Arc Machines

In 1976, Mindy Gedgaudas and Lou Reivydas founded Arc Machines, Inc. (AMI), later joined by Vic Fukumoto. They entered the specialized world of automated orbital welding, a technique first developed in the 1960s for the X-15 rocket plane program. The company's focus was clear: design and manufacture high-quality, durable automated welding systems. This equipment—power sources, controllers, and weld heads—enables highly repeatable and precise welds, which are critical in demanding industries. Their systems quickly became essential for sectors where weld integrity is non-negotiable, such as aerospace, semiconductor manufacturing, nuclear, and pharmaceuticals. For example, their technology was used for repairs on the space shuttle's external fuel tank and in the construction of the Large Hadron Collider at CERN. The business wasn't just about a single product but about creating a complete system that ensured precision for everything from tiny tubes in a cleanroom to massive pipes in a power plant. The company grew steadily, establishing itself as a gold standard in its niche. After decades of private operation and backing from firms like Marwit Capital and Praesidian Capital, a major event occurred. In January 2017, Arc Machines was acquired by ESAB, a global leader in welding and cutting products. The acquisition integrated AMI's specialized technology into ESAB's broader portfolio, allowing the brand to continue its work under a larger industrial umbrella.
