Don't, you'll be dissappointed and frustrated. Tack it and take it to be tigged. Or even migged.I have some 1.5mm SS exhaust pipe to weld with my arc welder. Is it possible with 1.6mm or even 2.0mm rods. I only have Arc, my DC inverter goes down to 10amps. Im fortunate to have a v good fit up.
And make sure whoever does it, back purges it too (if you want a proper job doing!)Don't, you'll be dissappointed and frustrated. Tack it and take it to be tigged. Or even migged.
But @Hood , you are a more than competent welder, with knowledge, experience and the right kit. Not to mention your test piece is nice and flat on the bench, not disappearing out of site round the corner.Just done a test, don't have tube so used some 1.5mm plate

suspended in free air to simulate no backing as you would have on tube.

30amps 1.6mm electrode, probably should have been 35Amps though.

Not happening with a buzzbox, needs a nice smooth arc, even a lot of inverter welders are not that great for low current and 1.6 stainless rods.I tried on a buzzbox some time ago, made loads of blobs...
in a few years they wont be able to see enough to worry ,, all will be grand .I've seen the 'muffler men' in the Philippines welding stainless silencers up with a stick welder, they do a series of tacks, hot on hot, and make a surprisingly good job of it. And all done wearing sunglasses too....
Thing is, very few of them can actually put a proper weld run down anyway.
