Key switch
To protect against unauthorised or unintentional adjustment of the welding parameters on the machine,
the control input can be locked with the aid of a key switch.
Key position 1 =
All parameters can be set
Key position 0 =
Only the following operating elements are functional:
• “Operating mode” button
• “Welding parameter setting” rotary transducer
• “Display
switching”
button
• “TIG pulse welding”/“Select activArc” button
• “Select welding parameters” button
• “Gas test” button

Welding programs
The welding machine has 16 programs. These can be called up during the welding process.
In each selected welding task (JOB), see "Selecting the welding task" chapter, 16 programs can be set,
saved and called up. In program "0" (default setting), the welding current can be infinitely adjusted across
the entire range. In programs 1-15, 15 different welding currents (incl. operating mode and pulse function)
are defined.
Example:
Program number
Welding current
Operating mode
Pulse function
1
80 A
Non-latched
Pulses on
2
70 A
spotArc
Pulses off
The operating mode cannot be changed during the welding process. If welding is started with program 1
(non-latched operating mode), program 2 controls the setting of ignition program 1 despite the spotArc
setting and is implemented to the end of the welding process. The pulse function (pulses off, pulses on)
and the welding currents are transferred from the corresponding programs.
NOTE
Changes made to the other welding parameters during the course of the program have
the equivalent effect on all programs.
The change to the welding parameters is saved immediately in the JOB.
