It is very caustic and you must not breathe the fumes. I need to get an insert for my respirator rated for it.
Hard to hold my breath and solder
The solder I have, the flux I don't. I was going to buy the Harris solder and flux for stainless for my diffuser. I didn't want to spend another 65 dollars on the solder and I never asked about the flux. So I welded it instead.
That's the white or the black flux you used?
