Your video was super awesome and had great information for welders looking to better their craft. I was a NDT inspector in Naval Ship repair for many years. One extremely big thing you failed mention but clearly you had done is, emphasize cleaning! Oil left on the surface will contaminat the weld bead. Burnt oxides present after a pass is clearly obvious when improper or lack of cleaning prior welding aluminum. Any metal to be honest.
I find number 6 cup works very well. You can always change the frequency to help the arc smaller. You get a much cleaner weld if you use 5 % helium with argon. and will generate more heat.
These videos never disappoint me, who agrees?
I agree
This is by far the best explanation of this topic I've ever seen. Keep up the good work.
Thanks for the in-depth explanation like always Justin! Glad to see you back we all know you had a very busy summer but definitely looking forward to the next video! Definitely missed you! Keep it up brotha 🤘
Amen! Great to see u again Justin! Great video! CZcams has missed u indeed
First video I've watched where someone actually explains this properly, been struggling with getting the finer details of learning to tig weld ally and this has helped massively, thanks mate
Holy crap!!! That was super informative. I started experimenting with #12 cups with a gas lens on stainless steel and thought it would be good on aluminum. Sir, I am super grateful for the tip!!!!
Great video! It’s funny, I pretty much always use a standard collet body and 5 cup on aluminum. Earlier today, I had some aluminum to run and there was a gas lens on the torch so my lazy self threw on a 7 cup and let’er rip. Half way through, I thought this works pretty good.
Great Video. This actually solves a problem that I've been fighting. I never considered that my cup being to large was causing my issue. Excellent information. I noticed the issue but wasn't sure how to correct.
Same here
Awesome table set up there. Thanks to Nick for getting that aluminum up off the table so I wasn’t so hunched over last week in my class.
I wondered about that setup since I was out of town. I actually kinda liked the elevated platform myself. Nick is really awesome at coming up with solutions and I'm glad to have him on our staff.
@@TheFabricatorSeries Yeah he was great... only problem was he got me to buy a new Optrel 2.0 with 2.5x magnification lol. Being able to see the arc and everything up close with the magnification was a game changer for my stainless work.
Still wish we could have chatted about our Vipers while i was there. Maybe next year when I'm back in Vegas.
Great explanation of what I have experienced running an 8 gas lens.
Great video! I was talked into a large gas lens a couple years ago. After watching this, I threw my original set up on my torch with a #5, and laid down one of my better aluminum welds.
This was an exceptional explanation man, thank you. You have that rare ability to explain stuff so regular humans can understand, thank you.
I've been Tig welding for many years and never really put thought into the cup size for aluminum. Your explanation makes perfect sense. Thanks for taking the time to explain to us mortals!!
Order some more metal from Weld Metals the other day. Just came in the mail yesterday.
Trying some of the thin metal this time.
Being a self taught tig welding rookie, I learn so much from your videos. Thank you for the awesome content.
I’ve been combo welding for 17 years now. Struck my first arc when I was 10 years old. But This is the most detailed explanation video I’ve seen. Makes me wonder if I should be a CZcamsr lol. Well done man. Keep burning and earning
For the love of all that is weldable, please keep doing these aluminum tips and explanation videos.
Great video. I've been using a #7 gas lens since forever and I can't even remember why anymore. It has always just worked form me. This has motivated me to try a #5 and see what I can see. I completely understand the "boring" technical theory here which I would like to see in practice for myself.
I find myself watching this video, without any preexisting plans to start welding. I don't know how I got here, still I have watched several of your videos. I don't have any reason why I need to weld, still I'm trying to persuade myself not to buy a TIG/MIG-welder... But it is tempting!
I think the way you present the subjects and the format you choose contribute to that success. So keep up the great work!
I’ve watched 2 videos so far and have learned more then I have ever about welding in the 2 years of experience I have.
That explains why my 6 looks better at my shop than my weld at a friends with his 8. I need a smaller yet obviously. My buddy's welds all look like your #8 examples. Thank you sir.
Hey welcome back Justin been missing your videos! Love the how you explain everything exceptionally well keep up the great work!
Makes perfect sense & like you said in other video's, stick to the basics that have been tried & true since the beginning.
such a simple concept that can completely change the look of your welds. ive always wondered why i kept getting more and more cleaning action on my welds despite having bigger cups and higher CFH lol well now i know!
Natural teacher. Wish I had him in high school.
thanks for clearing that up.
1:15 Observation - Everything wasn't the same between both welds - your distance from your work to the tungsten tip was different between both welds and caused your arc to wander. #5 cup is fine but 18CFH Argon would give better shielding w/ 189 amps Electrode negative / 120 amps Electrode positive w/ a 74% balance @ 130hz using 3/32 filler.
Using a Furick clear cup gives us the added vision in tight spaces instead of using a ceramic cup as we can see through the Furick cup.
Not mentioning your machine settings leaves the guy who is looking for guidance in the dark. We'll mention dwell time on arc starts and travel speed also as most novices tend to get a puddle and get moving which causes a lack of full penetration.
Take it for what it's worth as we're all learning something each day.
Cheers and Happy New Year!
Glad to see you again.
i simply cant run a Ally5 as good as 8 pro glass. especially on outside corner joints where gas coverage is harder to achieve. i could care less about a etching line cause in a few months it all looks the same.
Just started to Tig aluminium it's been 3 days adjusting amps, AC Hz, AC balance I'm getting better but it wasn't till I put a No 5 cup on that I saw improvement. Thanks
You have just explained some of the problems I'm having. Thank you. 👍
You were/are the gateway to my welding life. Thanks so much man for giving me the joy of knowledge to create
great explanation, I had never heard before
I used to use GAS lenses on Aluminium, but with the AC frequency + cycle spitting oxides into my tungsten and reducing the life of he Gas lens, I decided to go back to standard collets. My weld quality has actually improved. And I'm saving a fortune on Gas Lenses. Now I only use Gas Lenses for Ferrous metals, mainly SS.
Heck yeah Justin!!! Keep em comin still Savin up for that prime weld
one of the best aluminum welding explanations I've seen. bar none.
what was great is that your explanation matched my observations in the last month where i tried a number ten furick cup.... needed twenty five cfh... random arcs... etc. thought i was doing something wrong.
also noted, like you said, i increased the stick out... helped. but needed an additional 2-5 cfh... so by the time i get it running right... it sounds like a hissing snake spitting money during post flow lol...
awesome to see you making new vids... thanks!!!
I make hardtop cabins for 30 foot aluminum fishing boats, and I generally use a #6 with a little bit of stickout for TIGing grab handles, corners, etc. Seems to work alright. Used to use a 5 but it just never turned out quite right.
Makes total sense now! I was using a Fupa cup on stainless but then switched to alum and noticed it was very hard to put down good welds. Now I know why, I'm going to try this later today!
Couldn't agree more. Cup size has always been very important to me as well.
I was running a #6 on 15cfh argon. I'll switch it to a #5 and 12cfh and give it a whirl. Save a few cfh... literally, lol. My issue was dirty aluminum that I got out of a scrap pile. Cleaned it with a stainless steel brush and some acetone but was still getting black shit in my weld pool. I put my torch down and put in an order for 40 coupons from Weld Metals Online. It's on it's way. Thanks for the tip!!!
Thank you for sharing! I usually use the #8 cup. I'm going to try the #5 tomorrow! 🤘
Interesting - I've been running a #6 at 15CFS Argon on 16gauge coupons, but I'll try a #5 today and see how it works out. Thanks :-) solid explanation.
I think it’s always useful to know the why’s and how’s and not just the rule of ‘if-this-do-that’
Great video. I only have a stick start DC tig so I can't do aluminum, but these vidoes help me to know for the future. You are top notch for teaching videos.
Nice vid, i had a hard time figuring this out when i first started
Holy crap! I never knew! This all makes complete sense. I never would've thought of that. I've always used a #8
Glad to see you back. I learn shit on every one of your vids. Thanks man
With the help of your videos I was able to get proficient enough with my TIG setup to custom make a twin turbo kit for my 350z. Cheers.
Depends what your gonna do though , if im welding something really thick on crazy high ampa that small 5 cup is gonna glow like crazy
While I always enjoy your videos, this one was especially informative! Thank you very much! Please keep them up!
So good for a beginner like myself.
Top shelf production too!
This video answered a lot that I always wondered about welding aluminum. Glad to see a TFS video again!!
Awesome thanks for explaining, i was using a #5 and got my weld ok, but was told I should be using a #12 cup and have been struggling with it ever since (I have about 15mins total tig welding with the new machine). ill switch back to the #5 now thanks!
Excellent video! These are things I already knew, but the reverse dartboard explanation was just great; and I’ll definitely be stealing that when I have to explain this in the future👍🏻👍🏻
Lol... I had no idea that a #5 or #8 was the preferred cups by seasoned aluminum welders... I've been welding for 20+ stick, mig, fluxcore... 4 years ago I returned to a old job and noticed a lincon 370 precision tig machine just collecting dust.
So I hooked it up and became the aluminum welder lol, long story short I run a 1/8" gas lenz with a #8 cup just because it felt right😂
I use a #6 gas lense sometimes because thats the only 1/8" consumables I have and i happen to have a piece of 1/8" ceriated tungsten 😂
@@ButBigger42 Dude, what if I use a sharp, large tungsten on a small cup? I don't know why it is better to use tungsten for low amperages. A large tungsten can still transmit low amperages, but will it consume less? Quite right?
I've tried all the cups, there is about 2mm etching difference between 5-12 with the stubby gass lense however if you turn the amps up the smaller cups don't cool the weld enough so my findings are if you use more gas you end up with a shinier weld which I'd prefer over 1mm of etch line
Interesting. I've ended up with a number 8 gas lens as my preferred setup, mainly because I like the extra coverage as it helps stop impurities, especially when working with old bits of cast. I'll try the 5 again though, it's been years since I did.
Thank you for this! I always used way to big a cup and now I see why I had problems..
Thanks Justin, this really helped a lot. In areas where I absolutely can’t get rid of gaps, I’ll run a #7 gas cup and stuff filler, but took your advice and the standard 5 is such a tighter and better look. Always appreciate your videos. Thanks! 👨🍳 💋
Best cup explanation on youtube .
Ty sir.
Great tip! I have been using a #8 cup with gas lens and my welds look just like yours with the same gear - well close anyway. Filet welds especially are difficult to get into the root without excess width. I'm off to the shop to try the #5 cup and standard body with high hopes.
Great video! Thanks for sharing. I would live to see this setup on a CNC. That way there is absolutely NO difference other than the cup. I'm sure yours is close but you can tell the dip was different at a minimum. Regardless. Thanks!
Thanks for all the information on all the Videos!!!
Literally been welding mild steel for 20 years "stick and mig mostly" well after an accident, i went back to my old job and...
POW!!! A TIG MACHINE was in the courner and nobody was using it.... so i rolled it out and started learning aluminum "very seldomly throughout the week" after a year i convinced the boss to buy a lincon 375 watercooled something something😇 and this is the first time ive heard that the edching zone is affected bye cup size... course i been using a stubby #6 setup, so thanks,,, pss... aluminum isnt so bad once you catch on how to work it
as always very informative and straight to the point! thanyou so much you are literally the best welding teacher on the net by a long shot!
I love the short and sweet videos packed with tons of info!
Glad to see you back Justin.
Very good and informative video. Giving the theoretical explanation and examples goes so much further to explain.
Great stuff Justin... thnks buddy I really appreciate the sharing of your knowledge... Some day I'm hoping to make the short trip up to take a class from you and finally meet you....
I'll try this instead of my no7 standard cup then. great video
Happy to see you back!
I’ve learned a lot from you Justin. Thank you.
All I can say is thank you! Simply explained!
20 cfh is a bit high for a # 8 cup, creating a Venturi effect. I run my argon between 12 7 14 cfh with that cup. Keep in mind I am not using a micron flowmeter so gas flow may be 10% either way.
Thank you so much! I watch this from Germany, where is only one good weld channel on youtube. American weld channels are much better.
I like using a lave cup on aluminium used to use them when building boat towers
We've missed you! Welcome back. Great video.
So if a smaller (#5) cup focuses the arc better, in which circumstances would you use an even small cup? Like a #3 or 4 cup?
Again, excellent explanation and makes total sense. Keep all your tips coming!
Thanks Justin Great info
I specialize in welding aluminum from my personal experience the gas creates a medium with the same flow and amperage a smaller cup will always produce a tighter nicer more uniform weld And it will also weld faster. However to small a cup will cause a problem on thicker materials. My suggestion in most cases use the smallest cup that works for the thickness of aluminum you’re welding.
Well explained …. That was my problem from the beginning. Thanks man 👍🏻
Thanks Justin, awesome as always
What ever happened to the project cars?
Glad you back. Merry Christmas to you and your family
I usually run a nr 8 cup, but then again, I weld alot thicker stuff than intercooler piping. Found out that a nr 6 is too, small, not because of the lack of heat in the weldpool, but the cup explodes due to the heat when running 280+ amps for an extended period of time
I could and HAVE watch ur videos all day lol. So much good info and learning. Keep up the great work man!
Exelente videos! Gracias por compartir!!!!!! Sería bueno que los traduzca a español! Un gran abrazo desde Argentina!
Justin , always great stuff.....cheers from Florida, Paul
Well it appears your dip speed and the speed you were moving the torch were a bit different. I use the 8 with gas lens and it looks the same as your 5. Nice looking welds though guy.
well done.... thanks. I love a #5 on aluminum
This was a most excellent and helpful discussion. Thank you for taking the time. PS just ordered the stubby 5 non-gas lens package.
Thanks for all the great content. Could you make a recommendation on a tungsten sharpener? Thanks again!
Nice Video!
You should teach at the University, not even a Professor could explain it like you. 👍
Thank you for the information, YOU have been missed....
Thanks !! I just learned something ! 🤘🏻😎🤘🏻
Wow, lots to apply now. I was wasting argon..jacked balance up to 80% electrode negative with 150 Hz when I could have dropped to a #5 gas lens.
As usual, a very clear and excellent lesson.
Excellent excellent excellent! Thx

Thanks for the info! I was just wondering about this the other day, guess I need to get some new cups!
