    They look really good. Nicely fused runs.

    Going to do another vertical up but this time with single pulse as it is what I have been using most with the 1.2mm wire.
    Will then gather together some thinner stuff and see how things perform.

    It is interesting to see as I have never etched much Mig stuff.
    Notice some porosity although I notice the single pulse and the last vertical Up don't seem to have any, maybe cut at the right place :D

    Edit, scrap that comment, single pulse one also has a bubble :D

    Porosity is normal and to be expected.
    The cross-section area of the porosity is realitively proportional to the loss in strength, so one little bubble is really nothing to be worried about.

    Try cutting a normal non pulsed mig weld, in theory there should be a lot more porosity, particularly at lower amps.

    The interesting thing is, if you look at the last pic, there seems to be a bubble in the base material itself. Maybe that is just an artefact of the way I cut it or something?

    Not really bothered about the small bubbles, once had real porosity issues and I had a heck of a job finding the problem, turned out to be a pinhole in the gas hose, must have been drawing in air as the Argon flowed.

    I think I have only done one etch of Alu that has been done with an ordinary mig and if I recall it was ok but again I probably just cut it at the right spot :D

    Wondering if maybe this should be moved to its own topic to save cluttering up your post @Brad93 ? Might also encourage others to post?

    Ok last one on 1/2", will move on to thinner stuff now.

    I've not done any vertical up with mine I will have to have a go at some point, think it still has a spool of Ali on it at the minute. Not had the time recently, koi have been giving me nightmare

    Haven't had the handy tig on AC for well over a month. Just sat down, whacked a #5 on and this is the result.

    It's all the machine mate. I've run a lot of machines, this little HT200 holds its own against the big boys. I've used synchrowaves, aerowaves, dynasty's, Esabs, a Lincoln, and Richards old Kemppi, this combines simplicity with some stunning arc characteristics, which some of the others really struggle with.

    No worries. There's a few hidden ones that make a big difference when getting down to the thin stuff on AC.

    Cheers Brad, question, when you are using the pedal.......the on torch control switch is this still needed to be connected to the front panel ?.

    Yeah the pedal plugs in the back the torch in the front. You have to have a torch switch connected on the lorch if you have intelligent control enabled. You can turn it off but I haven't got round to it. Intelligent control is the ability to control amperage and program from the power master torches

    Cheers, just looking to use a plain CK9 and 17 on mine to keep the torch size down for now, and control amps via pedal.
    Only use the torch it comes with on heavier stuff if I have too.

    Pics above out of 3mm Alu ?.

    Yep 3mm full pen but not too much burn through.
    If you get a lorch, send me a private message I'll sort you out with some settings
