here, i couldn't test it myself for some reason
i was hoping to see if anyone tested it out before, at least i learnt from others experience, if not from the exact test
about the spot weld you mentioned, i suppose those are without any shielding gas, isn't it ?

I watched the Jody video regarding speed tacking with a blast of amps for thin metals, and was curios about how much argon gas is really working and affecting during that fraction of a second. Originally the question without Argon gas was only for "Tacking" and not for a complete continuou...

Glad to receive good advices. Please correct me if I am wrong, in other words, the argon gas not only serves to shield the weld puddle, but also it serves to protect the tungsten? Then wouldn't it make the pre-flow a MUST for all welders? I am worried for the model i have, not sure if it has pre-flo...

Thanks much for the prompt reply. Would it be possible to request Jody or his team to make a short video doing it with Argon and without Argon to compare the difference? It would be really educational/experimental for newbie to see the result of how much effect can Argon make even for just a fractio...

Hi
Just a quick question, I wonder would it be even slightly possible that i tack weld some thin stainless steel with TIG WITHOUT argon gas?
Thanks in advance for any advice
