🔥 Aluminum Spool Gun Settings Test

►SUBSCRIBE for new videos every Monday and Friday: goo.gl/FRdNss
Some people don't like spool guns because of their size, weight, bulkiness or some other reason; but if you're doing long production welding on Aluminum, what better way is there? In this episode we are going to play around with the new spool gun we bought for the Rebel 235 and see how it performs at varying settings.

I've been around aluminum Mig welding since 1987 building transport trailers, first using Miller's huge "camcorder" spool gun then later using their XR-30 guns, and lots of different makes and models since then. I am currently employed as an outside sales rep for a welding supplier and I frequently teach customers how to weld aluminum. For general purpose welding I suggest 4043 3/64" wire (because of its current carrying capabilities) and at least 35cfh Argon gas flow, and a 15-20 degree tilt back on the gun, always pushing the weld. In this video your fume extractor is creating a draft, which means you will need to add more gas. GROUND is very very important in all welding but is particularly important when welding aluminum, for your test area I would suggest that you find a way to ground each piece that you are welding, I'm sure you noticed those little arc tracks on the bottom of your coupons because your piece was trying to find ground. It will also help minimize burn backs to the tip as you start to increase your heat to get further into spray transfer. Keep up the good work, I'm very impressed with the arc stability of that machine, I haven't seen one run aluminum before but I may need to get one in my store for testing based on what I see on your video. Scott

[@MatiasArezo]

Hi how are you ? I have a question, do you need an AC/DC mig to weld aluminum with a spool gun, or only with DC you can do it? Thanks

[@sunrisetacticalgear2676]

@@MatiasArezo AC would be for TIG welding. For a spool gun you would use the same machine as a normal wire feed. You will need to change the gas to 100% Argon. You should be able to search your existing wire feed welder and see what spool gun options are available.

[@Froggies505]

So I run a 150 amp spoolgun on my millermatic 211. Welds come out good and shiny. But all around the weld is heavy black soot. I’ve messed with gas and everything else I can think of and I can’t get rid of it. Any and all thoughts would be appreciated. Thank you.

[@sunrisetacticalgear2676]

@@Froggies505 The black smoke next to the weld is normal, it’s called “smut” and is easiest to clean off after you finish your weld. I would normally keep a stainless steel tooth brush in my breast pocket to clean welds. Cleaning the weld joint of all impurities with a large stainless brush will help reduce the smut from the weld zone.

[@dragon5675kj]

Im a professional aluminum welder. Ive welded xray aluminum piping and plate for varies applications. I can start by telling you need more voltage.Also it ok to weld downhill only if the weld wont be pressured,strained or subject to vibrations. Uphill is the way to go but does take high skill level using cv. It is however easier with pulse mig.A push angel with high voltage tighter oscillations and faster travel speeds will deliver best results.

[@bobmoffatt4133]

Good stuff. Thanks for the feedback.

[@billmcyrus]

I was wondering about that, how well pulse manages the heat through a spool gun. Will all spool guns work with pulse if the machine has it?

[@thomaskincer1167]

I’d start around 23 24 volts

[@fredygump5578]

What you need is a stool with wheels, so you can roll between the welder, welding table, tool bench, etc without standing up. Why walk when you can roll? It saves time and energy. The first rule of welding is "Get comfortable." Right? That's what I was taught!

[@ltbuck1]

Very impressed! thank you for all your knowledge, thank you for sharing it with all of us. I’m a self taught welder never went to school for a bit of it. I’ve done some pretty amazing things with 3/8” AR plate, and I have welded a lot of other metals and worked a lot with a tig welder as well.

Thanks for your videos. Finally found someone that won't settle for "OK" quality work! It's a pleasure learning from you!

[@FollowerofYahuwah]

In school we did more of a forward whip and pause technique. It kept the weld clean, allowed to move ahead of the puddle for a good tie in and allows for reinforcement. Good for a sort of stack of dimes.

[@jasonrtaborsky4240]

Bob thanks. I'm glad I watched this video for the second time. I bought a brand new Lincoln 100s whatever. After watching, I didn't even take it out of the box.

[@lsellclumanetsolarenergyll5071]

Nice quick tip Bob when you do Aluminium also make sure you use the right wire and mention it in the video. On Crater fills try the O motion in the crater. If you can set a post flow or argon it will reduce your crater.

[@kwasg3]

hey bob, I didn't start liking my spool gun until I started setting up for spray transfer essentially. That fixed lots of things as long as you get and keep moving fast. Also I find it helpful to have a little pull angle going down hill with a little higher gas flow. You can hold the puddle up a little if you are a little cold, and that seems to work. Don't know if that is sound but my spool gun is on too small of a machine really, so necessity became the mother of invention...

[@mikev.1034]

I wasn't planning on buying a spool gun but, I am now after watching this video!! thanks

[@christopheringram568]

Bob, Looks good but remember that welding aluminum with a spool gun should be ran with a "spray" transfer. You are starting out fine but increase your stick out to maintain the spray transfer. running downhill can be done with a near perpendicular gun angle. Uphill sometimes is easier as you are not chasing your puddle. Another thing to help is to clean your oxide off the plate before you hit it with the arc. Chris Ingram welding Instructor Dawson Community College.

[@eriklarson9137]

The videos on your channel helped me understand your experience level. I knew you had to be a pro to correct Bob so I was in for a treat!

[@MrDDDEEEZZZ]

Nice demo! I like to work... and the humor is a bonus, makes it fun to watch

[@wrenchingandwheeling1589]

The black soot can be prevented with cleaning the surface before welding. Also increasing arc length to rid the spatter and crackle sound.

[@scotttipps8155]

Bob, for my spoolguns I have to hold and unusually larger gap from the tip to the material. Like around 3\4" or so. Turn your voltage up to about 23ish volts. Almost like a spray transfer

[@hubertrobinson8825]

Hello Bob. I've welded for 30 plus. I was welder in navy. We learned welding aluminum with spool gun vert up and overhead heavy plate 1/2 an thicker using short circuit transfer and co2 as shielding gas. Never used it since very interesting to say ther least but weld result was good. I've since used spray transfer on trailers and misc and used mix gas for heavy parts or build up on tire molds the gas shield is key. I use to have diagram of weld profiles with different shielding gases. Would like to hear your tale on how gases effect weld characteristics and heat imput

Love your gun cabinet ideas 👍😂😂

[@popswrench2]

near 20yr ago , truck shop , wespool welded ,heated , aluminum truck boxes (blacktop haulers) with 75/25 ar/co2 and did very well. i think part of reason was , we used MIG regular , so spool gun aluminum was easier transition , worked very similar.

[@quincymerriweather8163]

Wire feed aluminum downhill vs uphill mainly depends on scope; code or non code work. If the work is coded then uphill is your best bet to pass NDT or DT (non destructive or destructive testing). Thanks, Quincy

[@eriklarson9137]

Thanks for your post. I went and checked out all of your welding videos so I could see how you know so much that you could correct Bob.

[@royalspin]

LoL same here 😂 I'm just starting off with welding as well. For the past year or so I've been reading lots of books and visiting tons of channels on KZbin for instruction including several that are videos taken straight from vocational training classroom DVDs . There's tons of things to learn for sure . Before I got started the first thing I did was to make sure I had a safe way to do it by building a proper sized circuit ,with a breaker that could handle the amount of current the machine needs and made sure everything is built to code and then some . Only after all that did I think about using it . With all that said it takes practice and making mistakes, learning from those mistakes in order to feel confident and not be afraid to use the machine . First and foremost observe and practice all safety aspects of using the machine and absolutely make sure you have all the proper safety gear you should have before doing anything . Also just as there are really good channels on KZbin for instruction like this one, there's also some bad ones where they'll take shortcuts or they're not being very safe . If I see someone doing things like that I won't waste my time trying to learn from them.. period . Well anyways good luck with your endeavors on learning how to weld and be safe ! 👍✌️

[@robertuebinger4852]

I weld aluminum dump trailers and the best way to get rid of that hole and crater when u get to the end of the weld is pull back a little and make real quick tiny circles in place and you won't get that crater also turn the heat up and wire speed down and you won't get that fisheye as much

[@wrenchingandwheeling1589]

Robert Uebinger Or adjust your crater fill time on the machine.

[@blakekenley1000]

you don't want a tight arc with aluminum MIG. but you also don't want so little wire feed that you're constantly burning up tips. put a bushing on the feed spindle and grease it lightly as needed to eliminate chatter and inconsistent feeding. I run an old miller spool gun at elite trailers, my voltage is always set at 26.5 and my wire speed is dictated by hash marks around the dial, I tune it by watching my arc width on tacks and listening for a slight sizzle.

[@charliespann3967]

Great video Thanks, I noticed that when you moved forward the weld was quiet when you back up a little it seemed to pop a little. Could that be the soot ?

[@darcymcnabb9259]

It's realy good for field work .

[@garyhall867]

another way to stop fish eye/ craters is to use run on and run off tabs where they can be used. But still good runs as another guy said increase your heat a bit more.

[@MadMetalShop]

I do straight 90 downhill runs with our push pull pulse mig machines. The spool gun will do it too. I don't go vertical up because with alum it never works. You fight gravity and it ends up looking junky. Which is weird because I can weld overhead all day long if I wanted to with no problems.

[@johnmazza9432]

I've been thinking about getting into welding and possibly doing aluminum truck bodies and trailers. What do you think of the Miller 255 ? I was thinking that the push pull gun was the way to go because it just looks easier to work with and it can use big spools of wire that are more economical.

[@leonardpearlman4017]

I've watched this a few time, and read all the comments, too! You're getting some good ones in here, and also some other shop teachers, and people with long experience. I'm calling for some kind of congress here, where you have a room full of shop teachers, or a room full of people with deep experience on this (or some other) controversial topic... and see if we can advance the state of the art! I bet there's a grant for this somewhere. Anyway, this gives me a lot to go on. An aside about plastic gun liners: I've been saying all along that the liner should be Nylon or some special plastic with good compatibility with Aluminum. Teflon is not great for this! I know this shocks people, but it's true in practice and also in the literature. SO, I just found online a Chinese supplier of welding stuff that has a dozen different type of gun liners, one seems to be nylon/graphite! One is bronze wire... they don't say much and of course what they do say is sometimes garbled or just copied. I'm going to try a few, and see if one can't use a cheap MIG machine and a carefully maintained gun assembly to do routine MIG Aluminum. They had U-groove drive rollers, too.

[@dwightcarrell8808]

Taught simple classes on welding optimization. Biggest problem? What does voltage do? What does wire-feed speed (amperage) do? Most welders don't know. There are only three controls on a MIG weld and they need to be set in a specific order. 1) wire feed speed increases amperage that provides penetration. 2) Travel speed and angle fills the crater. 3) Voltage shapes the puddle. ( Also, are you weaving to try and imitate a TIG bead? Each time you weave you change the interaction of the three components and can introduce error. )

[@awesomemodzzz6856]

thanks for the video

[@vincegraham6867]

I weld aluminum channel probably about 3/16 wall thickness. We use 3/64 wire. About 22v 300 wire uphill doing sort of a whip and pause. Then just change the wire down to 260-270 and run to downhill pass. Just faster and quicker whips.

[@hunterromano5562]

I've just recently started using a spool gun. It's not my first time welding aluminum, but I can't figure this thing out. I'll get 2" that's pretty decent, then 4" of nothing but bubble gum. Wire is tensioned pretty well, and draws very smoothly and consistently, I've tried push/pull 90°/20° ect and I haven't touched the settings at all. It's my bosses $200 Amazon special which no doubt is a factor.

[@jeremyhanna3852]

On the craters I weld at a unnamed big trailer manufacturer 90% spool gun mig always push and uphill vertical what I do is go right to the end of weld speed up travel speed 2" from end of weld hit the end of joint then go back 2" just as fast ( the double pass at double speed puts same metal down) then at very end pull back slowly increasing your stick out to about. 3/4" as u pull away slow tipping the gun parallel. To weld not pulling straight out no fish eyes and your right fish eyes cause cracks every time

[@bigdave6447]

Use the same push technique on mig and tig . That spool gun is a lot better than trying to push the wire through a mig cable. Birdnest city!

[@jonnymandoonthemove157]

You are dry and I like. I subscribed. Good vid.

[@patrickfarley8036]

I'll have to try a spool gun before offering an opinion on preference but, aside from quickly laying down ugly beads compared to using a Tig torch and filler rods I don't really see a great advantage. You can't get into tight spots, you still need to keep the wind from blowing your argon away; the gun is an additional equipment purchase as well as more spools of filler to buy and keep on hand. Pound for pound the little spools are the most expensive so you're wrapping up even more money in wire plus now, storing it until you need it. Maybe if it was flux cored I could see a great advantage for welding in the field! As I say, I really need to try it before I make a judgement call but the obvious evidence doesn't make me feel like I gotta have it! Thanks very much for the demo video though. It certainly was worth the time to watch it!!! ✌️

[@toreewilliver8350]

The things I’ve seen for the fisheye and spool gun is to go off half cocked on the trigger to let the argon stay with the puddle to keep the atmosphere out of it.

I'd really like to see you make that Aluminum gun cabinet. Hahaha

[@ART-bg7er]

Awesome!!!!! 👏

[@abcertweld]

Spoolgun with a flex tip is great for truck bodies. For thin stuff tig. But for thick use spoolgun. I always weld down hill so the argon covers the welding material. Most don't like aluminum welding because you have to move faster. They key is the aluminum should look polished after welding, if it is dull or any black check your setting and process, because that means you will most likely have Porosity in your weld. Been aluminum welding with spoolguns for decades. By down hill you are almost 90° to the joint.

[@seandrake7534]

Bob how far should you weld say on a 3/16" sheet of aluminum before you stop to keep from warping the material Should you make short stich welds or would it be ok to just make one long run several feet with the spool gun

[@jdirt1982]

I just got a spool gun for my millermatic 212. Just need a argon tank and a new saw 😍 pretty fuckin excited!!!!

[@randydaniel964]

At the end of the weld you need to pause for about a 1 count to fill the stop so the weld won't crack. The start and stop are the most important. Pre-heat if needed but be careful, aluminum turns to powder real quick with to much of it. Other then that good weld brother.. keep helping build America 1 weld at a time!!!!!!!

[@thatguythatdoesstuff7448]

Could you run the spool gun through the weld for productivity and just go back and massage that in with AC TIG?

[@felixvillalon8909]

Hi bob. That sound is because maybe the wire speed is too high for the voltage. Go down in speed wire and keep the voltage
