CAUTION
Follow these rules if welding is done on the vessel after installation of the Load Disc.
The electrical current of the welder may pass through the Load Disc, causing damage to the
transducer and possibly to the signal processor. To avoid damage, follow these precautions:
1. Disconnect the Load Disc cables from the signal processor.
2. Ground the welder as close to the welding joint as possible. The welding ground must be
between the Load Disc and the weld joint to prevent the welding current from going through the
Load Disc to earth ground.
Note
High temperatures can damage the Load Disc. If you are welding in the vicinity of a
Load Disc, monitor the temperature of the metal adjacent to the Load Disc. If it becomes too hot to
touch, stop welding immediately and remove the Load Disc before continuing. Prior to reinstalling
the Load Disc, verify that no damage has occurred by referring to the measurement procedures in
Troubleshooting, Appendix C.
