This is cool I mean obviously I didn't know that you could do this and I'm just a beginner welder myself so thanks for the video but is there any instance where I mean obviously AC is and just running argon is cheaper and just straightforward so is there any job or some kind of instance in a project that this would be more of a requirement or a better solution or better freezing to do this by doing the more expensive weld obviously with the helium and the mixture and you know all that kind of stuff having to go on compared to just your straight argon and straight AC welder sorry about going all the way around my elbow to get to my thumb there but I'm just trying to get it explained the best way in the how to we use AC today and AC seems to be working just fine maybe the point of this video to show that you can use DC but I'm thinking more like is there certain things that might be built that this type of welding with The helium and the things like that would make a better weld or stronger weld and hold better because of whatever kind of situation maybe pops knows a a job that would benefit from having to do the extra money in the extra spending for something like this thanks God bless
He explained this in the first few minutes of the video, but I'll try to answer your question. If you can find helium to run dc aluminum, you'll get better penetration on thicker base metal with less preheat and fewer amps, thanks to the way helium acts with the arc. Unfortunately, helium isn't just expensive, it's hard to get now. I live in Las Vegas and I have to send a bottle to salt lake city if I want it. AC is just more practical in every way. If you absolutely need to weld aluminum and all you have is a DC machine, this is how you do it. These days, with inverter machines, there's really no need to run straight DC on aluminum. There is an advanced pulse program that some machines can run that switch between AC and DC- for a very short burst while still using 100% argon. It's amazing how much more penetration you get from just a blip of DC-. Anyway, have a good day. Cheers.
So thickness plays a huge roll in why welding aluminum in dc is superior. When welding aluminum it dissipates heat very quickly but welding dc using helium is very deep penetrating and inputs the the heat quickly so you can achieve a quality weld without all the tungsten spit of AC. You can weld 1/2” aluminum plate without preheat. Try welding 1/2” plate on AC without preheat and you can compare. I used to weld 2” thick aluminum molds with minimum preheat with 0 failures. We tried welding with AC but we had so much tungsten spit even with keeping the part hot that we decided that it was more cost effective to use dc with 100% helium. Hope this helps. If you need a more comprehensive explanation I will put another video out with moxie.
I love the fact that pops had the old school knowledge. I learned welding a long long time ago. This is back when a continuous bead was considered more professional than the "Stack of Dimes" look. So I completely understand his point of view. I would love to see you and pops do a future video using flux covered arc rods to do an aluminum weld with 100% argon on DC.
Great video, I always wondered why you were supposed to ground a flat spot on the Tungsten, ??? Maybe you could do a video on independent Amperage Control how best to use it when welding Aluminum.. Thanks
You have to use a porcentave of argon and Helium. Example; - 75/25 or even 50/50 like for Brass. The more Helium the more fluidic and cleaner the puddle Becomes.
Is it normal to look black like that? Is it because of the helium/ being hotter?. Thanks for the vid tho..only good video I could find about DC tig for aluminum. 👍👍
Just stumbled across this channel, and have to say I'm really impressed. Not just the detail, but more importantly, the attitude. Can I assume you are using Zirconated tungstens for Aluminium ? Greetings from Melbourne, Australia.
In the “old’n” days it was called heli-arc welding for a reason. It was dc welding aluminum with helium gas. As he said using helium gas the electric arc travels across to the base metal easier (thus increasing voltage). AC current welding aluminum has a cleaning action in one half of its phase. If you look closely at most tig machines you’ll notice a diagram of the weld puddle during the different times in its phase. The dc portion will have a narrower bead face with deeper penetration, while the ac portion is a wider puddle with less penetration; adjusting the knob setting between the two is determined by the thickness of aluminum you’re welding.
If you have been welding as long as you claim the reason, we A/C WELD is to break the oxide layer away . D/C does not break that ceramic layer away, which can be introduced into your weld pool .This is the reason D/C is no longer used .
I learned that a long time ago from an old timer, and have been welding for many years. I went to welding supply place to get some supplies to weld some heavy aluminum, and a fresh tank of argon. Dude at the place told I didn’t know what I was talking about and that there was no way to DC Tig weld aluminum, I took the parts in after and he didn’t believe me even when I showed him.
So my machine i bought without researching from my my Mac Tool guy, the one thats only DC tig i can tig aluminum using helium for my shielding/cooling gas.
AC is the most common aluminum welding you’ll see but DC is more for thicker aluminum, deep penetration, for clean welds no spitting like AC, and weld speed.
@MrBuboyangeles Absolutely! Argon gas cleans the weld puddle better than helium. But, as with all processes of welding there are better ways of doing things. If you have an ac machine, the ac electric phase of your weld cleans the puddle better than just the gas. If you’re welding a thinner plate of aluminum that doesn’t need the “increased voltage effect “ that you would get from helium gas, then by all means use argon gas. Mechanically clean the weld area very good, first.
@@scidork in every material u'd better clean base material, but if you know what you are doing and what'sthe use for the parts you are welding you can skip this part, especially on aluminum; you have ac current to clean the material and as long as you have just to clean some oil/wd40 and so on, you can just burn it , wait for the puddle to be clean and add material. obviously she described the way to go that a teacher would teach you at school; but in real world things don't always get done how they teach you at school: you have to know what you are doing. Helium is just useful to her because she has a small welding machine capable of 255 amps peak current: helium is a hotter gas than argon (can't really explain in english, but at same amp you'll have increased volt of your arc with helium mix, approximatly 18 v with helium mix vs 16 volt with argon; so it will be like having a bigger machine, but also the arc with helium will be more focused and the alumin won't be able to spread heat that much on the part); but keep in mind that unless you live in the usa, in europe helium is crazy expensive and if you regularly weld aluminum, especially thick stuffs, it will be cheaper to get a bigger machine, in the range of the 400/600 amps, or if you can, preheat the parts. there are so many different ways to get the job done properly, you need just to get some experience: if you do it 8/10 hours per day as a job, u'll quickly learn what you need to do. tig welding is about a good hand and being able to control the puddle, so you have just to know what to look at; if you are good enough you don't even need a support for your hands, it's just practice
It's sad the world we live in where people are scared or reluctant to use God God created all that we see God gives us life everyday God is all there is there is no other escape from this planet you will not get away from God you can't hide from him here and death will not give you a reprie so far as I'm concerned God out with pride cuz that's one of the reasons why our country is in the situation is in now is because the people that believe in God live for God they wanted to be I don't know social or whatever but the Lord said come out from among them the Lord said this is not your world we are not a part of these people here there's a difference between the world and the church the people that are God's people and we have failed the world by not standing with God and on God and his work and now children are having terrible things done to him now we got chaos everywhere and it all comes from a lack of God so if you ever have another video that somehow another God comes up in it or the word God don't be don't let the devil have this victories lack of a better word there is no better word other than the name Jesus loud and proud praise God each and every day with all my heart all my mind all my strength with all my body in Jesus name keep up the good work on the channel pretty pretty good so far

heeeeeeyyyyy congratulations 🎉🎉

have a good day doods. ia asm your new subscriber. thnks the video you upload.
Dang, people falling out of the air! definetly gonna start cleaning my material before I weld... lol🤣😂
I still use dcen today on heavy aluminum plates it speeds the welding process up !!!
Great video. He seems well versed in welding
Wat tungsten you runing just the red
Pops did a nice job and is a good teacher, so keep applying Prov. 19:20 for your benefit.
Absolutely! Perfect scripture for this! Ya there’s always more to learn!
Hii
Can we use other gas types?
Did you use red tungsten or green tungsten?
Can it be possible to use only argon gas to dc tig?
Argon doesn't produce a hot enough arc the burn past the oxide layer, you probably could but it would put down anything halfway decent.
@MrBuboyangeles Absolutely! Argon gas cleans the weld puddle better than helium. But, as with all processes of welding there are better ways of doing things.

There's no reason in the world to do that: it's 2022 guys, just buy an ac/dc welding machine🤦🏻♂️
Both AC and DC call for cleaning all the materials and using the correct filler rod, so the only difference I noticed was using helium, right?
