 Thickness of the metal you plan to cut
The amperage output setting you need to use depends on the thickness of the metal you are planning to cut and is limited
by the input power to your system. See
Voltage configurations on page 25.
Although the visual differences between the general-purpose (standard) and FineCut consumable parts
are minor, installing the wrong combination of consumables will affect the life of the parts as well as the
cut quality.
 Hypertherm does not recommend the use of any other consumables in the Duramax LT
torch except for those listed in this section, which are designed specifically for this system.
The use of any other consumables could adversely affect system performance.
Figure 1 and Figure 2 illustrate the differences between the general-purpose and FineCut nozzles and between the
deflector and the shield. The FineCut consumables have rings or grooves etched onto them (as shown in Figure 2) to
help you distinguish them from the general-purpose consumables.

Using the cut charts
The following topics provide cut charts for each set of consumables. Use these cut charts to guide you in selecting the
consumables and cutting current based on the thickness and type of the metal you need to cut.
The maximum cut speeds listed in the cut charts are the fastest possible speeds to cut metal without regard to cut quality.
Recommended cut speeds are a starting point for finding the best quality cut (best angle, least dross, and best cut
surface finish). Adjust the cutting speed for your application to obtain the desired cut quality.
When cutting thin metal – 3 mm (10 gauge) or thinner – you may achieve a higher cut quality by using the FineCut
consumables and cut charts.
