cut Quality
Maximum attainable cut quality is highly dependent on the material being cut. With the wide variety of commercial metals
and alloys being cut with plasma, optimum cut quality can vary widely from situation to situation. Suggested cut param-
eters given in this manual are starting points only for general cases. Fine tuning of the various parameters may be required
to get the best possible cut of a specific material. Some materials, including certain steels, are difficult, if not impossible to
cut dross free. Likewise, in carbon steels, variations in plate composition, treatment while rolling, contaminants and other
factors can cause the dross generated to vary from heat to heat, plate to plate and area to area on a plate. As a general rule,
using oxygen as a plasma gas produces less dross variation on carbon steel as a result of these factors, but is not a guarantee
that "dross free" cuts will be produced.

troubleshooting Guide
The following troubleshooting guide is primarily an operationally oriented guide. If a problem exists in one of the system
components, the guide will direct you to that manual. When directed to another manual, be sure a qualified maintenance
technician is contacted.
