About TIG welding and inverter conversion to TIG

[Zkemp]

Since your inverter seems to be ac , you cannot use it to weld steel effectively.
Also, I have heard someone on this thread say that you cannot use brazing filler rod with the tig process, and that's just incorrect. TIG brazing is a widely accepted process, it just requires more/different skill than Tig welding.
In America (not sure if it's the same elsewhere or not), we use ER70S-2 filler almost religiously, haha. But a great, slightly cheaper alternative is is RG45( or whatevery you would use gas welding steel) and that's what I learned learned on.
