The control LED’s
The following control LED’s give an overview of the important status conditions of
the machine:
Whether conventional or high frequency pulsing this LED will
illuminate to indicate that pulsing is activated. (See chapter 3.3.2.
und 3.3.4.)
There is open circuit voltage on the torch or the electrode holder.
In the case that this LED flashes on and off then an internal fault
condition has been recognised. This can be reset by power off and
then on again. If fault cannot be cleared then please contact Rehm
customer service (RKS).
Temperature control. This (yellow) LED will illuminate if the
maximum allowable temperature of the machine has been exceeded.
As long as this LED is illuminated then the power module is disabled,
therefore there is no output from the power source possible. In the
TIG welding mode when this fault condition occurs the post flow gas
time will still elapse. Once the machine cools down again the LED
will extinguish and the welding operation can continue as before. If
this Led starts to flash off and on, and the digital display shows and
„Err“ then an internal fault has been recognised. This can be reset
by power off and then on again. If fault cannot be cleared then
please contact Rehm customer service (RKS).
3.3.20 The Digital display
The digital display enables the selection of the parameters and their values to be
displayed. The display is a three-digit display. Its large display area with self-
illuminating digits enables the display to be easily read, even from a distance and
also in poorly lit conditions. As the display is control via the processor it always
show the values and status in real time. This means for example that when a
progra
mme is to be stored the point beside the letter “S” can also be displayed to
indicate that the programme is already number selected is already occupied.
3.3.21 The Turn and Set knob
The settings are all done via a single control knob, this can be turned to select or
alter the parameter and then pressed to confirm the setting. Using the
combination of LED’s and the 3
-digit digital display the setting can always be
accurately set and reproduced using the same principle. This turn and set knob is
positioned centrally on the operating panel and is suitable for both right handed
and left handed personnel, as it can easily be operated with the thumb. The form
of the knob enables both simple and precise setting of the parameters and
functions. It is fully integrated within the housing of the Tiger and is therefore
protected by mechanical damage. Even if it is knocked from above the electrical
components within the housing remain undamaged. The turn and set knob is a
combined encoder and switch. As such it does not have an end stop therefore it
cannot be damage by truing it past the end point.
3.4 Anti-Stick Function
If there is a permanent short circuit between the electrode and the workpiece
during welding, the Anti-Stick Function is automatically activated after approx.
1.3s. This function automatically limits the welding current to approx. 35 A. This
