- Can you weld TIG weld copper with Argon gas?
.
Many welders will tell you to use Helium as a shielding gas, I'm going to test this for you so you don't need to! I'll also show you the equipment I use, what rods and tungsten.

Thank you! You’ve convinced me I can do copper! I currently use argon for aluminum, and I have thoriated tungsten for when I do stainless, and I have a TIG machine that can put out 750 amps if needed! Another video showed I can use copper wire as a filler! If I planned to do copper a lot, I would set up specifically for it. But since I only need to tie a couple of electric buss bars together and they don’t have to look pretty, I’m sure now I can give it a go! THANKS again!!
Practice, practice and practice is the key to welding. One day I am going to get a tig welder and have a go. ESAB stuff is great. I have an old ESAB Bantam TBH 140 and it is a brilliant stick welder. Keep up the good work young lady!
I'm looking to make a copper water tank for a homemade camper. Thanks for the point to start with!
Nice Job 😊
Keep Uploading more videos, it will be beneficial for Viewers
Thanks for the tips, we’ll have a go, going to have a go at an overhead position pipe 🤣 wish me luck!
Good on you sister, for, as we say in Oz, 'having a go' - because if you don't you'll never know. (What d'y'know? I'm a poet but didn't know it.)
Nice to have Sponsors.
I have so much to learn about welding but like you said hands on practice. Fun video :)
Thank you, practise makes perfect! There is so much to learn! :D
Very nice Charis!
Thank you :D
I think the only reason you need to use helium is if your welding thicker copper because the helium essentially ups the heat output. If your single phase 200Amp TIG set is maxed out , using helium it would be the equivalent of 340Amps . Thin sheet metal is so much easier to weld using a foot pedal, saves you relying on your pre set slope down as your workpiece gets hotter as you weld, you can back off your amps as needed as your welding to keep the bead the same width from start to finnish. I'm sure you know this Charis but I thought I would comment just to expand on your great video.
I think I'm in love.... with Tig welding I mean..... Yeah...Tig welding...
Ofcourse you can weld copper with Argon. But we know that Cu distribute heat fast and when you weld you want to heat up the spot you are welding as fast as possible. Its not only to get the job done faster, when you put in too much heat or energy (welding slow on a low amp) it will become harder to weld and the weld will get an ugly look.
Its also somewhat important to make it clean, that piece you welded are full with oxides. The more pure or clean copper the better. There are copper with diffrent purity and it makes a big difference.
When you weld thicker Cu material it can become ridiculous slow so 100% He or a mixture of He/Ar is often to prefer. You get a somewhat better penetration with He but so do a higher amp, better torch angle, torch distance, a pointy electrode, less filling material and so on.
What gas you should use, depends on many things but in your case welding a low quality thin copper piece once argon is definitly to recommend because, its cheaper. Using 100% He would be insane, just turn up the amp!
I get it, the helium has no effect as inert gas, but it has the best heat capacity so it cools the surrounding area. (Same reason Stirling engines run it)
@@teamidris I keeps the arc narrower, so it's more concentrated, penetration is deeper. Been welding copper with argon for ages and before that with Oxyacetylene torch, making copper stills. Welds were always hot hammered - heated to dark red with a torch, then hammered to flatten the seam, after the scale was cleaned with diluted sulfur acid and scrubbed with sand and again cold hammered, to harden the area. Use of cold shoes makes the annealed area much narrower, less than 3/4". The amps must be cranked up and area preheated with the torch before starting laying down the bead. To get nice ends, small rectangles are placed and welded to the main piece, lest they melt. Now I just lightly hammer, then I grind and weld disappears if finely ground or polished, but shows if patina is applied with a slightly different color.
@@panan7777 I still haven’t started so that is very useful info. (I got working on the 1958 landy because it needed some love)
I use strands of heavy electrical cable to tig light materials with lower amps, so typically I would fuse a 1/8” stainless welding rod to 2.5mm weathering steel. These are small wrens that can be planted in the garden and bounce in the breeze. To do these I normally run 40 45 amps. It’s faster and easier than welding and yes I can tig conventional materials.
Most interesting. I just ordered some 3mm plate and I feel I am in with a chance now :o)
teamidris aw, really? That’s awesome! Glad to be of help 😊 Let me know how it goes 😉
@@CharisWilliams Thanks :D One person has said I wont get a cert on it? So i need to check the PED on ickle steam boilers. I don't think there is anything on silver soldering vs tig welding, only that it is made using 'sound engineering practice' and a pressure test. Should be interesting :)
I see that small piece of copper sliding while she is welding it... maybe I'd clamp it down, not sure.... and the other thing I am wondering about: is the speed at which she is progressing with the bead the best? It seems too slow to me. But, I am just a bloody beginner, so correct me if I'm wrong!
Love those Masks, shame they are so expensive :(
Nice job with Argon gas, and i can only imagine the heat coming off that piece :O
The most expensive are you eyes. Damage from being blitzed is cumulative, it adds up with years. So this is the question: are your eyes worth 500$ or less to you? I'm shortly buying one of the best - Optrel Chrystal 2.0 for 400$ tax free here in the EU. You work much faster and your eyes will thank you. I predate this masks and I KNOW what I'm talking about...
How on earth did you get ESAB to sponsor YOU?
Mam who are use you tungsten rod
Gas-
Filler wire-
⁉️
Please tell me.
Did you have to adapt your power at home to accommodate the welder so that you didn’t blow the electricity in your house or your neighbours? We have a welder but the leccy won’t accommodate it 🤔
Reclaimed Life hiya, no, not at all. Haven’t had any problems in that respect. I just got a schuko plug adapter as it had a Euro plug being Swedish. I just plugged it in and off I go. It is a single phase machine, is yours?
Can you weld using dc??
I was surprised to see how thin the copper was. It seems like there would have been much more blowout after being on it for so long. Cooper is difficult to weld because of its property if moving heat. But when you get to the end of it and there's nowhere else for the heat to go, it will give you that quick sizzle right before it blows out.
Why helium as a cover gas for copper? I thought helium was just used for welding overhead...? I've only tig welded copper twice. Both times using argon
My understanding is the helium conducts the energy much better. The figure I've heard is, running helium effectively doubles the amperage of your welder when using argon. So you get much better penetration on steel, and can dump energy into the copper faster than it can conduct away.
@@richardconnor2871 get out! ..really? This blows me away. Thanks for the info. I'm definitely going to be looking into this..
dc tig argon try that
Just need to dye your hair yellow to complete the ESAB sponsorship
Did i learn ? No i didnt learn....i hear all youtubers say that "im gonna set the tigwelder and we can begin welding" ..... but..... nobody is giving any info about the settings.... AC or DC for copper ? can we do both ? which settings with AC and which with DC .....input give us input.....thats how we learn .... teaching and showing off are two completely differenct conccepts....
Cheers
Have a go.
DC for copper.
Charis.... set the machine 20-30 amps higher and feather the foot pedal.... your foot control will come more in time.... Ive welded copper using pure Ar previously and although you are supposed to use pure He, I found little issue but it wasn't for any important feature.... Keep burning kiddo and posting them vids.... Regards
Lol, will do ;) Thank you for the advise, I will try that, love hearing new tips to help me progress. There is so much to learn, but I love it! I'm using a temporary welding bench at the moment that I've cobbled together, when I have more time to set up a proper welding area in my new workshop (which is under construction) I think I'll be able to get much more comfortable and relaxed.
its probably 40 amps per mm, so 5mm is 200 amps?
Shaky torch hand girl nice job with argon
We need more people of your identity in welding. I only know of two: You and my friend Peter but he’s more of a carrot top than a redhead.
Wow, you can you say Stitch Welding? NoT?
I love welding, MIG is my favorite using Argon gas.
What material are you welding with this process?
@@AlabamaTree normally just steel tubing nothing fancy I welded frame rails and other items
@@AlabamaTree I suggest using official welding references when choosing shielding gas and filler. You'll learn more that way. You can MIG non-stainless steel with pure argon but it's not optimal for most work.

"Common gas mixes for the home hobbyist and small fabricator:
100% CO2 -Lowest price, generally greatest penetration, and higher levels of spatter. Limited to short circuit and globular transfer.
75% Argon - 25% CO2 -Higher price, most commonly used by home hobbyist and light fabricator, lower levels of spatter and flatter weld bead than 100% CO2. Limited to short circuit and globular transfer
85% Argon - 15% CO2-Higher price, most commonly used by fabricators, with a good combination of lower spatter levels and excellent penetration for heavier plate applications and with steels that have more mill scale. Can be used in short circuit, globular, pulse and spray transfer
90% Argon - 10% CO2- Higher price, most commonly used by fabricators, with a good combination of lower spatter levels and good penetration for a wide variety of steel plate applications. Can be used in short circuit, globular, pulse and spray transfer"
Most cost-effective for hobby welders is CO2 if you don't mind (or contain) the spatter. Pure CO2 cylinders last longer because CO2 stores as liquid under pressure then sublimes into gas. 75/25 is typical MIG mix stocked at welding suppliers. Pure argon is more expensive besides being less suited for most work.
Probier mit Kupferzusatz auf Edelstahl zu schweißen, dann reden wir weiter
Another big mistake.....elevate weld joint off the cold work surface. The heat will not be sucked out of the joint. Weld AC and balance on full penetration. Helium mixes not needed.
The back of the weld will oxidize if you do that!
@@acewelding no big deal, 2 swipes with wire brush remove anything. Copper 1/2' or more use argon/helium mix, 50/50
u dont see this at all on youtube... NO THUMBS DOWN VOTES.
Jeeezzzz... I managed to hold on for 34 seconds, and then gave up. Is it necessary to have disco music while talking about welding? It's OK to have an otherwise lovely accent, really, but it does not help to get one's ears accustomed to it easily when the darn music is overriding everything. What matters more ? To show that you know how to put on a CD and play music, or to clearly demonstrate what you intend to teach, without any interfering background noise. Well, actually, here it turned into hefty foreground noise! What a pity!
OK, now in a different version: Dear Charis, could you please, do the next one without the disco theme? I really would love to learn something from your videos. It would make them more professional. Thank you for considering it!
A little later, and after trying to go on with it one more time, to see where this is going..... Ahhhh well, thank goodness! The disco theme is off! Heavens be thanked! LOL.... she heard me! Now, that's so much better!
....... silence is golden eh wot?
Use helium for TIG welding copper. Argon will give you a crap weld.
Love the hood. And yes I say thing in a nice way beautiful woman.
I think you should wear skimpy clothes..........might get a bit of a tan tho....
Stupid practice is welding without common sense.... and this is elit team.... my aprentice makes this kinde of jobes better.
70 A is too much for such thin cupper - the cupper is different with steel or aluminium - you had to fill cupper milding point
dc tig argon try that
