The UB-4000A - Linear DC Spot Welding Control with Built‑in Monitor is ideal for applications which require exceptional control, fast rise times, and high quality throughput. UB-4000A 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.
UB-500A provides unsurpassed levels of control for resistance micro welding. Requiring only single phase power, UB-500A 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 UB-500A’s precision low energy control.
