My first post. (I dont speak english so please excuse my mistakes)
I'm so happy reading this post, tanked is what I have beacause my main work is jewelry and where I live tanks and oxigen are cheap, also they deliver them to my home!
I was thinking on buying a concentrator for my new bobcat (coming soon), but now I'll wait and see!
Thank you so much for sharing your experiences and knwoledge!!! great forum!!!
