there have been a number of discussions here and elsewhere about how flow meters are calibrated, and the output pressure is a factor. Since the gauge/scale on the flow meter is calibrated for the output pressure of the regulator I would think you'd get a different number if the peashooter wasn't ca...

I use the pea shooter (aka floating ball) type flowmeters at the tank to begin with. So where do I set it? Just there at the tank. If I get porosity, I adjust the flow as needed, regardless of what the numbers on the flowmeter say. IOW, if it's too low, it's too low; and if it's too high, it's too ...

It's only on the home page. Once you go into a sub-forum, it's no longer there.

15 CFH is fine if A) you were using a much shorter tungsten stickout from the cup, or B) you were welding an inside corner type of joint that naturally traps argon and keeps it lingering around longer. I would say either decrease the stickout to half of what you are presenting OR bump it up to 20-25...

click the little icon on the right that has the double arrows (left & right). That toggles the sidebar. That's all I can offer.

Why is it bad on your laptop/desktop? Seems fine to me. Different, yes, but fine altogether.

Close to your budget, and even though it is out of stock at the moment, but this is a quality machine that I would recommend: HTP 210 MTS . I have the pulse-capable version of that one and unless you are doing more than medium-level fabrication type work or need to constantly weld 3/8"+ steel/a...

That's what I do.

I'm under the impression that the MDX gun that Miller supplies with the 255 was developed to work with pulse. Yes, basically any MIG gun will work with pulse, it's all about how much heat it can handle and if there are high-heat tips for that MIG gun. The MDX will be better than any mig gun that is...

At what proposed amperage levels do you plan to pulse weld?

A billet what? Of steel? Of Aluminum? Of copper?

Concept of Pulse Current Gas Metal Arc Welding Process

Experimental Approach to Selection of Pulsing Parameters in Pulsed GMAW

Metal Transfer in Pulsed Current Gas Metal Arc Welding

While I don't have experience with manual pulse settings, I do have some "white papers" that I could share if you care to read through them.

well how did he check to see that it is "almost full"?

This is quickly becoming all about amps. Like cj737 said, with aluminum it is ALWAYS about amps when using a standard TIG approach with only Argon shielding gas (and assuming everything else is in order). You simply need a buttload of it at the beginning, especially with small parts, as they will r...

1/4" aluminum with only 160A is way, way outside the box...like double the thickness you should plan for with that size machine. Pre-heat will obviously help, but I'd be looking to find a way to add helium to the setup as well. I've tried 1/4" aluminum with a 200A machine and it was possi...

Yup pretty much. Aluminum does not take well to autogenous welds.

Sorry to dig this up again but I figured this might be the best way to possibly get some of older posters on here to come back and give their thoughts. So I've been debating a button for a bit now but I'm curious, how have they held up long term for you guys? And what kind of shop do you use them i...

Sounds like your gunna have to bump the pedal or trigger after your bead to keep the gas flowing. Sent from my Pixel 3a using Tapatalk Exactly. If it is set for only 2 seconds you're going to be in for a world of exhaustion with so much tungsten cleaning. If you're dead set on using this machine, r...

Your question is about volts but your diagram is showing amps. There might be a slight phase difference because of the reactance of the arc but the waveforms will be the same shape. I am asking if the low current DCEN section is simply interrupted by a periodic but otherwise typical AC TIG current....
