During Cutting
F. After starting the cut, the torch should be maintained at a 5-15° forward angle. This
angle is especially useful in helping to create a "drop" cut. When not using the stand-off
guide, the nozzle should be held approximately 1/4 inch (6.4mm) from the work.
G. When ending a cut, the torch switch should be released (press and release if using
trigger LOCK mode) and the torch lifted off the workpiece just before the end of the
cut. This is to prevent the high frequency from reigniting after cutting arc extinguishes
and causing damage to the nozzle (double arcing).
H. For rapid re-starts, such as grate or heavy mesh cutting, do not release the torch
switch. In the postflow mode, the arc can be re-started immediately by depressing
the torch switch. This avoids the 2-second preflow portion of the cutting cycle.
