No. Function
(11) Welding current indicator
for indicating the welding current for the welding parameters
- Starting current I
S
- Welding current I
1
- Final current I
E
Before welding commences, the left-hand digital display shows the set
value. For I
S
and I
E
, the right-hand digital display also shows the re-
spective percentage of the welding current I
1
.
After welding begins, the welding parameter I
1
is automatically selec-
ted. The left-hand digital display shows the actual welding current
value.
In the welding parameters overview (9), LEDs for the various paramet-
ers (I
S
, I
1
, etc.) light up to show the relevant position in the welding pro-
cess.
(12) Left parameter selection button
for selecting welding parameters within the welding parameters over-
view (9)
When a welding parameter is selected, the LED on the relevant para-
meter symbol lights up.
(13) HF (high frequency) ignition indicator
lights up when the HFt setup parameter has been set to an interval for
the high frequency pulses
(14) Overtemperature indicator
lights up if the power source overheats (e.g. because the duty cycle has
been exceeded). See the "Troubleshooting" section for more informa-
tion.
(15) Keylock switch (option for TT 2500 / 3000 / 4000 / 5000)
When the key is in the horizontal position, all parameters and functions
are disabled with the exception of the currently selected parameter or
function.
