Handle – Rugged, top mounted handle
allows for easy transport of your plasma
cutter.
Power Indicator Lamp - This lamp will light
whenever Power Switch (on back of unit) is
turned to the ON position.
Pneumatic Protection Indicator Lamp -
This plasma cutter includes a pneumatic pro-
tection device, designed to prevent damage
to the unit when there is no air supply or low
air pressure on intake. Lamp will light when
pneumatic protection device intervenes.
Thermal Overload Protection Lamp - When
duty cycle has been exceeded an internal
thermal protector switch will open. This lamp
will light when thermal protection engages.
Power Cord – This is a standard 50 amp
220 volt power cord. (Make sure you are
using a properly grounded 220 Vac, 60Hz,
single phase, 25 amp power source.)
Ground Clamp – Attaching the ground
clamp to your workpiece “completes” the
electrical current circuit. You must attach the
ground clamp to the metal you are cutting. If
the ground clamp is not connected to the
metal workpiece you intend to cut, the plas-
ma cutter will not have a completed circuit
and you will be unable to cut. A poor connec-
tion at the ground clamp will waste power
and heat. Scrape away dirt, rust, scale, oil or
paint before attaching the ground clamp.
Ground Cable – The ground cable connects
the ground clamp to the internal workings of
the plasma cutter.
Cutting Torch and Cable – The cutting
torch controls the delivery of the plasma arc
to the material to be cut. Compressed air
and electricity is fed through the cable and
cutting torch when the trigger is pulled. An
electrode and cutting nozzle must be proper-
ly installed (as described later in this manual)
prior to cutting.
Power Switch – This switch turns the unit
ON and OFF. (Make sure the power switch is
in the OFF position before performing any
maintenance on the unit.)
Air Pressure Gauge - This gauge displays
the psi of air leaving the unit. To adjust the
air pressure, use the Air Pressure Regulator.
Air Pressure Regulator - Turn regulator
clockwise to increase air pressure, counter-
clockwise to decrease air pressure.
Air Inlet - Accepts threaded male coupling or
threaded male quick connector. Incoming air
should be regulated at 65 psi.
Water Trap - Check the water trap regularly.
Whenever the unit is not used for a week or
more, the compressed air should be discon-
nected completely. To drain condensation
turn the knurled nut on the bottom of the fil-
ter counter-clockwise.
