Passivating in quantity is a bit of a pain and yes the cost of the machine sucks. Its way faster using a "real" machine with some decent amperage behind it I agree. Then its all to neutralise afterwards, or you get left with acid salts that eventually corrode. Acid is around £100/gallon, so is most neutraliser, although I'm using one that dilutes 1:10 which softens the cost a bit. I have to price passivating pretty high, because neither me or my brother fancy doing it for labourer wages.Haha i'm not setup for stainless really, to do any quantity you'd have to buy an electro passivating machine and i just don't do that much.
I don't enjoy dealing with the distortion anyhow, although it is fun to weld and aim to get better with each one.
I have a customer that wants 300m of 6-8" half round stainless gutter
300m of gutters, wow. Could do them in 2m lengths that would make it a bit more palatable. Would have to be 1.6mm minimum in my opinion, or would have to have a proper purge block on the bottom side to prevent burn through.
Bump bending a full half round would be ok with the right tooling, but not something I have.















It was more solid a couple meters down, it also pee'd out about 10 gallons of dark wee coloured liquid as I cut into it. My ropes may need a wash.
