Fig.4b 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
(39) (38)
The indicators shown in Fig.4b 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

(11) Welding voltage display ... for indicating the actual welding-voltage value on the
right-hand display.
Where one of the TIG-welding modes has been selected, the right-hand display
reads “0.0” before the start of welding. Where the “Rod electrode (MMA) welding”
mode has been selected, there is first a 3-second time-lag, after which the value for
the open-circuit voltage “50V” is displayed.
Important! The value of 50 V indicated where the “Rod electrode (MMA)” process
has been selected refers to the mean value of the pulsed open-circuit voltage.
(12) HOLD indicator ... every time you finish a welding operation, the actual values for
welding current and voltage are stored, and the “Hold” indicator lights up.
The “Hold” indicator refers to the last value reached by the Main current I
1
. As soon
as any other parameter is selected, the “Hold” indicator goes out. The “Hold” values
will continue to be available, however, if Parameter I
1
is selected once again.
The “Hold” indicator is cancelled whenever:
-a new welding operation is started
-the Main current I
1
is adjusted
-the operating mode is changed
-the process is changed
Important! If the main-current phase was never reached, or if a pedal remote-
control unit was being used, no “Hold” values are outputted.
(13) Set button ... is used for accessing the Set-up menu.
(14) 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.
(15) Overtemperature indicator ... lights up if the power source overheats (e.g. becau-
se the duty cycle has been exceeded). For more information on this, see the “Trou-
bleshooting” section.
