There’s a lot of advantages for some of us that started gas welding.
Good to see you back Trev.
Absolutely good to see you Trev!
good to see you please find another rusty project to work on i love to see metal working pro jects thank you
Great to see you back Trev. Again, a top video with oodles of excellent explanation and tips for the restorer.
So nice to see you and receive some of your knowledge! You make some of the best videos within topics like this! Thanks for spending your time on this and sharing with us!
Great to see you Trev! As a professional welder who also does restoration work, I love that you put this video together. I have always used this -
*Structural/strength (Frames, etc) = wire weld (mig)
*body/artistic/patches = tig or oxy/acetylene
*coach building = oxy/acetylene"
Great information Trevor! Good to see you back. 😍 Cheers mate!
I started with stick welding and a very simpel transformer based welder.
More more more trev … thanks for your time and help
Good vid and lots of good points.. On the car restoration front, another point for the MIG welder is it's tolerance to dirty material.. Of course perfectly clean is best for any welding, but a MIG will get the job done without complaining much about some rust pits, while it'll be an absolute nightmare to TIG weld through it
Hello Trev. Thanks for this roundup, it's very relevant to me, I'm welding up a very rusty 100E. Old Cebora 130 analogue. I'm not doing too bad, and your tips will help. Good luck with the business and thanks for the content. Mart from Mart's Garage.
Glad to see you Trev....top notch video.
hi Trev good to see , you say mig gives you a hard bead which i get, but thought you said in one of your vids you could use mig wire to tig weld, doesn't that make that weld bean hard as well, thanks sam
Thanks for the question, answer video to follow 👍
No Way. Nice one Trev. You are badly missed. I learned stick welding at college in a broad based engineering apprenticeship.
Mig was a game changer for me with car bodywork. I bought a migatronic pulse tig welder 15 years ago. It sure makes pretty welds.
Absolutely the best welding overview video I've seen! Thanks so much for taking the time to make this Trev!
Good to see you again Trev, hope you and yours are OK and doing well. Very informative video, we are all looking forward to the new content in your new workshop. Take care mate.
Very good piece. I'm still rocking a Butters MIG but I will get myself a TIG for steel for restoration stuff. Welcome back by the way! :)
love this Trev! when I began my journey in custom paint years ago. I find doing my own prep work is key to a long lasting job. As always mate you have done the community a solid for the video,Thank You!!
Thank you Trev. Great treatment of this topic, as per usual. Good to hear from you and to learn that you, your business, and your projects are well. Looking forward to your next offering.
Excellent explanation Trev...have so missed your content here in South Africa.
Always an interesting comparison
Great to see you back and good luck with your new shop.
Very helpful & interesting video thanks Trev.
Welcome back, I really enjoy all of your videos😅
I know you from somewhere I can't quite place you
I've watched a bunch of videos about welding and nobody has explained MIG vs TIG as clearly and concisely as you have in this video. Thank you.
Thank You Trev excellent video Its so nice to have someone to explain things in such a manner that is easily understood
Please don't stop the videos I'm sure you are missed by all your followers
really good content and so informative
Take care
Glad to hear you again... Great content...thanks 👍
Definitely on my watch later list 👍
So good to have the tutorship!!
It’ll be winter here soon and I’ll be back in the shop again. The topic is perfect. I’ll be cutting a Willys Wagon down to an extended cab pickup this winter
A new Trev's Blog, no way! Good to see you! Awesome video!
welcome back trev also great to see your videos
Great video mate, 1 new subscriber
Trevor I got a Cobra Torch !! Oxy/Acetylene made for aircraft welding!! Aluminum and steel sheet metal its fantastic for auto, bikes and things as such!! Don
I only recently joined the modern world. I've been Oxy-fuel and resistance welding for 40 years. In the last two bought a big Tig machine, transformer Mig machine and portable SMAW power supply.
Gas welding Al was too much. Tig is so much easier for that. I use Mig primarily for rust repair. After all, a grinder and paint makes me the welder I 'aint.
🌟Excellent info Trev. (Might get an inverter mig welder, I have a boggo SnapOn 130 now, bought new in 1992😆).
Thanks for your perspective, Trev. I too learned to gas weld first. It was long ago enough that mig and tig weren't considered much. With the then new HSLA metals, we all had to get mig welders. As I've gotten more into fabrication and coachbuilding, tig is the thing. I also appreciate your product info. I'll be trying Corrolan. I love the welding helmet you told us about. Looking forward to your new shop. Thanks again.
Good video, but like pretty much all of these types of video, seems to suggest that things like MIG and TIG welding, are simply a matter of buying the required gear?
Great video, can you do a video on MIG vs YAK, MIG vs SU, love to see how MIG stack up against alternative option
Iv discovered that you have to allways have a gap between your metal because when you start welding the gap closes slightly and if you dont have a gap the metal has nowhere to go so it warps and I allways keep an airline with a blower to hand to blow cold air on the metal to prevent it from warping. And iv discovered your wire thickness is important 0.6 mm works best on car bodywork because it takes less power to melt it and causes less distortion.
Thanks Trev! There's always something to learn from your videos 😎🤘
A new workshop sounds very exciting!
Everything explained so well! Loved the video!
Great advice. Thanks Trev.......its a new TIG for me!
I absolutely love how detailed an explanation while entertaining to watch you're gifting us with here.
I’ve been told if you mig weld you’ll see it on a hot day when the panel expands.
I agree, I agree, I agree. I made the mistake of buying a tig machine to fix my rusty car. It's the wrong machine. You might of mentioned that tig welding anywhere other than a bench is nearly impossible. I tig welded 12 ' of rocker panel laying on the floor with a foot pedal between my knees. I stuck the tungsten twenty times and that means regrinding. I had to borrow a mig machine to do most of the unreachable spots and build the inner structure. Even to tig weld it is helpful to have a mig to tack things together. Another thing to mention is that you need two hands to tig and only one for mig. You can hold something up and mig it in place very, very easily.
Great video Trev. I'm pretty good at TIG on my bench, both thick aluminum, steel, and test sheet steel coupons. However, I just can't see to get the hang of TIG on the car. With autobody TIG, it just sputters, sprays junk on the tungsten, and ruins tungsten. I tried to make sure both sides are clean.
I can relate to your issues. I must confess that my experience with welding on aluminium cars is quite limited. I’ve had varying degrees of success. There is of course different types of aluminium and these all seem to have their own characteristics. Also how old the car is also creates challenges with corrosion buried inside the fabric of the aluminium. Newer Ferraris are made of the most brittle aluminium which behaves very differently to hand built cars. A guy I once spoke to swears by heating the weld area with oxygen acetylene to burn out impurities before tig welding. Cheers Trev
Great material, lots of valuable information. The only thing I would like to hear and what is missing on the Internet is information about TIG welding using CuSi3 rod. It is possible? Is it possible to obtain such an electric arc temperature to solder and not weld body elements?
ruclips.net/video/96j89_HiVac/видео.htmlsi=k-doLfnqIv60Qbs8
Yup, Waxoyl is far too waxy and not oily enough these days. I feel that it better many years ago??
I got a load of 4 inch square steel plates and applied different mixes of waxoyl to half of each. They sat for a few years and it was clear to see that the standard waxoyl didn't really creep at all and kind of dried up and could easily be flaked off. The most effective mix (tried several different oils and greases in several different ratios) was a 50:50 mix (hot) with cheap 15/40 engine oil. This gives a decent amount of creep to fill scratches etc, but isn't too soft and 'wet', though I'd far rather get mucky working on something, than have it rust.
I'm sure that this ratio would be different in different climates. I'm in Scotland, so cold and wet....
You can also mix Waxoyl with normal black underseal which makes a waxy coating very similar to Dinitrol black 4941 when sprayed with shutz gun 👍
Another GREAT and informative video, Trev! Okay...here's my question for the next video.
I'm pretty new to Tig Welding. Now, I've heard a lot of different opinions on Filler Rod. Some say you don't even need it. Others say that it is a must. Does it depend on what you're working on? Or is it more of a choice, rather than a necessity?
Looking forward to the next video! Much love to you, Tracy and your family. ❤
Thanks for your question Jack. Much love to you x
Trev do you think the new confangled laser welders would work on modern car body’s?
I know my new Audi 6 speed gear selector forks are laser welded… tinniest welds you’ve ever seen.
Thanks for all your great efforts.
Love your work
🇦🇺🤜🏼🤛🏼😎🍀🍀🍀
Thanks for the question, yes they’re being used certainly in vehicle body manufacturing 👍
Howdy! Well pleased Trev rock on!
Have you/ would you consider meeting up with one of your subscribers- i.e. someone one you have not previously met in person.
I've been a fan of your channel since I first stumbled on it.
I live in the states and just returned from the UK yesterday. It was a spur- of- the moment trip. Toward the end of it I remembered that I had wanted to try to look you up whilst in the UK. Unfortunately, I didn't have time on this trip
So, on my next trip (perhaps in 2024).
1) is that something you would be open to?
2) how would one contact you?
Regardless, keep up the great work!!!
My email address is in the video description 👍
Excellent welding tips video Sir! I have a question that I never seen in other restoration of welding videos. My question is, what type of gas to use on the mig or tig welders? What's the difference in using different types of welding gas? Next question, When using gas, at what rate of gas usage is used on, well let's say auto body panel restoration? Next question, when a welder is used in conjunction with gas, what size tank should be used? Large? Medium? Small? I am a complete novice to car restoration. I've arc welded long time ago, but this technique doesn't ever be mentioned. Yes, I know an arc welder will blow holes through regular sheet metal. But what of cracks, or splicing in a frame piece? Thank you once again Sir! You're truly a professional teacher!
I’ve actually covered most of what you’ve asked in my mig and tig welding tips videos here’s a link to the mig one you can find the others in my other videos Mig welding set up Part 1 Volts/power and wire speed Tips and Tricks #45
ruclips.net/video/kLFpcZruetI/видео.html
Fantastic knowledge with great information given on mig /tig welding in such a short amount of time,
Never thought about modern cars using strengthened steel and replacing damaged wing with mild steel,how that would effect the weld.
You also gave a in site to the type of weld in coach work, interesting,
As only been using stick welder AC for home projects and are limited with this, its time to get out my 4 in 1 new welder going,
There`s a huge amount to learn with welding so many professional welders have so much info to give, but weird how they can have different methods, many way to skin a cat as the expression goes, `
Even using the wrong mix of gas could over strengthen a weld, witch can make it stronger in hardness but brittle and will crack further down the line,
Its a fascinating profession to go into and dangerous toxic wise , especially galvanized and stainless steel when breathing in there fumes,
I hope in your next video you could find the time to talk on the safety aspect about the dangers welding with certain metals when heated, Not many professional welders speak on this subject, its important to newbies to know this,
But got to mention you came across very professional in explaining the pit falls with the two types of welding,
I think its could be a life time learning curb as Technics change with materials,
Thank you 😊
Trev, where is the workshop that you work at? I have just bought a VW Phaeton with aluminium doorskins. It has small areas bubbling and I need them repaired my someone who knows his eggs.
Hello Paul I’m sorry but I no longer work there. Their contact number is 01285821887 ask for Steve 👍
Learnt heaps. Loved the ending.
This is fantastic- thank you!!!
How he said to save the panet🤣🤣 @20:33
where have you been..welcome back
Always love your videos!
Thanks, great information.
Quite the do!
Hi Trev do you need to spend a lot on a welder or do the cheap ones still do the job? don't laugh at me but are the Lidl ones any good as they seem good value for money
Answer coming 👍
This is why I have both, but I started with mig.
I missed the Hair!
Glad your back trev 👍👍👍
Great tuitional advise , thankyou
Can you "heat shrink" a tig weld?
If you had a TIG welded joint across a panel and you needed to shrink the area the weld was across, then yes this is perfectly possible 👍
Trev just do it
Thanks Trev!
Mate, sheep have nothing to do with it. It's all about the rust inhibiting chemicals. Any oil or whatever is just a carrier. Oil in itself is also not a rust inhibitor but also just a transport medium. I do generally agree with the welding tips though. With the exception of your example of structural welding. Penetration is everything there and it should never just be a weld bead on the surface.
Sheep have 100% to do with it, lanolin when applied to steel hermetically seals steel from oxygen and moisture, you don’t need to add rust inhibitors when you can naturally provide them.
Lanolin comes from sheep.
What was the outro music that ended the video?

TREV!! Missed you, buddy! Hope you're all keeping well. The Viva is now a 4.6 V8! Cossie engine was going to cost too much to rebuild, so all that stuff got sold off! Cheers. Leigh.
very simple explanation. question is, i have a 140 transmig gassless mig, why or what is the purpose of being able to change the polarity of the earth cable as i have always been of the understanding that on a mig the clamp is earth and the torch is positive. cheers
Ok good question 👍 flux core is supposed to be positive earth, mig using gas negative earth 👍
@@trevsblog great. ill have to check mine. i presume its + earth as its been gassless straight out the box. good timing, as i have a gas bottle i havent got around to connecting yet as no need for the welder yet. i would have just connected it and used as it was. cheers
@@steveandsara7240 yes mate just change the earth to negative, don’t forget to change the torch side! Usually located by the wire feed 👍
I'm 65. My dad was a perfectionist panel beater. Oxy Acet only.( that's all they had) I was taught how to oxy weld thin aluminium at 12 years old. SO I'm biased. Oxy/acet is my preference. Tig is very like oxy acet. You can work the metal. MIG was developed to weld structural steel..pump the amps in and fill the joint. My ignorant attitude sees MIG as a lot of "hard" tacks that make the weld brittle. A whole lot of grinding and you end up with a crack worthy joint that is most likely thinner than the parent metal. Thank you for the expalnation. I understand that the new auto steels are not the same as the old stuff and might accept the new mig tack method but as everything is rush and dollars now I suppose MIG is the go. Time spent grinding it flat is questionable. Rant over. I love your perfectionist work. Very inspiring. Thank you.
Nice one Trev, I've always said that you should learn to weld with Gas first (oxyacetylene), when you can do that, start to learn to Mig (not that silly flux core metal welding shit with no gas, simply horrible stuff), and then progress to Tig, that I still think is the hardest of them all. keep it up Trev, and good luck with the new/revised workshop.
Good thing I bought a mig to work on my tractor and mower-deck then, though learned on gas at art-school - forty years ago mind!! Been following Pete Williams too as I have replacement motorbike tank to make (thanks ethanol!) - prolly use the spool-gun that came with the mig, if I choose to go with aluminium - more learning ahead for this ole geezer!
Thanks for your vids mate, always inspirational, if not always quite attainable!
This video was really informative. I have done a bit of mig welding (1936 Austin 7 Ruby and 1972 Wolseley 18/85 Landcrab). Certainly not to professional standard. But I still own the Austin, and after 25 years she is still pretty solid.
Now I understand what TIG welding is all about. I also have some idea of how you were able to get such an incredible finish on the panels you fabricated for the Bedford. Thank you very much.
❤🖖👊
Good Video. For those interested. You can buy a 3 in 1 Inverter welder, Mig, Tig, Stick. I replaced my transformer type Mig Welder when it died. You spend more time setting up the welder to get a good weld than actual welding. I replaced it with a Kempi Evo Miniarc 200A. Welds Mild Steel, Aluminium , Stainless Steel and Bronze weld for low distortion on car panels on presets on the welder. Just go up a size in the gun tip size for aluminium to avoid jamming the Aluminium Wire in the Torch. Run parallel welds for welds in steel over 5mm Thick. You can TIG weld up to 1.6mm Mild Steel edge on edge without filler wire and is as strong as the parent metal. You can TIG weld any metal with the appropriate filler rod. 30 years ago I did a 60 hour welding course for $60. Invaluable. The instructor made the class weld 10mm plate, V beveled, to show us why you use TIG for sheet metal and MIG for above 3mm. The Metal was so hot it lit the room. Making parallel runs to fill the bevel. I have all 4 types of welders. I mainly use MIG because a monkey can MIG weld or somebody out of practice, which is the same thing.
Good grief you know your stuff Trev, explained a lot to me.I don't do much welding these days (I'm 78) but my 1970 Morris Traveller is still doing OK after my welding efforts many years ago. Thanks for sharing and best regards from Ireland.
Definitely agree regarding transformer vs inverter MIGs, I brought one of those cheap transformer welders with only four power levels, managed to weld up a majority of a rusty Transit, but boy, was getting an inverter a much nicer experience after all that pain 🤣
Top video. You hit the point. The only point of criticism, this shouldn't be "tips and tricks #65".
It should be the first video of "The basics of car body repairing, resauration and coachbuilding".
We missed you, and I am sure, because of you are managing personal and business issues in a quite difficult ballance. Please keep going and keep in mind: "Finished job is better than the perfect-one". We love your approach and we are asking your more videos. Köszönöm
wow! You you just blew the fog out of my head about this stuff, all the while, while just speaking to the camera, Super great delivery. I am getting ready to remove and replace the back section of my rusted roof rain gutter section of my van with a perfectly good section I clipped out of a wrecked vehicle. I have a welding pro guy with me but I want to do this job.... I've done a fair amount of DIY welding in the past, but your video pushed me over the edge.... I'm gonna set up, Jig up and go for it. You know how to speak to people like us! Thanks and definitely subscribed from USA.
Great to see you back Trev!! Great vid and very informativ. Thanks for sharing!!😊😊 Gus🇳🇴
Yayyyy your back Trev, good to see and hear you again. As always an excellent video with brilliant explanation by your good self. Dont be a stranger Trev we miss you too much.👍
Thank you Trev! Useful video even for someone with a bit of body restoration experience) Waiting for more videos!
Very informative, can you do a video on mig brazing with Cusi3 wire on cars? I think this would be very informative and helpful as there is not that much info on this subject, this is another process and it would help me and other people in this industry, i think mig brazing or even tig brazing is very interesting subject that should be more talked so that we can learn it more.Thanks for informative videos, cheers.
Hi Trev. Tremendous video and great advice. I do want to weld aluminium in the future so like you I will buy an analogue ac/dc tig welder. I also found my mig welder is an inverter type and as you say its great out the box but difficult to know the changes to make to make it perfect. Still your brilliant as is your wifes channel great work.
I'm so glad your back!! Thanks again trev. Very informative as always
nice video, next you can do a tutorial how to fix/repair/replace bodywork studs (the ones used to screw fasteners to secure under-trays, shields, brackets etc, not the stud-dent pullers) without having to buy a dedicated stud welder for couple grand..
Great request thanks 👍
@@trevsblog It would be awesome. There are lots of videos in regards to dent pullers, but very few related to stud welding, and none actually sharing some workarounds that could be done by us DIYers on personal projects who happen to have just a stick/mig/mag welders. I have seen one of the old videos you had made explaining about the studs you did, but you re-adapted your stud welder for that too. Any insights in this regards without an actual stud welder would make a great video imo 👍
@@antanasrapkevicius3897 well just a hint towards would be to drill a hole in the panel just big enough to fit a stud into then weld the end of the stud onto the panel from the inside. I’ve also made a simple square plate welded the stud again through a hole in the plate and then bonded the plate to the underside with panel bond, this prevents you from burning the paint off the boot floor and the surface area of the plate allows enough strength to the panel bond to hold it firmly in place 👍
@@trevsblog thanks for the tips 👍 I have no access to weld from the top unfortunately due to cavity areas, but I can actually make small round/square sheet patches done with the studs this way and then weld in said patches to the bodywork. This might work for me. Appreciate the help
Excellent video 👍👍👍👍
I’ve missed your videos and I hope to see more soon 🙏
Wow very informative. Welcome back into my head. 😅. First experience was gas welding quite liked it found it easy. Stick or arc welding even thin stuff. I do have and use a mig welder sometimes as I no long have bottles. Quite fancy a tig just to have a go.
Cheers Austin
Brilliant Video Trev, looking forward to seeing the new workshop and more videos!! 👌👌
Very good explanation Trev. Not a great welder myself but manage to get buy with a cheapo welder. Best advice J can give is to turn the machine on and burn some holes/melt some steel and fiddle with your knobs til it starts to work out.
Good to see some new welding/bodywork content from you Trev. I enjoyed all the videos on your Bedford. Hope to drop by for coffee and a cake someday.
How about that I’m a newb looking for my first welder ! Brilliant vid Trev thanks mate I know what to buy now 👌👍
Good to see content again Trev. So my question you can answer later concerns direction. Does it matter really if you push your weld bead with the torch or you trail it? Pushing the weld bead seems to work well for me, but it does create a fair lump to smooth out again. Loving your work from Sydney 🇦🇺 .
Nice to see you again Trev. You are the absolut best to explain processes by breaking them down.
The clips used in this one, made me want to look back at your older videos. Looking forward to see new videos, when you finish up you building more space. All the best👍
