The cool cycles actually fire at a reduced % heat. For example,
the following schedule will have the action illustrated here:
2XWSXW&RQWURO

Note: These functions require certain outputs. Before
programming these functions, check the packet of drawings that
came with your control for I/O availability.
These functions allow the control to turn outputs on or off within
a weld schedule.

The function TURN ON WELD COMPLETE will only activate the
WELD COMPLETE output under the following conditions: There are
no active fault conditions, AND the BINARY SELECT or WELD
INITIATE inputs are still active.
Function #52 (TURN ON ISOLATION CONTACTOR) will first
check to determine if the isolation contactor is already closed, and will
pull in the isolation contactor only if it is open. This is designed to
improve the process speed, bypassing the delay provided to wait for the
isolation contactor to close.
