SECTION IV - SYSTEM FUNCTIONS
4.3 WELD SEQUENCE
4. EVENT 4: FULL LEVEL FUNCTIONS -
4. LEVEL 1 BACKGROUND PULSE TIME - If the LEVEL 1 PULSE
MODE is ON this function will operate (see Event 3).
5. LEVEL 1 PRIMARY AMPS - After UPSLOPE the system will be
regulating this programmed value of current.
6. LEVEL 1 BACKGROUND AMPS - If the LEVEL PULSE MODE was
programmed to ON, the system will be pulsing between the PRIMARY
VALUE and the BACKGROUND VALUE.
7. LEVEL 1 TRAVEL MODE - After the TRAVEL START DELAY time
is complete the travel function will be allowed to operate in 1 of 3
programmable modes.
OFF = Will prevent rotation from occurring.
CONTINUOUS = 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 them only PRIMARY will
occur (without pulsing there are no background
functions).
8. LEVEL 1 PRIMARY-RPMS - After the TRAVEL START DELAY
time is complete the travel function will begin. If the LEVEL 1
TRAVEL MODE is programmed to the CONTINUOUS mode the travel
will be rotating the arc at the PRIMARY-RPM rate. If the mode is in
STEP it will rotate the arc at the PRIMARY-RPM speed each time the
LEVEL 1 PRIMARY PULSE TIME occurs.
9. LEVEL 1 BACKGROUND-RPM - If the LEVEL 1 PULSE MODE is
ON and the TRAVEL MODE is in STEP the system will rotate the arc
at the BACKGROUND-RPM each time the LEVEL 1 BACKGROUND
PULSE TIME occurs.
