Body and Frame: Service Precautions

Welding Precautions
1. If welding must be done on a frame, make sure the following requirements are met:
- If the frame is attached to the vehicle, the battery ground cable must be disconnected before using any electrical welding equipment.
- Do not use gas welding equipment. Arc welding is the only approved method.
- Use a temperature-indicating crayon to make sure that the temperature does not exceed 750°C (1400°F).
- Install new spot-welded components by spot welding where possible. If spot welding is not possible, use puddle welding.
