    The Lincoln Aspect 300 has independent amps EN and EP, they did something funny to get around the patent I think. I've had a bit of a play with the Aspect at work but it's not my machine so i can't really spend the time finding out its capabilities.

    Zank's settings - for anyone who doesn't want to google:

    Basically if you don't have a Dynasty/Aspect of the right spec, you can't do what Zank was doing.
    Thanks for the link, been looking for that but no googlefu skills here. There was another thread by him or another that went a little more in depth.

    Anyhow, I have ordered the sd card for my 280...

    I am thinking that for anodized I will want the EP section of the wave on advanced square because my understanding of bump welding leads me to believe that the extreme cleaning comes from the instantaneous HF high amp burst caused by the finger switch. This high ep burst when coupled with the ac pulse feature may allow for something similar to bump welding. The en side could then be triangle and lower amps to possibly be a little more forgiving on the relatively thin wall tubing I find myself doing. Either way it will be fun to experiment and I have the extra cash right now.

It's basically in a class of it's own. 220A, loaded AC TIG features, cheaper than a Miller, all while being just as stout if not more. Oh and it's been out since 2011.
    If they had a ~300 amp machine when I bought the Miller I may have gone that way...but while they have the independant amplitude they lack the ac pulse and wave shape, correct me if I am mistaken. The better half worked for a company bought by ITW and I have no, none, absolutely zero respect for that corporation!!! At the time of purchase I didnt know they owned Miller or I would have bought the lincoln. I find it enlightening that none of the products they sell have any visible "proud to be an ITW company sticker " or anything on them. They seem to own a lot of once great brands...paslode, Miller, Hobart, etc...

    It has "a little" AC pulse, lol. Up to 10Hz, and correct on the lack-of wave-shape. The new one will probably have wave-shape though. Time will tell.

    ah, ok, I beg apologies! The thing is, absolutely no-one has heard of a HTP where i am, nor any Stel dealers anywhere near here, and of course dealers are only going to know what they have to know about the models they come up against.

    Been searching about a bit more on this subject of independent EP/EN, here's Zank and Dave's comments on a thread found on here:
