    Default Need help in selecting TIG system

    Hello:

    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.

    you might consider some thing like a propain or mapp gas and oxygen setup. much smaller and easyer to deal with than a true O/A setup.
    also aladden makes some brasing rod for aluminum that will work with this system..i'll see if i can find you a link to them.
    the SD-DX diference is going to increse the resail of the dyn if that is of a concern. the DX will also alow for pulse wich makes some really nice designs on SS. some thing you might want to consider. not shore if the pulse will be worth the added expense to ya in your work as i'm not real shore your use, but to TIG its verry helpfull in thin matereal and SS so i would defenetly consider it.
    as for brazing with TIG ?? never tryed it, always used O/A sorry.i just dont see the TIG arc as being the idea brazing heat scorce.

    welcome to the site, some one with a lil more TIG expereance might jump in and help out with the brazing option.
    thanks for the help
    ......or..........
    hope i helped

    feel free to shoot me an e-mail direct i have time to chat. james@newyorkmetalart.com
    summer is here, plant a tree. if you don't have space or time to plant one sponsor some one else to plant one for you. a tree is an investment in our planet, help it out.

    You will still need a tank of Argon for a TiG machine, no matter what you do with it, brazing, welding, frying ants.... The gas protects the electrode (tungsten) from burning up.

    i think his concern is large flamible tanks. but true you will need argon tank.
