Standing by your original reversed statements that do not agree with any tungsten manufacturer that I've seen, nor any welding instruction I've seen or experienced, is a bold stance. ;) My point: Blunt grind = deeper penetration, handles more amps Long narrow grind = wider arc cone, less...

"Regardless of what the chart says" isn't a very good way to approach a disagreement on the technical side of welding - in my humble opinion. The spot on plate test clearly shows what it shows. The same results hold if it's a straight weld - using argon of course. Other gases can yield...

Yep, sharp tip for for lower penetration and excellent low amp arc stability. :)

Hey Gary, here is some information you may wish to review. I also tig Gary, but I have fewer years in than you do. :)

I would respectfully disagree Gary. You have those reversed. Electricity exits a surface at 90 degrees. As a result, the more of a needle point you have, the wider the arc and the shallower the penetration. A nice sharp tip does give more stable low amperage starts though. A blunter grind...

Nicely done! :) Excellent attention to detail.

Never practice on the part. Practice on scrap. The headache saved is huge. Even if it takes an hour to practice up for one weld, it's better than spending that hour trying to fix the messed up part.
