Setting/selection
Pulse arc welding process (program P
END
)
The pulse arc welding process can be activated in the end program (P
END
) with the spe-
cial non-latched and special latched operating modes.
------- Function activated.
------- Function deactivated.
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

5.3.15.2 Programme limit
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).

Risk of crushing and burns!
When changing stick electrodes there is a risk of crushing and burns!
• Wear appropriate and dry protective gloves.
• Use an insulated pair of tongs to remove the used stick electrode or to move welded work-
pieces.
