Machine setting for welding without inert gas
If you use flux-cored wire with integrated inert gas,
there is no need to supply external inert gas.
• First connect the polarity changeover (11) with the
negative pole (10). Lock the connector by turning it
clockwise.
Connect the hose assembly (27) to the connector
(8) and fix it by tightening the nut at the connection
point.
• Then connect the earth clamp (32) with the corre-
sponding positive terminal (9) and turn the terminal
clockwise to fix it.
• Insert the flux-cored wire as described under "As-
sembly of the welding wire reel".
Device setting for welding with rod electrodes
1 Select the MMA welding function on the selection
button (22).
2 Connect the earth cable (32) to the positive termi-
nal (9) marked and lock the connector by turning
it clockwise.
3 Next, connect the welding cable to the negative
terminal (10) marked and lock the connector by
turning it clockwise. NOTE! The polarity of the
wires may vary! All information regarding polari-
sation should be available on the packaging of the
electrodes supplied by the manufacturer!
4 Now the mains cable can be connected and the
power supply activated. After connecting the earth
cable to the welding machine, work can begin.
MMA welding
• Prepare the device as described previously under
"Device setting for welding with rod electrodes".
• Put on suitable protective clothing in accordance
with the specifications and prepare your workplace.
• Connect the earth clamp (32) to the workpiece.
• Clamp the electrode in the electrode holder (31).
• Switch the device on by setting the ON/OFF switch
(2) to the "I" ("ON") position.
• Select "MMA" mode by pressing the selection but-
ton (22) until the indicator light next to "MMA" (20)
lights up.
• Adjust the welding current with the welding current
adjustment potentiometer (4) to suit the electrode
used.
• Hold the protective welding mask in front of the face
and start welding.
• To complete the working process, set the ON/OFF
switch (2) to the "O" ("OFF") position.

m Attention!: The earth clamp (32) must not be
brought into direct contact with either the electrode
holder (31) or the electrode.
m Attention!: Do not dab the electrode on the work-
piece. It could be damaged and the ignition of the arc
could be made difficult. Once the arc has ignited, try
to maintain a distance from the workpiece that corre-
sponds to the electrode diameter used. The distance
should remain as constant as possible while you are
welding. The electrode inclination in the working direc-
tion should be 20–30 degrees.
m Attention!: Always used tongs to remove used elec-
trodes or move hot workpieces. Note that the electrode
holder must always be placed on an insulating base
after welding.
The slag should only be removed from the seam once it
has cooled. To continue a weld on an interrupted seam:
• First remove the slag at the connection point.
• The electric arc is struck in the weld groove, guided
to the connection point, properly melted there and
then continued along.
m Attention!: The welding work generates heat.
Therefore, the welder must be left idle for at least half
an hour after use. Alternatively, let the device cool
down for one hour. The device must not be packed and
stored until its temperature has normalised.
m Attention!: A voltage that is 10% lower than the rat-
ed input voltage of the welding machine can lead to the
following consequences:
• The current of the unit decreases.
• The arc breaks off or becomes unstable.
m Attention!:
• The arc radiation can cause eye inflammation and
skin burns.
• Spray and molten slag can cause eye injuries and
burns.
• Assemble the welding shield as described under
"Assembling the welding mask ".
