OPERATION
Operating Data (Cut) Charts
The Cut Charts on the following pages are optimized to provide the best cut angle, least dross and best cut surface
finish. Keep in mind that these charts provide a good starting point and that optimum cutting must be tuned to the
application and materials on site. Increasing cut speed, lowering the torch standoff, higher current consumables on
thinner metals or increasing the oxygen ratio in the shield mix, for example, all present certain tradeoffs as
mentioned in How to Get Better Cut Quality. Depending on the cutting application, it is up to the operator to
determine if the tradeoffs are acceptable.
The cut chart also provides part numbers and illustrations of the consumables required to cut at a specific
amperage. For more detailed information, refer to the gas console control and indicator descriptions and the daily
operating procedure at the front of this section.
