Setting/selection
Correct wire burn-back (setting range 0
–499)
If too high a value is set, a large ball will form at the tip of the wire electrode (bad re-
ignition) or the wire electrode sticks to the contact tip. If too low a value is set, the wire
electrode sticks to the weld pool.
• Increase value > increase wire burn-back
• Decrease value > decrease wire burn-back
Setting JOB-dependent program limit/n-cycle
The JOB-dependent program limit allows you to limit the number of programs that can be
selected in the selected JOB to (2...9). This option can be set individually per JOB. In
addition, a legacy option to set a "global program limit" is also available. To set this
option use special parameter P4. This setting is then applied to all JOBs for which no
JOB-dependent program limit has been set (see the special parameters description).
You can also use the "Special latched (n-cycle)" operating mode if special parameter 8 is
set to 2. In this case (JOB-dependent program switching activated, special parameter
8 = 2, special latched) you can switch to the next program by tapping the torch trigger in
the main program (see the special parameters description).

JOB-dependent program limit for max. selectable programs.
For machine versions with pulsed arc welding procedures only.
Change welding process (process switching)
With this function activated the welding process switches from standard arc welding to
pulse arc welding. Switching is effected by either tapping the torch trigger (special
latched) or by activating the superPuls function (switch between program P
A
and P
B
).
on
Function activated.
off
Function deactivated.
Pulse arc welding process (program P
START
)
The pulse arc welding process can be activated in the start program (P
START
) with the
special non-latched and special latched operating modes.
on
Function activated.
off
Function deactivated.
Pulse arc welding process (program P
END
)
The pulse arc welding process can be activated in the end program (P
END
) with the
special non-latched and special latched operating modes.
on
Function activated.
off
Function deactivated.
For machine versions with pulsed arc welding procedures only.
Ignition type (MIG/MAG)
Application: Low-spatter ignition, e.g. for aluminium and chrome/nickel materials.
0 =
Traditional arc ignition
1 =
Arc ignition with wire return for push/pull applications
2 =
Arc ignition with wire return for non-push/pull applications
