2.9.3.3 Strike Current
This is the current value at which the arc will strike and initiate an arc.
Valid values are from 5.0 to 25.0 amps.
2.9.3.4 Tacks
Number
This value determines how many tacks are required around the
circumference of the item to be welded. Multiple tacks will occur at
opposing points with the last tack opposite Home or the programmed
Start Position. Valid values are from 0 to 8 tacks.
Time
This value defines the duration of each tack. Valid values are from 0.5
to 5.0 seconds. If no tacks are requested the tack time will not be
available.
Current
This value defines the heat intensity of the tack. Valid values are from
1.0 amp to the maximum amp value in the procedure. If no tacks are
requested the tack current will not be available.
2.9.3.5 Start Position
This value defines the position, in degrees clockwise (normal forward
rotating direction of the rotor) from the Home position, that the procedure
will start welding. This assumes the weldhead is held in the vertical
position with the rotor opening at the top and the tungsten at about the
three o’clock position.
If the welding is to start at Home, the Start Position value should be
zero. If the welding is to start at the bottom of the weldhead, a value
of ninety should be entered.
When Start Position is enabled, the ACL program requests an additional
parameter as the [1 Weld with Procedure ———] option is selected from
the MAIN MENU. This additional parameter, “Weldhead Angle”, is the
degree angle of the weldhead from the vertical.
When the procedure is started, following the Pre-Purge, the rotor will
move to the specified Start Position plus the added Weldhead Angle
value. When used with the tacking feature, the final tack will occur
opposite the Start Position, the added Weldhead Angle simply adjusts
for the orientation of the weldhead position
This feature is available with, and only if the Start Position option has
been enabled at the Procedure Options screen.
2.9.3.6 Post-Purge Time
This is the amount of time that the purge gas will flow once the welding
arc has extinguished, regardless if the procedure has fully completed or
whether the operator has prematurely halted the procedure by pressing
[STOP]. Valid values are from 0.02 to 300.00 seconds.
2.10 Procedure Up-Slope Information Screen
This section of the program is used to set values for Level 1 of the procedure.
Level 1 of each procedure is considered the Up Slope Level; in this Level
current and rotor speed will initiate and start the welding arc, commence
rotation of the rotor and take the procedure to its programmed welding
parameters.
When the cursor box is at the Level Number the parameters for that Level
will show underneath. Changing Levels can be done in several ways: enter
the number of the Level to be viewed then press [ENTER], or press [PAGE
DOWN] to scroll to the next Level or [PAGE UP] to scroll to the previous
Level.
