Welding Connections (only WUC-10, WUC-15)
The weld needs to be fully penetrating, but amperage and heat need to be minimised. We recommend flowing Argon gas
through the transducer during welding. This will help to cool the transducer. Prior to welding tubing to the transducer, it is
recommended that a few test welds be made.
WARNING!
■ Make sure the transducer is not connected to any other device, prior to arc welding.
■ Disconnect the transducer from any electrical device.
■ The operator is responsible for the material compatibility as well as correct handling, operation and mainte-
nance.
Prepare the transducer for use
1. Adjust the zero point (please refer to chapter Zero Adjustment).
2. Verify integrity of the weld or seal by appropriate helium leak-testing procedures.
3. Turn the gas flow ON then OFF, 10 times to remove any particles generated during installation. (The flow rate used should
at least equal the process flow specifications.)
MSM, Modular Surface Mount (only WUC-16)
Please observe the corresponding technical specifications, such as torques and mounting position of the contact compo-
nents.
