must be set lower.

7. Start cutting slowly and then increase the speed in order to achieve the desired cutting quality.
8. The speed must be regulated so that a good cutting capacity can be achieved.
9. When the cutting work is complete push the interlocking switch
PLEASE NOTE: To cut in manual cutting mode, pull the overlying burner across the workpiece
while maintaining a constant speed. To achieve the perfect cut, it is important for the material thickness
to comply with the correct cutting speed. If the cutting speed is too low, the cutting edge will be blunt
due to the severe heat input. The optimal cutting speed is achieved once the cutting jet is slightly inclined
towards the rear while cutting. If the plasma burner button is released
the power supply switches off. The gas continues to flow for approx. 5 seconds in order to cool the
burner. During the gas post-flow time, the plasma cutter

ATTENTION: The device must be left on for approx. 2–3 minutes once the cutting work has been
completed. The cooler cools the electronics.

The output voltage will be lowered to zero.
After the device has cooled down (approx. 10 minutes) you can resume work.
If you press the burner button and the electrical contact is not good, the hazard reduction device (HRD)
will inhibit the voltage output. The overheating protection and HRD display

This working method is called drag cutting. Avoid quick movements. A sign of quick movements is
sparks that fall off the top of the workpiece. Move the plasma burner
accumulation is concentrated on the bottom side of the workpiece. Ensure the material is completely
separated prior to continuing with this process. Set the necessary drag speed.
Distance cutting
In some case, it is beneficial cut while holding the burner sleeve
above the workpiece. This reduces the quantity of material that is blown back into the tip. This makes it
possible to penetrate thicker material thicknesses. Distance cutting should be used if penetration or
furrow work is carried out. Furthermore, the "distance" working technique can be used when you need
to cut sheet metal to minimise the risk of material splashing back which could damage the tip.
Perforation
To drill through place the tip approx. 3 mm above the workpiece. Hold the plasma burner
