1. The automatic cycle is initiated by placing the Forward/Neutral/Reverse switch in either the
Forward or Reverse position and the Run/Stop switch in the Run position. The cycle then
proceeds to section 2.
2. The Arc Signal Relay(s) (GK-191-P-071) is energized and the Travel Motion Delay is
initiated. The cycle then proceeds to section 3.
3. Upon completion of the Travel Motion Delay, the “MAGNETIC MOGGY” carriage starts to
travel in the direction set by the Forward/Neutral/Reverse switch, at the speed set by the
potentiometer.
a. If the “MAGNETIC MOGGY” is a GM-03-350 the cycle then proceeds to section 9.
b. If the “MAGNETIC MOGGY” is a GM-03-300 and the Stitch Weld Parameter (P.4) is
set to OFF, the cycle then proceeds to section 9.
c. If the “MAGNETIC MOGGY” is a GM-03-300 and there is a numeric value entered in
the Stitch Weld Parameter (P.4), the cycle then proceeds to section 4.
4. When the carriage has travelled the distance equal to that set in the Stitch Weld Parameter
(P.4), the weld travel will cease and the Crater Fill Delay timing cycle will initiate. The cycle
will then proceed as per section 5.
5. Upon completion of the Crater Fill Delay (maintaining the Arc Signal 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 is initiated. The cycle then proceeds to section 6.
6. Upon completion of the Post Weld Delay (keeping the carriage stationary to allow time for
any burn-back or post flow welding functions), the “MAGNETIC MOGGY” carriage travels at
full speed in the same direction, until the carriage has travelled the distance equal to that set
in the No- Weld Spacing parameter (P.5), at which point the travel ceases immediately. A
set timing delay of 0.7 seconds elapses, allowing the carriage to come to a complete stop,
before the cycle continues to section 7.
7. The Arc Signal Relay is re-energized and the Travel Motion Delay is initiated. The cycle then
proceeds to section 8.
8. Upon completion of the Travel Motion Delay, the “MAGNETIC MOGGY” carriage starts to
travel in the direction set by the Forward/Neutral/Reverse at the speed set by the
potentiometer. The cycle continues as described between section 4 and 8 until an event
described in section 9 occurs.
9. 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 limit switch is activated, then the travel
motion will cease, and;
a. If the Arc Signal was not energized, the cycle is now completed and “End” is displayed.
b. If the Arc Signal was energized, the Crater Fill Delay will commence. Upon completion of the
Crater Fill Delay, the Arc Signal will de-energize and the cycle is now completed and “End” is
displayed.
