figure 4-4a. Proper Torch Angle
H. 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 1/8" - 1/4" (3.2
mm - 6.4 mm) from the work.
I. When ending a cut, the torch switch should be released (press and release if using TRIGGER LOCK feature) and the
torch lifted off the workpiece immediately upon completion of the cut. This is to prevent the pilot arc from re-igniting
after cutting arc extinguishes and causing damage to the nozzle (double arcing).
J. 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.
