Low Power Linear DC Weld Control - UB25 - 1

Linear DC Welding Controls Precision Control For High Reliability Micro Welding UB25, 50-1000A output. Superior low energy control for micro welding. DC25, 4000A maximum output. Versatile and accurate performance from a single phase power supply. The DC25 Linear DC welding control is ideal for micro welding applications which require exceptional control, fast rise times, and highest quality throughput. 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 which is extremely important when welding heat sensitive parts such as miniature battery cells or sensitive electronic devices. 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. 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. TYPICAL APPLICATIONS KEY FEATURES • 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 Battery tab to lithium ion cell Halogen lamp filaments • 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 Catheter guide wire assembly Air bag detonator module (squib wire) RESISTANCE WELDING
