Welding or Brazing

You might be wondering what type of technique is best, cheaper, or preferred. We gathered some resources on this section to help you choose your setup

Popular methods for “gluing” steel tubes are TIG welding, brazing with Oxy-Acetylene, and brazing with oxygen concentrator-propane.

  • acetylene vs propane
  • If you’re going to use a TIG welder check out this video from Cobra Framebuilding explaining the setup needed.
  • If you’re just starting and want to go with the cheapest option then the Oxygen concentrator/ propane is the right option.
Oxy Concentrator and propane beginner setup:
  1. Torch handle – Some popular torches are Uniweld 71, Victor J-28, and Smith AW1A
  2. Tips – The site http://www.paigetools.com/ sells torches and tips specific for Propane / Oxy setups.
  3. Propane regulator – Example
  4. New or used O2 concentrator- Any Oxygen concentrator with 5 LMP should be enough. You can find them online on pages like dotmed.com or at Ebay.com
  5. AB fitting hose set – Like this one.
  6. Propane tank – The one you use for your barbecue. 🙂
