NOTICE
Do not use electrical components (ECM or ECM sen-
sors) or electronic component grounding points for
grounding the welder.

Illustration 35
Use the example above. The current
fl
ow from the welder to
the ground clamp of the welder will not damage any associated
components.
(1) Engine
(2) Welding electrode
(3) Keyswitch in the OFF position
(4) Battery disconnect switch in the open position
(5) Disconnected battery cables
(6) Battery
(7) Electrical/Electronic component
(8) Minimum distance between the component that is being welded
and any electrical/electronic component
(9) The component that is being welded
(10) Current path of the welder
(11) Ground clamp for the welder
5.
Connect the welding ground cable directly to
the part that will be welded. Place the ground
cable as close as possible to the weld in order to
reduce the possibility of welding current damage
to the following components. Bearings, hydraulic
components, electrical components, and ground
straps.
Note:
If electrical/electronic components are used
as a ground for the welder, or electrical/electronic
components are located between the welder ground
and the weld, current
fl
ow from the welder could
severely damage the component.
6.
Protect the wiring harness from welding debris
and spatter.
7.
Use standard welding practices to weld the
materials.

Severe Service Application
Severe service is the application of an engine that
exceeds the current published standards for that
engine. Perkins maintains standards for the following
engine parameters:
•
Performance such as power range, speed range,
and fuel consumption
•
Fuel quality
•
Operational Altitude
•
Maintenance intervals
•
Oil selection and maintenance
•
Coolant type and maintenance
•
Environmental qualities
•
Installation
•
The temperature of the
fl
uid in the engine
Refer to the standards for the engine or consult your
Perkins dealer or your Perkins distributor in order to
determine if the engine is operating within the de
fi
ned
parameters.
Severe service operation can accelerate component
wear. Engines that operate under severe conditions
may need more frequent maintenance intervals in
order to ensure maximum reliability and retention of
full service life.
