To make successful aluminum welds you must set your TIG machine to A/C, so make sure you get a tungsten rod meant for running alternating current. If it is pure tungsten (green band on the end), you're good. For the tip, just grind a tip like you normally would. When you start welding a bit of aluminum will collect on your electrode. After that you may need to break off the tip every now and then if you get a lot of junk in the ball. Make sure you practice on some scrap first, aluminum is very different to run than other metals. Getting the right operating temperature down is a bit trickier too.
Just in case you're working on something serious like a motorcycle frame, make sure the aluminum you're using is a grade that's able to be welded. I've heard about a guy that built costom bikes and used the wrong grade, when the customer took the bike down the highway it fell apart on him.

What gas are you running ?
Aluminium needs Argon mix - try increasing gas rate to provide sufficient shielding - and work indoors.
If this doesn't solve it -
Try using a lower amperage as I think you may be overheating. Alternatively - use a different make of tungsten.
Don't dip electrode, as this will eat it up.

I think you mean you have a Miller Synchrowave 200.
Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.
Now - these are just generic settings, but they will get you going.
