5 PLASMA CUTTING
Connect the device to a suitable power supply. (see section 2 specifications). Connect the compressed air hose to the compressed air
source. NOTE: The compressed air must be clean, oil-free and dry. Attach the Earth cable to the machine connector and the earth
clamp to the workpiece. Start the machine with the main switch. Set the switch 6 to the compressed air SET position, and adjust the
pressure with the pressure regulator to 3.5-6.0 bar. Set switch 6 to the RUN position. The machine is now ready for plasma cutting.
Ordinary cutting
Hold the torch 3-5 mm from the workpiece at an angle of about 15-30 °. This reduces the possibility of the molten metal flying
backwards to spoil the nozzles or the torch itself. Press the torch trigger. Compressed air starts to flow from the torch and the pilot arc
lights up. If the workpiece grounding to the cut circle is good, the main arc (cutting arc) will light up immediately.
After the start of the operation, when the plasma arc has pierced the workpiece completely, the torch is moved smoothly and slowly.
Using a standard nozzle, it is advisable to use a stand off guide or a short contact cutting attachment to be mounted on the torch head.
The nozzle distance to the workpiece should be 3-5 mm without the cutting support.
Note
：
If the interference light is on during operation, release the trigger until the light goes out and start cutting again.
When the front panel lever switch is in the pneumatic test position, the trigger does not work. After prolonged use, the nozzle
and cathode and other wear parts must be replaced. The protective cap must be properly seated in order to trigger to work.
Never put your hand on the torch head when the trigger is pressed! Risk of physical injury!
6 MAINTENANCE AND CARE
NOTE! Only authorized Wameta service personnel may repair and service the device. The importer will terminate the warranty
and any other liability if the machine has undergone or attempted to perform internal maintenance or repair work or changes
by others.
Cutting torch maintenance
Check the torch wear parts for wear, damage, or oxidation. Switch off the machine and replace the parts if necessary. Turn off the machine
and disconnect it from the power supply for inspection and replacement of the wear parts.
If the cutting torch has damage, defects, or wear other than wear parts, have the torch serviced by your nearest Wameta service center.
Note: A small amount of compressed air leaks between the nozzle retaining cap and the torch handle. This is normal. Do not attempt to
over-tighten the cap, parts may be damaged.
7 TROUBLESHOOTING
WARNING!
Wameta PLASMA 40 PFC is a power electronic device. There are dangerously high voltages and high currents inside
the device. Do not open the casing or attempt to perform internal repairs. There is also a dangerously high voltage in
the cutting torch. do not use a damaged torch or try to make changes to it. Use only Wameta wear parts and
nozzles. Service and repairs only by an authorized Wameta workshop.
