All Gas & Welding Supply Company was founded in 1982 by the Taylor family after purchasing two small retail welding supply/gas distributors in the area. The parent company, Combined Energy Services, a full-service propane gas, heating oil, and engine fuels distributor, was started in 1968 and services the tri-state region of NY, PA, and NJ, with headquarters in Monticello, NY. Our micro-bulk CO2 beverage carbonation division, Tri-State Carbonation Service, was founded in 1985 and services parts of NY, NJ, PA, MA, VT, RI, and CT, including all of metro NYC and Long Island. Our commercial water treatment chemical supply and commercial swimming pool division, Wechsler Pool Supply Co., delivers liquid chlorine and water treatment chemicals to commercial pools and municipal water companies. As of 2021, we have six retail welding supply stores in the tri-state NY, NJ, PA region.
