I am a first time TIG wannabe. I needed some aluminum welding done on my boat, long story short, I could not get anyone to come to my house (boat is in the water). I decided to buy my own welder, I researched, checked out the cheaper china brands and ended up with a Miller Dynasty 200 SD with a finger tip control contractor kit. I have only been able to read a lot but I have no one to show me right from wrong, and I can sure melt some aluminum. First, how can I tell if the HF is working? It seems that the only way to get an arc is if I touch start it. I have been playing with 1/8" pieces of aluminum, I have the machine set to the specs in the manual and from Millers welding calculater. I have been using 3/32 red band tungston sharpened to a point (thats what the miller store told me to use). It seems that maybe its way to hot, do I get it hot at first and then turn it down when a puddle forms? What would a good learning project be, trying to stick two pieces together or just try to run a normal looking bead on a piece of flat stock? Any help will be a big help. Are there any good videos or DVD's that will show me some pointers? Thanks
