5.4.15.3 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).

Welding torch connection
TIG welding torches to be connected to a Euro torch connector are available in two versions:
• TIG combi welding torches are connected to the Euro torch connector of the wire feeder and to
the (-) welding current plug of the power source.
• TIG welding torches of the EZA version are connected to the Euro torch connector of the wire
feeder only. To do so, the welding current lead of the intermediate hose package must be
connected to the (-) welding current connection at the rear of the unit!
