Welding Stainless Steel

[4440]

Looking for a small quantity of Pickling PSt for the very small amount of stainless steel welding I do.
Any suggestions?
Thanks.

Ebay? https://www.ebay.co.uk/itm/193728990448?epid=22005154564&hash=item2d1b25ccf0:g:SPIAAOSwj1RfFq1b
Not too dear, and keeps a long while without going off. Might last you a lifetime of welding (if you are nearly as old as me)

Thanks, I was hoping for a little less than 2kg. I would think it would out live me.

Last time I needed some (years ago), I arrived at my local stainless steel fabrication workshop at 5:00 on a Friday afternoon with a small box of his favourite cold alcoholic beverages in one hand and an empty plastic jar in the other hand.

I dont really want to use it, but I dont think there is anything better to use.

What are you doing that requires pickling - dairy? Otherwise in general we just brush the weldburn off with wire brushes or scotchbrite poly discs.

We tend to use a phosphoric acid solution and an electro-passivator these days, it's far safer and faster than pickling paste. You can make a passivator machine for under £50, although the "proper" ones are ruinously expensive.

Passivater/tig brush/electrolyte cleaner

So I've been thinking about purchasing a passivater (maybe it's spelled passivator) but of course the cost of such a machine is putting me off. Some of the work I do is a bit too fine to be cleaned off with pickling paste these days (milky stains) Does anyone remember when these machines were...

I used my TIG set at min amps last time, but it wasn't a true 5 amp output as it was on lift-TIG, so it crackled and banged a bit too much. A 3-5 amp output at 12-15 volts would be ideal. Then you just need a holder for the carbon brush, and some phosphoric acid or other solution.
