11.6 Connecting the ground cable
 Connect the ground cable to the free minus or plus 8
socket and secure the cable by rotating it clockwise.
Fastening the ground clamp
Abb. 5: Attaching the ground clamp - Correct!
 Fasten the grounding clamp in the immediate vicinity
of the welding area, so that the welding current can-
not seek its own return path across machine parts,
ball bearings or electric circuitry.
 Connect the ground clamp rmly to the welding bench
or the workpiece.
Abb. 6: Attaching the ground clamp - Wrong!
 Do not place the ground clamp on the welding ma-
chine or the gas cylinder; otherwise the welding cur-
rent will be carried via the protective conductors and
it will destroy these.
11.7 Connecting the power supply
The machine is suitable for operation on the mains sup-
ply or on a current generator.
 Plug the mains plug into the appropriate socket.
The mains voltage and tolerance as well
as the fuse protection must correspond to
the technical specications (see Technical
Specications).
11.5 MIG welding process
A wire feed case (optional) is required for
MIG welding.
The operations required may differ depend-
ing on the version and the conguration of
the wire feed case!
Please observe the wire feed case operat-
ing manual!
 Connect the welding cable of the wire feed case to
the connection socket minus or plus 8 of the power
source (X 350).
 Connect the control cable of the wire feed case (with
adapter if necessary) to the remote control connec-
tion socket (7) of the power source (X 350). (if tted)
 Equipping the wire feed case. (See wire feed case
operating instructions)
