MMA welding
Make sure that the main switch
5
is set to position “O” (“OFF”) or that
the power plug
3
is not plugged
into the socket.
Connect the electrode holder
34
and
the earth terminal
4
to the welding
device, as shown in Fig. AC). Also
refer to the information from the
electrode manufacturer.
Put on appropriate protective cloth-
ing in accordance with the specifica-
tions and prepare your workspace.
Connect the earth terminal
4
to the
workpiece.
Clamp the electrode into the elec-
trode holder
34
.
Switch the device on by setting the
main switch to the
5
“I” (“ON”)
position.
Select “MMA” mode by pressing the
selector switch for welding mode
35
,
until the small indicator lamp next to
MMA lights up.
Adjust the welding current using the
rotary switch for welding current
adjustment
6
depending on the
electrode you are using.
Note:
Guideline values for the welding
current to be used, depending on the
electrode diameter can be taken from
the following table.
Ø Electrode
Welding current
1.6 mm
40–55 A
2.0 mm
55–65 A
2.5 mm
65–80 A
3.2 mm
80–120 A
Note:
By pressing the voltage reducer
selector key
37
you can activate the
voltage reducer function (VRD). The LED
next to “A/VRD” lights up. By doing this
the output voltage is reduced and the
safety for the user during breaks from
welding will be increased.
Attention:
Do not bring the earth
terminal
4
and the electrode holder
34
/
electrodes into direct contact with one
another.
Attention:
When welding with rod
electrodes, the electrodeholder
34
and
the ground terminal
4
must be con-
nected in accordance with the informa-
tion from the electrode manufacturer.
Hold the welding mask
22
in front of
your face and start the welding
procedure.
To stop the procedure, set the main
switch ON/OFF
5
to “O” (“OFF”)
position.
Attention:
When the thermal sensor
is triggered, “O.H.” will be shown on
the digital display. In this case, it will
not be possible to continue welding.
The device will remain in operation so
that the fan can cool the device. As
soon as the device is ready for opera-
tion again, the “O.H.” display will
disappear. The welding function can
now be used again.
