command is released to the “KAT”
®
carriage, the carriage release icon on the
lower right corner of the LCD screen will appear as follows:
The Program push button changes the control state from running (operational) mode
to programming mode, and back to running mode. While-ever the control is in
programming mode, the program icon on the lower right corner of the LCD screen
will appear as follows:
AUTOMATIC CYCLE OPERATION
To perform an automatic welding cycle:
1. Place the Oscillator control Manual/Hold/Auto switch in the Hold position.
2. Place the “KAT”
®
carriage control Run/Stop switch in the Run position.
3. Set the “KAT”
®
carriage travel speed by placing the “KAT”
®
carriage control
Forward/Neutral/Reverse switch in the Neutral position then rotate the Speed Adjustment
knob until the desired speed is displayed.
4. Place the “KAT”
®
carriage control Forward/Neutral/Reverse switch to the desired weld travel
direction.
5. Using the devices on the Oscillator control, set the desired oscillation width, oscillation
speed and dwells.
6. When the Oscillator control Manual/Hold/Auto switch is placed in the Auto position, the
programmable audible warning buzzer duration elapses while the optional buzzer is
energized (if the optional buzzer is not installed this timing cycle is usually programmed off).
Then the oscillation motion will commence and the arc activation signal will be energized (if
the Arc Enable/Disable switch is in the Enable position). Following the Travel Motion Delay,
the Hold (stop) signal to the “KAT”
®
carriage control is released and the carriage starts its
weld travel.
7. When the Oscillator control Manual/Hold/Auto switch is placed in the Hold position, the Hold
(stop) signal to the “KAT”
®
carriage control is energized again, stopping the “KAT”
®
carriage
travel, and the Oscillator Head motion is stopped. After a programmable Crater Fill Delay
the arc activation signal is de-energized and the automatic cycle is completed.
The following are some notes on the operation of the control.
1. When the oscillation is to start, the Oscillator control will always assume that the oscillator
head/slide is resting at the “Oscillation Rest Location” (4 th Field of the Features & Setup
screen, described later in this manual) and will travel in the appropriate direction
accordingly. I.e. if the “Oscillation Rest Location” field is set to C, the oscillator will start its
oscillation cycle by moving in the relevant direction toward the B (center) location by a
distance of half the width value (W).
