Note: Personal breathing protection should be worn by the personnel that are welding. Personal breathing protection will prevent fumes from entering the lungs of the person that is welding. Use a 1U-8088 Type H Respirator for breathing protection.
Proper Welding Procedure on Machines and Engines with Electronic Controls
Proper precautions are necessary to prevent damage to electronic controls. When you weld on a machine with electronic controls, use the steps that follow:
- Turn off the engine. Put the key start switch in the OFF position.
- If the machine has a battery disconnect switch, open the switch. If the machine does not have a battery disconnect switch, disconnect the negative battery cable at the battery.
- Connect the ground cable for the welder directly to the actual machine component that will be welded. Attach the clamp for the ground cable as close as possible to the area that is being welded in order to reduce the chance of damage from welding current to the components that follow: bearings, hydraulic components and electrical components.
Note: Do Not use ground points for electronic components as a ground point for the welder.
- Protect the wiring harnesses from the weld splatter.
