Miyachi Unitek UB25

Linear DC Welding Control. The UB25 provides unsurpassed levels of control for micro-miniature resistance welding. Requiring only single phase power, UB25 is a 1000 Amp Linear DC control with three feedback modes designed to adapt to part and process variables. Ultra-fast closed-loop hybrid control provide extremely stable output waveforms in constant current, voltage and power modes. Exceptionally fast rise time permits shorter weld times, less part deformation, longer electrode life, and greater weld strength with more part ductility. Single phase operation permits easy installation and versatility of use. Built-in monitor supports process logging and data collection for SPC purposes. Graphical monitor screen provides visual trace of energy over time for easy weld parameter optimization. 115V, 50/60 Hz, 10A, CE. Setting Ranges: Current: 5A - 1000A. Voltage: 0.01V - 4.9V.
