Working with the plasma cutting device
ATTENTION:
Always wear protective clothing when working and make sure that other persons in the area
are not put at risk by the UV radiation of the arc.
Never touch the front part of the torch (nozzle, electrode, outer guard).
➜
The cut is made by positioning the nozzle to within 2 mm - 3 mm of the workpiece to be cut. Keep the torch
tilted so that the molten metal cannot get onto the nozzle when the cutting arc is ignited. When the button is
pressed, the ignition arc jumps onto the workpiece. Slowly aim the torch until the workpiece is perforated
and then make the cut.
➜
To start the cut for material thicknesses greater than 2 mm or 3 mm, perforate the material with another tool,
e.g. by drilling or by starting at the edge of the workpiece. For smaller material thicknesses, it is possible to
start in full material using the inclined torch technique.
➜
Maintain a medium, steady speed during the cut. Use a leading angle of 5° - 15° in the cutting direction.
Figure 6-4 point 3 gives the results of an incorrect cutting speed.
