3.0 OPERATION
3.1 OPERATIONAL SEQUENCES
The following operational sequence is the control operational sequence.
• To operate the control , place the ATC-3 Control power switch to the "ON" position.
The NET, +5VDC and +36 VDC LED’s will illuminate. The ATC-3 Operator Pendant
will display the Software Version banner until power up sequence is complete. When
the power up sequence is complete, the Pendant Display will display “INITIALIZE”.
•
To initialize the ATC-3 , turn the "MODE" switch to the "MAN" position. The Torch
carriage will move to the upper slide limit switch (toward the slide Motor) and stop.
Turn the “MODE” switch to the “OFF” position.
This operation must be performed
every time the ATC-3 is powered on .
If a Torch Weld Position is saved in the Operator Pendant, the slide will move the
torch to the saved position after the Home Routine is completed.
• To manually move the Torch Slide use the "JOG" switch. Holding the "JOG" switch
in the " UP " direction will move Torch Slide in the up direction. Holding the "JOG"
switch in the "
DOWN
" position will move the torch slide in the down direction. The
"JOG" switch is disabled when the "TRACKING" Switch is on or the “REMOTE
TRACKING INPUT” is active and the "Welding ARC IS ACTIVE".
To save the current touch position as the Start Weld Position rotate the MODE Switch
to the MAN position.
•
To Perform a Touch Retract use the PROGRAM / ALTER / SELECT switch then
turn the Touch Retract Feature ON then enter a retract distance in the “RETRACT=”.
Use the JOG switch to move the Torch the desired Start Touch Retract position then
save the position as the Start Weld Position.
To start the Touch Retract function rotate the MODE switch to the TRACKING
position. The Slide will move to the Start Weld Position, stop, and then run the search
routine until the part is found, stop and then retract.
If the part is not located within 0.5 inch from the start search position the ATC-3 will
generate a
“TC ERROR - NO TOUCH “
fault.
• When the MODE Switch is set to Tracking and the Weld ARC is active the operator
can use the JOG switch to change the Torch Height Tracking Reference to change
the Tracking ARC Length. The JOG switch will increment or decrement the tracking
reference 1 value for each time it is toggled from OFF to ON.
• When the MODE switch is set to OFF(not Tracking) while the Weld ARC is Active the
operator can use the Jog UP/DOWN switch to manipulate the torch position while
welding. When using this operation mode adjust the Jog Speed to provide operator
with the best movement control.
