Welding Gases

Here are a few considerations for choosing shielding gas that will help keep your arc stable:

  • Machine capabilities: Do both your gas and machine support the modes of transfer you plan to complete?
  • Cylinder size: Do you know your cylinder’s approximate size and CGA connection?
  • Base Metal: Are you using the right gas for the material you’re welding?
