If one was to cool air down to a liquid, how much of it would reasonably safely fit into a G size cylinder (which hold about 353 cubic feet of oxygen I think)..?.

Thanks for the informative video. I am still confused about settings for spray transfer when welding aluminum. Spray is certainly achieved using 100% argon and voltages certainly less than 25 volts. Why is this? Suggested settings on some welders for aluminum spray have voltages around 18 volts whereas other machines set about 21 volts. Are these differences just related to the machines’ idiosyncrasies?

What about with solid core wire?

Sir, May we use 70 argon 30 c02 for welding in instant of 80/20 for cost saving

Why TF you leave out the sound of perfect arc??!

How can that lead seal melt at 212f when the melting point of lead is 621f? Did I miss something? 😊

Amazing video!!! I wish they taught this stuff in High Schools...seems like very good common sense. God bless you sir!

Thank you, bery informative. I believe you can obtain spray transfer mode when mig welding aluminum at a much lower voltage?

Does the argon helium last any longer or is it just a gas in the bottle

Thanks, you answered my questions expertly

What about aluminum wiring

Good sir nice demonstratration ❤❤❤❤

Great information about GMAW method , thank you Sir !!

If argon reduces smoke and increases deposition, why can't we run on 100%argon as we do with aluminium or tig?

Brilliant video and explanation. I've been using spray transfer on 8mm plate, horizontal fillet and vertical down fillet with really good results . I like your video because of the possible problems and how to rectify them. Great job 👍

Thank you for the vid!!!!!

and doesnt hold up the actual cables to gauge real world size..................idiot

Thanks for the explanation! It helps to see a person standing next to the cylinders to help aid in figuring out how heavy they are and how to move them around.

Probably one of the best videos on spray transfer and how to manage it with machine settings.

1:49 vThe camera is not from the same ange

Good to know. ty

You can buy any size cylinder. Including 300 cf.

So do you have to push or can you pull the puddle with spray transfer and can there be oscillations or manipulations such as arcs or cursive e's or does it have to be a straight push or pull?

Every one of those bottles can be customer owned.

Thanks for drilling down to usable information in all of the videos I have watched so far. I can't work out why you don't have a huge following.

Just because your company only leases the larger cylinders does not mean that they are only leased cylinders for everybody. Where I live, you can own any cylinder, and refill any size.

Hi im in the uk using C15 ( 85 /15 ) here's my problem ? we use 0.039mm wire ( 1mm ) so what would be the optimum parameters for welding using 27.5 V what would my wire speed be yours is 600 Ipm I need a Meters per minute approx Thank you for the Video

The DOT-3AA is not specifically a steel material designation, but rather a cylinder design standard. Take a look at 49CFR178.37. The hydro static test pressure is also 5/3 times the marked service pressure. www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-C/part-178/subpart-C/section-178.37

As a welder of 12+ years, I gotta say...this is great information. Took me trial and error to learn many of these.

Explained very comprehensibly

this is a great comparison thanks...

Best video yet ,very good .

🇺🇸👍👍👍👍👍👍👍

Dude...... read your charts before "giving a lesson". Your own charts contradicted you, both charts!

I'm not sure why you're saying you need a minimum of 80% argon for spray tranfer, when the very chart you posted @ 1:25 shows the exact amount of argon mix needed. 98% is the minimum needed for true spray tranfer.

What you're talking about is still globular tranfer. For "true" spray transfer, a mixture of at least 98% argon is needed with 2% oxygen on mild steel. 99% argon and 1% oxygen for stainless steel. See "The Welding Handbook, 9th edition, Volume 2, Table 4.1. Globular to spray transfer currents", as per the American Welding Society.

That demonstration is misleading, you can’t see argon so visually co2 make a larger, VISIBLE cloud, science involes facts not opinion.

I just bought a 125 cf cylinder brand new from Amazon it is definately customer owned so your info is wrong

Thank you for this video

Even that first weld was awful. The entire thing had undercut all along the top. Spray is so hot that you should never EVER use it on thin material like that. I use spray transfer at work every single day and they should never ever look that way. Spray should look very similar to pulse MIG in the flat position and have the distinct freeze rings you'd normally have. Not to mention your travel speed. See how fast you're having to go on that dinky little 1/8" material? Spray is not meant for metal that thin at all. If you really want cleaner welds with thinner metal, use 90/10 gas at like 22 volts or something. Your freeze rings are shaped like a bird's beak.

What do you mean 125 can only be rented or leased? I own a 125. With a slick neck ring

Extremely good teacher. Thank you for your clear explanation. One of the best videos i have seen over the years.

Pity It won’t allow me to upvote this video more than once

He using 035

So all this info pertains to dual shielding?..

Great video. Very informative. Thanks you.

Very informative !

is there a general formula to compute amperage for a given voltage & wire feed speed?

Excellent lesson Nathan, many thanks!
