, we recommend adding an additional 500 watt
load to the generator. This can easily be done with a halogen
light.
IMPORTANT: INTERFERENCE: H.F. RADIATION
High frequency (H.F.) radiation can
◆
interfere with radio navigation, safety
services, computers, and communications
equipment.
If notified by the FCC about interference,
◆
stop using the equipment at once and contact a qualified
electrician for assistance with the problem.
Keep covers properly installed and replace components and
◆
cables with original equipment components.
IMPORTANT: INTERFERENCE: ELECTROMAGNETIC
ENERGY
This unit can produce electromagnetic
◆
energy which can interfere with sensitive
electronic equipment such as computers
and televisions.
To reduce interference, keep cables close
◆
together and on the floor. Twisting or taping the cables
together or covering the cables with a cable cover will also
reduce interference.
Operate this unit at least 300 feet [100m] from sensitive
◆
electronic equipment.
Be sure the unit is connected to a grounded outlet.
