Connecting the ground cable

 Connect the ground cable 2 to the ground connection 1
secure in position by turning clockwise and connect the
ground clamp 26 to the welding bench or workpiece with
a good electrical connection.

Fastening the ground clamp

Fig. 6: Correct
 Attach the ground clamp 26 immediately beside the weld-
ing point so that the welding current will not try to find its
own return path through machine parts, ball bearings or
electric circuits.
 Connect the ground clamp firmly to the welding bench or
the workpiece.
Fig. 7: Incorrect
‰ Do not place the ground clamp on the welding machine or
the gas cylinder; otherwise the welding current will be car-
ried via the protective conductors and it will destroy these.

Insert the welding wire coil

Danger of injury and fire caused by glowing
welding wire or parts!
Wire protruding from the welding wire coil can
cause short-circuits with the side wall or the
base of the unit.
When inserting the welding wire coil take care
that it is correctly wound up and that the wire
does not protrude.
Set the wire brake so that, when the torch
switch is released, the welding wire coil does
not run on.
 Open the cover on the machine or wire feeder and release
the retaining nut 43 on the decoiler mandrel 41.
 Place the welding wire coil on the decoiler mandrel and
ensure that the carrier mandrel 40 locks in position.
 For small welding wire coils, use an adapter (order number
620.9650.0).
 Set the wire brake 42 so that, when the torch switch is re-
leased, the welding wire coil just does not run on.

Thread the wire electrode in

 Unscrew the contact tip of the torch 19.
 Open the side plate or wire feed case.
 The diameter of the wire electrode must agree with the
legible embossed figure on the wire feed rollers 48.
 Swing the tilt levers 46 to the side and thread the wire elec-
trode through the inlet nozzle 47 and central socket 11.
