Principle of operation
6.4 Insert the welding wire roller
Open the flap of the welder and unscrew the nut from the
wire roll mandrel. Mandrel coils can be directly plugged
on, basket coils must be used when using basket coils.
Insert the roller so that the end of the wire is "left down"
(see Fig. 4). Fold the lever for the pressure adjustment to
the left to unlock the pressure roller, the pressure arm
folds up automatically. Insert the wire through the wire
entry into the wire inlet via the wire feed roller. Make sure
that the capillary tube 9 of the wire inlet nozzle is positio-
ned approx. 1 mm in front of the wire feed roller to en-
sure good wire guidance. Check the correct position of
the wire in the groove of the wire feed roller. Fold the
pressure arm down and lock it. Set the pressure correctly
with the print setup. (see Fig. 5)
6.5 Burner equipment
Current contact nozzle
The current nozzle transfers the electric current to the
wire electrode. Power nozzles are wearing parts and
must be replaced from time to time. Current nozzles are
available for various materials and wire diameters. For
aluminum special current nozzles are used.
Shield Cup
The protective gas nozzle has the task of directing the
protective gas emerging at the gas flow distributor to the
welding point. The protective gas nozzle must always be
kept clean and free of beads of sweat to guarantee pro-
tection of the welding bath from the ambient air. While
the conical gas nozzle concentrates the shielding gas on
the weld, the cylindrical gas nozzle covers a larger area.
Guide spiral
The wire guide spiral is pulled through the hose as-
sembly of the burner, in her the welding wire is passed to
the burner. The selection of the right wire guide spirals
depends on the material type and the wire diameter.
Souls are made of different materials and are available
for a variety of welding tasks. For aluminum, for ex-
ample, a special Teflon core must be used.
,
The accessories of the burner depend on the respective
welding task and must be adapted to it.
The standard delivery includes a SMB 15/3 m burner,
equipped with a flow nozzle (M 6 Ø 0.8 mm / 25mm).
CAUTION!
Before starting to feed the wire, make sure that the
welding machine is switched off and disconnected
from the mains.
NOTE!
The wire spool should still be able to be stopped by
hand while the drive is running. For aluminum, the
pressure should be as low as possible, but still allow
a safe transport of the wire.
