SOURCE: How to TIG Weld
TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and Heliarc® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.

Wow you have a lot of variables here. Let's go over some of them.1.AC current 2.100%argon shield gas 3.Check your Tungsten, it must be the recommended 1or 2% and the right size, clean and the tip rounded by meting 4. High freq. turned to continous-not just "START"
5. CLEAN,CLEAN,CLEAN your Alum. with a S.S. brush that has touched NOTHING else in in it's life!
Start here and GOOD luck

Hello; Make sure AC Auto Balancing is Enabled; And when Welding Aluminum Aways use 100% Pure Green Coded Tugsten.Make Sure you dont have 75/25 or possibly if you know for sure your frequency balancing on your machine is working you could possibly have a bad bottle of gas try the bottle of gas on the machine that you say that runs good if it runs good put it back on the 225 if the problems still exist there is something wrong with your machine`s Ac high freqency Auto Balancing.Make sure all connections are good,check tig head for loose connections. Step Up to A 1/8 size tugsten it will carry more heat and gets less contanimated.Every time you stick your tugsten it will run contanimated untill you burn it off or clean it ,if you stick you tugsten go ahead and put a clean piece back in the tig head, Contanimated tugsten wil run dirty for 5 to 20 minutes Untill you BURN it Back Clean !?
