I don't understand why he doesn't get sunburned either.  I'm sure the cigarettes will kill him first though. He must weld at least 4 hrs a day.  He always has some way cool project going on.  Last week was a 1916? Indian motorcycle exhaust (I love the indents in the gas tank above the unshielded spark plugs!), the top secret new Norton prototype, some old Ford with a flat head v-8 engine (only three in existence) and an order for half a dozen austin-healy exhaust headers.  He must like me because he tends to drop whatever and weld my stuff up for me while I wait.
    After Tom starts an arc his machine goes pretty much silent.  The rod gets dipped into the puddle on a cyclical basis.  He welds maybe an 1 1/2" length bead before he needs to turn the project.  He doesn't appear to be suntanned.  Safety practices could be better in his shop (like wearing goggles with grinders).  He paints some black stuff on the interior of the pipes for stainless and if the gaps to fill are too big he pressurizes the pipes with argon to prevent blobs inside that would catch heat and burn through.
    Cutting those pipes to intersect is an art.  you remove a 1/16th and suddenly it's a 1/4".  The pipe touches in one spot, you grind it down a bit and everything changes.  Working in three axis is challenging.

Was this TIG welded?  How does he keep his hand from getting that arc induced sunburn?  Man, I played with my TIG welder for about 15 minutes when I first got it.  I read all the warnings and such, and figured they only applied to people who did this hours a day.
