AMADA - Linear DC Welding Controls - UB Series

AMADA - Linear DC Welding Controls - UB Series

Transistor direct current power supplies (also called “Linear DC”) produce much the same results as the high frequency inverter by using a high number of power transistors as the direct energy source. This technology provides clean, square wave forms with extremely fast rise time. Used primarily in constant voltage feedback control, transistor DC power supplies are effective in thin foils and fine wire welding applications and for extremely short welds.

The UB-4000A Linear DC welding control 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 (5-500 amps), and UB-1500A (15- 1500 amps) are Linear DC controls with feedback modes designed to adapt to part and process variables. These power supplies 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.

Available Models

AMADA Low Power Linear DC Micro Spot Welder, UB-500A

The UB-500A linear DC micro spot welder provides unsurpassed levels of control for resistance micro spot 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 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
