Cut charts
The following cut charts show the consumable parts, cutting speed and the gas and torch settings required for the
specific process.
The HD4070 system will automatically select and adjust the power and gas (including amperage, gas type and gas
flow rate) required for the material and thickness to be cut.
If the Hypertherm Integrated Command THC option is installed, the HD4070 system will also automatically adjust
torch settings required for the specific process, including arc volts, torch standoff, initial pierce height and pierce
time delay.
The numbers shown in the cut charts are the HD4070’s default values and should provide high quality cuts with
minimal dross. Because of differences between installations and material composition, adjustments may be
required to obtain desirable results.

The widths in the chart below are for reference. Differences between installations and material composition may
cause actual results to vary from those shown in the table.
