5. TRAVEL START DELAY - Rotation of the arc should not occur in most cases, until full
penetration of the weld has been achieved. When the arc is established the TRAVEL
START DELAY time will begin to count. When this programmable period of time is
complete the weld head will start to rotate the arc.
6. WIRE FEED START DELAY - Feeding of the Wire should not occur, in most cases,
until travel has started. When the arc is established the WIRE FEED START DELAY
time will begin to count. When this time is complete the wire will be able to feed if the
Wire Mode is set to ON.
7. AVC START DELAY - The AVC should not be turned on until the current is near full
value and the puddle has stabilized. When the arc is struck the AVC START DELAY
time will begin to count. When this time is complete the AVC will be able to operate.
8. OSCILLATOR UPSLOPE - The Torch Oscillator Upslope is linked to the current
Upslope time. During the Current Upslope time the Oscillator Amplitude (movement)
will start at 0 amplitude and slowly increase to the full program value of OSC Amplitude
by the end of current Upslope.
9. OSCILLATOR DWELL and EXCURSION TIMERS - The Oscillator movement is based
on time. The Level 1 Dwell and Excursion Timers start counting at the beginning of
Event #3 (if OSC MODE is set to ON).
4. EVENT 4: FULL LEVEL FUNCTIONS - Sometime after the arc is established, depending on
the weld schedule, the current UPSLOPE, OSC UPSLOPE and all START DELAYS (Travel,
Wire, AVC) will be completed and all of the following functions will be in effect:
1. LEVEL 1 TIME - Will be counting towards 0. During its count all of the below functions
will be occurring:
2. LEVEL 1 PULSE MODE - The PULSE MODE can be set in each LEVEL to work
several different ways:
ON = In the ON mode system will pulse between PRIMARY and BACKGROUND
function values using the PULSE TIMERS for timing control.
OFF = In the OFF mode all system functions will be in PRIMARY only. No
BACKGROUND functions will be done.
SYNC = In the SYNC Mode the system will pulse between PRIMARY and
BACKGROUND function values using the Oscillator Dwell and Excursion Timers for
pulse control.
3. LEVEL 1 PRIMARY PULSE TIME - If the LEVEL 1 PULSE MODE is ON this function
will now be timing the Primary pulses (see Event 3).
4. LEVEL 1 BACKGROUND PULSE TIME - If the LEVEL 1 PULSE MODE is ON this
function will now be timing the Background pulses.
5. LEVEL 1 PRIMARY AMPS - After UPSLOPE the system will be regulating this
programmed value of current each time the system goes to Primary Pulse either using
the Level 1 Primary Pulse Time or the Level 1 Osc Dwell Time if the Level 1 Pulse
Mode is in SYNC.
6. LEVEL 1 BACKGROUND AMPS - If the LEVEL 1 PULSE MODE was programmed to
ON or SYNC, the system will be regulate the Level 1 Background current value after
each Level 1 Primary pulse.
7. LEVEL 1 TRAVEL MODE - After the TRAVEL START DELAY time is complete the
Travel will function in one of these programmable modes.
