    Paul,
    As a senior member and having a few years in the trade you should be aware of the dangers of having a o2 tank inside the shop whitout being purged. Welding should never be done while product is still in the tank, you are setting a bad example for all the young guns out there, we should be teaching them how to be safe in the workplace.

    Doug.

    Remember if weld is black or dark gray in color like oxidized then there is a few things to keep in mind. One /amps used want you want use as little as possible ,stainless does dissipate heat well so easy to over heat. Stainless has a lower melting point then that of steel. Gas flow 17 to 20cfh. Electrode to work distance is also important with stainless the closer the better 1/16 of and inch, to long increases arc volts. Then you want the biggest sheilding cup you can like a 10. That gives you better gas coverage so atmostphere doesnt hit the bead when it is hot. that is the most common that causes the color of the bead.

    good luck

    It's actually the opposite. SS does not dissipate heat very well (in comparison to mild steel, aluminum etc...). It's easy to overheat because the heat stays in such a small area and doesn't dissipate from the weld zone.

    Default Love to see this stuff

    I'm new to welding and this is exactly the kind of stuff I like to see. I've had no formal training so seeing what the big guns do gives me a point to aim for. Thanks Guys
