SECTION IV - SYSTEM FUNCTIONS
4.3 WELD SEQUENCE
4. EVENT 4: FULL LEVEL FUNCTIONS -
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.
OFF
= Will prevent rotation from occurring.
CONT
= Runs the travel at the PRIMARY-RPM speed only,
regardless of PULSE MODE.
STEP = Will pulse the travel between the PRIMARY-RPM and
BACKGROUND-RPM speed. If the TRAVEL MODE is in
STEP but the PULSE MODE is in OFF then only PRIMARY will
occur (without pulsing there are no background functions).
8. LEVEL 1 PRIMARY-RPM - After the Travel Start Delay time is
complete the travel function will begin. If the Level 1 Travel Mode is
programmed to CONT the travel will be rotating the arc at the Primary-
RPM rate continuously regardless of any pulsing. If the Travel Mode is
STEP it will rotate the arc at the Primary-RPM speed each time the
system goes to PRIMARY.
9. LEVEL 1 BACKGROUND RPM - If the LEVEL 1 PULSE MODE is in
ON or SYNC and the TRAVEL MODE is in STEP the system will
rotate the arc at the BACKGROUND-RPM each time the system goes to
a BACKGROUND pulse.
NOTE
Travel direction is programmable CLOCKWISE or COUNTER-
CLOCKWISE. After the Travel Start Delay the Head will rotate in the
programmed direction. The direction is not programmable by LEVELS.
