Features

• Closed loop technology

Industrial inverters produce consistent, reliable welds with optimal nugget formation, superior joint strength and excellent surface appearance.

• Fine heat input control

Short weld times and millisecond control provide more accurate welds, resulting in a smaller heat affected zone (HAZ), and facilitating longer industrial electrode life than conventional Ac welding technology. Markless welding also becomes possible.

• Control mode flexibility

Select which mode fits the application, with fast rise times for conductive material or finer control for resistive material. Constant Power feedback mode helps to break up surface oxides and extends electrode life, especially when welding coated steels or aluminum.

• Reduce operating costs

Inverters draw less energy from the incoming power line than single phase AC industrial welders. This leads to greater cost savings and power efficiency in today's modern manufacturing plants.

• Automation-ready

Inverter industrial transformers are smaller than AC transformers, making them well suited for automation and robotics.

• Process control

The ISA's stable welding control and built-in monitoring deliver wider process windows and traceability, and fulfill documentation requirements for many of today's industries.

• Improve weld reliability

Inverters have greatly reduced secondary inductive losses, which eliminate many welding problems associated with AC welding technology.
