View Full Version : C25 or Argon
05-24-2011, 01:36 PM
I know for TIG I should use 100% argon, but could I temporary use C25 instead? I have this almost full bottle of C25 and I hate to not use it. Thanks in advance for any help.

I`ve only used staight argon or helium or a mix of the 2. Any other gasses in the mix I would think would cause porosity in the weld zone.

In a word the answer is.....NO, CO2 will react and mess up your material as well as your consumables and possibly your equipment. Sorry.
