Haun Welding Supply Durable and Progressive Haun Welding Supply is a 4th generation business that services most of New York State, Vermont, Connecticut, New Hampshire and Northern Pennsylvania. We distribute welding supplies, industrial supplies and compressed and liquid gases through 22 stores located within these regions. We also provide welding training and repair services. Industries that are serviced by Haun include construction, fabrication, manufacturing, commercial, medical, laboratories, education and homeowners. One of the major segments served by the company is gas supply. To strengthen and offer additional support to that side of the business, in 2005 Haun Specialty Gases was formed. Haun Specialty Gases, a sister company to Haun Welding Supply, owns and operates a specialized, high efficiency gas fill plant which supplies high pressure industrial and medical gases as well as high purity specialty gases. The gases are distributed in both liquid form and high-pressure gas through more than 100,000 cylinders and dewars in the Haun system. Haun Specialty Gases manufactures most of the specialty gases it sells, enabling it to meet critical delivery requirements of both Haun Welding Supply and its direct customers. Today we are continuing the tradition of quality customer service that began with our founder, Orval Haun. Haun Welding Supply is committed to providing customers with innovative solutions to the myriad of technical problems faced by manufacturers, fabricators, maintenance personnel, and the individuals who are the foundation of the welding and industrial industries.
