UB-500A Low Power Linear DC Micro Spot Welder

UB-500A Low Power Linear DC Micro Spot Welder

Formerly known as UB29. Replaces UB25.*

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

What is micro spot welding? Generally speaking, if you are welding parts with thicknesses of 0.0005 in to 0.08 in you are micro spot welding.

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 spot 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, and built in the USA, the 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.

Four control modes: current, voltage, power and V-A (voltage-current)

Single phase input

Compact size

Dual pulse schedules

Precisely controlled repeatable waveform

Very fast rise time

*UB-500A replaces the UB25 for current ranges from 5 – 500 A. Please consult AMADA WELD TECH for suitability of replacement prior to purchase.
