Do NOT use electrical components (ECM or sensors) or electronic component grounding points for grounding the welder.
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 to reduce the possibility of damage to the following components:
Bearings of the drive train
Hydraulic components
Electrical components
Other components of the machine
Protect any wiring harnesses and components from the debris and the spatter which is created from welding.
Use standard welding procedures to weld the materials together.
