Product Description:

The PSI63C0.733-L1is a medium-frequency inverter designed by Bosch Rexroth as part of their dedication to improving the practical application of resistance welding systems in automobile manufacture. The inverter is a flexible device that is adaptable to any type of resistance welding, including spot welding and the more common seam welding. The flexibility of this product is majorly due to its integrated and sophisticated weld timer which is responsible for the control of all programmed welding schedules. The frequency inverter offers more control and quality for different operations. It reduces the expulsion period by decreasing welding current or time. It also improves the lifespan of the electrode tips by lowering its mechanical and thermal load.

The adaptive current and voltage control feature also ensures enhanced stability and improved spot welding output. The PSI63C0.733-L1offers numerous features to help improve its efficiency. There is a BOS 5000 operator interface present on the housing of this product, this interface is used to connect the inverter to a local PC where easy programming, diagnostics, and smooth operation can be carried out. The inverter is also able to carry out reliable monitoring functionality which focuses on the inverter system and its operating conditions.

The PSI63C0.733-L1has a 3-phase AC input unit, and the rated voltage is between 400 and 480 volts. The inverter has a maximum primary current of 800 amperes and a maximum secondary current of 36,000 amperes. This is suitable for steel applications. The design and function are best for connecting welding transformers like the PSG 3100 product series. The PSI63C0.733-L1maintenance requirement includes checks to ensure a tight fit of all connecting cables and terminals at regular intervals. The inverter has an air coolant system which will require regular cleaning to prevent the accumulation of dust which can affect its performance standard. The battery should also be checked or replaced at intervals.
