Connect to mains
Plug the plug into a suitable socket.
The fuse must conform with the technical
specifications.
Start-up
Before switching on, ensure that the electrode or
electrode holder is not in contact with the welding
bench, workpiece or other electrically conductive
object so that an arc is not struck unintentionally
when switching on.
Attention !
An unintentionally drawn arc can damage the elec-
trode holder, welding bench, workpiece or device.
Operating panel, displays and func-
tions (Fig. II)
Menu / ancillary parameters button [14]
Used to call the ancillary parameters.
7-segment display [7]
Indicates the selected welding current.
If ancillary parameters are selected, the code and
the set value of the ancillary parameter are dis-
played alternately.
Fault LED [8]
Lights up if the system overheats; striking an arc is
not possible.
Once the system is switched on, the LED flashes as
a self-test.
Welding current rotary controller [10]
For stepless adjustment of the welding current.
CEL electrode LED [11]
Lights up when "CEL electrode" mode is selected.
(Electrodes with cellulose coating, suitable for verti-
cal-down welds)
Basic electrode LED [12]
Lights up when "Electrode" mode is selected.
(Electrodes with basic coating)
TIG electrode LED [13]
Lights up when "TIG electrode" mode is selected.
Electrode/TIG operating mode selector
switch [14]
The switch is used to select the operating mode "Elec-
trode" or "TIG". To select "TIG" mode, press the button.
Electrode welding method
Connect the electrode welding cable
▸
Connect the electrode welding cable to the –
ve [3] or +ve [4] socket and secure the cable by
turning clockwise.
The instructions of the electrode manufac-
turer must always be strictly observed!
Electrode welding with a positive (+)
electrode:
▸
Connect the electrode holder to the positive (+)
socket [4] of the machine and secure it by turning
the connector clockwise.
Electrode welding with a negative (–)
electrode:
▸
Connect the electrode holder to the negative (–)
socket [3] of the machine and secure it by turning
the connector clockwise.
▸
Press the lever on the handle of the electrode
holder. Clamp an electrode with the bare end in
the holder, observing the notches on the inside of
the two jaws.
Attention !
Do not connect the earthing clamp to the welding
machine or gas cylinder as otherwise the
welding current will run through the PE conductor
connections and destroy them (see Fig. III).
TIG welding method
Connect the TIG torch
▸
Connect the TIG torch to the negative socket [3]
and secure it by turning the connector clockwise.
Insert the electrode (Fig. IV)
Welding torch
▸
Grind the end of the tungsten electrode [18] so
that it forms a point
▸
Unscrew the clamping cap [19]
▸
Insert the tungsten electrode [18] through the
appropriate clamping sleeve [17]
▸
Screw on the clamping cap [19] again.
Note
Do not remove the clamping sleeve
housing [16] or gas nozzle [15].
Note the following when changing over the welding
torch to a different electrode diameter:
