Welding Control Systems

ARO Controls is the electronics division of ARO and is a world-renowned specialist in resistance weld controls. Located next to ARO headquarters, ARO Controls’ state-of-the-art facilities have been specifically developed for the design and manufacture of weld controls.

ARO’s continuous programme of research and development embrace the latest technologies to deliver high performance, high quality products at the best possible prices. 

ARO offers a large range of integrated welding controllers equipped with the latest technology of welding controls. From the standard AC-DC cabinets until the advanced concept cabinets (auto- adaptive), ARO ensures simple yet complex solutions most adapted to your needs. The integration of ARO guns and cabinets has created systems which noticeably improve the method of resistance welding in each application.

Adaptive MFDC welding controllers

Through extensive research and development, ARO has designed an intelligent and efficient control system known as Adaptive Welding (AW). This revolutionary system automatically compensates for process variations to guarantee a far superior weld quality.

AC Welding Controllers

ARO has, for many years, been recognised as a specialist in AC welding. ARO’s proven Control System with its user-friendly and robust interface has been incorporated into many thousands of welding systems around the world.

iBox Servo Welder Controller

For servo-actuated guns and machines, iBox centralises all resistance welding parameters into one process controller! Programming and monitoring of all welding parameters (time, current, force) are regrouped in just one cabinet, clearly delimiting responsibilities between the robot and the welder. As a result, almost any 6-axis robot (pneumatic welding, handling, refurbished, etc.) can manage a servo weld gun with just a small modification to its application software. Similarly, any PLC can drive a servo weld gun or servo machine.

Welding Software


ARO weld controllers can be networked to a central computer running the ARONET software. All the functions of each and every welder can then be accessed in real time on the central computer.
