Bevel compensation tables
Hypertherm’s TrueBevel™ software has specialized cut charts known as “bevel compensation 
tables.” They can help you get the best results on mild steel with minimal operator intervention.
For information about how to access and use the bevel compensation 
tables, refer to the instruction manual that came with your Hypertherm 
CAM software.
Hypertherm’s ProNest
TM
 software includes bevel-compensation tables.
For information about CNC compatibility requirements and how to use 
bevel compensation tables with non-Hypertherm CNCs, contact your 
cutting machine supplier or regional Hypertherm Technical Service team.
Ferrous (mild steel) processes
Ferrous (mild steel) processes are developed for cutting A36 mild steel. All mild steel processes are 
available with all 3 XPR gas connect consoles (OptiMix, VWI, and Core). Mild steel processes use 
O
2
/Air in most cases, except for the following:
 Lower-current cutting processes on thinner metals, True Hole, and internal-feature cutting 
use O
2
/O
2
.
 The 300 A processes, on some thicknesses, use O
2
/N
2
.
 Argon-assist technology uses argon (Ar) in the shield to increase pierce capacity.
Refer to the XPR Cut Charts Instruction Manual (809830) for information 
about the gases used for plasma gas and shield gas during different 
processes.
All mild steel processes use Hypertherm’s enhanced LongLife
® 
technology that works together with 
Arc Response Technology™ to extend the life of consumables by detecting and reacting to 
rampdown errors before they occur.
The consumable parts for 300 A processes are non-vented and use a 
liquid-cooled nozzle (in place of a vented, air-cooled nozzle).
HyDefinition vented 
processes
The XPR300 cutting system offers HyDefinition vented consumables for 30 A – 170 A 
processes. The processes enable the operator to achieve the following results:
• High-quality cuts
• Dross-free cutting (metal dependent)
• Fast cut speeds
HyDefinition 220 A 
and 300 A processes
The 220 A and 300 A processes are non-vented and deliver the following cutting options:
• High-quality cuts
• Excellent consumable part life
• Dross-free cutting with most thicknesses (metal dependent)
• Consistent cut quality over the lifetime of the consumable parts
