2. Torch-to-work distance is not correct (check Cut Chart information).
3. Cutting speed is not correct (check Cut Chart information).
4. Arc current is not correct (check Cut Chart information).
5. Damaged consumable parts (see Changing Consumable Parts ).
• Short consumable life. Causes can be:
1. Arc current, arc voltage, travel speed, motion delay, gas flow rates, or initial torch height not set as
specified in Cut Charts.
2. Attempting to cut highly magnetic metal plate (some metals such as armor plate with a high nickel
content) will shorten consumable life. Long consumable life is difficult to achieve when cutting plate that
is magnetized or becomes magnetized easily. Call Hypertherm's Technical Service (1-800-643-9878) if
you suspect the type of metal you are cutting is causing shortened consumable life.
3. Not beginning or ending cut on plate.
Also see Cutting Techniques later in this section for methods to improve cutting performance.

Cut Charts
The Cut Charts on the following pages provide the necessary information in order for the operator using the
system to be successful in plasma arc cutting. The HT2000 provides a wide travel speed operating window:
usually ± 10 ipm (± 254mm/min) on most materials. The data listed in the charts are for making drop cuts with
minimal dross.
Caution: Before cutting, check all settings and adjustments and check for damaged torch
parts and worn consumable parts.
