Greetings all,

First the gloat, salesman come into the shop last week with a BIG box,
nice shiny new Dynasty 700 contained within. Fully loaded, TigRunner slung
underneath, 2 torches, all the bell, whistles, knobs, buttons and dancing
women you could ever want. OK, so I'm lying about the dancing women, but
who needs them when you can weld Alum with a beautiful inverter based rig
like this??
The boss was only contemplating purchasing it, but once he and the Shop
Foreman used it I think it pretty much sealed the deal, I hope so anyway.

Now for the question, please bear with me. Is it possible to clean SS
parts(1 1/4x1 1/4x3/16 Angle Iron) of the welding brownies using a
de-browning(?) agent, either an acid or Citrasafe(sp), in a process similar
to anodizing in that we could build a tank, submerge the parts and pass a
small current threw it the solution to speed the process along?

Do-ability, Dangers, replies that I am an idiot, all welcome and
appreciated.

Thanks in advance,
Jim

Are you talking about simple oxidation colors or are you talking about
crusty black "sugaring" (looks like burnt sugar)?

The oxidation colors are easy to chemically remove using Citrisurf and
electricity.

Sugaring must be mechanically removed, and then passivated.

Yes Ernie, teh discoloration from welding, both GMAW and GTAW.

That's what I had hoped to hear, realizing this is probably a loaded
question, any idea what size tank a standard battery charger would be able
to handle? Or would we need to go more industrial sized, possibly even
ultra sonic? The parts are approx. 5'x5'x1 1/2", (frames built out of 1
1/2" angle), ideally I think we would be doing more than 1 at a time since
there are well over 1,300 pcs. involved here.

Sugaring must be mechanically removed, and then passivated.

Pardon my ignorance, but could someone give the definition of passivation?
I have seen/heard it for a while now, would appreciate a definition.
