Tig Welding

Is Argon Gas for TIG Welding expensive?

I found this TIG Welder:

And I’m thinking about purchasing it to practice and do small projects. I was wondering if anyone knows how much Argon gas costs for these things, and how long it lasts?

Thank you.

Argon gas is not expensive at all. Buying the tank for argon gas is quite pricey. Once you have spent the money to purchase the tank refilling is cheap. You might be able to find used tanks at a flea market and have that filled. In fact you might be able to find some of mine stolen off of job sites. If purchasing a used tank you may also have to pay to have the tank tested. They require testing every 5 years and have a stamp near the neck to tell you when the last time it was tested.
Good luck with your TIG welding, it takes a lot of practice.
