INTRODUCTION
Safety rules (Weld works)
WARNING
Avoid injury!
When welding, always wear proper protective equipment and welding clothing. All persons in the
work area must, at minimum, wear welding goggles. Never look directly at the welding arc without
welding eye protection.
Failure to comply could result in death or serious injury.
W1178A
NOTICE:
Repair works with welding must be performed by a qualified and experienced welder. Appropriate safety
regulations should be followed by the personnel involved in the work. The time to perform welding operations depends
on the quality and precision of the work. Never make modifications on the machine.
To perform welding operations on the machine
(authorized and in accordance with CASE
CONSTRUCTION recommendations), proceed as
follows:
• Identify all points of fracture or cracking, and the areas
in which welding is required.
• Thoroughly clean the areas involved.
• Remove all paint. Inspect the parts with liquid penetrant
or a magnetic tool for particles.
• Shut down the engine. Place the ignition key in the
“OFF” position to shut down the engine.
NOTICE:
After you shut down the machine, wait at least
8 min
to shut down the battery cables or the master
switch (if equipped). This time is necessary so that the
engine’s electronic system (if equipped) can store the
settings data in the electronic module.
• Disconnect the batteries and the wires from terminals
D+ and B+ of the alternator.
• Disconnect the electrical wiring harnesses from the
transmission control modules and from the engine.
• Connect the ground cable of the welding machine to the
component to be welded.
• Always connect the welding equipment to the frame that
is being welded.
• Never connect the welding equipment ground to a com-
ponent of the hydraulic system.
• Avoid welding at low temperatures, e.g., below
16 °C
. If
necessary, warm up the part involved prior to welding.
• Remove the paint from all surfaces before heating or
welding. Painted surfaces can generate toxic gases
when heated or welded.
• Use appropriate masks or protective goggles.
• Wear appropriate gloves and protective equipment.
• Disconnect the connectors from all control modules of
the machine.
