Watch this video to learn how to MIG weld aluminum with a spool gun. When welding aluminum, you are dealing with a much softer metal. Because of this, you’ll need some special equipment and follow different procedures. Because of its softness, aluminum wire is difficult to push through a standard MIG gun. That’s why we recommend the use of a spool gun. This reduces the distance the wire must travel. Learn how to MIG weld on aluminum with a Millermatic and a spoolgun in this video.

I'm a miller fan. Every school I've been to uses millers, I'm a journeyman (Alberta) welder, and although my shop runs lincoln's and esabs, I prefer miller. I'm also shocked nobody is asking about base metal and filler metal types. Had huge issues running 5356 wire on 6061-T6 pipe with a spool gun. 4043 wire was much easier, but still had issues. (hot cracking with full penetration with both types) Tig is the only way to do aluminum in my opinion. No problems with 4043 or 5356 with tig.

@TheRealSuperSlayer 13 лет назад

Anyone who actually welded professionally at a professional fabrication assembly shop, used monster sized Millers. Lincolns are for repairing your parents railing, rewelding that plow that keeps breaking and spot welds in the driveway and that's about it.

I know this comment is ten years old, but it is hilarious.... in a good way.

@mannyfranco8955 2 года назад

Good Video for beginners!! However try to avoid large weave beads on aluminum!! A straight weld or short stitch motion will get you better results in my opinion.

@3Mudbone1 13 лет назад

I bought a Miller Spool gun about 14 years ago for about $1,000.oo and have hardly used it yet. I have used it a little with my Millermatic 250MP. I appreciate the tips, I intend on watching this a few more times in the future.

@jahmarley420 11 лет назад

I would buy a Miller over any welder! Have built 3 bikes over the last 8 years, and never had an issue with welds not holding up or breaking. Miller welders makes welding easier, and the end result is a clean and durable weld. If your thinking about buying a different brand, just save your money and get something that is reliable and will last forever! Cant wait until I save up to buy this one! My name is Justin and I approve this message! :D

@peanutsmith1462 2 года назад

We just bought this set up today I’m use to the Lincoln power mug 350 with push pull gun it’s different but hey it works

@trashtrout 13 лет назад

You can make X-ray welds with the welder in video. Have been doing it for almost 25 years.Secret to Alum mig welding is clean,clean and clean some more and no air moving at all.

@SupaNautica 6 лет назад

The most important thing is to turn up your gas flow to 30 and push, never pull. Like steel, migging thicker material is easier, so start thick, get your head around it and then work down to thinner material. If you do that, you will have great results, moving fast, clean material and settings are important but that gas flow is top priority.

@Ma77riK 12 лет назад

same here in northern cal, at our shop weve got a miller mig with a spool gun and tig machine, other local shops here run millers as well

@carlielleenterprises 12 лет назад

I'm running a 140 with a 100 spoolgun and it works really well!

@ChrisLawley43 15 лет назад

I agree some of the best welders out there will tell you allday there not that good and those are the ones you want to be friends with.. there the best

@fabfabber 14 лет назад

@Cuyoherna During the process of getting certified, we discovered the best gas to use to pre-heat aluminum is propane cuz it does not leave the black soot which contaminates the metal. Also, the ideal temp to start welding the thicker alumnum is between 200-250 degrees F.

@Delticola 13 лет назад

@Delticola No, it wasn't you that was 16, it was someone else from the other post below. I'm confused now, I think I ment to respond to that 16 year old kid. Or maybe I confused your comments with his. Either way. We agree on Miller. Really nice stuff. I've got the 212 Millermatic and the 180 diversion in my home garage. Still learning the Tig however. Something almost funny to say, the Harbor Freight Tig Welder, the 230 Amp blue box, is a fantastic DC TIG.

@marcmccourt843 8 месяцев назад

In other words forget this video and learn on your own!

@Delticola 13 лет назад

@zpgJiggleBilly I see that you're 16, perhaps really good at welding, perhaps having $43 an hour job offers. But both Lincoln and Miller are fine pieces of equipment. Miller is more expensive by far, and they stand behind their product very well. Lincoln might sell more machines because they have their stuff in Home Depot and have larger distribution warehouses. But Miller builds their machines very well to last a lifetime I believe. At my job our shop has had a miller Mig for about 35 yrs.

@bloopbloob 11 лет назад

And I'll add, yes anyone can be a welder. Just pull the trigger and follow the line. But to be a good welder is something very different,and is why you can make $35-50/h here as a journeyman, and $110-160/hour as a b-pressure with a truck. A lot more to it than garage welders think.

@zpgJiggleBilly 13 лет назад

@Delticola How did you come to the conclusion that I am 16? Also having both a miller and a Lincoln, I can tell you that at least half the lincolns I have used suffer from very slight but noticeable amperage fluctuations while welding, causing reduced penetration and over all poorer quality of work. However when I just want to get two pieces of metal welded together just to weld them together I will go with the lincoln, when I am working on a major project I will use miller every time.

@TSorovanMHael 14 лет назад

Not really necessary to use a spool gun. You can get by with some slight modifications to a normal MIG lead. 1)Use teflon guides and a teflon liner. 2) Use smooth double U-groove rollers. (Rollers meant for steel are usually single V-groove ) 3) Use the lowest amount of feed tension possible. 4)keep the liner and tip clean. replace tips often 5)keep the tip recessed 1/8" inside the nozzle-this protects if from heat, spatter, and fouling. 6) use US made wire & tips which have better tolerances

@xECHOx123 13 лет назад

@xRaw381 yeah i working on it im in auto class it will help me for apprentiship for layying

@fabfabber 15 лет назад

I've been welding aluminum for years and prefer it WAY more than steel. Yeah, steel is more forgiving, but it's nice to be able to pick up a 20 ft joint of 3X3X1/4 by yourself and cut it with a chop saw.

@MillerWelders 12 лет назад

@katrinavontramp Now that''s good to hear Katrina. Thanks for letting us know.

@LMF5000 14 лет назад

How do you manage to stop the camera from being "blinded" by the brightness of the arc and just showing a completely white picture? Did you use a special filter or did you put a welding mask in front of it?

@doughboy5840 3 года назад

Not sure

@TSorovanMHael 14 лет назад

The inconsistent feed rate shows from the start in the first weld. Push-pull with u groove rollers are so much better.

@backoff2day 15 лет назад

I like the push/pull gun myself but the spool guns arent too bad

@welding4744 13 лет назад

Very good

@LincolnSP150 14 лет назад

Very informative. Thanks

@rdecaserio 15 лет назад

A Pyton gun is a great choice in my opinion..

@davidkirkwood5673 4 года назад

What do you need to run this spoolgun off of a gas driven welder?

@MillerWelders 4 года назад

Hi David. Bobcat’s require a WC-24C to run a Spoolmate 3035. They also require a WC-115S with a contractor kit to run a Spoolmatic 15A or a Spoolmatic 30A. Trailblazers and Big Blue’s require a WC-24 to run a Spoolmatic 15A, Spoolmatic 30A, or Spoolmate 200 Series. Please let us know if you have any additional questions.

@analgorilla4609 12 лет назад

I always thought you could only weld aluminum with TIG. Good to know.

@500passwords 15 лет назад

cool video

@TRAVISM3 14 лет назад

jeez after reading all these comments i might just try to weld my lungs shut

@ChrisLawley43 11 лет назад

not true on the 13 an hour thing hell welders can make way the hell more then that but you are right it is best to learning to read prints will get you further a long.

@prototype9000 14 лет назад

what about the mig wire that has teh shielding gas in it

@fritzkat 13 лет назад

i never liked a spool gun and the way the wire swirls oul.the xr gun or the python made by lincoln/cobramatic is my fav

@dekesdad 12 лет назад

Hypothetically, let's say that I want to build for myself an aluminum framed ultralight aircraft. If I get it all jigged up and spot brazed and checked it's square and true, what's to require me to TIG weld it versus MIG weld it?

@chipewayan 15 лет назад

can u use straight helium or is it a mix with argon

@saucychurch23 16 лет назад

cool stuff

@aleximorrissey9827 8 лет назад

Hey I just started a job in a new shop with this machine and a spool gun. Doing aluminum. Not sure if it was calibrated. There is a ton of spatter and scorching. I'm dialing in the machine constantly but not getting accurate welds. Welding 6061 alloy with %100 argon. Getting good penetration but at the end of a fairly short bead (2" long) it starts to burn through. The cold start has me with fat and high beads at the start that need a lot of grinding and the end of my weld has shallow welds with undercuts that need a second pass over them to be level with the material. It's a mess. Welding pipe-to-pipe 3/16" thick. Aside from these issues my question is this: does this auto calibrate function merely dial in the spool gun for me to then adjust my own voltage and wire speed or does the auto calibrate work so I just "go" and the machine senses the correct wire speed and voltage on its own? And will this function sense when the material gets hot so it dials it back automatically?

@aleximorrissey9827 8 лет назад

Whoops. This is meant for the spool gun video. Any takers?

@MillerWelders 8 лет назад

Alexi - can you confirm which spool gun and machine you're using? With a little more information, we should be able to help you troubleshoot the issue.

@melissaluna8218 7 лет назад

Miller Welders hey miller welders i am using the millermatic 350p with the 30a spoolmatic gun running 5556 3/64 wire and i am doing aluminum ceramic welding on navy ships i been doing real great on the verticals but horizontals been doing a lot of repairs can you provide me some settings and offcourse i have to run it with the pulse setting for rapidness thank you

@justboredanddumb 14 лет назад

it has to be mixed with argon. only reason to use helium is to get a hotter weld puddle.

@karlkassin 13 лет назад

i like the xr system better.8 also like how miller uses tghe lincoln cobra and renames it the python ....

@adronsmith9266 3 года назад

Can I hook a aluminum spool gun to a 250 miller

@MillerWelders 3 года назад

It is probable that a spool gun would be available for your 250, but it depends on which 250 machine you are inquiring about. You could email us at info@millerwelds.com or call service at 920-734-9821 with your model and serial number and a service technician would be happy to help get the correct part numbers for your specific machine. Thank You for reaching out.

@lb4906 13 лет назад

One thing you missed is that you use a larger contact tip than the size wire used to account for expansion, i.e use 0.035 tip for 0.030 wire. This is only for aluminum.

@therotaryrocket 13 лет назад

@xECHOx123 school is the best place to weld. If you go to community college and take a welding class you can just pay for the class, and then you get the opportunity to weld probably every day using the schools materials and facilities. I am so glad I went to auto body repair class, I go to fuck off with all those free materials using free tools. We had high quality paint, tools, paint booth, welders, frame machines, and whatever else. Had to be some of the best days of my life, learned a lot!

@xRaw381 13 лет назад

@xECHOx123 i am, ive got an apprentiship as a fabricational welder doing excavation builder, and im on £250 a week, its great :)

@ted850760 14 лет назад

@birch1607 but are you a 'certified' hung over welder

@Delta9D9 10 лет назад

Forgot to mention anything about liners for welding with aluminium wire (use plastic or nylon liners not the metal coiled liners), and contact tip sizing (use an oversized tip: .035 wire = .045 tip)

@melissaluna8218 7 лет назад

ChronicPain never use oversize tips. what kind of advise is that ??? use the correct size all the time.

@Vilagen 16 лет назад

good vid very helpfull

@yellowmetalcyborg 14 лет назад

@24preacherboy I'm making a welder and I'm not out of school yet. Indeed, welding expands your horizons and posibilities.

@shawnllorca4768 6 лет назад

That 240p tho. potato vision ftw

@FordRVRefrigeration 11 лет назад

Great video! Welding is a good trade. If you can weld, you can earn up to $140/hr

@karlkassin 13 лет назад

with a spool gun the wire swirls as it comes out which doesnt realy matter most of the time

@fabfabber 15 лет назад

Hey nacho I couldn't have said it better. I've worked with a bunch of wannabe's in the past who don't give a hoot about the work they put out. All they cared about was getting a paycheck. And the sad thing about those kind of "welders" is when you try to show and teach them the benefits of taking pride in their work, they look at you like, "man, get the f__k outta my face."

@pre3ston 12 лет назад

ever heard of blueprints or pipe takeoffs? that's why

@TheMaidenengland 13 лет назад

@xECHOx123 No mate you realy don't. It's not that good a trade to get in to.

@24preacherboy 14 лет назад

@xECHOx123 Why wait Start now. The world is a greater place when you can weld.

@ruben4936 3 года назад

ewm welding is to much cost more than even good als miller and migatronic.

@TheHockeyTank 13 лет назад

@xECHOx123 at our school we can weld in gr.9

@RedRyan 13 лет назад

@therotaryrocket I agree

@xECHOx123 14 лет назад

i wanna weld when i get out of skool

@skatman145 13 лет назад

@xECHOx123 same and im only 11

@Derouin91 14 лет назад

Thos were not very good welds.

@Optimus376 12 лет назад

SOOOOO TRUE. But some guys just can't weld. Like trying to teach a cat to bark. Math is your friend if u decide to be in this shitty piss poor pay kinda work.... ( But some weird way its gratfiying)

@fabfabber 15 лет назад

somebody needs to show this guy how to weld. Looks like there's no tie-in on the bottom side of the bead. I'm glad he doesn't work at my shop !!

@zpgJiggleBilly 13 лет назад

@XoCoPeNHaGeNoX I think most professionals that know what they are doing will disagree with you,

@rdecaserio 14 лет назад

You better know how to read prints, have youre own tool box, AWS G6 and be a fabricator or else You wont probally last long on a job!!
