Cut charts - Plasma Automation

OPERATION

Cut charts

The following Cut charts show the consumable parts, cutting speeds and the gas and torch settings required for each process.

The numbers shown in the Cut charts are recommended to provide high-quality cuts with minimal dross. Because of differences between installations and material composition, adjustments may be required to obtain desired results.

Bevel cutting

See Appendix C in this manual for cut charts and consumables.

Marking

Any of the consumable sets can also be used for marking. Marking parameters are shown at the bottom of each cut chart. The quality of the markings will vary depending on the cut process, material type, and material thickness combination. Marking is not possible for every combination (very thin materials). Poor quality marking or burn-through may occur with material less than 1.5 mm (0.060 in or 16 gauge).

Consumables for mirror-image cutting

See the Parts List section in this manual for part numbers.
