Forward/Neutral/Reverse direction switch is placed in the Neutral position; or the
relevant optional travel limit switch is activated, at which point the travel will
immediately stop and the cycle is then completed and “End” is displayed.
b. If the switch is set to the same direction as the Weld Direction parameter, or if the
Weld Direction parameter is set to both Forward & Reverse, then the cycle proceeds
to section 4.
4. The optional Arc Signal Relay (GK-191-P-071) is energized and the Travel Motion Delay is
initiated. The cycle then proceeds to section 5.
5. Upon completion of the Travel Motion Delay, the Kat carriage starts to travel in the direction
set by the Forward/Neutral/Reverse switch (detected and recorded at the onset of the
cycle), at the speed set by the potentiometer. The cycle then proceeds to section 6.
6. When the Run/Stop switch is placed in the Stop position, or the Forward/Neutral/Reverse
switch is placed in the Neutral position, or if the relevant forward or reverse optional limit
switch is activated, then the travel motion will cease, and the Crater Fill Delay will
commence. The cycle then proceeds to section 7.
7. Upon completion of the Crater Fill Delay (maintaining the Arc Signal after the weld motion
has ceased, thereby filling the weld crater), The optional Arc Signal Relay is de-energized.
The cycle then proceeds to section 8.
8. If the cycle was stopped via:
a. The Run/Stop switch or the Forward/Neutral/Reverse switch, the cycle is now
completed and “End” is displayed.
b. If the cycle was stopped via the relevant forward or reverse optional limit switch and
either the Automatic Return To Home parameter is set to Off; or the Weld Direction
parameter is set to both Forward & Reverse, the cycle is now completed and “End” is
displayed.
c. If the cycle was stopped via the relevant forward or reverse optional limit switch and
the Automatic Return To Home parameter is set to On (and the Weld Direction
parameter is not set to both Forward & Reverse), and the opposite limit switch to the
Weld Direction is detected and not activated, then the Post Weld Delay timing cycle
is initiated and the cycle proceeds as per section 9.
9. Upon completion of the Post Weld Delay (keeping the carriage stationary to allow time for
any burn-back or post flow welding functions), the cycle will continue as per section 10.
10. The carriage will travel in the opposite direction to that of the Weld Direction parameter, at
full speed, until the activation of the home limit switch (the optional limit switch in the
opposite direction to that of the Weld Direction parameter). The cycle then proceeds to
section 11.
11. Upon the activation of the home limit switch the carriage return travel will immediately stop
and the cycle is then completed and “End” is displayed.
