Process key AT.
One of the LEDs AX, AV, or AW lights when
selected.
LED AX
LED AV
Mode key AS.
One of the LEDs D, C, E, B, A, or AU lights when
selected:
LED D "HOT START"
MMA welding active.
This LED lights to indicate that the display U displays the
time, expressed in seconds, during which the welding
machine delivers an overcurrent to improve electrode
starting. It may be adjusted using the knob Y.
LED C "Arc-Force"
MMA DC welding active.
This is a percentage of the welding current. The display U
displays its value, and the knob Y adjusts it. This over-
current essentially aids in the transfer of drops of molten
metal.
LED E:
CONTINUOUS TIG welding, started by
TIG
means of a high voltage/frequency device.

LED B:
PULSE TIG welding, started by means of a
TIG
high voltage/frequency device.
The pulse frequency is adjustable from 0.16 to 500Hz
(LED AE); the peak current and the base current may be
activated via the LEDs AG and AD, respectively, and are
adjustable using the knob Y.
From a pulse frequency of 0.16 to 1.1Hz, the display O
alternately shows the peak (main) current and the base
current. The LEDs AD and AD light alternately; above 1.1
Hz the display O shows the average of the two currents.
LED A:
CONTINUOUS TIG welding with contact
TIG
starting (striking).
LED AU:
PULSE TIG welding with contact starting
TIG
(striking). The operating logic is the same as
described for LED B.
Program key AR.
One of the LEDs G, F, W, X, Z, or AA lights when
selected.
LED G:
Spot-welding (Manual).
After selecting the welding current (LED AG) and the spot
welding time (LED AE) using the selector switch AP, set
the values using the knob Y.
This welding mode is only used if continuous welding is
selected and high-frequency start is used (LED E lit). The
operator presses the torch trigger, the arc lights and shuts
