Hypertherm Powermax85 cut chart: cutting speeds and pierce delays by thickness

The values below come from the Powermax65/85 Operator Manual 806650 rev 4: for each thickness, the chart's best-quality speed and pierce delay at the highest amperage the chart lists for it, on oxygen for mild steel and on nitrogen for stainless and aluminium where the system offers them. The inch table is the chart's own, not a conversion.

These are the maker's figures for a new, well-set machine at its recommended settings. Your machine may cut slower with worn consumables, or faster when the edge allows it. A starting point, not a quote.

In Nest&Quote a machine's speed table is filled from this chart in one click, each row with its source, for you to check and correct. The cut time and the price then come from your own rows, and real run times adjust the rest.
