Gas-test button
... for setting the required gas-flow rate on the pressure regulator.
After you press this button, gas will flow out for 30 s. Press the button again to stop
the gas test-flow before the 30 seconds are up.

Overtemperature indicator
... lights up if the power source overheats (e.g.
because the duty cycle has been exceeded). For more information on this, see the
“Troubleshooting” section.
Fig.3b Additional indicators
(38) Pulsing is activated ... Set-up parameter “F-P” has been set to a certain pulsing
frequency
(39) Spot welding is activated ... Set-up parameter “SPt” has been set to a certain spot-
welding time
(40) Tacking is activated ... Set-up parameter “tAC” has been set to a certain duration
(41) “Electrode overload“ indicator ... lights up when the cap at the tip of the tungsten
electrode is overloaded. This means that there is a risk of an excessively large cap
being formed.
Causes:
-
The tungsten electrode does not have a large enough diameter
-
Main current I
1
has been set to too high a value
-
“Balance” has been set too far towards “+”
Remedies:
- Use a tungsten electrode with a bigger diameter
- Reduce the main current and/or set “Balance” further towards “-”
Important!
The “Electrode overload“ indicator (41) is fine-tuned to work with the
following tungsten electrodes:
-
TIG-AC welding: Pure tungsten electrodes
-
TIG-DC welding: Ceriated electrodes
For all other electrodes, the “Electrode overload” indicator (41) must be taken as a
guideline only
(42) “Keylock activated” indicator ... lights up when the keylock is activated, as
described in the section headed “Special functions”
(43) Cold-wire feeder is connected ... This indicator lights up when a cold-wire feeder is
connected
(44) HF (high-frequency) ignition is activated ... Set-up parameter “HFt” has been set to
a certain interval for the high-frequency impulses
The indicators shown in Fig.3b glow for as
long as the respective functions remain
activated. The following description will
give you an overview of these functions.
In some cases, they will be described in
even greater detail in the in-depth
sections dealing with the function or
parameter in question, to be found in:
-
The set-up menu: Level 1
-
The set-up menu: Level 2
