SECTION 3
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.
