Dipping the tip , ahh, I remember those days
I'm no TIG expert but I have just recently done a TIG course at the Men's Shed, so I can offer you a few tips I learned during that 6 week course.
First tip is get some TIG gloves. Get some of those tighter fitting soft leather gloves. You don't need the same kind of protection that you need for MIG, so you can trade protection for a bit more sensitivity (I use them now for MIG welding, even if I have to replace them more often).
Second tip (which you obviously learned online, which I didn't know) is that for TIG and gas MIG you push into the job, for gassless MIG you drag. You need to be able to see your puddle which is half the reason you want to push, also you want to be shielding the metal as you melt it not afterwards.
Third tip surface prep is everything, especially when doing alloy. The mild steel you are doing is in between stainless and alloy in terms of how hard it is to flow the puddle.
Fourth tip tack your ends. I know you were only doing practice welds, but bad habits are formed by not doing the right thing. You could do fillerless tack on both ends before you started your run. Then blend the tacks into the main weld.
Fifth tip, your filler wire angle is too high. You want to get it as low as you can. Try maintain a 90 degree angle between the torch tip and the filler wire. You want the filler wire to almost be touching the surface of the thing you are welding (even if it feels a bit weird). I like to hold the filler rod a bit further back, especially when doing alloy because at times you are going to need to feed it in faster than you can move your filler rod through your fingers. Experts can do it, but it probably takes years of practice to make it look easy.
The hole was because you stayed in the same spot for too long / you didn't cool the work piece before you tried to join the third piece of metal. This is one that has caught me out a couple of times especially doing alloy. You want a spray bottle or a container to dip your parts in so they can't get rid of the heat. The first weld you did the parts were much cooler, but by the time you added the next piece they already had heat soak in them. Which combined with staying there a tiny bit too long is the difference between a hole and no hole.
I blew plenty of holes during the course in various materials and I learned a fairly effective way of repairing them. When trying to fill a hole point the tungsten away from the hole so the heat is on the thicker material not the thin melted edge otherwise you will just make the hole bigger. Next feed in plenty of filler, probably twice (or more) faster than if you were doing the ideal weld. You need material there to stop the hole getting bigger so sometimes that requires a really fast feed. The great thing about TIG is that you can smooth that lump out later.
Don't be tempted to keep going and going in the same spot. When trying to fix the hole, the temptation is there to think I nearly have it fixed, so you keep going and going over the same spot. Try doing this with alloy and the difference between everything looking great, and a massive blob of ally dropping away from the area takes about 1 second. Move to another area / cool the part before trying again. You will be surprised how quickly you can overheat the area.
Turning the power down was a big mistake and you can see that in the weld. I understand why you did it, thinking less heat is less blowout, but the issue was not the amps it was the technique, see how the welds went to shit. It lumped up straight away because it was too cold.
Sixth tip watch where you are putting your torch down, several time you put down the torch allowing the tungsten to come in contact with unprepared metal. Make yourself a simple torch stand so it doesn't touch the metal and contaminate the tip.
Finally your repair attempt. I knew you were going to blow a hole in that the moment you showed us the hole. Not because it wasn't repairable, but because you didn't have enough practice to attempt such a difficult repair. That was probably 10x harder than what you did on your makeshift welding table.
Seventh tip ( you learned the hard way) check list. Make sure your gas is turned on and the earth clamp in on with a good ground. Might seem obvious, but I have done it several times, coming back from a break you forget to turn the bottle back on or forget you disconnected the earth when you went to cool the part.
OK so let's look at your repair attempt in detail. So why would I say I knew you were going to blow a hole the moment I saw it? Because it was the perfect storm. A lack of experience combined with a very difficult repair. The moment you tried to swap hands I thought he's stuffed it. You had no where near enough practice to attempted that let alone left handed which you had zero experience at doing.
On the bench you had two pieces of metal 1.6mm thick butted together. Even with that "thick" metal you blew a hole. This was the first contributing factor you should have practiced and practiced till you felt super confident going in. I also knew you would attempt to weld it with lower amps than you had been practicing. It is the natural response for a novice (been there done that myself), even if it wasn't the right one. But the biggest thing you had going against you was not your skill level, but the fact that you are a MIG welder not a TIG welder. So if we were trying to patch a pin prick hole with a MIG we would point the wire at the hole and give it a quick tack.
I will better dollars to donuts you did the same thing instinctively with the TIG. The combination of the already slightly thinner roof metal, combined with it rusting way thinner, that was the guaranteed outcome. Couple that with the fact that you couldn't get the cup in close because of the drain channel, further added to the storm. You needed to up the gas flow and stick the tungsten out further so it was the right distance from the hole. Then start the arc away from the hole (yes very different to MIG) and start feeding in the filler wire like there is no tomorrow. Then later try smooth it out.
Being that it would be so damn hard to grind in there, the natural instinct would be to try and do a MIG type repair on it with minimal weld. Would I have blown a hole in it? More than likely yes, because I would have been tempted and probably do the things I am telling you not to do. That was a bloody hard repair even for an expert. You would need to be able to join sub 1mm material like a metal coke can to be able to do that repair. That was an advanced level repair, which more than likely didn't have enough prep.
Overall I think your welding efforts with the TIG for a first go were not half bad, I would go as far as saying pretty decent, but they aren't up to the level you need for that kind of repair. Also as a side note, you would have been far better off cutting some tiny bits of filler rod, laying them in the channel and trying to melt them into the hole, trying to melt the filler rod rather than putting the heat into the paper thin body.
I agree with your approach to fix it, make a patch piece, tack it in the corners first, and DON'T attempt to weld it like you did on the bench. Just stitch it, let it cool, stitch some more let it cool. Take plenty of time and don't just try to rip a bead of weld in like you might with a MIG. All in all a good effort, just a pity about the outcome. That wasn't a bad effort even with the outcome. It was just a learning experience.
Wow, thanks for that.
Scotty, you're trying which is a lot more than some folk. I'm not a welder & I've used TIG, not very well but I have mates who are welders, so I let them do the work for liquid currency. I spent the better part yesterday doing the suspension in my VY S LS1 Ute swapping it from FE2 to FE1. Everyone has told me to leave it alone as it sits good on FE2 but I'm restoring the ute back to how it came from the factory. Yep, cars are a pain in the ass, but remember, doing it yourself as much as possible leads to better & prouder results. I admire people who give it a go when they've not done it before.
“Old dog new tricks “ keep at it mate, teaching myself the past couple months also and it will fall into place naturally. Matter of time on it.
Don't take this the wrong way but I laughed pretty hard when you burnt your hand on the roof, brightens up every Monday at work when I can sneak in an episode of Scottys Garage so keep up the good work.
@@paulelston6733 I laughed too when I edited it
It's Great to see you are having a go. But
The roof. The roof. The roof is on fire. And it's hot.
I'm only 10 minutes in to watching, and have to comment. THANK YOU for doing this Scotty. I have wanted to try welding for so long, and again you've inspired. EVERYONE has to start somewhere, no one is instantly good at something, and to share your beginnings publicly is massive. also a shoutout to the comments section, from what I can see so far, has been completely supportive, rather than critical. This is a great community you've built. ... Now I'm off to buy welding gear..
@@DaveHiggoHiggins thanks mate
Scotty mate even before I watch the video, Im nearly 30 and completed a mechanic apprenticeship recently, I feel like if you take on something different and can work with your hands you can actually succeed in teaching yourself from your mistakes and eventually perfect your skill level.
at least you're having a go at it. you're doing a better job than anyone that hasn't attempted it
how good is this learning in a real world scenario, ricketty arse wobbly table in a garage and improvising on a work area. No gloss over on this and showing the learning process and explaining what you are trying to achieve on being self taught 👍🤘
Hi Scotty I always found TIG the hardest. I had to learn and pass it 30 odd years ago for my Engine Reconditioning qualification. Not sure I could do it anymore. In fact I find all welding hard as I have an unsteady hand. Anyway have a good week and thanks for the. Marc
Hey Scotty, Jake here from supermangs water to air tank. you're definitely on the right track, 2T no foot pedal, low amps, torch angle/rake should be anything from straight to 15 degrees (85 degrees). you can also push and pull if you're using the torch wiithout filler. The most important thing is to get comfortable and have fun! if you would ever like to collaborate again i'd be happy to spend a few days with ya. Cheers Scotty, all the best.
I lost your details, dude. Send me a message
Hi Scotty, I've also tried leaning to Tig welding with little success however a few things I've learned are
1/ When you were practising Tig welding, you had your test piece sitting on a metal table , the metal table draws the heat away making it much harder to blow holes , so when you tried welding the car it's "far" easier to blow holes .
2/ When filing a rust hole the rust behind the hole is usually far larger than the hole itself so the metals much thiner around the hole.
3/ The most important thing to do is, practice, practice, practice before touching your car
Only way to learn Scotty.
I went to trade school for 3 years and they didn’t teach me anything I didn’t already know.
Everything I learned was on the job…
It's all good mate, doing good. Just be aware posting a welding video on YT brings out many, many experts. Many with less experience than yourself, even some with none. They still know everything.
@@bunning63 Yep, I'm expecting a flood of comments, but that's okay if they're watching
Brave man doing this on u toob, 35+ years and I still make small mistakes. Practice makes perfect.
Practice practice practice. You’ll get the hang of it mate
Thanks for taking one for the team Scotty and apologies for spitting my weetbix out and laughing at 24:30
Idiot sandwich 😂😂 thanks for the laugh mate. Well done giving it a crack too. Something I've been meaning to learn for a long time.
Awesome Scotty,, only way to learn from is your own mistakes an trusty words from your mates.. keep doing whatever you're doing..👊😎..
Yay! Patch time! Youll get there mate. 👍
That wasn't to bad an effort for a beginner, you'll get a handle on it mate. 'Soldier On'. 👍.
Someone can have all the training and watch all the videos in the world on welding which does help a lot, but it all comes down to practice and experience of actually welding to become a more consistent and confident welder.
It's a learning experience thats for sure. You did better than me at my first and only attempt. I threw the toys out of the cot and went straight back to the mig. I really take my hat off to those that can tig reasonably and even more to those that can tig works of art.
Gotta start somewhere
Good attempt Scotty, stick with it. The roof metal is probably 0.9mm. Get some thinner sheet to practice and just tack it.
I just brought a similar looking machine unimig Tig 200 Gunna do the same and teach myself how Tig. Luckily some of my friends are amazing Tig welders. Unfortunately I'm a fitter and I weld like a fitter to lol. but only one way to learn. look forward to sitting down and watching the whole video after work.
Oh and Scotty just so you know bud your definitely an inspiration to many mate. Myself included your carnage videos inspired me to get out in the shed and buid cars again. Your have a crack at anything attitude is fantastic and refreshing to see. Keep up the great content.
@@jamiemarshall6295 LOL, at the fitter comment
@@blownhemi finally got home and watched the video mate. I would love to see you keep trying with the Tig bud as I tell the apprentices at work. A man who never made a mistake never made anything. Keep at it. I'm sure when I try it I'll be worse but they still make steel.👍👍💪💪
@@jamiemarshall6295 they sure do
As a welder, I'm a really good truck driver 😅. It's a skill I haven't caught up on since arc welding at TAFE during my apprenticeship. I as well need to do some rust holes on my VS Clubby. Need that practice time before I commit.
As someone who grew up learning by myself to oxy weld, stick weld, mig weld and know enough about each to make me dangerous. I havent had the nuggets to try tig welding yet but it is something I want to learn, thanks for making a start on this and making me laugh along the way. Keep posting your progress, I'll be learning from your experiences 😁👍
If you can oxy weld, tig will be easier to learn.
My Skid factory stubby holder is all worn out and the bottoms gone,time for a new one from Scottys Garage this time...
Your welding table is an active part of the process. It sucks out the heat and provides a backing for the weld poo. On my car i blew three all over the place until I bought a piece of 50mm copper pipe and found some old 12mm copper pipe. If you place the flattened copper pipe BEHIND the welding gap you can weld more easily. The copper sucks the heat out and the weld does not stick to the copper, so you can use the copper as a backing for the welding pool. Car panels are thin...
Great work Scotty, the best way to learn is to have a go.
Welldone Scotty✌
I'm transitioning from MIG to TIG too, so this video was very interesting! 👍
Re the holes in the thin metal, I think MIG with a fine wire 0.6mm or 0.7mm is a great method, just do lots of short tacks (less than a second) on the edges of any hole and it quickly fills in.
MIG is great for that because it literally stuffs the wire right in its face.
I recently did a toolbox with 0.7mm thick sheet metal (ouch) and it was hole city, but I was able to tack up all the holes easily enough.
@wizrom3046 Yeah, I agree MIG is better for this
Nice work scotty 1 thing i have always wanted to learn is welding 👍
scotty sometimes a block of copper underneath can help stop blowouts on thin metal / hole filling
Just touched over midnight and this edit caught me by surprise at 22:45 and coincidentally watched his uncut show briefly before coming to Scottys channel
Ditch the mig gloves and get some tig gloves you will be able to feel the wire. Riggers gloves also work well.
I used to spend hours with no wire and just practice running it. Then I would just practice feeding the wire thru my fingers. Try both hands LH torch, RH wire. RH Torch LH Wire and just settle on what feels natural.
Good work Scotty! Love the honesty.
I too am an amateur Tig welder, although several years at it working on the odd project. In the early days I also learned quickly that welding two pieces of near new metal together I’d very different to welding steel on a 30+ year old car.
Keep it at though! You will get there and in time find it becomes relatively easy.
Keep at it scotty practice makes perfect 👌
Awesome and honest
I have the exact same TIG! The most important thing with TIG’ing is cleanliness. Get yourself some acetone and a dedicated rag. Also, get some bigger cups, I found that helps. I use my mostly for aluminium though.
Nice work Scott, i have same welder, i watched Trevs blog for Tig tips i was struggling to fill holes as well and his tip was arc on the filler wire not the panel to stop the hole blowing bigger and you cant fill holes in one go it takes a few times of fill a bit, stop, let panel cool down, fill a bit more to fill holes same as it would with mig
Thanks for the tip
Having tig gloves will help
@@MultiHotrodman I've got to admit, I didn't know such a thing existed until recently
Thanks Scotty….. makes me feel a little bit better about my bird nest mig melds not to mention my tin can with more holes than an afgan…. Keen to tig tho, they say u should use a pro’s set up get a base line
Awesome video Scotty. Just keep practising.
Keep it up.
You can’t become good at something if you don’t try. Keep it up mate, maybe a course would be good but as you said finding time might be hard
You need to put copper or aluminium plate behind the holes your trying to fill.
Doing the same with my Lincoln 200m I have the same wand that you have and hate it so I bought a foot pedal it seems easier so far I need much more time yet great video mate
Great first crack Scotty! Definitely get yourself a pair of riggers gloves. You can also set the tig to start via the button which is find easier and i found the pulse setting easier to weld with. Keep in mind i’m self taught with 5 mins tuition from a boiley. Also keep a wire brush handy post weld to clean up the heat marks 👌
Well, if it wasn't you then it would be me lol! I have been thinking of upgrading from the gasless mig, which has been great in doing small rust patch repairs but always need a good clean up. Maybe I will look up some local courses first!
Id use mig for filling holes. I haven't used tig for body work yet just stainless steel work. But for patch panels using tig should be easier. 👍
22:44 you got me crying here 😂 love it
Yeah, it made me laugh too
Chin up mate
Hey Scotty your doing great on the tig mate for a first crack at it , I found when I used to tig it was easier to move the filler wire if I had a riggers glove on that hand for more movement on my fingers and still use the welding glove on the other , maybe give that a go for next time 👍🏽
@@Matt_685 thanks the advice
@@Matt_685 thanks the advice
We’ve all been there mate. You never know unless you have a crack.
Hey scotty tried putting some thin copper behind anywhere where you’re trying to do a pinhole repair or while your first learning to but some of this together it will act like a chill bar but also will stop the blow through. Cheers
I know people that used copper plumbing pip cut and flattened perfectly other have sued scrap buzz bar offcuts to put behind the thin metal to patch pin holes
Cheers
Any metallic mass will work, but I don't think that was an option in this case.
I’d love to be a metal master….you see them dudes make a 1/4 panel outta flat steel…..blows my mind!!!
They're pretty amazing
@@blownhemiI’ve also never welded…I’d love to give it a crack.
@michaelteasdale2919 creating stuff is fun. Welders can be had cheap, check out next week's video when I buy a MIG for $50
@@blownhemi$50?
Stop it!!!
Don't be so hard on yourself mate !
Laugh at those who criticise but don't have a go themselves.
Just a little hint mate.
Get a firm table to weld on !
I noticed the plate moving and obviously putting you off.
Cheers big fella from Penrith yet again.
Your having a crack Scotty that's what matters. Practice makes perfect ,👍
Steady hands
I also shopped at the unstable table shop for my welding table
Do a au falcon
Stick with it !!. Practice make perfect, Not sure about in VIc but in NSW in 90s 1 night a week TAFE welding courses. Ditch those gloves ( their MIG ones = need thin leather welding gloves), Some ( even cut off finger tips of the weld rod feed hand for better control ). Use foot control = can vary current while welding = that weld towards the end = everything got too hot and not enough pace = foot control = can back off amps !!!
Tig is all good in theory- however I think Mig on low setting is better for hole filling, short burst followed by a blast of air to keep cool, keep up the good work.
That would have been a tough repair with a MIG. The problem is the metal is paper thin. You can't get a rust hole without it rusting to zero thickness, so the edges are going to be very thin. You might have been able to braise it, but that was 99% always going to be a patch repair.
25 years as a boilermaker and i have never TIG welded, so i can't knock ya for trying. I would say like all welding practice practice practice makes perfect. Anyway just wanted to say you can MIG body work, just need the amps down and travel fast. The biggest mistake people make with sheet is going too slow as once heat soaked it's game over. From what i see on your TIG welds i would say too hot but more a travel speed issue over amps. General rule of thumb i would teach apprentices, is your weld thickness shouldn't exceed your largest material thickness. So 1.6 gauge the weld should be around 1.6mm wide
Thanks for the advice
Thanks so much for this episode Scotty, you did exactly what many of us would do when learning. It's an exercise in practice. Maybe if the @HackShop boys are near you, they can come on the next episode and lend a hand and share some tips?
From what i know, if you hold it like an airbrush its easier . Ive tried it once but thats what i was told to do, if not maybe get a foot pedal set up??? Not sure really not going to make it out like i do know 😂
Also, get something to place under your TIG arm/wrist to stable the tourch and what setting you have that is allowing the burn to run on after releasing the button, turn it off, when you let go of the button the tig should stop.
I get why he stuffed that up. I have done that myself. When you MIG weld you are used to hearing it just stop. The whole letting go of the button and hold it there for a few seconds is extremely foreign, and when you are nervous to begin with it is easy to forget you need to let go of the button and to just hold the torch.
I think finally, I maybe getting a job after sometime being in a rual area a new face and in this town, it's not what you know, it's who you know and your not local unless your born here or been here 30yrs so after 6 yrs, im pretty sure I have it well I hope so it was very casual interview telling me the truck is just getting some repairs and I'll get a call im sure wasn't BS seeing the truck had its tipper raised and rear guards off..I hope so then I can do more to support, I want Dads ute and lockdown wagon shirts because during covid I was in a real bad time in my head space being out here and no one would even look at me ..those videos and vehicles were my get away, and mean something to me...welding 😂😂 I honestly no bugger all I had a crack at stick welding and just laid bogies so yeah that is way out my league 😅

@@blownhemi 😂
Finally got around to buying some merch, but unlike Scotty, I’m not brave enough to attempt tig welding. Oxy is where i belong 😂
@honestpat7789 thanks for the support, mate
Oopsie!!! I'm no TiG welder but I do know that the amps for 1.6mm steel will be far too high for 0.8mm thick bodywork steel. Then you have rust on the underside of the steel and you have to adjust the amps to compensate for the poorer conduction.
Still, I think that was a brilliant first effort and unlike MiG welding TiG is practice practice practice
TIG Gloves Scotty, I can send you some if you want. And try a size 8 cup and a gas lens. Go and talk to KO Welding
Also, rest your torch arm on something, or you're gunnna be in some pain after a few minutes
@@blakamin I'm only just learning these things existed
Chicken wings blahlallalalah hahahaha
Wrong gloves Scotty, TIG gloves are thinner and have more feel.
Nothing wrong with old dogs and new tricks.
😊
Hey Scotty, keep practicing mate. TIG is king at showing you how crap you are at TIG. Ask me how I know 😂. Been trying for years making little things for my cars , some successfully, some a miserable failure.
Thanks mate, I'll stick with it.
Just clean that sheet up and practice running beads first.
Could be worse Scotty, like when you stop welding to look at your greatness but the helmet is still dark because you set everything on fire! Not that I have done that...
You cant weld up rust holes like that in that manner even if you are a skilled welder scotty so dont fret! I rekon there is alot of pitting on the rear of the panel causing it to be paper thin. You need to really cut out atleast 1" into the panel whenever you have wired through on the body and replace it with new metal. If its paper thin doesnt matter your skill really but you probably need to get that foot pedal out for that kind of of work so u can modulate the power as you watch the panel start to fall away. You also need to hold your hand steady by steadying your hand on on a surface, you were attempting what tig welders refer to as freestyling and thats not a novice move (Your cant maintain a consistant travel speed, angle, and contact tip distance without one.). You didnt do yourself any favours by re-welding over the same spots. You really should be only tacing every 1" around the butt to stop the panel from warping. You stack tacs till you make it the whole way around, then grind and repeat. Im using flux core to patch up my troopy after learning the cut-n-butt off fitzyz fab, he is a great teacher th-cam.com/video/eKM0Yhgg040/w-d-xo.htmlsi=CrNUqBi_M91nLOr4. Its cheap and does the job although it makes even great panel guys cringe as that recent video shows. Making mistakes with greg has a good intro to tig where i learnt all the above. Honestly i think its very advanced to body work with tig its def not an easy task, making mistakes with greg has some very good intros to the basics i mention above in his recent series: th-cam.com/users/results?search_query=making+mistakes+with+greg+tig
This is why God invented hairy bog (Fibre filler) ................... :-)
Wait till you hit a patch of Lead wipe, THATS fun
Chin up scotty can't learn from your mistakes if you never try in the first place. Practice Practice Practice on the scraps of metal . Ask the guys at mpw for some tips maybe take the tig machine with you get them to properly set up and show technique . I did a short course at tafe they pretty much just go through the basics of the three main welding types it was nearly more written class work than practical .
I've just recently finished a TIG course myself. There is no substitute for practice. All the theory in the world is just that till the rubber meets the ground.
Don't you have to push a tig?
I did mention that
I did mention that after the first weld
@@blownhemi yes I went to early. That's what she said
You CAN'T learn TIG in a couple of hours!!
No, you can't
Sell the TIG welder and buy a MIG. Solved.
Haha, wait until you see what I bought... it's worse
@@blownhemi A Temu special? 🤣😂
😂 nah thanks for sharing your learning m8.
Always good to have a wet rag and a fire extinguisher 🧯 on standby and an observer if possible as things tend to burn 🔥 extremely fast and while welding you aren’t always aware there is a fire 🔥 till it’s a big one 😅
