Great video, I have never used a spool gun but recently got one and I’m getting ready to try it out. I have. Lincoln 180 mig machine now and will be using the spool gun with it. The spool gun is a Lincoln also. Maybe I missed it but I’m assuming that I would need to use 100%Argon and not the75/25% gas that I now use with the steel mig setup. Thanks
Michael, you are correct, 100% argon, sorry we left that out......and you need over 30 is a good place to start....setup can be tricky, you may hit the right parameters right away or it may take a few settings....it has a narrow range that works well....also, clip the wire for each start, that will make starting easier.....always push, never pull. and pause at end of weld to fill crater to avoid a crack. if you can, do not push toward an edge as the heat build up can cause you to blow through the base material.....and clean you aluminum with acetone,alcohol, or lacquer thinner, xylene, toluene before as it will take any oils or hydrocarbons off.....a hand wire brushing also helps after solvent leaning, watch this video for more info on cleaning aluminum, all these things really helps to get a better weld, hope this helps, Paul....ruclips.net/video/zgsqAjBXU94/видео.html and ruclips.net/video/k-YF0AaGvmk/видео.html
@@ypaulbrown Isn't 100% argon only for Aluminum or is 100% for any material?
100% Argon for MIG Aluminum, TIG aluminum, and TIG steel. Mix gas for MIG steels depending on application.
Your efforts on the videography of the actually welding process are greatly appreciated. Nice work!
love that camera action, makes it so clear what is going on...
really appreciate that, Andrew or 'Camera Guy' is very good at what he does.....thanks for watching and commenting , Paul
Great closeup of the wire and puddle!

I agree 100 percent

@@ypaulbrown Hi Paul, awesome video, thanks! You know how we TIG aluminum on AC, is it the same for using a spool gun? You can't use a spool gun on DC? Thanks again, subscribed to your channel 👍
@@brianswelding good question, MIG welding aluminum is done with DC +, the same as for steel, stainless, silicon bronze. the 100% DC+ arc cleans the aluminum oxide off the material, just like with an AC arc, but is 100% instead of only partial % +....I hope this helps, Paul
Camera takes are very impressive. The best I ever seen. Great job!!
Captain, yes, our Director, Producer, Cameraman, and Editor is one heck a Video guy.......he even looks like Francis Ford Coppola........Give him a big shout out, Andrew never gets the credit he deserves........he is in a video weld.com did about how to get grit Arc Shots......check it out.....ruclips.net/video/qbbi-0ldkIc/видео.html
I Have never seen 1in Aluminum welded in my life lol very informative thank you
nobody's, man, that 1" really suck up the heat, as I state, you would need
450 or more amps to do that with TIG....and a he/ar mix of gas which is super expensive....
cheers, glad this helped...thanks for commenting and watching, Paul Brown
The camera footage is absolutely terrific !
Vieuxacadian....our fantastic camera man Andrew get to take credit for that....
I did do the camera work on the weld pool that is bright silver, you can see the
camera mounted to the spool gun.....thanks for commenting and watching, Paul Brown
That was a good overhead arc shot
Thanks Richard and thanks for watching and commenting, best wishes, Paul
Thanks for bring back some old memories. Ran an aluminum spool gun back in the 80's.
I still run one and love it for many things......it has it's place for sure and is not some toy as many consider it......best regards and thanks for watching and commenting, Paul
I do a lot of Al spoolgun for reefer trailer repairs as the insides and frame rails are all made from aluminum. It's fun and you can fill large gaps. Most people forget to run a much higher gas flow to protect their weld puddle.
you are so correct on the others using low gas flow, I think they are trying to save argon......it is not worth doing as that aluminum needs protection......thanks for watching and commenting, Paul
What CFH you use?
@@Chris-vx5kpI need to look at my regulator. I run it pretty high as like the guy above this comment stated a clean weld is worth the cost of argon.
Good job explaining and showing the spool gun in action. I've got 2 welders with 2 spool guns and one of these days I'll try them out. LOL
get on that spool gun ya hear....you will like them once you try .and you can run flux core, solid steel, silicon bronze in them too, not just Aluminum..... if you have one with a long lead, it might be handy getting into places that were difficult before, like a boat......thanks for watching and commenting....Paul
Great job on explaining and demonstrating spool guns. Very insightful .
Thank you so much, that really makes my day hearing that...I always try to give
the information straight and correct, and simple.....cheers, thanks for commenting and watching, Paul Brown
This is brilliant thanks. I'm about to buy a new welder that can run a spool gun. This helped me to understand the animal much better.

Thank you Derek, appreciate the feed back, thanks for watching.......Paul
Back in college we used Lincoln Push-pull guns for aluminum. Used the training Lincoln C300 with it. Not every shop has that setup, I think more still use spool guns.
Aaron, yes, Push/Pull guns are a lot more expensive, the advantage is lighter weight, and the fact that you can use a 20 lb spool of wire.....Both Lincoln and Miller use push/pull systems from MK Products, the original maker of the Push/Pull system, called the Cobramatic due to the shape of the gun looking like a Cobra......thanks for watching and commenting, Paul
My shop has both!
Interesting , thanks .I have a spool gin I've yet to use . This really helped.
Bob, get out there and use that spool gun......any mig aluminum can take a bit of fiddling to get the right setting of volts and wire feed.....one change at a time......hope this helps, thanks for watching and commenting, Paul
I've been wanting to get a spool gun for my 180. I found your video very helpful to understand what I need to do. I have an aluminum horse trailer that needs some work (horses are rough on things). I'll save your video for later reference when I get the gun. Thank you very much, sir!

I build aluminum gangways but I use a Lincoln Magnum Pro AL push pull gun. Amazing piece to use.
I have been doing a lot of aluminum fab with 6063 and started withTigging, what a pain that was...got the customer/boss to let me MIG with our Miller 30a gun.....10 times or more faster.....certain things need TIG, and Others Need MIG.......my job needed MIG......thanks for watching and commenting , Paul
We use spool guns for very thick aluminum armour plate
John, right on......like I show in the video, they are capable of welding some thick material......thanks so much for watching and commenting, from all the Hosts at weld.com, Paul
Paulie tell Mikala I said hello I have a spool gun and I was successful pre heating the thick aluminum and then using the spool gun to make a weld the weld was very fluid from start to finished it also prevents an over crowned bead because the aluminum was preheated you can rest your aluminum housing on your charcoal grill to maintain your heat temperature also cast iron can be put on an ignited charcoal grill to slow down the cooling rate so the weld can wetting into the joint easily
Thank you Mohammed for that great information.....we hope yo are doing great.......thanks for watching and commenting....Paul
@@ypaulbrown I have a power mig 140c Lincoln electric machine so when I hook up my spool gun on that light duty machine the aluminum bead is very convex because the current is not hot enough to get a fluid weld pool so I use my small propane torch and preheat the basemetal to get a fluid molten pool
Love the POV camera angle!
thanks for commenting and watching, Paul Brown
Love running aluminum spool!
Hey Bearded Welding Teacher, spool gun mig aluminum sure makes life easier.....thanks for watching and commenting, Paul
great knowledge.Thanks.
glad you liked, thanks for watching and commenting, Paul
great video paul, im hoping to get a spool gun soon so i can start taking on aluminum work
MCF....you will love it.....it does take a bit to set up proper volts/wire feed speed.....nothing too complicated, thank you for commenting and watching, Paul
Hi, great video with very good pros and cons description. I particularly liked the description of the best applications of each welding process. A small comment though you could have added the advantages of pre-heating aluminum before you start you welding, particularly on large cross sections. also your welding camera rig does a very impressive job. bye
thanks for viewing and commenting, cheers, Paul 'Paulie' Brown
Very informative 💯
Thanks so much for watching and commenting, Paul
Great camera shot on the weld😊
thanks for commenting and watching, Paul Brown
Great info straightforward thank you
glad you liked Jeff, Spool Guns are great tools......they get you into spots that would be very difficult using TIG and have amazing oxide removal and crud removal too.....they have a few quirks as far as set up [volts and wire speed] you just need to find the sweet spot and go from there......thanks for watching and commenting, Paul
@@ypaulbrown hi paul! I am very much old school, my dad was literally fonzy machining his own engines and building his own cars at El mirage back in the 40s and late 50s. His flatheads ran up to 211 miles per hour in a streamliner back in the mid-50s while he was over in Korea! So I was born with an oxy acet torch in my hand. After all these decades including learning how to braise aluminum with this torch I am finally beginning to concede that I need to look at a little bit more modern welding equipment, although I can give most a good run for their money between my torch and my arc welder! Although TIG has always had my interest I just could never see paying the money with the limitations you have with that equipment and I kept thinking to myself that one day they will get these mig/ wire feed welders up to that par level where they can effectively weld like a TIG unit! And it looks like we are there! You're always clear and concise and straight to the point it is really appreciated thanks Jeff
@@jeffalvich9434 thank you so much for the kind comments.....and thank you for taking the time to comment and watch weld.com videos......you can actually TIG weld with any DC stick welding machine......just not aluminum, were you need AC for the positive side of arc to remove the aluminum oxide layer.....I started out with oxy/fuel back in 1972, immediately using stick with an old Airco unit......I cannot say I was very good back then with stick welding, but the oxy/fuel was easy for me to pick up......the MIG machines today are very easy to set up and do a wonderful job. back in 1980 when I decided I needed an off road race car, allI had was a Lincoln 225 AC buzz box and 6011 rods.....the first time the car was raced, the driver flipped it 3 times, not one weld cracked, I was thrilled by the quality I had put into it....so was the driver......if you are interested in doing TIG with a stick welder....check this out.......best wishes, Paul...Beau has a lot of good information in this short video...ruclips.net/video/atSIGSTToQo/видео.html

Very nice video Paul i have never use the spool gun and it looks very powerfull i like the cleaning action !!!!!!!!!! i weld many stuff from sailing boats and its very hard with tig :( this sistem its grait 👍👍👍 thanks Paul
George my friend from Greece......so good to hear from you again....it is a game changer for sure, make sure to use the 5356 filler wire if you are working on Marine/Boat type welds, it is stronger and has the magnesium you need for those alloys.....thanks for watching and commenting, Paul

I just want to say, I absolutely appreciate you for everything you teach us. I also wanted to know, are spool guns semi-universal? For example, if I have a Lincoln that's set up for a spool gun, could I use an Eastwood spool gun?
unfortunately they pretty much need to be configured for the machine they are designed for....I hope this helps, thanks for viewing and commenting, cheers, Paul 'Paulie' Brown
Love my spool gun. Have only practiced with it a few times but it's a hell of a lot easier than TIG. Doesn't look as pretty, though.
pretty does not mean strong......and when you have not spent a Grazilian hours learning TIG, the MIG spool gun pays off.....there are places you can get that would be very difficult with TIG even if you are very proficient.....
can you tell I like Spool Guns....they have a lot of advantages......I hope this helps...thanks for commenting and watching, Paul Brown
Good video, but never heard mention of what size tip,what CFH it was running. Thanks for the video!
sorry about that Grunfield.....we were running 40 cfh argon, and the tip was a .035....
you need to run a slightly larger tip than for steel, as the aluminum filler heats up and expands
and will seize up in a smaller contact tip.....I will go to a .046 if using .035....as the filler has
a large helix curve, it does not seem to effect the electrical contact....hope this helps, thanks for commenting and watching, Paul Brown
I have that same MIG machine, but don't weld much heavy aluminum.
Randy, one day you will get some 3/8 or bigger and be glad you have a spool gun...Paulie
For thin material you can get pulse mig and for the stack of dimes look you can get double pulse machines. you can get that with spool guns on some machines.
a small question, what effect does the nozzle size/shape play? aluminium tig runs better with a smaller cup, is alu mig the same?
tweake: I have not done any testing on nozzle size to compare to tig nozzle size so I really do not know. The reason the smaller nozzle on tig helps is that it makes a smaller etched zone and the arc does not want to wander and go as wide. I learned this from our friend Justin from Las Vegas from weld metals online. as far as the machines you mention, those are very expensive and out of each of most weldors as they are industrial type machines....you can do bump welds on thin material and get a kind of stack of dimes, but what you may not realize, those pretty divisions between weld nuggets are stress risers and make the weld weak....I hope this helps you and others, thanks for watching and commenting, Paul and the Gang from weld.com
@@ypaulbrown basic pulse migs are affordable. I have one, but its only pulse on the whip. A full commercial pulse unit cost similar to a Lincoln. Sadly its the usa market thats holding you guys back.
@@tweake7175 a lot of that is lack of support from the European manufacturers here in the US, service, parts, availability and dealers not wanting to get involved with another brand.........it would be nice to have access to some of he European equipment, but the Big 3, M. , L, .E ...have the commercial market pretty wrapped up....as they have been in business for over 100 years each here in the US.....thanks for commenting.....we appreciate it.....Paul
Sir . Do you think 200 Amp MIG machine with 22 Volts max setting , could go into spray transfer using 0.030" aluminum wire(with 100% argon) ? I very much doubt .But i don't trust short circuit transfer on aluminum. I'm to weld patch piece on 2016 F150 aluminum fender. It's 0.055" thick aluminum sheet. My plan is to go into spray transfer and weld the patch spot by spot been careful not to burn through. I have big doubt it's going to work . I would try though. Don't wanna learn AC TIG or having to buy very expensive pulse mig machine.
Peter, I have welded a lot of 1/15 .062 6063 and 6061 with .035.....you 200 amp machine will handle this. as far as short circuit, welding a patch to a fender is not really structural, so short circuit should be no problem.....but if you want to 'bump' weld with higher amps in the spray mode, that will work also.....you say your machine only goes to 22 volts, do you have a meter that shows that, or just setting controls....I spray at about 22v and 220 ipm with .035 on the .125 6063 I weld all the time, it is in a spray at those settings......give it a go and let us know, thanks for watching and commenting, Paul
Does dipping the nozzle in splatter shield products effect the weld on aluminum parts? Or should we stay away from it?
Joe, it does not seem to bother, but you really should not need to use a nozzle dip if your parameters are set correct....I would use a spray type instead of getting the gel.....hope this helps, thanks for commenting and watching, Paul Brown
I've been looking at spool guns and I am disappointed in their common length of 10 ft has anyone figured out a way to build an extensions for one
Nick, you are looking at the less expensive models.....you may only be able to use
on the type machine you have.....with a little ingenuity, you should be able to make an extension....
I know Miller makes one, 25 feet, it is about $1,200 for just the extension....hope this helps, thanks for commenting and watching, Paul Brown
@ypaulbrown I ended up getting a everlast with a 25ft spool gun
Welding anything thinner than 3/16 is actually pretty difficult with a spool gun depending on the type of weld. A large piece with really good fit attached to a thicker piece is gravy with a slower wire speed but without a decent cross section your better off in tack city.
Justin, I agree with you , thanks for watching and commenting, Paul
Nice. 100% cleaning action pretty cool.
Sounds like you set the voltage high enough for spray transfer ? Is that correct ?
In other words it's set up like mig using a spool gun with higher voltage for spray transfer... ?
Any tutorials out there on it ?
Thanks 👍
Drum, you are 100% correct, aluminum mig likes to spray, you can also short circuit, for very think 1/16 inch material, but really risk birdnesting. The one thing not mentioned, is to always push the weld, you are cleaning the base material before you get there much better.....you end up with a nice clean shiny weld like shown, if you pull the gun, it will be gray and very sooty......hope this helps, and thanks for watching and commenting, Paul.....
the tutorial you are asking about, is probably experimentation, aluminum mig has a very narrow sweet spot, so you just have to experiment. I find, a push/pull technique helpful for me, where you move slightly forward 1/8 to 1/4 inch, then pull back to the existing bead and lay in some wire, then repeat. this gives the puddle time to solidify and also not burn through, otherwise, the puddle can be very fluid and start wandering on you.......as far as volts/wirefeed speed go, start with what we were using, 22 volts for so and 300 ipm or. more.....I usually use .035 wire, but the lab only had .030 on this day.....they also make 3/64 or .046 for thicker welds.....we missed mentioning the gas , which is of course Argon at about 40 cfm.....hope this helps, I will try and answer any other questions you may have.....Paul
@@ypaulbrown NICE 👍 TY
@@drumtwo4seven marvelous
@@ypaulbrown you answered just about everything and then some. I appreciate it very much 👍 I wasn't sure about any of it now I feel I have a good place to start from... Interestingly those are the same settings I use for dual shield except c25 gas not pure argon but close to the same flow 30 to 40 cfm... push angle too... 22.5 voltage not 22 but still close
Thank you again 👍
Could you use the spool gun for steel welding? I cant find anything online answering that so I hope someone can answer this pls and thxs to who answers this.
Kenji, sorry for taking so long to get back to you....yes, it works fine for Steel, Stainless, Silicon Bronze....it is 1 pound [1/2 kilo heavier] when using those materials, as they weigh more than the aluminum....the great thing is, you can get further away from your machine.....as the better spool guns have 25 foot [8 meter] leads....I hope this helps, Paul 'Paulie' Brown
Hi Paul, I saw you commented to someone that spool gun can also be used with silicon bronze wire. Is it useful for welding brass? If I need to weld brass rectangular profiles, 1/16" thick, can this provide a solution? Can you elaborate a little more about this? Or did you mean just for brazing steel or something like that.
You can run sibro wire in a spool gun with 100% argon. Typically its a spray arc.
It will work good
@@ZILAwelds thanks for chiming in Zila....good information.......cheers, Paul.....
as our good friend ZILA mentioned....you can use silicon bronze with 100% argon.....it is a Braze weld and is very strong....check out this video we did a few months ago ..........this should help you....thanks so much for commenting and watching, the Gang here at weld.com appreciates it......go check out ZILA.....Thanks ZILA....Paul...ruclips.net/video/fvR2q-NuZB0/видео.html
@@ypaulbrown @ZILA - Great video! I have a Miller Syncrowave 210 (multiprocess) and primarily TIG, but have used my spool gun for tacking and other hard to access welds (aluminum boats, etc). I've TIG brazed using silicon & AL bronze, and just saw the video on mig brazing. So, I use 100% argon for aluminum and silicon bronze with a spool gun; what if I picked up a couple of 1LB spools of ER70S6 or 309? Can those be ran with 100% argon in a spool gun, or would I be better to use C25? (I actually have a Millermatic dedicated MIG machine with C25, but am just curious) Thanks!

How do you stop the black soot when welding Aluminum?
good question Marty, that soot is called Smut believe it or not and is magnesium oxide and aluminum oxide so dense it does not allow light to reflect back through it. the way you keep from getting it, or as much , is by using a push method, do not pull the gun. also stick out length of wire can make a difference and gas flow.....you need 40 cfh argon, many try and skimp out and use 14-20 cfh,,,,,that will not work.......I hope this helps, thanks for watching and commenting, Paul

Why haven't they invent hybrid system for Aluminum, a secondary drive motor in the gun but the spool stays in the machine. Then the tensioning wheel in the machine would only hold tension on the spool...
is the mig gun with aluminum set to AC or DC?
DC positive ....same as for steel or stainless.....thanks for commenting and watching, Paul

@@ypaulbrown another quick question, will this work on Cast aluminum?
@@guss1470 yes it will work on cast aluminum, and most times is easier that tig in my experience......due to the 100% electrode positive cleaning action...[cast can be dirty]...you still need to try clean the casting first.....and it might not hurt to heat, and apply solvent, and reheat a few times, use a propane torch, or oxy/fuel.....to clean any grease out....hope this helps, Paul

Materijal of alumini you mast with burner heat up than you Can welding alumini hot
pre heating is true sometimes, but a lot of aluminum welding is not preheated, the small area of the arc with mig puts more heat into a smaller area than TIG or Stick welding. welding large parts can be difficult sometimes due to size and the heat dissipation that aluminum has....so heating can be beneficial on thick sections. thanks for watching and commenting, Paul

Standard 3m 10ft mig gun water cooled teflon liner decent 4 roll drive feeder on a double pulsed mig with the feeder hung on a boom and you will never use a spool gun again we often run a full 7kg spool none stop with maybe only 1 tip change 250 to 280 amps
Try that with a spool gun soon get sick of buying them dinky 1pound spools never mind holding the clumbersome spoolgun all day
well, when you work on a boat, on a trailer, you might have to change your mind about that statement....10 foot lead can be real difficult to get in to a lot of places no matter where you are....and not everyone has the luxury of a boom.....or a pulsed CV machine......thanks for commenting and watching, Paul Brown

Often work on boats moden pulsed migs are light enuf to drag round and mig gun is alot smaller to get into tight corners
Ive used both and for me its a no brainer standard gun for me
Maybe sets ive used but double pulsed mig makes a neater weld than i could ever get with a spool gun but as you say not everyone has the need or enuf work to justify to spend the money on a double pulse mig

The weight is gonna affect you welding
all depends on how you hold gun, how experienced you are....there are many ways to hold the gun too.....for putting a lot of metal down fast, the only other alternative is a push/pull system that can be 3 to 5 times more expensive......thanks for commenting and watching, Paul
ah yes.. spool guns.. for people who cant afford a professional machine with a 20m push pull gun lol any machine that needs a spool gun to run alu mig aint a good machine
Yes, many do not have the 5 to 10 thousand dollars or more needed for a push pull system....and only have limited use needs. It is marvelous that you have these resources. thanks for watching and giving your valuable input. Paul
I don’t need to change liners whenever I want to weld aluminum.
@@apenza4304 no need to change liner with a spool gun, as the liner is only maybe 4 inches long. on a regular mig gun, the liner needs changing to one with teflon and U Groove rollers are highly recommended as it is much longer and the aluminum wire is no where near as stiff, for mig aluminum with a normal high gun, you can use 5356 wire instead of 4043, it is stiffer and stronger...yu also need to keep the cable straight to keep from having resistance with bends in the line..you need to use a larger contact tip also due to the wire expanding when it heats....for instance, with .030 like we used, I would want to use a .045 contact tip. hope this helps....thanks for watching and commenting, Paul
@@ypaulbrown Sorry for the misunderstanding Paul as I meant to respond to gold Elmo as I do use a spool gun for aluminum for all the reasons you explained in your video. My comment about changing liners is if I wanted to push aluminum wire through my mig torch line I would need to change out the liner to a Teflon one and this being another benefit of using a spool gun when switching over to aluminum.
@@apenza4304 Apenza, thank you for getting back to me, yes, you are correct in what you say.....If you were to use a Teflon liner in you mig gun, and run steel through it, it will cut the liner and ruin it very fast. cheers, from Weld.com, Paul

what is difference between spool gun and classic mig torch?
Dollars, Pounds, Marks, Francs,ect.....Basically, the spool gun has a motor that drives the filler wire.
so you are not sending the wire down a 10 to 15 foot liner.....only a few inch liner....so there is very
little chance of it binding....you also change the speed of wire feed at the gun and not the welder....
there is a weight penalty though, as you are holding the 1 lb spool of aluminum on the gun itself ....
and the bulk of the spool gun compare to the mig gun,
but I have handled some mig guns that were also very bulky too....
