One of the LEDs

A
, or

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
means of a high voltage/frequency device.
TIG
LED
B
:
PULSE TIG welding, started by means of a
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
starting (striking).
LED
AU
:
PULSE TIG welding with contact starting
(striking). The operating logic is the same as
described for LED
B
.
Program key AR.

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
