* For pipe cutting, substitute "workpiece thickness" with "wall thickness" to calculate the effective thickness.
1 Effective thickness
2 Angle of the torch – sin(a)
3 Wall thickness
The table below shows how effective thickness changes with different torch angles.
Effective thickness
12 mm (.50 inch)
17 mm (.71 inch)
25.4 mm (1.00 inch)
You can calculate the effective thickness for any thickness and torch-angle combination with the
following formula:
Hypertherm recommends that you use the thickness settings in the cut chart that are most similar to
the effective thickness that you want to cut. After cutting starts, adjust thickness settings only as
necessary.
