There was a time (the 20th Century) when industrial gas meant simply oxygen and acetylene for welding. Now we have Argon CO2 mixes for short arc welding or MIG welding, Argon O2 mixes for spray arc welding, Argon Helium for mechanized welding, and Argon Hydrogen. We carry a wide selection of industrial gases and mixes to fit the needs of our customers. From scuba divers to welders to medical professionals, Eureka Oxygen has the gas you need.

There are many modes of welding – and Eureka Oxygen handles them all, including the leading brands in welding. We have all kinds of welding supplies available. Eureka Oxygen is also an authorized repair facility for Miller Welders. We also have Victor, Smith, and Uniweld cutting torches.
