WELDING ON MACHINES AND ENGINES WITH ELECTRONIC CONTROLS

Welding on Machines and Engines with Electronic Controls
Proper welding procedures are necessary to avoid damage to the electronic controls,
drivetrain bearings or other components. The following steps should be followed when
welding on a machine or an engine with electronic controls.
Proper welding procedures must be followed to prevent damage to the machines electronic
controls and the machine or attachment bearings. Failure to comply may result in damage to
machine.
If welding on an attachment, remove it from the machine before welding. This will prevent
damage to machine's electronic components and bearings. Proper grounding of the attachment
must be done before welding.
1. Turn off the engine.
2. Turn the battery disconnect switch to the OFF position, or remove the negative
battery cable from the battery.
3. Clamp the ground cable from the welder to the component that will be welded.
Place the clamp as close as possible to the weld. Make sure that the electrical path
from the ground cable to the component does not go through any bearing. Use this
procedure in order to reduce the possibility of damage to the following:
• Drive train bearings
• Hydraulic components
• Electrical components
• Other components of the machine or attachment
Do NOT use electrical components, ECM, ECM sensors or electronic component grounding
points to ground the welder. Failure to comply may result in damage to machine or Grapple.
4. Protect any wiring harnesses from the debris which is created from welding. Protect
any wiring harnesses from the splatter which is created from welding.
5. Follow standard welding procedures.
