I just purchased an HTP221 and so far I am very impressed and a little overwhelmed. This machine allows for a lot of adjustability, but for my ability right now I find all those adjustments overwhelming.  I'm playing with steel right now and find the pulse feature to be really helpful on sheet metal, but not sure if I'm setting up the machine in the optimum way. I plan on practicing a lot to learn what works best, but I could really use some help ahead of time. Do you wise folks recommend a "bible" of sorts, something that shows what optional settings for these new TIG inverter machines work best on different materials / thicknesses?  Maybe something in the form of a "matrix" that shows the material on the left and the different options across the top, especially for aluminum (AC settings come into play).  any help appreciated!
Reply:This helped me intensly early on. I know it is Dynasty related, but many aspects are generic to all inverter tigs. You have the Euro style panel on your machine. Anyway have a look. Lot's of pages and info.http://www.millerwelds.com/resources...ocesses-Set-UpWeld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
Reply:it should have but it didn't occur to me that Miller might have a more elaborate owners manual or other materials for the dynasty 200 that might help, I'll check that out.  Thanks!
Reply:Here's what I've learned so far after some practice and searchingMiller has some good info, not so much their dynasty manual, but their general references show some good info. The HTP manual is also helpful so it pays to read it and have it handy. I've done some 20-ish gauge mild steel straight and with pulse, and I can say that a higher frequency pulse works very well to control heat input and burn-through.  Especially when using an oversize tungston.  without pulse I have a hard time getting enough heat in to move quickly (to reduce overall heat input) without burning through.  I did some 1/8" aluminum last night and found that 200HZ frequency with 60% (high) AC balance produced a great balance of cleaning and tungston life.  I used 2% lanthaniated 3/32 sharpened to a point with great success.  I tried 40% balance on 1/16 tungston and it quickly burned it up into a ball.  I can't imagine using 40% or less on any type of aluminum with a thin tungston, if you want more cleaning and want to use this setting you need to up-size IMO, I was just welding raw angle from home depot and 60% still gave all the cleaning I needed without any prep... granted it was practice and not structural. I'm working on my own "cheat sheet" for settings as I gain experience and will try to post it here.
Reply:Here is a chart that Conrad Andres (Weld Talk Forum member from way back) made based off the Miller charts that are in the Tig Guide- it was a free download at one time but now you have to order the book $29.00He made this when the TA185 hit the scene.Topic 7.
