Proper welding procedures are required to avoid damage to electronic controls, sensors and associated components.
The component should be removed for welding if possible.
The following procedure must be followed if the component must be welded while installed on equipment with
electronic controls. This procedure will minimize the risk of component damage.
WARNING
Do not ground the welder to electrical components such as the control ground or
sensors. Improper grounding can cause damage to electrical components. Clamp
the ground cable from the welder to the component being welded. Place the clamp
as close as possible to the weld to reduce the possibility of damage.
1. Stop the engine. Turn the key switch to the OFF position.
2. Disconnect the negative (-) battery cable from the battery.
