Hey gents. Just thought I'd say Hi and introduce myself in here. Been a welder for over 10 years now professionally, fully certifed for 6; its been fun.

One addition to the direction of the conversation: when you change shielding gasses say, from straight CO2 to Argon, your machine settings will need to be changed also due to the gas having a slightly different ionization characteristics. For example, argon gas gives you a narrower weld with greater penetration, the Oxygen in CO2 gives you a "hotter" arc, Helium gives IMMENSE penetration and "wets" out your puddle. This is why there is no universal shielding gas.

Just my .02 of brain food for now.
