People like things to be simple. They want to use the same gas that they TIG weld with in their MIG setup (or the other way around). Lots of people ask if they can use one gas for all their processes and the answer is really no.
There is a reason that certain gasses are recommended for specific applications and processes.
Today we are going to show you what happens if you try to use your 100% Argon bottle to MIG weld Carbon steel.

Thank god you made this video, I was about to use my TiG bottle for my new MiG because I don’t have 75/25 yet. Glad I watched this before trying it.

@chiathach206 3 года назад

I use pure argon on mig wire before. Its work just fine. Not as smooth or pretty but it will work ..

@melgross 2 месяца назад

@@chiathach206no, it doesn’t. Cut the welds apart and you’ll see for yourself.

@davesage9190 7 лет назад

I guess the obvious question (for me) coming out of this video is - since you say you have all the various gas mixes available why don't you SHOW US the difference with the same settings and different gasses. For example you say you get undercut (or something) with pure argon. Show the undercut with pure argon and then switch gasses and show how it is eliminated. You say you don't like the profile of the weld with the pure argon. Then switch gasses and show us how it gets better. Everybody seems to have an opinion. You are in the unique position to show the differences having various gasses and machines at your disposal. Thanks for the videos. I really enjoy them.

@totensiebush 7 лет назад

You need significantly different settings on different gas mixes to get good welds (CO2 vs C25 being the two that I've tried). With the wrong settings it'll come out crappy even with the best equipment.

@davesage9190 7 лет назад

True I guess. But it appears (in his opinion) there were no settings from "typical" to ridiculous that produced a good weld with pure argon. SO was the point of this video to prove that you can't get a good MIG weld with pure argon? Sorry I'm just trying to find a take away here. I'm still learning and I don't even use MIG. Great video's. I'm learning a lot.

@melgross 2 месяца назад

@@davesage9190it’s not just “his opinion”. The welding industry does extensive testing because reall welding is not done at home in the garage where weld don’t matter that much. Welding has been around for over a hundred years and MiG for almost as long. There are always a few people who think they know more than what industry has found to work and not work. They’re wrong.

@TrevorDennis100 3 года назад

Hey, that was really interesting. I used the MIG at my Menz Shed today, and it was connected to argon with no other bottles to switch to. The person who last used it was not there so I went ahead and used it and I got that same tall, thin bead. I have a feeling that when that person is back, he will say that it makes no difference and we might as well make do with the one bottle. We even had a spare bottle of argon! I've been retired 17 years now, and I never counted myself as a great welder (I worked 40 years as a toolmaker at Ford Research & Engineering in the UK), and my near sight is crap and the MIG welder we have is no great shakes, but I know I can still do a lot better than the result using an argon shield gave me today. I'm just glad I used more than enough weld on todays job, so it should hold.

@danfarris135 2 года назад

You solved my problem. Ive got an old telwin mig that I bought 40 years ago to weld quarter panels and floors when restoring cars. It worked great but the gun/ cable wore out and I couldn’t find a replacement till last year. I have a bottle of 75/25 at home but I haven’t used it in about 5 years. I had a project here at work so I bought the old girl in and hooked up to the 100% argon line instead of using my tank. I couldn’t get any decent bead out of it no matter what I tried. I now have that answer thanks to you.

@fisherus 4 года назад

I know this is an older video but, I have been trying different gasses on a older Lincoln 100 that I converted to gas from flux in my early days of welding. Using a C-10 mixture of 90% argon and 10% CO2 running at a #28 flow rate has this machine running better than I ever thought possible. In some occasions I increase the flow rate up to as high as 40 but rarely, as I am also using. 023 and. 025 wire. I now have a small portable unit, that runs on 120V, I can use in a bind off my generator and get decent welds.

@eugenesaburi1757 4 года назад

Thank you for this. I’ve been using 100% argon for AL MIG in a spool gun and tried using it for steel and ran into the same thing you are. I’m going to get a tank of AR75/CO25 tomorrow to finish my steel project. Thank you!!

@joshuastevens2013 2 года назад

How did the project come out with the 75/25?

@eugenesaburi1757 2 года назад

@@joshuastevens2013 Tried with pure argon but beads just were tall and ropey. Played with settings but still not to my satisfaction. They piece I was welding was part of a retail counter with welds visible so this was a no-go. Going to C25 made all the difference... totally worth it for my purposes.

@104littleal6 7 лет назад

I don't think I ever tried straight argon. Now I know I won't. Thanks for the vid.

@billarroo1 5 лет назад

Gettin that sweat in your eyes ain't fun, last year my helper by mistake put 100% argon on the mig, 035, 70s6, I put 2,000 lb helper rubber springs on a 1ton rear end, welded the pads on and said what's wrong ? The bead had a high crown, didn't seam to have good penetration, so I stopped, cut of the pads and stick welded 1/8 inch 7018, then as I cut off the pads it DID have pretty good penetration but that high crown and arc was too smooth fooled me, anyway I played with settings still high crown, I shut it down as I was closing the bottle, Aha!!!, there it was 100% argon !!! GREAT VIDEO BOB.

@kenkapus6373 2 года назад

I explain to my welding classes that CO2 is an arc stabilizer, this demonstration helps to explain that. Thanks.

@gary-powdercoatingspeciali3093 3 года назад

Very educational for a guy who's trying to teach himself. Learned just one more thing that will help me learn without a fight. 90/10 will be my next bottle and we will see if the quality of my beads improve because right now they suck.

@dorsetengineering 7 лет назад

Really interesting test here Bob. We commonly have trimix gases here in the uk for gmaw, we typically get 3 blends, sold based on the thickness you want to weld.

@RandyBoBandy. 7 лет назад

I've always wanted to see what happens if you strike a 7018 on heavy piece of aluminum.

@gunlover1955 5 лет назад

After watching this the answer is yes you can weld mild steel with argon it just may be a little harder or not look as good, but it can be done and if you just want one gas the gas is argon because you can also weld Aluminum with it!

@davormrsic8765 8 месяцев назад

I wwllding with pure argon with high amperage and volts and it welds fine. You just need to get smooth mellting like lava. Not for tickest material.

@adrianayala9753 7 месяцев назад

@davormrsic8765 any tips you got for mig welding with 100% argon would be helpful as all I see online is some what negative videos like this one. I mostly do aluminum tig so I don't usually have a need for 75/25 so if you got any tips for controlling a 100% argon mig weld would be dope

@davormrsic8765 7 месяцев назад

@@adrianayala9753 As I said. 100% argon wellding is for marine A4 stainless steel where you wellding pure inox because of rust. It is for fatt 10+ mm fatt material. I used Mig mag welldings but for thickest mm like 0.4 to 0.1mm is better use tig wellding machine. You get Smoother welds. Because when you wellding with 100% Argon or 90/10 you need high amperage because you need to make weld mellting on material like lava. It needs to be smooth and soft. Not harsh. I dont know how to explain you better.

@melgross 2 месяца назад

I wouldn’t recommend it. Look, you can weld almost anything with any gas, but that doesn’t mean you’ll get a good weld. If you really don t know what a good weld is, then you might think a bad one js a good one.

@leonardpearlman4017 7 лет назад

As an aside, I've tried to buy things like 90Ar-10CO2, Argon 1%O2, others you mentioned there... and local welding supplies had NO IDEA what I was talking about, didn't seem to want to get some in... so that's why I have a bunch of flow meters and try to mix stuff on the spot for labs. I have found that businesses that claim "If we don't have it, we'll get it" don't actually mean that, it's more like "If we don't have it, you don't need it"! SMITH makes these gas-mixing boxes with knobs on the front, you can just dial up a gas mixture... that's what I really want!

@davidquirk8097 3 года назад

Thanks for this. Just bought a new welder and tooled up with pure Argon for the TIG side of the work. Tried MIG today, with pure Argon, and wondered if there was a fault with the welding set because I couldn't get the weld to flatten out. In hindsight I wish I'd used the stick or the TIG for the job. Oh well, I'll just have to grind it back tomorrow and start again.

@sharkrivermachine 7 лет назад

I used to have a small 110 volt home type MIG welder. I had gotten a bottle of pure Argo to try and weld aluminum (big mistake). One day I ran out of Argo Co mix and tried to use the straight Argon bottle. It splattered and popped and otherwise made a mess of the weld. Thanks for the video.

@brianmaas7058 7 лет назад

Pure argon is used for aluminum.

@StreuB1 7 лет назад

Yep, a small 120v mig and argon is a popcorn and rope producer, not a welder. Sometimes these videos are good because it shows people why that cannot understand. Like you said how you learned. Love these types of videos even though it pains Bob to make them lol

@thomastallman5024 4 года назад

Thanks loads Mr Mofit... I started watching to try and improve my stick welding. As i could put metal together , but looks like shite. And as i watched i found i could improve my over all welding in general. Im a repair guy so to speak. I do a little of this and that. And nothing to big or important to care about a bead profile.. Weld , grind and paint....... But after yesterday's repair. I definitely noticed a change in pentration flow and bead profile in my mig welding. And my stick welding is loads beter now.......

I started Argon welding and Flux cored welding today, it’s different from my normal stick welding. But if there’s one thing I like more than stick with Argon and Flux is that, it’s more efficient and looks cleaner when you work with it. I really enjoy doing both a lot, and I’ve only just begun.

Years ago....35 or so....I bought one of the first Miller-Matic 200's....was building a lot of woodstoves/heaters....1/4" and 3/8" HRS and pipe.....spray arc....tried 100% argon...same results as you got here....ended up using 90/2/8 or 90/8/2 Argon, Co2, Oxygen....seems like the 90/8/2 was best for me, ran mostly .035"....some .045" for the spray arc......although there was also 92/8......Argon, C02...they all cost about the same... I had a small one man shop, I ended up with 5-6 different gasses...Oxy, Acet, Argon, C02, 90/8/2 and some helium....

@chadadkins9760 7 лет назад

We use a 90/10 mix and an 80/20 mix with 811N1 .045 wire dual shield flux and the 90/10 is more of a spray 80/20 is for most everything else including overhead. My personal setup preference is 80/20 .045 at 28.2 volts and 490 ipm for vertical and 29.5 volts and 575 ipm for flat to do a 3/16" bead size and 630 to 650 ipm for anything bigger... the 90/10 is more of a flat weld only gas mix. it's awesome for spray transfer but it's so hot it has higher tendencies to give you undercut in the worst places!

@4BoltClevo 4 года назад

Hi Bob, it would be awesome if you did this with some of those other gases. I just do hobby stuff and I had to go for just one gas and it's 2.75% O2, 16% CO2, and the rest Argon. That seems pretty good, but it would be awesome to see the difference between that and say 25/75 etc.

@ericlee7665 Год назад

Thanks for proving this point man. I learned this lesson a long time ago, thinking that my machine was sucky, because it wouldn't flow a good puddle. Ironically I thought that 100% Argon had to be way better than 75/25. Then I ran some .030 on a buddy's junky Harbor Freight machine with 75/25, and it welded rather nice. Hmm..how the heck is this backyard welder out-performing my Miller?? So yeah,...hooked up a bottle of 75/25 to it and what do ya know?....it flows like butter. Thnx again guys, these bits and tips are gold.

@brianmaas7058 7 лет назад

If you were in a pinch and just needed to tack something together straight argon could be used. The use of straight argon as shown in the video does exactly what you just saw....produces poop. The comment you made about oxygen and that others say "oxygen is detrimental to the weld". Well yes it is in large enough amounts. Common shielding gases for mig welding that use a mix with oxygen does not contain high enough levels of oxygen to negatively affect the weld. Typical mig wires such as an S-6 or an S-3 contain enough deoxidizers to compensate for this and more. As long as you have an argon rich environment, 80% or more, you can run in spray. Great video.

@SnakePliscan 7 лет назад

Argon is not a reactive gas like CO2 hence you don't have the dig factor, add just a small amount of CO2 and its a whole new game. I run 80/20 with 0.030" and go from short circuit to spray with just a turn of the dial. 80/20 is a great all around gas for me with wet out and penetration.

@ls2005019227 7 лет назад

Very interesting test, I've always wondered. I have a Millermatic 252 (runs C25) and a Miller Syncrowave 210, which is a multi process (Arc, AC/DC Tig, & spoolgun Mig). While I always use the 252 with C25 for migging steel, I was curious if I could stick a 1# spool in the spoolgun with the pure argon, in a pinch. The results in your video were pretty apparent, but it still begs the question: why does pure argon work well for tigging steel, but migging steel performs better with a CO2 mix? Very interesting, thanks again.

@davidmarquardt2445 7 лет назад

The reason is with TIG your not transferring metal across an arc.

@leonardpearlman4017 7 лет назад

This seems like an advantage of TIG: One gas for all situations! I understand that some oxygen is necessary for MIG (MAG!) welding on ferrous materials. Needs some oxides on the surface for emission? In England they have Argonox1, Argonox2....

@SolarMillUSA 3 года назад

Except TIG is slow deposition rate compared to MIG. (don't get me wrong, I love TIG, but if you're welding a trailer frame I'll be done in half the time or less with MIG)

@nickheywood8758 7 лет назад

brings up a curious point, Helium with MIG, would like to see the result of that!

Helium adds heat and is usually at around the 2% in a mix. A 80/18/2 could be interesting. going vertical it may be a little to fluid.

Newbie here, but I see you turning up the heat to make it lay down, so why do you keep jacking up the wire speed with it? Seems to me if you want it to lay down, more heat and a slower wire speed would come closer to doing it.

@AndySomogyi 3 года назад

I only know TIG, stick and gas, never done mig. But if you need more oxidizer in the weld, what if you just turned the argon gas flow rate way down?

@oldowl4290 Год назад

I arrived here needing to finish up a small project and ran out of C25 but have a tank of argon. Seeing this I have to ask how much welding on a flat sheet of 3/16” with no joint which is sitting directly on top of what is likely a 1/2” sheet of the table.. will greatly affect it like a heatsink and not allow for good penetration unless you really crank up the heat. In other words, I’d like to see this done with the test plate clamped off to the edge of the table to see the setting differences.

@SnakePliscan 7 лет назад

Careful you don't start undercutting the weld bead when you're cooking like that, your welds will look better an be stronger when you're in the sweet spot which is just back of where you're playing now. Are you welding 1/4-3/8 plate, heavy pipe?

@Likkmymiddletoe 7 лет назад

Mostly 3/8 plate, i rarely get undercut with it though it gets close sometimes, theyre not always the prettiest welds thats for sure, when welding that hot how much weaker does it really make your weld?

@SnakePliscan 7 лет назад

Hi I normally weld with gassless wire or pure CO2. I needed to do some aluminium welding so got some pure argon, worked OK. Back to steel now and because cylinder hire is expensive in Oz and I have a cheap supply of CO2 I am going to try mixing the gasses using a 'Y' tube connector just before the connection goes into the back of my MIG. Any thoughts? Also when should you use spray and when should you use short circuit Thanks in advance Ian

Spray on heavy sections in flat and horizontal. Short arc in all positions, bevels, thinner sections.

Can you weld steel with helium/ argon? I don't weld enough to buy another bottle I mainly use argon to work on my aluminum boat and flux core when I need to weld steel. It would be nice if one gas would work on both steel and aluminum.

I use 75 Argon 25 Co2. I started with pure Co2 and did not like it at all. I use ER70S-6 or ER80S-D2.

@totensiebush 7 лет назад

I won't claim to be a good welder, but for relatively thin materials I find the key to getting CO2 to work reasonably is a VERY short arc length. For thicker stuff it isn't quite as close, but I still end up running closer than I would with C25.

Anything over 2.5 forget about it

Change wire to Flux core and be amazed.

Can you revisit this with pulse mig

@lukeellis2961 Год назад

would it be alright to use pure argon with mig just welding on car bodys mainly just tack and plug welding

@totensiebush 7 лет назад

Since you're trying some things against normal activities... any chance you could try AC TIG on steel? Of course, I wrote that before I saw the end of the video where you were saying you want to do things that're fun, and that this isn't.

I work in a snowplow up fit shop I hadn't welded in 25yrs and it was stick welding, they use mig welding which I had not done and are using 98/2 mix and my welds look like shit and I tried everything I could think of to change the look of the bead all big and ropey, I had a sneaky suspicion it was the gas.

@jeffmay1332 7 лет назад

Is bead blasting metal down to clean white metal as good as grinding or sanding to shiny metal when welding?

@bobmoffatt4133 7 лет назад

Sure

Ceramic flap discs are good too. Some scale is just too hard for zirconia alumina regardless of the grit.

@bobbyphillips9544 7 лет назад

I use pure argon (100%) on mild steel and get good welds

@totensiebush 7 лет назад

GMAW? What thickness? What wire size? Have any pictures?

@phiksit 4 года назад

My neighbor claims he can MIG with argon. But he's the kind that thinks he knows everything and can stand around all fucking day telling stories to prove it. The one time he needed something welded he had to borrow my welder and have his buddy come over to weld for him :)

@paulbernett1581 3 года назад

Try 95.5 argon oxygen it will spray like crazy. and it will also wet out better on short arc and it will lay flatter and penetrate deeper trust me. Bernett Custom Welding

These are super great vids for all things welded, but you should do a few more bite tests, show us how much it wetted. Thanks and super video of the arc & puddles.

@MadMetalShop 6 лет назад

Don't use a drag angle with solid wire and your beads will lay down. I have never found a use or benefit draging solid wire.

I made the mistake once at work and grabbed the argon instead of 75/25. Sucked moving that bottle back.

@scottmcelhiney323 6 лет назад

I did the opposite in a Tig booth. One of the high school students left an empty bottle and I was feeling nice and changed it... 90/10 instead of pure argon. No one noticed for three days. Oops.

@lukepodmore7810 7 лет назад

Thanks bob learned something new

@karstenshaw3377 3 года назад

While I agree on the gas, I feel like he wasnt doing the proper movements to make a good weld. Small e shapes are what you want to do, and he was barely doing a back and forward. I may be wrong. But that's how I was taught, and it's always given me great beads when I have the setting right.

Could you do a video on Open Root oxy acetylene? It is part of the process towards the certifications i would like to acquire, would love to see a video on it

@benmolendyk771 Год назад

Thanks

@benscott19841 3 года назад

I wish i had found this earlier. I've been thinking I just suck at MIG welding and it's my gas. I mean still could be me, but I have hope.

@garyscoville7741 7 лет назад

Hi Bob. Gary from CT here. You mentioned "spray" welding, what is that?

@markthomas36 6 лет назад

Thank you. I simply wanted to know if pure argon was suitable for mig / mild steel, and I have my answer, Don’t. Cheers

@prestonvandivier1379 7 лет назад

I fucking love the outtakes at the end. keep it up guys.

@satamanschmidt3428 4 года назад

Just another example of: "l'll save a buck." Anybody that's lived for any period of time realizes that's a certain recipe for disaster. The truly hot setup that I've gone to is 90-10 Argon/CO2 for all steel mig welding. My HTP Propulse 200 loves it for all modes including pulse spray arc along with normal short circuit MIG. Spray arc is just a thing of beauty.
