MACHINE GROUNDING
Because this portable engine driven welder or genera-
tor creates its own power, it is not necessary to con-
nect its frame to an earth ground, unless the machine
is connected to premises wiring (your home, shop,
etc.).
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power,
must:
a) be grounded to the frame of the welder using a
grounded type plug
or
b) be double insulated
When this welder is mounted on a truck or trailer, the
machine grounding stud must be securely con-
nected to the metal frame of the vehicle.
In general if the machine is to be grounded, it should
be connected with a 10mm
2 (#8 AWG) or larger cop-
per wire to a solid earth or to the metal framework of a
building which has been effectively grounded. The
Australian and New Zealand Wiring Standards lists a
number of alternate means of grounding electrical
equipment. A machine grounding stud marked with
the symbol is provided on the front of the welder.
DO NOT GROUND MACHINE TO A PIPE WHICH
CARRIES EXPLOSIVE OR COMBUSTIBLE
MATERIAL.

WARNING
CAUTION
• Loose connections will cause the output studs to
overheat and the studs may eventually melt.
• Do not cross welding cables at output stud connec-
tion. Keep isolated and separate from one another.

Lincoln Electric offers a welding accessory kit with
16mm
2 (#6 AWG) welding cables. See the ACCES-
SORIES section of this manual for more information.
For more information on welding , see WELDING
OPERATION in the OPERATION section of this man-
ual.
Cable Installation
Install the welding cables to your OUTBACK™ 185
(AU) as follows. See Figure A.1 for the location of
parts.
1. The petrol engine must be OFF to install welding
cables.
2. Remove the 1/2-13 flanged nuts from the output
terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. Normally, the electrode
cable is connected to the positive (+) output stud.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is securely connected to the work
clamp and cable.
6. Check and tighten the connections periodically.
