Thanks Jody, I went today and bought a diamond wheel $ 10.00 from Harbor Freight a 6 inch grinder some filler rods came home married the diamond wheel to the grinder got some tungsten purple from Air Gas tried out my grinder works great Now after watching your video I understand the grind angles now after 50 years of stick welding I am going to try TIG I was good at gas welding and it looks similar. It looks fun to old to make a career out of it just want to run some beads anyway enough said thanks for showing old timer new stuff.
hey jody, i am a welding student from rotterdam (NL) and i really want to say thanks for making these videos. it has been really helpful to me especially the tig welding videos. by watching and applying some tips it gave me a diffrent view on welding. Greetings from holland! Daniël
Jodi, you sir are an excellent teacher. Your arch shots have been the best on TH-cam for a long time but they are getting to be ridiculously awesome. Thanks for taking the time and sharing your skills with us.
I know you made a very comfortable living working in the aerospace industry but you missed your calling for sure. If I would have had teachers like you in college and high school I would have been a 4.0 student! Brother you have the most informative and captivating educational videos I've ever had the pleasure to view. I'm a 40yr old Maintenance Mechanic at Century Aluminum Smelter of Hawesville KY and I'm definitely learning more from your videos than any class or training the company has sent me to. Keep doing what you do because we love your stuff and thanks for the knowledge it's the best I've ever seen!
I love watching these shows where the demonstrator has equipment that I will never be able to afford. Started with things the Yankee Workshop was able to produce before I started noticing the planers, lathes, miter sets, and biscuit cutters. Now I look at all the settings my little Tig welder doesn't have.
I'm in my 40s, recently retired from the army, and just started a welding class as part of my major. I've been watching your videos as sort of a means of getting a leg up on class. As of this posting, we haven't touched a welder yet, but after watching all these, I am anxious.
Sir, I just came across your amazing channel. Your gift for teaching and delivering instructional material is matched only by your humble attitude. Thank you for being the exception on youTube, Look forward to binge watching your channel and all upcoming videos.
Although posted 7 years ago, still spot on! Many thanks for sharing and your pleasant way of presenting and yes, only people searching for this information willbe looking at your video's 🙃
You are a wealth of information and a jewel on the Internet. I really want to learn how to tig weld on my everlast welder so I'm learning everything from scratch.
Excellent video. Thanks Jody. Just getting to grips with TIG and what a voyage of discovery it is! Got my first job as a welder making refuse skips with a 450 amp MIG. Back tracking to stick just to make sure I can stick metal together now. TIG is still something I have yet to get flowing right. Never been a gas welder so in at the deep end it seems. Prep is everything. My main piece of advice to anyone learning to weld would be keep your mask clean! And no back light behind you. Get the light source out in front and you can really see the weld. These vids are so good as you can really see what is happening. Great work.
This is a great video for students to see. I suggest that instructors show this one on their overheads while doing their theory class. Thanks for sharing.
2:01, you really haven't even started yet, and yet I just learned something of what I've seen and had the effect of with my minor Tig experience. Nobody I was working with told me that the sideways grinding of the tungsten would mess up the output like that, but that's exactly what I was working with ... All I had was a table grinder without any guide like you have there, but had I known I certainly would have made the effort to hold the tungsten in a manner to grind it lengthwise.
I use an odd tool for sharpening but it works REAL well. Take an old belt sander, put on 80 grit belt (or finer), turn the whole thing upside down, turn it on, lock the 'on' button switch, and center the belt tracking, put the tungsten in a drill chuck (I use 20V lithium ion DeWalt), set that on low speed, use the tail case of the sander as the guide, and wipe the tungsten across the belt w/ very slow turning speed. This grinds the point metal AWAY from the tip, does not leave swirl marks, and it's real quick to do. : )'
He really is! I sometimes see welding videos where they just show a bright light and a bunch of sparks, and you can't see anything, and it makes me frustrated. Jody's videos are helping me to go that last mile. You can have everything in position and set up right, but what is it supposed to look like? I now think vision is the hardest part, constantly fooling around with different glasses and filters and cheaters to see what we see here on the screen. Sometimes it works!
глубина провара, заточка --понятно .хоть бы слово понять... Недавно стал просматривать ваш канал . Ваше отношение к присадке ,расплаву понятны мной давно . Многим не нравилось моё отношение . Спасибо за видео канал .С уважением Влад
Hey Jodi, the halo is, where temperature forces the electrones out of the tungsten. the cooler - the later in the taper they come out. And they leave rectangular to the surface. br Bernt
I'm going to be steepening up my grinds now. an additional benefit of this is that when I've ground my tungstens to the fine taper, as they get contaminated and I regrind 'em, they heat up too hot and too quickly/get used up quickly!! Thanks Jody, this'll save me time and money too. : )'
Interesting. I never thought electrode shape affected penetration. Also, the wandering arc was an eye opener. If I was still in the trade I would definitely look into using a finer grinding wheel. I remember holding the electrode so that the grinding lines were parallel with the center rather than across. This usually resulted in grooves in our wheels, but cut down on arc wandering. I wonder if the penetration difference is a result of more electrical resistance at the tip of the sharper electrode.
I have really enjoyed and learned plenty from your videos. I watched em all over the years, funny though, I never even owned a welding machine.... Now that I bought one, I'm learning even more the second time through. Thanks Jody.
Really interesting to see effect of tungsten grind angle. Basically you can weld ok with any angle almost !! except the very small/pointed grind angle is best for welding thin material. Thank you for wonderful demo. Mike
@weldingtipsandtricks God bless you Jody I've been watching you since I was in community college about 5 years ago, your videos helped me get my first welding job and I still watch you to this day. Hands down best welding channel on the internet if I woulda known about this channel out of high school I woulda bought a multiprocess machine and got the Same education that I did at community college.
Jody, Another excellent video, as usual. These demo's are perfect for people still learning (like me). I do use that middle size angle most of the time unless i'm welding Alluminium.
Love those Piranha grinders! The 3's are awesome but due to cost I'd go with the 2 for home use. Great video. The cut and polish was super cool to see and the arc shots were great too.
Thanks Jody, I'm a newbie and have been grinding my tungsten like the second example. I'll have to give the other types a try as well. interesting to see the differences in penetration.
Big thanks for making this vid when you did. I'm not sure if I requested this topic or if I was thinking of doing so, but the info comes exactly when I needed it. Thanks again
So I was checking into a Welding Engineer program then I got to thinkin', I can just watch Jody's videos and save myself a whole lotta money. Great Video and lovin my Tig Finger.
Love this video, a lot of my own questions were answered, I have not been to school for welding but trained on site and have been taught bad information and techniques. Everyone there grinds sideways and to a very long point
Now I can see why I have the the problem where the arc wonders, what would be the best grit for grinding wheel? Mine is too rough and it does wonder like in the video. Thank you for the videos.
Jody thank you for what you do, once again. I could have watched this video before starting the night shift yesterday I'm 100 percent positive I would have been better. now I have more knowledge just cause you enjoy doing this.
that was really impressively sciency with all the strict controls on the variables from the angles to the gap and weld speed. very nice test, good info. Did wonder if the IR measurement of temperature pointing at the shiny metal surface really made the measurement of the metal or the reflected room temperature. Emissivity and all that.
I'm right there with you on that second grind. CK has some information on dimension vs penetration. Max is 3 times the diameter of your tungsten according to their information. I like 2/3 of the diameter and the tungsten really settles in cleanly on long runs of aluminum. Just the best in my book too.
book says that cone length should be 3 times the diameter o electrode ... looking more like the needle sharp.but as i see now better blunt than sharp, thank Mr Jody , have a happy 2017.
I am nothing like you. You are an expert teacher/welder and I can barely stick 2 pieces of metal together! :) Very good comparison, interesting results for sure... thanks for the video Jody
....watch, go practice what you've seen, repeat! Had opportunity to learn to weld myself starting with just running 6013 in position beads in H.S. shop back in 1975/76. Much practice, some work related experience since. Got to be an instructor to adult and H.S. students here local to where I now live....not welding!, ( instrumentation, core, and construction management.) I regularly used TH-cam videos as an integral part of the C. Mgmt. H.S. classes (plus much lab time/hands on) and that's how we discovered Jody's neat site, products, and videos!! Great stuff, several of my students came back for 2 to 3 more semesters, several got 6G tig and stick pipe certified and a couple now earn more than I do!! : )'
Excellent video,but i thing that you could have better results and no secondary energy jump point with the third (super pointed) tungsten if you use helium or argon/helium mix instead of pure argon.
Hi, Judy. I just order your TIG finger and Strong hand mag tab from you. I want to support your channel because I've been learning many things from your knowledge and your welding experiences. Thanks again for your dedication, Welding. /// Detroit Dark Welder.
I'm curious about the effect of a double-bevel grind, like many knives use to achieve a low angle profile without an overly thin weak edge. The extreme of multi-bevel being a convex grind, and the two extremes of convex being a half circle on the strength oriented end and a simple flat grind on the thin/sharp end. The extreme of a double bevel electrode would be a flatted tip, I suppose. For an electrode I would think the transition between the two bevels would be somewhat important, in degree of change, position from the point, and finish(rounded, buffed smooth, or hard and sharp). You would probably want the position of the bevel transition either fully clear of the plasma or right down in it[flatted tip eg.], but not too near edge/transition of the plasma cone especially if it is a hard chine.
Something I'd like to see demonstrated is old school technique using the side of the ''arc flame''. Yes, flame, just like a Oxy/Acet flame welding technique. Back in the day, most small bore was gas welded. Doing so you used the side of the welding flame ''cone''. TIG arc flame is similar in that you have a arc ''cone'' from the tungsten. Angle of tungsten grind greatly effects that, as well. I'll await your reply. Jeff
great shoot Jodi, is it possible to the same tests for aluminium if you haven't already. I don't seem to have an issue with DC arcs or welding, but AC is a whole new bucket of problems.... thanks
Really nicely controlled experiment. Up to now, I have always MIG welded--Bam! Metal stuck together! However, as a beginning hobby TIG welder, I don't see much distinction between these welds. They appear different by a few hundred thousands in width and penetration. Is the intent of TIG to be that precise or does this experiment show how things might extrapolate in the 'production' TIG process?
I guess the very sharp edge of the third electrode had such a high temperature (=and ohm resistance) that it explains the arc coming from a few milimeters above the tip. I believe the heat was not that concentrated and that is the reason why the third bead was narrower.
Hey Jody, great channel, always my first stop for welding tips! I have a question which I hope isn't as stupid as it sounds! Can you TIG sheet lead? We used to have a great guy who would make lots of lead items, mostly for the building trade. He used lots of blocks as much for support as chilling. Just wondered if TIG could be used as a modern method instead of gas.... Regards Gary
A Master consulting another Master..... the world can be a great place at times ! Gary, hope the hand is well. Great question too. Jody, thanks for all the vids ! Ditto to Gary's comment, I've been welding for 30 years but figured it's time I become a REAL welder so I just purchased a TIG rig (Lincoln 175 squarewave) and have been learning from you ever since. 1st stop.
It can definitely be done, both ac and dc apparently, courses were available here in the uk at one point, but I would love to see a video or any info if anyone has it!
I’ve known about you for a long time. I’ve seen a few videos. My thoughts were always “meh, hes no TOT”. I finally bought a tig welder…. It’s like night and day! The same stuff has completely changed into useful and engaging science! I feel like i should apologize for discounting your videos earlier. I’m sorry sir. I will now be binging your back log trying to figure out why i can’t weld 90s in 1/16 aluminum. Thank you
It would appear the sharper electrode presents higher flow resistance, hence the second arc up higher - what Jody calls a 'halo'. I would guess that reducing the amperage would reduce the second arc/harmonic.
great video Jody. I usually always needle sharpen my tungsten when welding ferrous metals for no reason at all except I felt comfortable with it. now I see that I can possibly weld better with a blunt tip. I wonder what the effects are when using A/C current and welding aluminum??? thanks for the lesson.
on the acute-angled electrode, you said there was a halo effect. To me, it looked like plasma discharge which would explain the low penetration in the metal as electrical energy was being wasted in the plasma discharge instead of being a focused arc. But that is just my observation.
Great vid. I weld 16ga 304 2b stainless all day, no filler, and am always interested in what can get me the tightest arc with the most heat focused on a pinpoint area. 'Always looking to get good penetration without a wide puddle.
That halo is trippy. My theory is it might be creating a vacuum and pushing away the argon from so much heat or pulling in small amount of oxygen. Retest it with different variables of argon flow for that needle one.
Great video and interesting info. when I was learning TIG in welding school and doing open groove joints I found it easier for me to run my root with a needle sharp tungsten. That might have had something to do with what you showed here. Good stuff.
TOT sent me over here. First video I've watched. Very well demonstrated, and I'm looking forward to my binge watching. Thanks!
From a welder of 18 years, these videos are excellent.
Thank you.
Thanks Jody, I went today and bought a diamond wheel $ 10.00 from Harbor Freight a 6 inch grinder some filler rods came home married the diamond wheel to the grinder got some tungsten purple from Air Gas tried out my grinder works great
Now after watching your video I understand the grind angles now
after 50 years of stick welding I am going to try TIG I was good at gas welding and it looks similar.
It looks fun to old to make a career out of it just want to run some beads anyway enough said thanks for showing old timer new stuff.
english 6g welder here sayin this is the best welding channel on youtube, respect and thank you.

Jody is into Primeweld tigs as of late. About 1/4 the price of the expensive brands and absolutely capable of the same results.
I think this is one of your best videos to date. Not very different what you normally do but the compare and contrast was perfect. Thank you again!

Thank you for sharing your knowledge and wisdom. You prove the old adage: If you want to keep what you have you must give it away.
So much to learn from your channel each and every video. I often need to try what I've watched with my powertig to let it all soak in.

I loved how scientifically you controlled the variables
Need video !!! Have to start calling you the king of arc shots.
So true. Looked a few older vids from 2012ish and he's really up'd his game since then, great videos. His hair looks better now too!

this guy really gives great information and explanations, much thanks
Beautifully done video ! All meat, no filler. Thanks Jody !
awesome. I've always used the needle sharp tungsten, I may try the more blunt grind and see how it works for me.
My favorite welding videos on TH-cam, great knowledge. Thank you sir!
Excellent detail and analysis. The comparative images are masterful. Thank you for your willingness to share with us all.

PS: I learned a lot from this, as usual from Jodie's Videos'
Super cool, precise & concise! I'm going to play around with a blunt grind, never tried it (still learning). Thanks for the video!
I have no idea how to tig weld but your videos make me feel like I could👍

AMAZING video Jody, thanks!! I guess it's time to revisit some blunt'er tungsten angles.
best videos ,have learned more from you in short time then in three years school/practice...the best thing is the glass head...greetings from germany
Great video! Thanks for visualizing and explaining the welding processes and for sharing your insights.
That tungsten grinder is badass!
just ordered a basic Stubby kit! can't wait to give it a try, thanks for the content. 🤘
I assume this also holds true that the bigger the electrode the greater the heat input to the part?
Excellent video, keep playing scientist! Fascinating stuff.Do you ship supplies to canada?
Thanks, and yes I do ship to Canada
Very informative video. I will have to try this next time I fire up my everlast.
Excellent video,but i thing that you could have better results and no secondary energy jump point with the third (super pointed) tungsten if you use helium or argon/helium mix instead of pure argon.

Jody, thanks for all the vids ! Ditto to Gary's comment, I've been welding for 30 years but figured it's time I become a REAL welder so I just purchased a TIG rig (Lincoln 175 squarewave) and have been learning from you ever since. 1st stop.
It can definitely be done, both ac and dc apparently, courses were available here in the uk at one point, but I would love to see a video or any info if anyone has it!
Sounds interesting, and DANGEROUS. Perhaps if-- provided ALL LEAD FUMES are safely filtered/ventilated elsewhere.
nice video jody I like to see stuff broken down like this so you can see the results
I’ve known about you for a long time. I’ve seen a few videos. My thoughts were always “meh, hes no TOT”. I finally bought a tig welder…. It’s like night and day! The same stuff has completely changed into useful and engaging science! I feel like i should apologize for discounting your videos earlier. I’m sorry sir. I will now be binging your back log trying to figure out why i can’t weld 90s in 1/16 aluminum. Thank you
It would appear the sharper electrode presents higher flow resistance, hence the second arc up higher - what Jody calls a 'halo'. I would guess that reducing the amperage would reduce the second arc/harmonic.
Great video. Thanks for sharing. Looks like the secret is that tungsten grinder.
hey Jodi nice video! can u do more videos on distortion please? thanks
great video Jody. I usually always needle sharpen my tungsten when welding ferrous metals for no reason at all except I felt comfortable with it. now I see that I can possibly weld better with a blunt tip. I wonder what the effects are when using A/C current and welding aluminum??? thanks for the lesson.
on the acute-angled electrode, you said there was a halo effect. To me, it looked like plasma discharge which would explain the low penetration in the metal as electrical energy was being wasted in the plasma discharge instead of being a focused arc.
But that is just my observation.
Great vid. I weld 16ga 304 2b stainless all day, no filler, and am always interested in what can get me the tightest arc with the most heat focused on a pinpoint area. 'Always looking to get good penetration without a wide puddle.
Where can I buy a tungsten grinder like yours with the adjustable angle holder?
I really enjoy all of your videos, I definitely have learned quite a bit!! Thank you
That halo is trippy. My theory is it might be creating a vacuum and pushing away the argon from so much heat or pulling in small amount of oxygen. Retest it with different variables of argon flow for that needle one.
Sooo much good information in this video that I need to practice with my everlast welder. Good stuff Jody.
Great video and interesting info. when I was learning TIG in welding school and doing open groove joints I found it easier for me to run my root with a needle sharp tungsten. That might have had something to do with what you showed here.
Good stuff.
great video... what machine do you use to sharpen tungsten like that again??
