UB-4000B Linear DC Micro Spot Welder

Successor to UB-4000A

The UB Series is our most advanced resistance welding power supply family to date, retaining the proven pulse-control architecture of earlier generations while introducing the all-new Flex Pulse Mode for virtually unrestricted pulse shaping.

With a max output of 4000 A, UB-4000B features closed-loop feedback control of current, voltage, or power which enables it to deliver superior results for the kinds of precision welding applications commonly found in the medical device, aerospace, automotive, battery, and other industries.

Enhanced I/O and modern communication protocols like RESTAPI and MQTT make this welder ideal for automation as well as benchtop manufacturing
