Welding procedure selection push-button
TIG ------- TIG welding
CV -------- MIG/MAG welding with constant voltage characteristics
Default characteristics "CV constant voltage" for nearly all MIG/MAG proces-
ses
CC ------- MIG/MAG welding with constant current characteristics
Used for special wires (flux cored wires), which, according to the manufactu-
rer, are to be welded using "CC constant current"
10
Welding current polarity signal light
The signal light shows the selected polarity at the welding current socket below.
Use the welding current polarity push-button to reverse the welding current polarity of
the welding current sockets.
11
Welding procedure/MMA characteristics selection push-button
Select MMA welding procedure and electrode type
R ---------- Rutile electrode type
RB / RC - Rutile-basic/rutile-cellulose electrode type
B ---------- Basic electrode type
C ---------- Cellulose electrode type
12
Display/Power-saving mode switching push-button
AMP ----- Welding current display
VOLT ---- Welding voltage display
kW ------- Welding performance display (both signal lights are illuminated)
STBY ---- Press for 2 s to put machine into power-saving mode. To reactivate, activate
one of the operating elements.
13
Welding data display (3-digit)
Displays the welding parameters and the corresponding values
> see 4.2.1 chapter
4.2.1 Welding data display
All relevant welding parameters with their values are shown depending on the welding procedure selected
and the associated functions. Machine parameters and error codes are shown as well in a unique man-
ner. The meaning of the parameters and values shown is explained in the relevant chapter for the func-
tion.
Next to the display is the Display/Power-saving mode switching push-button. Each time the push-button is
pressed the display switches between the desired parameters.
Depending on the process, the parameters are shown as nominal values (before welding), actual values
(during welding) or hold values (after welding):
MMA welding, TIG welding and MIG/MAG welding with constant current (CC):
