The AMADA IPB-5000B DC Inverter Welding Power Supply is engineered for high-precision spot welding and fusing, offering advanced control and monitoring capabilities. It features four selectable control modes for optimal weld quality: secondary constant current, secondary constant voltage, a combination of both, and secondary constant power control. A key technical highlight is its robust GOOD/NO GOOD determination system, incorporating both Comparator and Envelope functions. The Comparator allows setting upper and lower limits for up to four parameters—current, voltage, power, and resistance—to ensure process consistency and alert for deviations. The Envelope feature dynamically monitors waveforms to guarantee consistent resistance change rates. An optional displacement measurement function further enhances precision by measuring electrode penetration and stopping welding at a preset displacement value. The IPB-5000B significantly reduces weld current ripple to one-third of conventional models, maintaining a low peak current and constant current for superior weld stability. Key specifications include a 5kHz primary frequency, a maximum output current of 4000A (with IT*-780*6 transformer), and a rated capacity of 17.4kVA. It supports 127 weld schedules and a current setting range of 0.40 to 4.00 kA. Operating on three-phase 200-240V AC or 380-480V AC, this compact unit (172W x 470D x 269H mm, 15 kg) is ideal for demanding manufacturing environments requiring consistent, high-quality welding results.
