Punsfluckett, Throttlebottom, Snead and Purvey have advised me to disavow any
recommendation of welding techniques not approved by OSHA, whoever they are.
I did want to note that I am very leary of eye exposure in welding.
Someone here spoke of using a '9' lens for .023 wire, which does make it
easier, but I'd still never go less than '10'. My helmet is modified with
leather duct taped to the bottom and side edges so that I CAN safely look away
(I still close my eyes) without closing the visor, but still only for little
tap bursts.
I was tempted by the automatic lenses, but, the 'window' of vulnerability
before they shade is (if I remember correctly) 1/100th of a sec. That means
in essence that for every 100 welds (not a lot with a rusty or wrecked car)
you've looked directly into the arc unshielded for a full second. Not good.
And that's if you believe it's really 1/100th of a second.
I don't understand, with all the wireless technology around, why someone
hasn't produced something that would key off the trigger and shade 1/100th
BEFORE the arc started. Now that I'd buy.

it's very fast. I don't even bother putting the visor down for the blobs
part, just look away each time since the gun is braced on the metal, and I
usually stop briefly after completing the blob ring to let things cool,
just
to be antiwarp safe. But after a little practice (very little, this really
is
a fast learning curve), if you don't bother to wait, you can do a hole
start
to finish in 20-30 sec. !! And it will look good and be clean solid and
almost flat metal. >>
Wow, I really appreciate both Chris and Tim sharing their experience. In
welding stuff on my Tiger and various ther projects, fixing holes was
defintiely a needed skill. In addition I would add I sometimes cut little
circular disks of scrap metal and welded them in to serve as backing for the
holes. Chris' tip about not using the mask was interesting.
