Welding Connections (only WUD-20, WUD-25)
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.
