Which TIG Cup Should You Use?
Вставка
- Опубліковано 3 лип 2023
- TIG cups can be really confusing. Which one works best? Which cup works for which metal? Does the size matter? How do you set up your TIG cup properly?
All of these questions and more will be answered by Justin from @TheFabricatorSeries in this deep dive episode all about, you guessed it - TIG Cups.
Learning what the cup sizes meant (16ths of an inch) was helpful. Learning the gas flow range based on that size was great!
I had to learn by trial and error and a little bit of advice from some older guys. You really didn't get much input from some of them until you got put brother in-lawing some pipe with them (I learned on pipe that was getting x-rayed to code). Luckily when I started doing aluminum and thin sheet metal there was an older guy around who didn't want to do them anymore and he taught me a bunch.
I just love freedom units
This is an absolute great video! So much information that will help save money and get good welds!
The most expensive parts I bought as a newbie were cheap parts from Amazon. Such a waste of time, tungsten, steel, aluminum, argon, etc.
It's a lesson we all must learn. Even Justin tells the story of when he bought cheap consumables.
Notes for myself and for you as well
Cup# measures 16ths of an inch on diameter.
Tungsten stick out should be around same as diameter.
Min CFH = cup# * 2
Max CFH = cup# * 2.5
#5 aluminum
#8 universal (steel, chromoly, etc)
#12 stainless (pretty colors)
#16 titanium
Love your no nonsense straight talking approach, keep it up.
Justin! This video was the turning point for me! My aluminum welds were looking gray or ashy. Not sure how to describe it. I went down to the standard #5 cup, and I put the stick out just like you said, and then I had to turn my argon flow WAY WAY down. Holy crap, now the welds are so much cleaner. They are bright and shiny and they look 300% better.
Mistakes of mine were that my tungsten was far too stuck in. I thought I needed to be WAY up close to get the proper gas coverage. The second mistake was that I thought I want getting adequate shielding so I kept turning up the argon flow. I was just making my situation worse. This video fixed everything!
Now I gotta try some stainless!
Thank you, thank you, thank you!
Sometimes it's just one little thing you gotta correct to make it all come together.
Man I wish I would’ve seen this video a couple weeks ago. I just started getting hot and heavy into learning tig welding, new 255ext, every pack of tungsten I could order, and all sorts of fancy cups and adapters and accessories, only to learn and try for myself that 80% of it was a pointless purchase 😂. Thank you very much for this video!
I did the same thing when I got my first tig machine. It was the powerpro 205. I almost went with the 255ext, but the powerpro had a 50 amp plasma as well.
Justin pretty much nailed it there. I also bought way too much 1/16 tungsten and fillers that never get used
Learned TIG back 50 years ago, even taught it around 40 years ago, all with the big clunker machines. TFS is a great series of videos, but the Weld Coach series is promising to be even better (both this vid and the AL vid are on point). Justin, you are doing a bang up job educating people (hell, even this old goat learns something from your videos) in the wonderful world of TIG and all its intricacies. Well done!!
Thanks for all your information! I wil try it my net weld session
What is TFS?
@@GlennLaguna The Fabrication Series, another one of Justin’s youtube channels
Needed this video 5 years ago when I first began TIG welding! This answered so many questions I could not find straight answers to anywhere else.
Yes, Finding these Answers is Very difficult normally, it is just not mentioned anywhere. Some Tig cup Companies might give you "Ballpark figures" but not always.
The only other person who said this info was the "weldingtipsandtricks" channel, and it was one random video.
Finally some common sense information regarding cups. Wish that someone would have clued me into this years ago before wasting time and resources and finally coming to the same conclusion. At least now those new to tig watching this will be spared the trouble of finding out the inevitable.
Thank you sir!
For stick out I usually just put the tungsten tip into a corner at a 45 degree angle and try to eyeball a right triangle. This usually gets a good general stick out and provides some level on consistency or you can just do as Justin says and use the proper stick out of what the size of the cup is. He did make a neat little tool that gives you perfect stick out every time but when I want perfect stick out I just use a combination square. Works like a charm.
Thank you for sharing your experience.
Thank you everyone for the kind comments and support. I'll try to answer welding questions here if @weldcoachofficial doesn't get to them first.
Lot of useful information in this video. Thanks for putting it out there.
Great show, and very useful advice, thank you.
Great new channel Justin. This is the information I needed to get me started on tig welding.
Good luck on all your projects 👍
Thanks Justin......short and sweet .....absolutely brilliant....!!!!
You just explained in 5 seconds of this video what took me hours to figure out the hard way... only to forget and have to learn it again. Awesome content and best of luck in all of your ventures!
Always great content and well presented...Thanks Justin!🏁
Save your money on crappy consumables and use that cash in booking a class with Justin. Not affiliated, just saying, this guy's been here forever teaching us for free, literally tolerating folks thinking he's an AH that doen't want people to progress because he's so blunt and honest he says it like it is. I thought he was BS us and lost months before I listened to the guy and it literally made the difference. Want to get better? Get good tungsten in 3/32", your favorite color, sharpen 10 or 20 units (you'll dip them twice per bead when you're starting) and a std #5, and use the money you'd blow on fancy things on metal coupons and practice kits, a good hood and gloves and classes. And never think you're above the daily practice time. Thanks Justin! You're the real thing man.
Two important facts I needed to know and you gave them to me thank you very much. My welder still hasn't arrived but I needed that information. Thank you very much.
My stick out for all cups is touch the cup on the table, lean it over 45*, push the tungsten to the table, tighten the cap. Season to taste.
I enjoy your simplified approach.
I appreciate the new channel. Thanks for the information as I’m starting this new hobby.
Thanks for clearing this up for me. This answers a lot of questions and saves me a ton of time and money in all these areas. Thanks again Justin
I'm really enjoying this channel, thank you, Justin
I am excited about this channel and your new website, looking forward to learning and getting proficient
FYI Justin this video showed up in my feed without me searching it out. I watched your previous one about how you were concerned you tube was not pushing it. Good vid thanks for the tips. Just another garage hack getting it done but I agree cheap consumables are a waste. Good luck on the new channel.
Thanks for confirming!
One of the biggest changes I saw in my welds was not only the cups but the quality of tungsten , switched to ck worldwide and had some of my best welds yet , I’m still perfecting my craft but that was a big help
One off your best, simple and informative videos
Grate
I watched the Fab channel but didn't know about this one. Good info ; now subscribed . Thanks.
Such a good video. Thanks for sharing.
Love these videos thank you so much! Getting my first TIG very soon. I already understand a lot of the more advanced aspects, but these are the fundamentals I'm missing.
Justin, great vid!! Thanks much for the CFH conversion!! I've got a chart on my phone but your way is a LOT simpler!
Very on point. Number 8 universal. Working for me.
Thank you thank you. New Tig welder here and a video that helped me understand cup and flow use.
Heck yeah, thanks man! This was super useful!
Best tip ever, thank you Justin! 😊
Wow! thank you so much. A lot of useful information! I subscribed!
Crazy I bought a #8 gas lense setup 12 hours ago then went to bed and woke up to this video. Great to info to know what you use and that 8 and 12 are “standard” and will cover everything I do, already got a 5 cup on the shelf, I’ve not got into ali welding yet though, a skill I need to learn
Subscribed! Yeah, I’m following you… but it’s in a good way. I thought I had a good grasp on cups, but I learned something new from this video still. Thank you!
thanks Justin. I learnt to weld 45 years ago and I now do some TIG for hobby stuff. I am always learning something new from you.
Thankyou! So simple and I still didn’t know this
Great stuff. I’m a welder and machinist I got access to equipment but am mostly teaching myself. Your videos are extremely helpful.
Great explanation with everything, good flow, easy to understand, & very relatable as to make the information easier to digest. I wish your old tube bending videos were this easy to understand, everybody want to use the term cheater pipe to dam much
Very informative, well done
Keep it up guys, this channel is going to become the go to for beginners!
Im learning a TON from you!!!! Keep it up!
I for one will be enrolling cheers man for all your help.
Great video, thankyou for including litres for us metroids, and explaining how social media affects your cup choice!
Thank you for taking the time to help everyone out with proper stick out and gas flow.
I also agree with you about buying cheap knock offs.
I've learned my lesson, some parts didn't even fit up properly .thanks again...
All the best
Finally someone breaks it down!!! Now I want to learn the size where it screws on and why. Thx Justin!
I'm going to double check my gas flow.
Flashed my eyes 8 months ago from auto darkening helmet.
Real tears and pain.
See a eye Doctor right away for numbing drops because waiting a week won't help.
Always been impressed by your way of teaching.
Thanks.
I've done the same with a snap on Auto darkening helmet.
I feel like it's so hard to trust any auto darkening hood now.
Justin, Have you worked on refurbishing the R2D2 stick welder you got hold of a handful of years ago? I believe it was an ancient Lincoln..
Old time welder here back when gas welding/brazing was taught in freshman year of school in shop class. Enjoyed the tips on gas cups. I had forgotten those guidelines way back in vocational welding school.
Subscribed today 👍
So grateful for this channel. This is giving me the organized classroom detailed information about tig welding I have been searching for. I wanted explanations about what settings do, how to use, why the different sizes matter on cups, etc. This channel nailed my frustrations down. The information is out there, just not organized in a sensible fashion. Thank you from a 100% DV (USAF).
Appreciate the time you take away from cars for welding instruction. This is one of the things I wanted to research before I ordered my primeweld 225.
Thanks! PERFECT info for the newbie. (me)
Info on gas lens vs standard would be good too.
Thank you for the information
YEP - another tight tutorial. Thank you Justin.
Love seeing you back man. We missed you.
thank you for this one, helped me a lot :-)
Thank you, I have been learning to TIG weld for about a year now and find it difficult to choose the consumables.
This explanation of the cups is just the ticket for me.
I have a Vevor 160 amp welder with the switch on the torch and find it good, but adjustment is very binary you could say. I'm sure I will be learning a lot more on this new channel.
My main use for this is stainless steel and possibly mild steel, so I don't have AC capability at present.
I hope you will cover stainless steel at some point as my welds are very hit and miss at the moment.
Again thank you for the information you provide.
I've got a 20 torch now for the last 6 months, and my #5 is the only thing for aluminum unless I want some more stick out and then it's the #8 gas lens . I have a ck #10 for gas lens and can't get nearly as good on steel (it sucks) . I just use the #8 or FUPA for steel or stainless . But for titanium (which I haven't done yet) I do have a BBW . A good share of what I learned was from you . Thanks Justin .
Almost always used the gas lens, but did mainly steel, I had to reach over coring (die cast dies), down into what would ribbing on the part, and it was a challenge to get the flow rate and length of hang out right. But I've had the tungsten way out there, it depends on the shielding offered by the surrounding tall environment and directional control.
Another quality video, thanks
Hi from the UK.
Best video ever. Now I understand. I just had delivered my Amazon mega kit....
and I will bin it tomorrow and buy the 2 Furic cups that I really need! Thanks so much for a no fancy talk explanation. Nigel
Great video ,really useful .
happy 4th of July to you Justin, cheers from Paulie Brown in Orlando
Great video thank you brother.
Thank you Justin.
Newish to welding. Really new to thinner merals.
I was blowing holes in 1.2mm firewall.
Using no8 gas lense but argon was 15lt.
Dropped it to 8lt and increased preflow to 1sec which allowed the surge of gas to settle before the arc started.
Welds are much better with no holes.
Thanks again
Great info to share
thanks coach 2 excellent tips i didn't know ,yup time to subscribe
Great information 😊
Great video man!
This is a great vid for a newer welder like me. Watched your other vid on the casting and I was beating my head against the wall like you can came to the same conclusion, it was just solidified after I watched your vid. I was also making these mistakes during my casting repair process. The casting I was working on was 1” by 1” and not ornamental.
Thank you!!! The flow rate rule is something I did not know. And the -6 cut for aluminum is also something I will be trying. I have been using a 3/4 cup with diffuser and the welds look okay but now I know why my arc was so crazy!!! I have watched TFS for a long time and just subscribed to Weld Coach.
How were the results?
Fantastic video 👍👍
Great vid thanks!
👍 thanks for sharing! Just found your channel and subscribed.
New channel! Come on! You and ole Jody taught me how to weld, oh and the 3 amigos from that other channel I’m no longer subbed to. Think you know who I’m talking about, lol. Don’t know if it got any better but I dropped out the first video when they were gone.
I tig welded for the first time with, moderate success today, with an extremely old Miller welder. I was having a lot of problems with the tungsten breaking and contaminating my welds, but now I suspect it was caused by way too much gas. So thank you for the information on the gas rule.
Thanks Great tip
Thank you 🙏
Best I have heard explained
Just checking in on the new channel. Subscribed and activated
Wish I lived closer I'd love to rake one one of the classes I sure could use it
Gas flow, and you answered my question, so thanks coach
I'm welding stainless and I do prefer the #8 and the Jazzy 10 from Furick. Especially for thin material of 1 or 2 mm.
For the algorithm, plus thanks for the awesome videos. Also makes me wonder why my DC only Esab came shipped with a nr 6 cup, if that's more alooominum size.
good video. only thing i would add is the 5 standard (or stubby) works on aluminum with less gas than a 5 gas lens. for me i use the jazzy 10 on stainless because gas here is expensive and it still works well on lower gas rates. also if your working on dirty crap which blows crap everywhere, use a standard or cheap replaceable gas lens like ck gas saver. otherwise it gets expensive replacing gas lens.
That explains an issue I had. With the wide puddle. Lol. I dId order 4 cups from furick but I wish I had seen this first. I got 5 6 7 and 8. So not all bad. Thanks man.
Great video
Thanks
Cheers Justin
I wish I had seen this video 4 years ago when I bought a Pyrex cup set with green o-rings. What a waste! Thanks for the good informative videos 🤙
Excellent
You probably already have this in the "pipeline", but a video on setting up the gas would be welcome. Top, center, or bottom of the ball is my biggest question, but I know that is a general setting that needs to be tweaked based on how your machine and torch passes the gas through to the cup. Also how to tell if you don't have enough gas (close but not enough) and maybe too much gas.
For reference I have Primeweld 225 with the junk pedal but the CK torch (need to buy a good pedal!!!) And a flow meter from a youtube competitor that seems like a big step up from the one included with my welder.
Flow is measured from the center of the ball since the ball sits loosely in a tube, and the highest resistance to flow would be around the side or middle of the ball. However, the gas flow is set in a "window" which means you could measure at top or bottom and probably be just fine based on the scale of the meter.
I picked up one of those flow meters for checking the flow at your torch, mainly since I wanted to be sure my regulators all read the same so I didn't have to know differences for each. checked it against the 4 regulators I have and all seem to read around the same. For example if it shows 15 cfh at regulator I'd see approx 14 on the flow meter on the torch fairly consistently.
Seems simple enough..... BUT, excellent advice for the beginner !!!
I prefer the glass cups. It brightens up the welding area.
I was hoping that you would go into cup sizes in reference to cup walking /pipe tube diameter. I was working for a place for 3 years doing food grade stainless tubing for breweries. We only had number 10 cups... it was always rushed.. I never got realy training... so I would freehand in. One day I tried to do the cup walk /wiggle on some 1 inch tube and a another welder from another company just walling by said the cups too big.. I'm a confident welder. Lol but I'm overthrowing it. I'd love a video on the technique and cup size for nofill tube welds. Some say wiggle some say walk it. I. Not with this company anymore at the moment so i can't practice but some guidance for next time would be great
