RE:RE:RE:RE:Melting GoldGogotv......Toxic Gas?? Ok, I'll confront YOU with the subject of toxic gas. Can you be more specific on what type of gas the torch emits that is toxic?? I'm gonna assume it's NOx gas. NOx gas is produced from a reaction of oxygen and nitrogen which is naturally occurring in atmospheric air. NOx gas is produced from HIGH FURNACE TEMPERATURES, NOT the plasma torch. If you have any experience in industry you would know that all high temp processes produce NOx gas. And another interesting fact is that burning fuels such as natural gas produces huge amounts of NOx. The plasma torch is an extremely green alternative. You are misinformed and very uneducated... good try gogotv..
