Low Power Linear DC Weld Controls - Miyachi - #1

Text version of the page

• Ultra-fast closed-loop hybrid control provides 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. resistance welding DC25 / UB25 Linear DC Welding Controls DC25, 4000A maximum output. Versatile and accurate performance from a single phase power supply. UB25, 50-1000A output. Superior low energy control for micro welding. Precision control for high reliability welding of miniature and micro-miniature parts The DC25 Linear DC welding control is ideal for microjoining applications which require exceptional control, fast rise times, and highest quality throughput. The DC25 requires only single phase input power and can output up to 4000 Amps. Ultra-fast rise times permit short overall weld times, resulting in less part deformation and stronger welds. This is extremely important when welding heat sensitive parts such as miniature battery cells or sensitive electronic devices. The UB25 (successor to the Unibond II) 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. This power supply should be used for smaller applications where closed-loop feedback control and fast response times are required. Safety critical applications such as those found in the medical and automotive markets will benefit from UB25’s precision low energy control.
