I've got a moderately old Lincoln Weld-Pak 100. I'm going to be teaching
a friend of mine how to weld with it. However her projects involve
stainless rather than mild steel. I picked up some .023 stainless wire at
at 75% discount (whoo-hoo for heading in at inventory time).
The main question is, will the finished project need to be passivated?
Secondarily, is there anything I should pay attention for when welding
stainless if I've never done it before? The Weld-Pak does have the gas
attachment, and I'm running 25/75 gas.

Short stickout on your wire, because ss is a poor conductor. Bevel and
preheat thicker pieces (1/4" and greater). Better results with tri-mix
gas, but a small project probably wouldn't justify the cost. Use the heat
tint removal paste if you need to get rid of the rainbow.
Whatcha building?

Crowns/coronets. Similar to the ones lower down on this page:
http://www.signetring.com/Coronet/coronet.htm
Probably won't get much over 16 ga thick. I'm not sure of the alloy, but
I don't think it is 400 series, probably 300 series. My wire is 308L.
And yeah, it probably won't be worth getting tri-mix unless my friend
winds up getting a lot of business (not the site listed...I have no
connection with them). If it is, I've got an account at the local Airgas,
so no problems finding it.
Thanks for the tips!

You should be fine with that setup, just keep it tight. I haven't been to a
RenFest in quite some time. I bet the boy would dig it.
Good luck!

Passivation? Why would you think you need it passivated? Unless you are
cutting or abrading it with carbon steel and you are then very concerned
about minor rust spots you need not worry.
