SETTING KERF OFFSET-
When plasma cutting, a kerf (or opening) is produced by the plasma arc. The cutting current and
feed rate as well as the diameter of the orifice in the plasma torch nozzle determine the width of
the kerf. Typically, the amount of offset will range from 0.040" (1.0 mm) to 0.060" (1.5 mm) when
cutting mild steel. If the cutting path is not modified to compensate for the kerf width, the
completed cut will be undersize (for external cuts) or oversize (for internal cuts) by the amount of
the kerf width. The machine control compensates for the kerf width without the need to redefine
the actual path. The operator must enter the desired compensation amount into the control using
the following procedure.
"Kerf Offset" can be set from Automatic Operation Menu, Press "AUTO [F1]" Button.
Press the "KERF Button".
