Low Power Linear DC Spot Weld Control - UB29 - 1

Linear DC Welding Controls The DC29 Linear DC welding control is ideal for applications which require exceptional control, fast rise times, and high quality throughput. DC29 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 battery cells or sensitive electronic devices. DC29: 200-4000 amp output, versatile energy range with excellent control UB29: 5-500 amp output designed with high resolution for precise control for micro welding Straight forward rear panel I/O connections UB29 provides unsurpassed levels of control for resistance micro welding. Requiring only single phase power, UB29 is a 500 amp Linear DC control with 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 UB29’s precision low energy control. TYPICAL APPLICATIONS • Advanced closed-loop analog control yields repeatable and stable programmable waveforms • Extremely fast rise times permit shorter weld times, less part deformation, longer electrode life, and greater weld strength with more part ductility • Built-in monitor with graphical screen shows visual trace of energy over time, aiding in weld parameter optimization Battery tab to lithium ion cell Halogen lamp filaments Catheter guide wire assembly Air bag detonator module (squib wire) • Side mounted weld cables and compact unit size increase installation options • Single phase power input and simple I/O allows for easy setup and versatility of use RESISTANCE WELDING
