Can you Tig Weld without Gas

Simply put, NO, you can’t Tig weld without Gas!

Gas is required to protect both the Tungsten Electrode and the weld pool from Oxygen. Most Tig Welder torches are also cooled by the gas, so not using gas would risk burning out the Torch.

It’s theoretically possible to use a Flux, in the same way as Gas Brazing, but this would leave the Tungsten Electrode unprotected from Oxygen, so it would go black and burn away REALLY quickly. Plus, as previously mentioned, you risk overheating a gas cooled torch.

So sorry, but you need Gas to Tig Weld properly!

For most Tig Welding Applications, Pure Argon Gas is ideal, although more exotic (and expensive), gases are available for specific applications.
