Pro-Fusion by Elderfield & Hall

What Pro-Fusion by Elderfield & Hall does

Pro-Fusion by Elderfield & Hall is a privately held U.S. precision arc welding equipment manufacturer founded in 1999 under the legal entity Elderfield & Hall, Inc. The company designs and sells a portfolio centered on Micro-TIG and Micro-Plasma welding power supplies (notably the dual-process Dual-Arc 82, capable of arc starting at 0.1 amp), complementary automation modules including the Arc Voltage Controller with Arc Gap Setter (PF-AVC) and the WELD-PRO HMI weld controller, precision welding lathes for circumferential welds, plasma welding torches covering 0.1–500 amps, and the Sharpshooter line of tungsten electrode grinders distinguished by enclosed dust extraction for radioactive thoriated tungsten. The product set is sold both as standalone equipment and as integrated welding systems with Modbus connectivity for robotic and lathe integration.

Revenue mechanics are primarily one-time equipment sales through a quote-based enterprise model, supplemented by a transactional e-commerce layer for accessories and consumables (diamond grinding wheels, collets, dust bags, replacement filters) and a consumables line of pre-ground tungsten electrodes sold directly and via the I-Tungsten.com channel. A free in-house weld lab provides procedure development, sample welds, weld-speed estimates, and prototype parts, acting as both a presales technical resource and a switching-cost mechanism for qualified customers. Indicative pricing for the Sharpshooter TSS-1 is $2,520 and TSS-2 $2,820, with HEPA dust extractors and work cabinets ranging $460–$999; larger items (Plasma Console 400 HFP, AVC, WELD-PRO HMI) are quote-based.

The customer base spans medical device manufacturing, aerospace and defense, semiconductor and pharmaceutical production, automotive, tube mill operations, and food and dairy, with named enterprise and government accounts including the U.S. Air Force, U.S. Marines, U.S. Navy, Boeing, GE Aircraft, and Pratt & Whitney. Distribution is direct (website, phone, fax) in the U.S., with a secondary Chicago office and a European distribution partnership through Qualitas Technology Ltd. The company maintains an active FABTECH trade show presence and a content-driven marketing approach via technical articles and a quarterly newsletter.
