UB-500A Low Power Linear DC Micro Spot Welder

The UB-500A linear DC micro spot welder provides unsurpassed levels of control for resistance micro welding and thermocompression bonding.

With a max output of 500 A, UB-500A is a linear DC control with four feedback modes designed to adapt to part and process variables. This micro welding machine 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.

A successor to model UB25, UB-500A features a variety of updates, including greatly improved waveform control and faster rise time, as well as new side-mounted buss bars with threaded inserts for mounting weld cables, simplified rear panel I/O connections, and an on/off switch on the front for increased convenience.
