What CLOOS does

CLOOS is a German welding technology and automation company operating as Carl Cloos Schweißtechnik GmbH, with roots dating to 1919 and a group turnover of €230 million. The company employs over 1,000 people across 16 global subsidiaries and 10 production sites, serving manufacturing industry customers worldwide with welding equipment and automation solutions.

The company's product portfolio spans manual welding equipment (power sources, wire drives, torches), collaborative robot welding, fully automated welding systems (including the QIROX robotics platform and QIROX WeldExperT Compact Cells), and customized concept systems. Its technology stack is anchored by proprietary assets: the modular QIROX robotics platform, the C-Gate IIoT platform with an Ultimate Module extension, CLOOS QNECT connectivity solution, the QIROX software suite (RoboPlan, EasyWeld, Quick Weld Programming, RoboScan), and the TANDEM+ advanced 3-wire MIG/MAG welding process. CLOOS claims over 90% vertical integration in main component production and 53% of its workforce trained internally, supporting process expertise and customization capability.

CLOOS generates revenue primarily through hardware sales (welding equipment and automated systems), aftermarket services (spare parts, retrofit, maintenance, repair, validation), professional training via CLOOS Academy, and digital/software solutions (C-Gate, QIROX software). The company operates an enterprise field sales go-to-market, selling directly to manufacturers through regional subsidiaries and website channels, with quote-based pricing on industrial systems. Named customers include AGCO, Fendt (an AGCO brand), and HUCH in agricultural equipment and industrial manufacturing verticals.

Direct peers

• Kemppi: Finnish private welding equipment manufacturer offering power sources, torches, and robotic welding solutions. Comparable scale and European heritage with similar focus on welding automation and digital integration.
• Fronius International: Austrian private company and one of CLOOS's closest direct peers — manufactures welding power sources, robot welding systems, and solar/charging solutions. Highly comparable in vertical integration approach, European manufacturing base, and welding automation focus.
• Lincoln Electric: US-listed global leader in welding and cutting products, offering welding equipment, automation, and consumables. Direct competitor to CLOOS across manual and automated welding, with overlapping enterprise customer base in heavy industry.
• ESAB Corporation: US-listed global welding and cutting equipment manufacturer with a comprehensive portfolio including robotic welding cells. Direct competitor to CLOOS in industrial welding equipment and automation.
• Panasonic Welding Systems: Japan-based welding equipment and robotics business of Panasonic, offering welding power sources and robot welding cells. Direct competitor in automotive and industrial welding automation.
• Miller Electric (ITW): US-based welding equipment manufacturer (division of Illinois Tool Works) producing power sources, wire feeders, and automated welding systems. Direct competitor in both manual and automated welding segments.
• OTC Daihen: Japanese manufacturer of welding power sources, industrial robots, and automated welding systems. Direct peer with overlapping product portfolio in MIG/MAG, TIG, and robotic welding.

Broad incumbents

• KUKA: German-based global robotics and automation company offering welding cells and integrated production systems. German peer with comparable industrial heritage but broader portfolio spanning non-welding automation.
