Arc Machines

What Arc Machines does

Arc Machines (AMI), founded in 1976 and headquartered in Pacoima, California, is a specialty manufacturer of automated orbital GTAW (TIG) welding systems serving mission-critical industrial applications. The company designs and produces a portfolio of weld heads including the Model 6 (tube-to-tubesheet), Model 13 (elbow/elbow-to-elbow), and Model 94 (ID spiral cladding), along with the M317 power supply, M317-CW cooling unit, and a Digital Viewing System. These products are engineered for environments where weld integrity is regulated and failure is non-negotiable, including semiconductor fabrication (vacuum lines, gas cabinets), pharmaceutical process piping, aerospace hydraulic and fuel systems, food and dairy hygienic lines, and nuclear and power generation installations. AMI offers custom solution development for restrictive or specialized applications such as naval installations and unique elbow geometries.

Commercially, AMI operates as a wholly-owned brand subsidiary under ESAB Corporation, distributing exclusively through ESAB's global authorized distributor network rather than direct-to-end-user sales. Pricing is quote-based and not publicly disclosed, reflecting the enterprise capital equipment nature of the product and the highly engineered, often customized configurations sold into regulated industries. Revenue is generated primarily through hardware sales of orbital welding systems and peripheral equipment, supplemented by custom engineering services for specialized applications. The go-to-market is enterprise field sales supported by ESAB University training, technical documentation, webinars, and industry-specific landing pages, with marketing emphasis on code compliance, traceability, and weld-quality outcomes rather than price competition.

AMI's three named founders — M.E. Gedgaudas, V.K. Fukumoto, and L.V. Reivydas — established the firm nearly fifty years ago, and the company has built a recognized installed base in regulated verticals globally. The relationship with ESAB provides distribution, service, training, and brand reach that smaller orbital welding competitors cannot match, while AMI's specialization in automated orbital GTAW provides ESAB with a defensible niche in process-critical welding applications. Limited public financial disclosures and the niche industrial nature of the business mean that specific revenue, headcount, and order book figures are not part of the available record.

Core offering

Arc Machines (AMI) designs and manufactures automated orbital GTAW (TIG) welding systems, including proprietary weld heads, power supplies, cooling units, and digital viewing systems used for tube-to-tubesheet, pipe, and cladding welding. The systems are sold primarily to enterprise customers in semiconductor, pharmaceutical, aerospace, nuclear, and power generation industries requiring code-compliant, high-purity, and fully traceable welds. AMI also offers custom solution engineering for specialized and restrictive welding applications.

Product overview

AMI (Arc Machines) is a brand under ESAB Corporation specializing in automated orbital TIG welding systems. The product portfolio consists of weld heads (Model 6, Model 94, Model 13), supporting equipment (Cooling Unit M317-CW), and visualization systems (Digital Viewing System). These products work together as integrated orbital welding solutions: weld heads perform precision GTAW (TIG) welding, the cooling unit maintains optimal operating temperatures, and the digital viewing system enables real-time monitoring of the welding arc and molten metal. The systems are designed for critical industries including semiconductor, pharmaceutical, aerospace, nuclear, and food/dairy applications requiring high-purity, code-compliant welds.
