Aluminum argon vs helium, vs mix? - weldingweb.com

Jan 19, 2010· The only real bummer to straight helium is the arc is harder to maintain. A mix with just 10% helium gets a lot better penetration. There are ready made mixed bottles out there; not from my supplier, but there are members who get them. I have a mixer, and do it that way. I use a little 40cu. bottle of helium and add it when I really need it.

Suicide/Suffocation/Helium - Wikibooks, open books for an ...

The helium suicide method has been used widely, including reportedly by reputable organisations like Dignitas. (Dignitas now uses only a drink of 15 grams of pentobarbital sodium: trade name Nembutal).The helium method is based on the fact that breathing inert gas like helium does not produce any feeling of suffocation, but depletes the body of oxygen, leading to loss of consciousness and death.

What shielding gas should I use when welding aluminum?

The helium content gases are usually more expensive. Helium has a lower density than argon and higher flow rates are used when welding with helium. It is possible to increase welding speeds in some circumstances by using helium and/or helium/argon mixtures. Therefore, the extra cost of the helium mixtures may be offset by your improved ...

How to Choose the Right Welding Gas - Kevin Caron

Wherever you get your bottles filled, tell them you want tri-mix (argon, carbon dioxide, helium) if you're going to work with stainless, do MIG welding, or aluminum MIG welding. It's a great mix for doing this kind of work with a MIG. Now, with the TIG welder: straight argon, nothing else. That's all you need.

Cleaner weld on Aluminum w helium mix than straight Argon?

Dec 07, 2013· Cleaner weld on Aluminum w helium mix than straight Argon? Some of my welds as of late have been almost of the verge of burning despite no changes in technique or machine settings. What I did notice was it happened as soon as I bought a new box of Harris rod. I forget the last company, but it was much more forgiving.

Can you mig steel with argon? - weldingweb.com

Feb 14, 2007· I've heard yes and I've heard no, it doesn't "sit right". According to my old boss you can subtitute argon for steel but not argon/co2 for aluminum. Argon for steel seemed to work all right when I did it but how does the weld measure up strength wise I wonder. If anybody's got the answer for this question out there I'd sure like to know. The guy who said you can't was selling the mix for more ...

Tig Welding Info - Welding with Helium AND Argon

Helium for Tig Welding Steel. But there is another use for helium, helium mix that is... if you have a small inverter welder that only puts out 100 amps or so and you have some pretty thick steel to weld. Using a helium mix makes it penetrate a lot better. Sometimes even too much if you are not careful.

different regulator for different gasses? - Miller Welding ...

Therefore a welding gas mix that includes helium can throw off a flowmeter's reading significantly if read on the argon scale. My flowmeters have a helium scale and I suppose if I used a blend containing helium I would have to extrapolate between the argon and helium scales using the percentage of helium in the mix as the determining factor.

Week 5 Flashcards | Quizlet

The silvery Mylar bags used for long-lasting helium balloons barely stretch at all. Once you have filled such a balloon to the point where it is taut, it becomes counterproductive to add any more helium atoms. If you add more helium to a taut Mylar balloon, its weight will
