Arc Shutdown Time

Arc shutdown time is the length of time that the Pinnacle supply interrupts power flow
in response to an arc. Selecting a target type of "metal" or "non-metal" will pre-select
arc shutdown times for you. However, if you want a custom arc shutdown time, select
one based on system conditions. To extinguish an arc properly, the power supply must
interrupt power until the output (arc) current decays to a value near 0. The decay of
output current largely depends on system cable inductance and the impedance of the
arc. If you select an arc shutdown time that is shorter than the actual decay time of the
arc current, then the Pinnacle automatically extends its arc control circuitry. You can
set a custom arc shutdown time through the ARC menu on the Pinnacle Active
Remote Panel or through AE Bus/PROFIBUS Command 8 (see Chapter 4).
