    Correct on the polarity if he's welding steel, completely wrong on the gas flow no matter what he's welding.

    Perhaps we should not be so quick to judge on the gas flow, since we really have no info on what type of regulator is in use. Maybe... his regulator only puts out 15 cfh.

    Bad advice is bad advice....40 CFH Argon..?? that was just plain wrong...

    we do a great disservice to the beginner when we let that type of misinformation slide...

    I too have recently begun tig welding. I scoured the web for a lot of resources and half of the time forget to bookmark those pages. I came across a kickbutt mobile app that basically has everything in it devoted to tig welding. The app name is iTig and I believe it only works on the ipad/iphone.

    Hope this helps!

    Hey Ron, lot of good advice here. I'll add this. I downloaded the app for iphone iTig. Helped me out a lot. Comes with a calculator. Just select your material, thickness and joint type and it tells you what to set your machine at. Get's you really close. Has a lot more too but that's what I mainly use it for.

    Hope this helps you out some.

    Default Beginning TIG welder...need some guidance.

    As a firefighter/gtaw welder, when you use high levels (over 20cfh) you are simply creating whats called a "venturi" effect. Ie: a force through confined space (cup), creating suction, introducing (O2).

    Your cfh is so rapid that it causes a sucking effect from static/ambient O2 source into ur welds due to vacum/ venturi effect.

    Also keep in mind what it is your welding. I do heat exchangers for a living. Tight pipe saddle joints which will only intensify turbulence. Think of it as concentrated air movement between sky scrapers. Believe its called "Stack Effect". My uneducated peers (absolute fools), think its best to jack up amps, wack out the CFH, to get it done. Their welds look like burnt, smeared, dog poop, to be honest! Go back to school!!

    Trueth is, 20cfh, and 1 amp per thousandth base material, and torch angle is all it takes, return to basics.

    Argons air density is much heavier then ambient air, there for it will only descend. Treat it as such, in a calm manner and hold shielding coverage. I work with titanium and zirconium, even though I weld in sterile white gloves, I never exceed 20cfh. I simply extent the post flow rate, 5-15 seconds longer.

    The name "argon" is derived from the Greek word αργον, neuter singular form of αργος meaning "lazy" or "inactive", as a reference to the fact that the element undergoes almost no chemical react
