Consumable life
Consumable life varies based on the following factors:
 Thickness of the metal.
 Length of the average cut.
 Type of cutting (piercing decreases life when compared to edge cutting).
 Pierce height (stretching the arc).
 Whether you are cutting solid metal or expanded metal. Cutting expanded metal wears out consumables more
quickly. For more information, see
Cutting expanded metal on page 45.
 Hypertherm does not recommend the use of any other consumables in the Air T30 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.
Although largely dependent on the factors listed above, as a general rule, the consumables last approximately 1 to
2 hours of actual “arc on” time.
If the consumables’ life is shorter than expected or the cut quality is poor, make sure that you are using the correct
consumables and that they are properly installed. (See the following topic,
Consumable use.) Under normal conditions,
the nozzle wears out first.
 For optimal cutting performance, always replace the nozzle and the electrode together.
See Hand torch operation on page 50 for more information about proper cutting techniques.
