5.18 Protecting welding parameters from unauthorised access
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” button
• “Select welding parameters” button
• “Gas test” button
5.19 Welding
programs
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.
The welding machine has 16 programs, which you can change during welding.
In each selected welding task (JOB), - See 5.13.3 Welding task selection 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
80A
Non-latched
Pulses
on
2 70A
Latched
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 latched
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.
