7.5 Cutting
1 Start the cutting process at the edge
of the workpiece.
2 Do not move the cutting torch until
the material has been cut through
completely.
3 Place the cutting torch upright on the
edge of the workpiece.
4 Pull the cutting torch in the cutting
direction. Sparks must emerge from
the underside of the workpiece.
5 Pay attention to the following when
cutting:
 Hold the cutting torch vertically and
observe the arc while cutting.
 Make light contact between the
shield and the workpiece and pull
the cutting torch in the cutting
direction at a constant speed.
 For cutting thin workpieces, reduce
output current strength to a
minimum to achieve the highest
cutting quality.
 For cutting straight lines/bevels, use
a straight edge as a guide.
 For cutting circles, use a template or
circle cutting device.
If sparks escape upwards during
cutting, the material has not yet been
completely severed. Proceed as
follows:
 Reduce the speed at which the
cutting torch is pulled.
 Check the setting for the output
current.
 Check the compressed air settings.
 Check consumables for
wear/damage.
