I bought the flux from Tinman a while back...It's just been sitting, waiting for me to invest in a gas welding setup. The manufacturer of that unit in your link sells directly...in fact, they sell factory refurbs for around a grand.

Would a unit like this be a smart idea, in lieu of a traditional O/A setup? Do the little nozzles on the torch produce enough "umph" to do the job? It appears at though there's a flux that is produced in the chemical process of converting to hydrogen....would I still use the flux I got from Kent? Now that summer is winding down, I'll have more time to spend in my garage with my metal shaping activities.

I went out and did a little test with the hydro welder we have. I could not get a 14 gauge tip to keep a flame. The image attached is an 18 gauge tip. Standard hypodermic tips. Plastic ones like the image don't last long. All stainless are available. I didn't have flux here to weld, but I could melt .040 Alum.
