The UF40 inverter spot welder delivers superior welding

control for a wide range of microjoining applications.

When paired with the TR4000 transformer this unit is

capable of a maximum output of 4500 Amps, making it

ideal for most resistive and conductive welding applications.

It operates in constant current, voltage or power feed-

back modes and is also capable of welding in a combo

mode (current and voltage) to address even the most

challenging application or process conditions.

It can address a wide range of applications including sensitive

medical device components, solar cells, automotive electronics,

battery tabs, battery pack assembly and more!
