Before Commissioning; Start Up - Scheppach WSE5000-Multi Bedienungsanleitung

• As soon as the wire projects ca. 5 cm from the front,
release the burner button again. Then switch the
machine off again and pull out the mains plug!
• Now, screw the contact tip (l) on again and ensure
that the contact tip matches with the diameter of the
welding wire used.
• Finally, re-attach the burner nozzle (m).

Before commissioning

Selection button for welding process (22)
Use the welding process selection button to select the
welding process you want to use.
Selection button for welding wire diameter (26)
Use the welding wire diameter selection button to se-
lect the wire you are using.
Potentiometer for wire feed and for setting the
electrical current (6)
Use the potentiometer to set the welding voltage for the
MMA and LIFT TIG welding processes.
In the MIG welding process, you can use it to regulate
the wire feed.
Potentiometer for welding voltage (4)
Use the potentiometer for welding voltage to adjust the
welding voltage for the MIG welding process. For MMA
welding, set the arc force.

10. Start up

m Attention!
Always make sure the device is fully assembled
before commissioning!
Note: Different welding wires are required depending
on the application. Welding wires with a diameter of 0.6
– 1.0 mm can be used with this device.
Feed roller, welding nozzle and wire cross-section
must always match with one another. The device is
suitable for wire reels up to a maximum of 5000 g.
Use aluminium wire for welding aluminium and steel
wire for welding steel and iron.
Device setting for welding with inert gas
1 Select the MIG welding function (19) on the selec-
tion button (22).
2 a. Connect the earth clamp (32) to the negative
terminal (10) and lock the connector by turning it
clockwise.

b. Connect the polarity change cable (11) to the
positive pole (9) and lock the connector by turning
it clockwise.
c. Connect the hose assembly (27) to the connec-
tor (8) and fix it by tightening the nut at the con-
nection point.
d. Insert the appropriate welding wire and connect
the gas cylinder to the connector (1) on the back
of the device.
3 Connect the mains cable and activate the power
supply. After connecting the earth cable, the weld-
ing process can be started.
MIG welding
• Connect the earth clamp (32) to the workpiece to
be welded. Make sure that there is good electrical
contact.
• Rust and paint must be removed from the workpiece
at the welding point.
• Select the desired welding current to suit the weld-
ing wire diameter, the material thickness and the de-
sired penetration depth.
• Guide the torch nozzle (30) to the place on the work-
piece where welding is to be done and hold the weld-
ing shield in front of the face.
• Press the burner button (28) to feed the welding
wire. Once the arc is lit, the device feeds welding
wire into the weld pool.
• The optimum setting of the welding current can be
determined by trial and error on a test piece. A well
adjusted electric arc creates a soft, even buzzing
sound.
• If there is a rough or hard crackling sound, switch
to a higher power level (increase welding current).
• If the spot is large enough, guide the burner (29)
slowly along the desired edge. The distance be-
tween the burner nozzle and the workpiece should
be kept as short as possible (never larger than
10 mm).
• If necessary, swing the burner nozzle slightly in or-
der to enlarge the weld pool a little. For those with
little experience, the initial difficulty lies in creating a
stable electric arc. The welding current must be set
correctly for this.
• The penetration depth (corresponds to the depth of
the weld seam in the material) should be as deep as
possible but the weld pool should not drop through
the workpiece.
