    That would be the High Frequency start. BTW you don't want to do that much. It's meant to just be on for the fraction of a second it takes to start the arc. The instant that the real arc starts the HF cuts out. If you let the HF arc a lot you are just burning out an important part.

    HF start yes, on tig AC welding aluminum it's thru out the weld

    Actually on this machine I don't believe it runs HF continuous on AC. The switching time is so quick that it isn't needed. Only on older machines where the arc would go out crossing 0. Mostly transformer machines required countinous HF on AC.

    Yes I had Miller Goldstar 320 Transformer and would run when set. Maybe that's why it would turn the meter fast?? Lol

    I also thought it was the cleaning action around the actual fusion/molten area? You could see a sort of de-oxidation, maybe it was just the heat transfer?

    The cleaning action is a function of the EP part of the waveform. Not related to high frequency.

    Follow up to my AHP welder story... I got the knob board from AHP, installed it and the welder works just fine... Now I just have to melt some metal and learn how to TIG those nice beads...

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Hey,

    Thanks for including the outcome on the unit. AHP had an accurate diagnosois and elegant solution in sending you the part to get you going, even though the unit wasn't sold by an authorized dealer and could have even been a used one as far as they knew.

    Nice, AHP!!!!

    Just for the information of any who read this thread, AHP (AHPwelds), Amazon, SouthPaw (WW member), Kevin Caron (also WW member here), Weld.com (I believe may be authorized), and HomeDepot (undoubtedly is also) are about the only authorized AHP sellers that I know of.

    There may be others though, but I'd undoubtedly want to stay with the ones above, especially as some of them will incur no sales tax.

    sort of wonder why there has not been any mods to this tig unit...

    like bigger caps...etc...

    Well, mods start with a need. The needs so far have revolved around improving the peripherals (torch and pedal). Since many folks find even those to be acceptable, there is not much motive to hack it.

    An inverter welder is most likely designed as a system. Most modifications will reduce performance If it is well designed in the first place. Like my car... Designed for smooth acceleration, high mileage, high reliability and extremely low emissions. Any changes I make will likely reduce one or more of those positive attributes.

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Yeah,

    The AHP and most inverter welding units are not designed for max-amp arc-gouging.

    So, yeah, he broke it! And then he fixed it. And I suppose it's nice to see how to beef it up well.

    But arc-gouging is hard on even machines designed for it, voltage-wise, I believe, like engine-driven welders. So, it's kind of silly to do it on about the best-value, 200 amp, AC/DC TIG units available, at about $750, delivered and equipped.

    I mean, I'm guessing he'd get the same result on a Miller Dynasty 210DX, priced at around $4000, delivered and equipped.

    Of course, it would probably seem more foolish to do so on a Dynasty, somehow, even if beefing up the caps afterward made it more arc-gouge capable.

    Here's a more reasonable and normative duty-cycle test that includes the AHP.

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Just a heads up, I was having an issue with stick welding today, could not really get an arc going.

    It was due to me having the foot pedal connected, disconnected and the arc was back.

    Probably in the manual somewhere, but who reads them?

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Nah,

    This is his thread, and he's the AHP dealer. I've never even used a AlphaTIG unit.

    But, it's curious that he hasn't piped up, since his presence in this thread and on the forum itself has been pretty constant, till lately.

    Maybe he's on a Hawaiian vaction, sipping mai tais on the beach. You know, like that other AHP dealer and forum member here, Kevin Caron, who's currently on the East Coast of the Australian continent.

    Oh,

    Well, good.

    He's making some money then, and not sick or something.

    I suppose that's still not as good as the Hawaiian vaction and the mai tais, though...

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Wierd problem with my 2015 model alpha. I was just tacking up a project at 80 amps on 120v power. All of a sudden I get HF, but no arc. After 2 or 3 failed arcs I'm not even getting the HF buzz. I look over at the display and it now reads 005 amps no matter where I set the dial.

    I tried shutting the machine down and letting it cool for a while but the problem persists. I've also tried using the finger switch in 4t mode with no luck. Stick mode does not appear to be working either.

    I appreciate the help!

    There are fuses in the welder I believe. Also check your 220 breaker. Rare, but you can lose one leg of it.99

    If its under warranty call AHP. If Not here are a few things to check, make sure both fans are working. Check it on 220 volts. Did you try the foot pedal as well. If all else fails you can give me a call.

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Gentlemen!... First I want to say that since I bought this unit it has performed flawlessly! I've done quite a bit of mild steel and stainless and I couldn't be happier. My 1st project was a turbo manifold and it came out great even with my limited experience. Now I've done very little with it on the regular house line (110v iirc?), but even when I did, all I had to do was crank the amperage knob up a little more to get the desired output. On 220 w/50a breaker.... forget about it. FLAWLESS.

    So now I'm delving into the world of aluminum.....ughhh. And of course my 1st stab at it comes in the form of some VERY thin (maybe 1mm?) walled aluminum tubing. To add to the difficulty, this tubing is also anodized. And I don't know the first thing about welding aluminum, so I figured I'd see if any of you have had any experience welding similar thickness (.040") aluminum with this machine and if so what settings you used to accomplish the task? Thx in advance

    Re: AHP Owners/Users Thread. No Trolling unless you have used/own one!

    Glad to hear that you are having fun Lee.

    First thing about aluminum is that is has to be clean and bare. Anodizing is a form od aluminum oxide which is a a great insulator. It must be ground off (or dissolved with lye) before welding. Oddly, aluminum oxidizes very quickly when exposed to air, so you have to clean it just before welding.

    Common advice is to use enough amps to get a puddle within seconds and then back it off and lay a bead quickly. If you blow a hole STOP immediately so that you don't overheat the whole area and end up with more and more damage. Let it cool to the touch between passes to keep it consistent.
