From the business
In the shop's own words: “About United Welding Supply Co”
United Welding Supply Co is a welding and gas supply shop in the heart of Los Angeles, where customers walk in with an empty CO2 or oxygen tank and walk out with a full one, usually in under half an hour.
We work with home brewers, aquarium and hydroponics growers, and welders and jewelers who need a reliable place to refill or swap a tank. Every tank we hand over passes hydrostatic testing, so it is safe and up to date before it leaves our counter.
Wayne and the team take the time to explain how your setup works, whether that means walking a first time torch user through assembly or making sure a kegerator owner leaves with the right size tank for their setup.
- Same-visit CO2 and oxygen refills
- Hydrostatic testing on every tank
- Serves brewers, growers, and welders
- Patient, hands-on help for first-timers
