Re: What kind of oxygen tank and cylinder do I buy???is welding oxygen safe??

i can't answer about the technical aspect of the machinery. however, why do you have mold issues? is it from your environment/living situation? if so, then i would suggest flooding your house/apt with ozone. close your doors and windows, set your machine on high, and leave the house for a good 8 hours or more. just blast it. when you get back be sure to air it out VERY thoroughly before breathing the air.
