I am looking into doing some metal artwork and jewelry, using recycled metal object, mainly bicycle parts.

I will most likely be working with mild & stainless steel, aluminum, and perhaps brass. The metals that I work with are most likely to be 3/16th inch or thinner, most likely not much more than 1/16th inch thick.

This would require me to have a TIG set up, so I am looking at both the
Maxtar 200 and Dynasty 200 series.

One thing that I would like to be able to do is to do brazing using a TIG set up. I was told that this is possible provided I use the correct fill and that I can set the TIG unit to a low enough current so not to melt the base metals that I am joining, but melt only the filler.

I would like to be able to to brazing with the TIG system because I don't want to have to have any system using gasses. I don't want the hassle and dangers associated with tanks and I plan to do the work in a converted room in my apartment and I figure that my landlord would go ape if he knew that I had tanks.
The only way that I would be willing to use gas would be to have a water torch, but I am told these are too small for working with metals up to 3/16th thick.

Perhaps if any of you have had any experience with water torches (which generate hydrogen and oxygen by electrolysis of water); you can give me some help.

I am also hoping to do brazing because I want the flexibility to join dissimilar metals that I can't do with welding.

The joints that I make are for artistic use. I do not plan to use anything for structural use that would requiere passing an inspection.

I hear that welding aluminum requires and AC arc. Does anyone know if I can braze aluminum with DC?

I am also curious between the difference between the Dynasty 200 SD and 200 DX and whether or not the added cost of the 200 DX is worth it for my type of work.

Thank you for your help.
