resistance welding DC25 / UB25 •Ultra-fast closed-loop hybrid control provides extremelystable output waveforms in constant current, voltage and
power modes.•Exceptionally fast rise time permits shorter weld times, lesspart deformation, longer electrode life, and greater weld
strength with more part ductility.•Single phase operation permits easy installationand versatility of use.•Built-in monitor supports process loggingand data collection for SPC purposes.•Graphical monitor screen provides visual traceof energyover time for easy weld parameter
optimization. DC25,4000A maximum output.Versatile and accurate performance from a singlephase power supply.
UB25,50-1000A output.Superior low energy controlfor micro welding. Precision control for high reliability welding of miniature and micro-miniature parts The DC25 Linear DCwelding control is ideal for microjoiningapplicationswhich require exceptional control,fast risetimes,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,
resultingin less part deformation and stronger welds. This isextremelyimportant when welding heat sensitive parts suchas miniature batterycells or sensitive electronic devices.The UB25 (successor to the Unibond II) provides unsurpassedlevels of control for micro-miniature resistance welding.Requiring only single phase power,UB25 is a 1000 AmpLinear 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 themedical and automotive markets will benefit from UB25’s
precision low energy control. TYPICAL APPLICATIONS Battery tab to lithium ion cell
