Kjellberg Q Series

"Custom Fabricated CNC Plasma Cutting Systems To Meet Your Everyday Needs"

Available April 2023! Q4500

The Q 4500 plasma cutting system is the most powerful system in the Q-Series. It combines precise plasma cutting and marking at the best level with a maximum of 450 A cutting current. It enables the costumer to make precise plasma cuts up to 120 mm. High cutting speeds reduce costs and increase efficiency. This generation of plasma cutting systems is the result of intensive Kjellberg research and development in Kjellberg’s 100-year history. The new, digitised Q plasma system series sets forward-looking standards in quality and connectivity.

The specially developed browser-based operator interface Q-Desk provides real-time process data and information of all plant components on any standard device and location-independent. The user benefits from extensive information enabling him to plan and execute a variety of maintenance tasks as guided by the system.

Plasma Cutting 4.0

The new, pioneering Q-Series from Kjellberg combines precision plasma cutting at an exceptional level with the complex requirements of digitized production.

Thanks to the modular design, the machine performance of the Q 3000 plus can later be upgraded and, thus, adapted to the your requirements. The specially developed browser-based operator interface Q-Desk provides real-time process data and information of all plant components on any standard device and location-independent. The user benefits from extensive information enabling them to plan and execute a variety of maintenance tasks as guided by the system.

This generation of plasma cutting systems is the result of intensive research and development work by Kjellberg and a landmark in the 60 years of Kjellberg’s plasma history. The new digital plasma series Q sets pioneering standards regarding quality and connectivity.
