Before commissioning
Do not disassemble the collet body 63 and
i i
the gas nozzle 64.
When converting the torch to another elec-
trode diameter, please observe the following.
‰ The collet 62, collet body 63 and electrode 60 must have
the same diameter.
‰ The gas nozzle 64 must be matched to the electrode di-
ameter.
Connecting the ground cable
 Connect the component guide to the connection socket
component guide 5 and secure the cable by turning to
the right.
Fasten the ground clamp
Abb. 5: Fasten the ground clamp - Correct!
 Mount the ground clamp in the immediate vicinity of the
welding point such that the welding current canot find
its own way via machine components, ball bearings or
electrical circuits.
 Connect the ground clamp firmly to the welding
 bench or the workpiece.
Abb. 6: Fasten the ground clamp - Incorrect!
‰ Do not place the ground clamp on the welding machine
or the gas cylinder; otherwise the welding current will be
carried via the protective conductors and it will destroy
these.

Abb. 7: Shielding gas cylinder
 Secure the shielding gas cylinder 66,e.g. by using a se-
curing chain 67.
 Briefly open the gas cylinder valve 65 several times in or-
der to blow out any dirt particles present.
 Connect the pressure reducer 71 to the shielding gas
cylinder 66.
 Screw the shielding gas hose 72 onto the pressurereduc-
er 71 and open the shielding gas cylinder 66.
 Press keys 40 and 44 at the same time and for 2 seconds
(gas test) .
 Set the gas quantity with the setting screw 69 of the
pressure reducer („14.1 Guide value for inert gas quan-
tity" on page 38).
 The gas quantity is indicated on the flow meter 70.
