Product Description

The PSI6100.357-L1 is a state-of-the-art frequency inverter built to provide accurate welding control in industrial environments. This frequency inverter serves as the power supply unit for a programmable welding time integrated with it into the same housing unit. It is a product of Bosch Rexroth Indramat that is able the support major types of welding applications in the environment. This product forms a fully functioning welding station by combining with a weld transformer and electrode. The compatible weld timer used with this inverter is the PSG 3000 weld transformer. During the operation of this product, the inverter receives a 50/60 hertz mains alternating current, which is rectified by a bridge-connected rectifier; the resulting direct current generated connects a transistorized H-bridge alternatingly to the welding transformer at a clock frequency of 1 kilohertz. Compared to other inverters that function at a lower frequency, the current regulation system of this product is significantly faster and more precise.

The PSI6100.357-L1 frequency inverter is able to provide the connected weld transformer with protection against over-heating; this protection is through a thermostatic switch which signals any sign of overload in the transformer to the weld timer on the inverter. The weld timer then outputs a “Thyristor unit fault” message to alert the operator. The operation system ensures that the quality of the welding system is preserved over time.

The PSI6100.357-L1 frequency inverter reduce the weight of the welding transformer, this is majorly due to the higher operating frequency of the inverter, the iron content and the volume are also significantly reduced. The ability of this product to maintain a constant-current control compensates for the changes in sheet resistance within the weld time and helps to guarantee a constant welding result.
