Plasma cut thickness checker

Compares a required cut thickness against the clean-cut and severance ratings you enter from the manufacturer’s data plate — it holds no amperage or thickness tables of its own.

Classification Entered-rating comparison

InputsT-08
F-01

Free-text label copied onto the record — it plays no part in the comparison.

F-02
mm

The thickness you need to cut, greater than 0.

F-03 Nameplate
mm

From the manufacturer’s data plate or manual, greater than 0.

F-04 Nameplate
mm

From the same data plate; at least the clean-cut rating.

F-05 Power / supply / air confirmations

Anything short of confirmed suppresses a positive comparison and stamps the record CHECK NAMEPLATE.

Worked example

STATIC — not a live result

A required thickness of 10 mm against an entered 12 mm clean-cut rating and 16 mm severance rating, with power, supply and air confirmed against manufacturer data: within the clean-cut thickness rating you entered.

Method

M.2026-09-02.1

The checker compares the required thickness only against the two ratings you entered from the manufacturer’s data plate or manual:

  • Required at or below the clean-cut rating, with power, supply and air confirmed — “Within the clean-cut thickness rating you entered”.
  • Required above the clean-cut rating but at or below severance — “Above the clean-cut rating; within the severance rating you entered”.
  • Required above the severance rating — “Exceeds the thickness ratings you entered”.
  • Confirmations not complete — the positive comparison is suppressed, the record is stamped CHECK NAMEPLATE, and manufacturer and supply confirmation is requested instead.

Worked figures: 10 mm required against an entered 12 mm clean-cut rating and 16 mm severance rating, with confirmations complete, sits within the entered clean-cut rating.

Limits & stop conditions

T-08
  • The comparison uses only the ratings you entered — no universal claim linking amperage to thickness is made or implied.
  • This comparison does not predict edge quality or finishing work. Use the machine manual, consumable data and a test cut for the actual material.
  • This tool does not model consumable condition, material-specific behaviour, travel speed or edge quality; the manufacturer’s data plate and manual govern those decisions.
  • CHECK NAMEPLATE — while power, supply and air confirmations are anything short of confirmed, no positive comparison is issued.

Equipment options

CHECK BEFORE HIRE

When the checks above are closed out, compare plasma cutter hire options from Mammoth Hire. Compare equipment only after confirming the material, clean-cut rating, severance rating, supply and air requirements against the actual manufacturer data. The entered comparison does not approve a machine.

Source register

No built-in thickness table: the record compares only the required thickness and manufacturer ratings you enter — see Methodology.
