Purge Time
Specifies the time delay from torch ignition until motion is enabled if Arc On Feedback is OFF.
Purge time should be set to Zero if Arc On Feedback is ON.
Pierce Time
Specifies the time delay from when torch completes lowering until motion is initiated at Creep
Speed. Used to allow the plasma torch to completely pierce the material before moving.
Creep Time
Specifies the amount of time after piercing the part that the torch travels at creep speed. Creep
speed is 25% of the programmed cut speed. After this time, the control accelerates to full cut
speed.
Arc Off Time
Specifies the amount of delay to allow prior to indicating a lost cut signal. This can be useful in
helping to minimize nuisance trips when traveling over previously cut paths in complex nested
parts.
