3 – Torch Setup
Consumable life
Consumable life varies based on the following factors:
Thickness of the metal
Length of the average cut
Gas supply quality (presence of oil, moisture, or other contaminants)
Type of cutting (piercing decreases life when compared to edge cutting)
Pierce height
Consumables (FineCut or general-purpose)
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.
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, verify that you are using the correct combination
of consumables. (See the following topic, Choose the consumables.) Under normal conditions, the nozzle wears out first.
See Hand torch operation on page 48 for more information about proper cutting techniques.
Choose the consumables
The Duramax LT hand torch ships with general-purpose consumables installed. The general-purpose consumables are
designed for a broad range of cutting applications.
Also included with your system is at least one FineCut nozzle and deflector. The FineCut consumables are designed to
achieve more finely detailed results on thin gauge metal.
The retaining cap, swirl ring, and electrode are the same for both sets of consumables.
The consumables that you choose should be determined by the:
Input power
Amperage output setting
Thickness of the metal you plan to cut
WARNING!
INSTANT-ON TORCHES
PLASMA ARC CAN CAUSE INJURY AND BURNS
The plasma arc ignites immediately when you press the torch trigger. Make
sure the power is OFF before changing consumables.
