Functional characteristics
MIG/MAG welding
Item No.: 099-005073-EWM01 53
Specific latched special (n cycle)
In the n cycle program sequence, the unit starts in the 1st cycle with start program P
start
from P
1
In the second cycle, the machine switches to absolute program 2, once the start time "tstart" has elapsed.
Tapping switches to other programs (P
A1
to max. P
A9
).
Figure 5-28
The number of programs (P
An
) corresponds to the cycle number specified under N cycle.
1st cycle
• Press and hold torch trigger.
• Shielding gas is expelled (gas pre-flows).
• Wire feed motor runs at "creep speed".
• Arc ignites after the wire electrode makes contact with the workpiece, welding current is flowing (start
program P
START
from P
A1
)
2nd cycle
• Release torch trigger.
• Slope to main program P
A1
.
The slope to main program P
A1
is given at the earliest after the set time t
START
elapses and at the
latest when the torch trigger is released. Tapping (pressing briefly and releasing within 0.3 sec)
can switch to other programs. Programs P
A1
to P
A9
are possible.
3rd cycle
• Press and hold torch trigger.
• Slope to end program P
END
from P
AN
. The program can be stopped at any time by pressing the torch
trigger longer than 0.3 sec. P
END
from P
AN
is then executed.
4th cycle
• Release torch trigger.
• WF motor stops.
• Arc is extinguished after the pre-selected wire burn-back time elapses.
• Gas post-flow time elapses.
