8. Upon completion of the “Crater Fill Delay” (maintaining the Arc Signal Relay after the weld
motion has ceased, thereby filling the weld crater) the Arc Signal Relay is de-energized and
the “Post Weld Delay” timing cycle (“P. 4”) is initiated. The cycle then proceeds to section 9.
9. Upon completion of the “Post Weld Delay” (keeping the gun/torch stationary to allow time for
any burn-back or post flow welding functions), the cycle proceeds to section 10.
10. The Cycle Control (Master) sends the “Index Command” to the Index Control (Slave).
11. The Index Control (Slave) will then drive the indexing device (motorized rack arm) at the
speed set by its speed adjustment knob, in the preset “Index Direction” (“P.I.1”). The cycle
then proceeds to section 12.
12. When the index device reaches the preprogrammed “Index Distance” value (“P.I.2”) as
counted by the engineering units, the index motion will cease and the Index Control (Slave)
will activate the “Index Complete” signal to the “Cycle Control”. The cycle then proceeds to
section 13.
13. When the Cycle Control (Master) receives the “Index Complete” signal from the Index
Control (Slave), it will reset its “Index Command” signal, which will then instruct the Index
Control (Slave) to reset its “Index Complete” signal.
a. When the Cycle Control (Master) receives the “Index Complete” signal, the cycle will
proceed to section 16, if the “Arc On/Off During Index” parameter (“P. 2”) is set to
On.
b. When the Cycle Control (Master) receives the “Index Complete” signal, the cycle will
proceed to section 14, if the “Arc On/Off During Index” parameter (“P. 2”) is set to
Off.
14. The Arc Signal Relay is re-energized (CN81 of the Cycle Control) and the “Travel Motion
Delay” timing cycle (“P. 1”) is re-initiated. The cycle then proceeds to section 15.
15. Upon completion of the “Travel Motion Delay”, the cycle then proceeds to section 16.
16. The cyclic device (“KAT”
®
) starts to travel at the speed set by its speed adjustment knob, in
the opposite direction to that of its activated limit switch. The control ignores the present
direction setting of the Forward/Neutral/Reverse switch, if any. The cycle then proceeds to
section 17.
17. The cycle continues as described between section 6 and 17 until an event described in
section 18 occurs.
18. The automatic indexing cycle continues as described until; the Run/Stop switch of the Cycle
Control (Master) is placed in the Stop position; the Forward/Neutral/Reverse switch of the
Cycle Control (Master) changes state; or the Cycle Control (Master) no longer receives the
“Ready” signal from the Index Control (Slave), at which point the cycle proceeds to section
19.
19. The cyclic device (“KAT”
®
) motion will cease immediately and the “Crater Fill Delay” timing
cycle (“P. 3”) is initiated. The cycle then proceeds to section 20.
20. Upon completion of the “Crater Fill Delay” (maintaining the Arc Signal Relay after the weld
motion has ceased, thereby filling the weld crater) the Arc Signal Relay is de-energized and
the “Post Weld Delay” timing cycle (“P. 4”) is initiated. The cycle then proceeds to section
21.
21. Upon completion of the “Post Weld Delay”, the cycle terminates, resets and displays “End”.
