    regal,

    Understand that I'm not "picking on you" but sounds like you're trying to "think" yourself right out of being a proficient tig welder.

    You're not alone in this, which is unfortunate. We guys, who've been around for awhile, just sit back and shake our heads at some of the "newbie" questions that are asked on a message board. So many of our new welders think they have to have all the "latest bells and whistles" to be proficient at tig welding. Often times, these are the guys who go out and buy the Chinese crap because it offers those b&w's and they're not willing to buy quality.

    That is not the case with you and the Dynasty 350. That is truly a top of the line, advanced tig welder, however, there is a reason why some of the more advanced features are called "advanced features".

    I don't care how advanced the machine is, it still comes down to seat time and understanding the basics of tig welding. Andy's explanation earlier in this post is as good as any you're going to find. You may also do a search on postings by KB Fabrications. Kevin has probably "gone further" with exploring the "advanced features" of the Dynasty 350 than any other poster I've seen on the board. He doesn't post much anymore because he got tired of the repetetive bs questions from people who don't put forth any effort to do their own research.

    The independent amplitude/amperage control of the Dynasty 350 is truly an "advanced feature". You're not going to find any "cookie cutter" solutions as to settings, etc because every case is different. An advanced tigger will understand that and will experiment with his machine to achieve the optimum result. Those settings will be "just right" for him, but may not work for the next guy because of difference in technique, etc.

    I've followed your progression with tig on the board and, quite frankly, you're not at a point where you should be loosing sleep about certain capabilities that you don't understand at this point. Moving from a transformer to an inverter with the greater range of balance control and the ability to change the frequency will give you plenty to think about for the foreseeable future. When you get to the point that those features are not giving you that "perfect result", that will be the time to worry about individual amplitude. You're not there yet. Focus on the basics. Play with the "advanced features" if you wish to see what they do FOR YOU, but don't let them get in the way of your development.

    Just because you have a 600 HP Corvette that will run 150 MPH doesn't mean you have do drive it down the highway at that speed. Best learn how to get it thru the curves before you "open it up".

    Advanced tiggers will learn how to make advanced features work for them.

    I have a Kemppi tig welder which has a Mix Tig function which pulses the machine between AC and Dc for Aluminium welding.
    The machine uses the ac function to clean and the dc to heat.You can use a
    sharpened thoriated tungsten and it keeps a very focussed arc
