UB-4000A Linear DC Spot Welder

The UB-4000A linear DC resistance welding control is a 200-4000 amp linear DC control with four feedback modes designed to adapt to part and process variables. Weld energy may be programmed in current, voltage, power, or V-A, in increments as short as .01 milliseconds making this spot welder ideal for small applications in the electronic component and battery pack markets.

A successor to model DC25, and built in the USA, the UB-4000A 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-4000A replaces the DC25 in the majority of applications, please consult AMADA WELD TECH for suitability of replacement prior to purchase.
