Setting the welding current (absolute/percentage)

The parameters that can be set in the machine control function sequence are dependent on the welding
task selected. This means that if no pulse variant was selected, for example, no pulse parameters will be
available to set in the function sequence.
The welding current for the ignition, secondary, end and hot start current can be set as a percentage of
the main current I

Lock function

The lock function protects against accidental changes to the machine settings. All operating elements are
deactivated when the function is activated and the signal light of the lock function is on. Press and hold
(> 2 s) the push-button
32
Setting/selection
Fast take-over of control voltage (automation)
------- Function enabled
------- Function disabled (ex works)
Welding procedure DC+ (TIG)
Protection against an accidental selection of polarity DC+ and the associated destruction
of the tungsten electrode (factory setting).
------- Polarity switching to DC+ is possible.
------- Polarity switching is disabled (factory setting).
Gas monitoring
Depending on where the gas sensor is situated, the use of a pilot static tube and the
welding process monitoring phase.
------- Function disabled (ex works).
------- Monitoring during the welding process. Gas sensor between gas valve and
welding torch (with pilot static tube).
------- Monitoring prior to the welding process. Gas sensor between gas valve and
welding torch (without pilot static tube).
------- Permanent monitoring Gas sensor between gas cylinder and gas valve (with
pilot static tube).
Arc detection for welding helmets (TIG)
Modulated waviness for better arc detection
------- Function disabled
------- Medium intensity
------- High intensity
or as an absolute value.
