Operation - PROCRAFT 511468 Operating Instructions Manual

ASSEMBLY
Grounding the tool:
Attach a ground wire of at least 14 Ga. thicknesses (not
supplied) to the screw on the lower left of the back of
the tool case. Connect the other end of the wire to an
appropriate ground, such as a steel workbench, steel biding
member or grounding electrode.
Attaching the Air Supply:
WARNING: Only use dry air as the gas in this tool. Use of
any other gas, such as oxygen, acetylene, etc. may cause
explosion.
Water filter
Air input coupling
1. Attach the water filter as the above photo.
2. A male quick release adapter is mounted on the rear
of the tool. Attach your pressurized air supply using your
female quick release adapter. Adjust your air supply deliver
60-80 PSI at 3.5 CFM.
3. During operation, you can regulate air pressure through
the Plasma Cutter by adjusting the knob located on top of
the tool.
4. If the tool becomes over pressurized, there is a pressure
relief valve on the top of the unit.
1. Power Switch. Up is ON, down is OFF.
2. Power supply indicator.
3. Thermal Overload Indicator Lamp. This light will come
on, and the device will shut down if the tool becomes
overheated. Stop trying to use the cutter while leaving
the power switch onto allow the cooling fan to operate,
and the lamp will turn off automatically when the machine
cools down. Please pay attention to the Rated Duty Cycle
discussed on page 7.
4. Power Supply Controller.

OPERATION

Note: Before beginning, please read and understand all
the safety precautions staring on page 1 and especially
the section "Specific Safety Rules" starting on page 3.
1. Mount the metal to be cut to the metal weeding-cutting
table. It should be mounted so that the cutting debris falls
to the cement floor.
2. Place the Air Plasma Cutter unit no closer than six feet
from the workpicece to be cut.
3. Connect an air hose and coupling (not supplied) from
the air supply tank to the Air Input Coupling at the rear
of the unit. See photo on page 8 right. The air supply
must be regulated to between 60 and 80 PSI as read on
the Air Pressure Gauge. The air supply must be dry. It is
recommended to install a moisture filter (not included) on
the compressor. Do not use an air oiler.
4. Connect the Torch Cable plug into the twist-lock
connector on the lower left unit front. Twist to lock.
5. Plug in the Grounding Cable into the Ground Connector
on the lower right of the unit front. Twist to lock.
6. Securely place the clamping end of the Grounding Cable
Clamp to a part of the work piece or metal table that is
clean of paint, oil, or dirt. Clamp as close as possible to the
work piece without damaging the cable during cutting.
7. Verify that the Power Switch is in the Off (O) position,
then plug the 240V~line cord plug into an appropriate
240V~outlet for 511468.
8. Turn the Power Supply Controller to the desired current
(15 to 40 amps).
9. Adjust air pressure by turning the Pressure Regulator
Knob on top of the unit (see photo on page 8). Read
pressure on Pressure Gauge.
10. When everything is in place for cutting, press the Power
Switch UP to the ON position. The Power Light"
illuminate, but the Torch is not yet energized.
11. Orient yourself to one side of the area to be cut, and
move the Welding Helmet Face Shield (not included, see
page 4 item 7) over your eyes.
BE CAREFUL! PILOT PLASMA ARC CAN SEVERELY INJURE.
Once the 1. trigger is squeezed, the arc will ignite. This
unit provides a pilot arc, so the torch does not need to
contact the work piece before the cutting arc ignites.
Caution: The Torch handle is now energized. Be careful not
touch anything else with the Torch except the work piece
to be cut.
Warning: Never look at the ignited arc without the
approved, arc shaded, eye protection in a full face shield.
Permanent eye damage or blindness can occur, also Skin
burns can occur. Never breathe arc fumes.
1. Bring the Electrode (4A) of the Torch close to the staring
point of the cut. The Working Indicator Light will come on.
2. Slowly move the Torch at a slight angle along the cutting
line with the Torch tip trailing.
The air causes the molten metal to fall away from the work
piece being cut. If proper cutting is not achieved, adjust the
Power Supply Controller to a higher level, and/or increase
air flow. To increase air flow, press the Power Switch to
the Off (O) position, then adjust the air pressure at the Air
Pressure Regulator. The air will continue for a few seconds
once the trigger is released.
Note: If too much current is drawn from the Plasma
Cutter (i.e., short circuit),the Thermal Switchman overload
protector, will activate and the red Thermal Overload
Indicator Light will light. The Plasma Cutter will turn off
until it cools down. To reset you must turn the power OFF
then back ON. Press the Trigger to begin cutting again.
3. When finished cutting:
a. Release the Torch handle trigger and lift the Torch handle
from the work piece,
b. Press the Power Switch to the Off (O) position.
Set the Torch handle down on the a. metal workbench,
b. Turn the air supply off,
c. Unplug the line cord from the electrical outlet.
