Tig Welding Aluminum Helium Argon Mix

[donnyp1966]

Helium has a much higher thermal conductivity than straight argon. Argon is a dense gas that gives good shielding at low flow rates. Also,argon-CO2 mixes are primarily for mild steel MIG welding using short-circiut transfer. I have run MIG spray arc using AG-2 (98%argon,2% oxygen). 5% or less oxygen is safe from porosity.I know it doesn't make sense but it's true.I've been a welder for 18 years.

I'll agree that the dynasty 200 is a good machine, but its begun to die on me lately. I had a 21ft skid loader trailer come into my work with a broken storage box in the front, and needed a 4x6 piece of 1/8in 5052 diamond plate welded to the back on the loading ramp. And for some reason it won't puddle for like 3-4 seconds on 200amps maxed out.

@GameFishermen I had a dynasty blow up on me...the compasitor blew and it was like a hand grenade going off...paper everywhere..shit in my pants

What about the 20lb throwaway helium tanks for ballons?

think its clean enough?

100lb tank of helium would last me forever!

Also my gas suplier wont take any new orders for Helium says theres a shortage.

what preasure of argon & helium?

hey mate about those tig finger heat sheilds do they get shipped out to australia

[morgorth3242]

can you meld metal with a tig with Welmix 15? 85% argon 15% co2?

and can you use a tig tool on a migmag machine?

[TSorovanMHael]

@morgorth3242

1) NO! Adding CO2 to your shield gas will result in slagging both the aluminum and your electrode to a lesser extent. Al is pretty reactive towards CO2. You might be able to use it for DC welding steels in a pinch. However 15%CO2 is an excellent all-purpose mix for MIG

2)No. MIG welding power supplies are of the "Constant voltage"(CV) type. TIG and stick need "constant current" power supplies (CC). Trying to TIG with CV would make starting and arc control almost impossible.

I like the use of the heat sheild mesh on your torch hand.. great idea.

I use a mix of argon/helium through a company in Canada called "blueshield" there are 3 mixes. 1=25% helium to 75% argon

2=50% of each (my favorite for sure)

3=75% helium and 25% argon (super hot)

this is a great way to teach those who can or want to weld. Thanks for the tips and tricks.. your never too old to learn.

jody your the men !!!!!!!!!



[Takuan66]

What's the thing on your pinky? Where can I get one?

[Broadcast1Channel]

@Takuan66 Look 7:52 in to the video looks like you can get them on ebay.

[TokinCamel]

i gotta say..who would dislike this. its like sayin "oh, i dont like what you do for a living" :P

[TheJr420420]

id have to say this guy knows his stuff!!

[Helpmefly]

Great vid!

The only drawback would be the higher cost of helium, here in europe. How much more does helium cost in the US compared to argon?

[TSorovanMHael]

@Helpmefly it's still about 2-5 times as expensive as argon, depending on supply/demand. He is cheaper in the US because we have large reserves of natural gas, and a lot of our gas wells have a higher-than normal percentage of helium. Also, it's questionable to be using He for trivial things like welding or balloons, since it's a non-renewable resource. There are some technical and scientific applications which simply won't work without helium, most important being MRI machines.

[Hector49er]

I LOVE the Syncrowave 250. I learned TIG on one of those. I'm going to be practiceing on a frind's one soon (hopefully). I want to get back into it.

[djembe29]

Thank You Thank You Thank You. Can't wait to try it. What an awesome way to get more out of your machine! I would also like to know how it works on steels?

[MASSEY4201]

Would a Durafix Rod work better?

[phantomangel19]

ya with my dynasty 200......i used thoriated tungsten the other day and wore it our was welding half inch alu. at 120 amps lol which was awsome and it came out beautiful hahaha anyway does anyone know how much the boards are if u were to fry one of the millers ive heard they are alot but so far with it, it would see it would be real hard to do

[wwwracingpartsro]

is this 80% helium + 20% argon good on stainless steel? or is it just for the aluminium? thanks!

[G30360]

thanks for sharing this

[BigDub2010]

i hope u didnt really mean sharpen the electrode lol. but yeah great vids! alot of what you have made videos of has really helped me when im welding. thanks a bunch! 5 stars!

[TheRealPinkNinja]

@BigDub2010 Why?

Sharpening is possible... On any machine that uses square-wave technology, or an inverter, can use other types of tungsten OTHER than just pure tungsten....

having a tungsten with a sharpened point focuses the arc in one spot. Much more stable. as the arc isn't wandering all over the place...

You can almost all types of tungsten for aluminum

[BigDub2010]

@TheRealPinkNinja idk i was just taught in school to use a rounded tip on aluminum

[TheRealPinkNinja]

@BigDub2010 I was taught the same thing in school... But once you get out there you'll quickly learn that you really don't learn a lot in school, lol

If it's a transformer type welder. You can only use a balled up Pure Tungsten for aluminum.

Any inverter or TIG with squarewave technology can run almost any type of tungsten. Balled or pointed. If you have a chance to ever try this. Try using Zirconiated Tungsten with a sharpened point on aluminum. It's absolutely awesome.

[BigDub2010]

@TheRealPinkNinja lol true. and alright i'll see if i can try it sometime.

[2alejandro2008]

Great job as always Jody! Thanks my friend!

(non-ETOPS)

[reflectionlabs]

always fun to watch your videos

[chizzy555]

btw some 1/2 inch welds would be interesting

[chizzy555]

thanks for the vid much appreciated, but i got a question if you dont mind answering, why would 80% helium be different than 100% argon? why is there a difference ?

[turbotrana]

I tried your tig tacking method yesterday. Very useful.

How about showing some thick stuff like cylinder heads. Whilst I can do it, my stickout can only be minimal (like 1mm) for it to work but I have seen it done with 3mm+ stickout but it does not work for me. Gas lense helps alot.

Getting good gas coverage is the most important point I missed when self learning aluminium and helium mix a must.

i have only stick and mig welded but this is very cool
