W0111A
Whenever carrying out a welding operation on the undercarriage or upper-structure carriage as authorized by NEW
HOLLAND CONSTRUCTION and in accordance with their instructions, disconnect the batteries, disconnect the al-
ternator B+, D+ terminal wires, and the instrument cluster connector and connect the welding apparatus ground cable
to the component on which the welding operation is to be performed. Never connect the welding apparatus to the
undercarriage when welding on the upper-structure (or vice-versa). Never connect the welding apparatus ground to
a component of the hydraulic system.
To avoid damage to the electronic/electrical systems,
always observe the following:
• Never make or break any of the charging circuit con-
nections, including the battery connections, when the
engine is running.
• Never short any of the charging components to ground.
• Make sure to set the battery disconnect switch to O po-
sition (OFF position) in advance or cut-off the connec-
tion of the ground cable when executing arc welding to
the machine.
• Always disconnect the negative cable from the battery
when charging the battery in the machine with a battery
charger.
NOTICE: position the welder ground clamp as close to the
welding area as possible. If welding in close proximity to
a computer module, then the module should be removed
from the machine. Never allow welding cables to lay on,
near or across any electrical wiring or electronic compo-
nent while welding is in progress.
NOTICE: if welding must be performed on the unit, either
the machine, the battery ground cable must be discon-
nected from the machine battery. The electronic monitor-
ing system and charging system will be damaged if this is
not done.
