Once I had the idea in my head I used the advice from the How to Make a $1,000 a Month Business course and validated it by seeing if anyone would be willing to buy my product before I invested any time or money into it.
Interesting facts Argon is created when the potassium in the earth's crust decays. It's the most abundant of rare gases. It emits light when electronically excited. About .94% of the earth's atmosphere contains argon.
You can use argon as a shielding gas for either MIG or TIG welding. Argon is merely the gas used in the process. When using stainless wire in a MIG welding process you can use 100% argon gas. TIG welding of aluminum uses 100% argon also.
