Designation
Overtemperature indicator
lights up if the power source overheats (e.g. because the duty cycle has been ex-
ceeded). See the "Troubleshooting" section for more information.
Special indicators
Pulse indicator
lights up when the F-P setup parameter has been set to a pulse frequen-
cy
Spot welding indicator
lights up when the SPt setup parameter has been set to a spot welding
time
Tacking indicator
lights up when the tAC setup parameter has been set to a period of time
Electrode overload indicator
lights up if the tungsten electrode is overloaded.
See section on TIG welding under "Welding" for more information on the
electrode overload indicator.
HF (high-frequency) ignition indicator
lights up when the HFt setup parameter has been set to an interval for
the high-frequency pulses
Left digital display
HOLD indicator
at the end of each welding operation, the actual values for the 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
as any other welding parameter is selected, the Hold indicator goes out. The Hold
values will, however, continue to be available if welding parameter I1 is selected
again.
The Hold indicator is cleared when:
-
a new welding operation is started
-
the welding current I
-
the mode is changed
-
the process is changed
IMPORTANT! Hold values are not output if:
-
the main current phase was never reached,
or
-
a pedal remote control was used
Right digital display
Welding voltage indicator
lights up when parameter I
The actual welding voltage value is shown on the right digital display during weld-
ing.
Before welding, the following appears on the right digital display:
-
0.0 if a TIG welding mode is selected
-
~ 93 V if a MMA welding mode is selected (after a delay of 3 seconds; the
average value for the pulsed open-circuit voltage is ~ 93 V)
