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 120 volt

power cord. (Make sure you are using a

properly grounded 120 Vac, 60Hz, single

phase, 20 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.
