Lincoln Makes the best wire PERIOD! They sell innershield now at Lowes!

Hello everybody, and hello Greg, that was a very informative video! I have to confess, I really like welding with dualshield wire. That is for two reaeons: 1st you can run hot setting out of position and 2nd the weld depostlited with my particular wire is stronger than the standard SG2 or SG3 solidwire. To be honest, my "everyday machine" is not what we are talking about in this video - it is easily able to put out 400+ Amps and so I'm using sprayarc very often, depending on the thickness of the material and position. But I have a small, cheap multiprocess machine, capable of 160Amps and it also benefits from the dualshield wire. With this it is able to spray with 82/18 Gas (which we commonly use here). This brings me to my point: it depends on the type of wire if it is suitable or not, not only on the wire diameter. There are 3 main types of dualshield wires out there: rutile, basic and metal cored. As an rough overview rutile is for out of position, metal cored for high deposition and basic for higher strength/higher alloyed steel. Besides this there are numberous different alloy compositions for each type. I don't know which that "blue demon" is, but it is not comparable to the esab filarc 6113 or 6138 and elga Stein MEGAFIL 713r that I use in 1mm and 1.2mm. These dig deep and wet out very well - even on the small machine (ok there is no chance that the 1,2mm will work on the small machine). I learned about the physics behind dualshield wire this way: because the wire is hollow, it has a higher specific energy in the contact area because this is signifficantly smaller then solidwire with the same diameter. The flux in basic and rutile wires "Cook" out any impurities and flush them into the slag. The slag also helps to stabilize and protected the weldpool while solidifying. If I would do a cut'n'etch on welds with this wire, would that be interresting to you, greg?

My dude, its highly interesting to me🤗. I think the root fusion is accept for a 2F weld. There is not a ton of depth of fusion but again, I think its ok. Based off of AWS codes and literature and my bias in inspections. I was a NDT guy for a long time. I am not a welder but I can weld up to several code standards. I really enjoy using .045 DS. But its only going to get that deeper depth of root fusion in the 3F and 4F positions. I think Greg is great and his videos are dope. I just have a slight difference in opinion in the conclusion. But thats ok as well. So I dont know how you would want to share that cut and etch. But I think it would be rad. I can only run .045 in my machine. At some point I will get a 330 trailblazer and suitcase. I would like to see how the bigger wires run. I cant really justify buying those machines right now. As my level of side work is not that big, but I can work up to it 😅.

​@@blueweld75 as soon as Position allows to spray it will get good root fusion. 1g,1f,2f work great. 3g&f uphill with some limitations 4g and 4f I had some bad results testing. With shortcircuit no problems in all positions, you can weld vertical up with no manipulation of the mig gun. Open roots are guite easy with a ceramics backing. For saying: I'm no welder. I learned it initially from my father and welded kind of "redneck" for many years on farm equipment. With learning from Gregs outstanding videos and later the guidance of some educated welders my skills improved, at least it feels like they do. There is no criticism to Gregs Videos for which I'm very grateful. I'm just sharing my experience with the wires I use.

YESSS!!! Just started watching....but I've been waiting for THIS exact video! Update: Well...... I'm surprised. To hear most of the others that use dualshield, they rave about the penetration, weld quality, and increased productivity. Thanks for all of your work/effort and for making another excellent video Greg!

The biggest thing I have heard is dual shield being a big penetrator. I know even bigger wire can get good penetration, but the .035 and .045 wires seem very limited. No doubt the .045 is starting to see some penetration but in no way should a person attempt to use .035 or .045 dual shield on stuff like 3/8th plate with a 200a home hobby type welder. So many people on the internet said dual shield was the solution to poor performance on thicker steel with a sub 210a machine. After the ton of testing I have done I am going to say that’s a definite no go lol.

​@makingmistakeswithgreg that's why I love this channel. You don't just accept what is said, you test it

I find that dual shield .035 is really good for applications subject to a lot of vibration. We use it for trailer builds where it seems to have better elongation properties and is more resistant to stress fractures with cyclical loading. The penetration is adequate for the cladding but we stick to .045 or .063 DS for the structural elements or just run 7018 or 7024 depending on position.

I definitely did a ton of tests and at the end of the day my takeaway is if you have 26v and 220+ amp machine that can run .045 wire, you could probably weld a bunch of 3/16 to 1/4 steel to ok results. I wish it just had more punch. The beads sure look nice though lol.

@blueweld75

Yeah, dude your video was great and I digged it very much. I just have a different conclusion than you do. Great video and great reasoning as well. I just think based of off AWS codes and literature , that you just need root fusion and not necessarily beyond it. Like how spray goes way beyond the root. So there is an argument for depth of fusion but like you said, its like 7018. And I am ok with both, as long as there is fusion. I also have a bias cuz I have seen and inspected some gnarly things built with .045 dual shield. And some of those bits where welded in the 2F. More and more home 200amp machines can weld to 24-26 volts and they are affordable . I really enjoy using 24-25 volts for dual shield anyway. I want a smaller weld size in one pass for my welding style. The punch in the root really happens in the vertical and overhead positions, with this wire. I was surprised though about the 100 co2. I thought it was going to be bigger. Again great video and good reasonings for your conclusions my dude.You never steer anyone wrong. And you make videos like how I do on IG. So I have no problem using you as a source for folks like I do with welding tips and tricks and weld.com . Keep crushing it dude.

Good information. My tinkering got a step up.

I use the Esab 7100 dual shield in 035 and 045. works just fine with me. Some use the Select Arc brand and say it works just fine. I think you need to try either the Lincoln or the Esab dual shields as this is what industry uses .

I will definitely do that. If it turns out blue demon just isn’t much good it will be a surprise. I could believe it though lol.

I love the video's but I think the issue is the wire you are running, I use .035 Lincoln Outershield 71M, 75/25 gas, it penetrates deep just like normal spray transfer but can run at lower voltage, I run this with a miller Multimatic 200, from a miller engine drive, it penetrates enough it will burn through 1/4" with mill scale easily, I can see the arc cutting into fresh metal. I also use .045 Outershield with a suitcase and it has never let me down yet, I do repair work on logging equipment, I have not had anyone call me back and say it broke. I need to run some .035 Outershield and see how deeply it does penetrate with my configuration, I have done bend tests and it has enough elongation it doesnt show any signs of giving up by bending a coupon into a horseshoe With the .035 lincoln Outershield, I run 25V and 450 IPM per the lincoln weld setting app informaton, It runs well and it is rated to weld 1/4 inch and up to 3/8 inch according to Lincoln.

@@makingmistakeswithgregI concur I use Lincoln 71M as well. My settings on 3/8 plate is 24.3-24.5 and 415” per minute 35 to 40 cfh of c25 gas. Very strong welds. I tested with a 6” fillet put a 36” handle pipe wrench (scientific I know) couldn’t even bend it. Duplicated result with kiswell, an off brand Korean wire, only difference is it broke my vice on that one.

Lincoln has a UltraCore (aka Dual Shield) 0.045” 71a75 on a 15 pound plastic spool. I have seen mostly 10/11 pound or 33 pound spools, but never a 15 pound 😮 spool! I’m guessing it’s about the size of a 10 pound spool but wound differently (slightly wider spool with a slightly smaller hub maybe?) to accommodate the extra 5 pounds. Most 200 amp class Homegammer MIG welders have adapters for 10 pound spools. Would a 15 pound spool work in our machines? Perhaps one of your many viewers can enlighten us?

For us diy guys, if we were to limit material thickness to 5/16” or less (most likely 1/8” to 1/4” thick), do you think Dual Shield is viable? I found 2 pound spools of 0.035” dual shield by WeldingCity E71T-1 for $18 on Amazon, and of course there is the much larger 11 pound Blue Demon that you were demonstrating. It sounded to me like you implied the 0.045 wire was by ESAB? During my research, I found out that sometimes in wire designation there is a clue as to which cover gas the wire was designed to be used with as follows: if there is a letter that occurs in the designator e.g. E71T-1C it’s designed for C100 if the letter is an M (E71T-1M) it was designed for Mixed C25 and if there is no letter, it is unspecified. Sometimes depending on the manufacturer, it is a combo like E71T-1C/1M I think it is worth testing on my Miller 215 (running on 240vac can produce 27v @ 600 ipm), but not sure if I should get some C100 and a spool adapter for the regulator. Not that I do heavy duty welds with any liabilities, but it would be interesting to use it on some projects. I have inquired with another YT professional welder who says the Miller Multimatic 215 & 220 can run 0.045 thru their standard whip. I understand you have access at work to a Miller 215, perhaps you could try a few welds and see if it can handle it (I am assuming it may be something you may want to use at work if it does turn out you can run either size dual shield wires). Perhaps I am mistaken, but it also looked like you were using your Miller Digital Infinity hood and oddly two different brand gloves, which I’m hoping we will get to hear how you like the hood and are testing gloves!!! I’m looking forward to hearing more a those subjects soon LoL

I bet the liner would run .045 no issue. Keep in mind if you keep it straighter it would be best, less chance of pinching the wire due to tighter fit. For 3/16th to just under 1/4 I definitely think .045 would work great. I guarantee you will find it far easier to weld with it out of position than normal mig. It makes really nice looking welds and the travel speed is very fast. Good eye on the gloves. I am finishing up some glove testing. I lost a bunch of footage when my camera was stolen so I had to rebuy some gloves that were destroyed and reshoot a lot of the video. I am also finishing up testing on the Lincoln/miller/esab shootout part 2, so I have to weld a bunch with all of the hoods. So far the miller has been exceptional.

Hey dude, I have a miller 220 ACDC and I run .045 71m Lincoln’s outershiled through it. I got the bigger liner and drive wheel for it. Just be mindful of duty cycle and pay attention to your gun dude. Guns are consumables and you can cook it. Dual shield runs really hot in comparison to the amps. I have burned through a 5lbs in a day of welding on a 10lb spool( this is a guess mind you.). And the machine and gun is fine. But my gun has been very hot. I just switch to 1/8 or 5/32 7018 and let my gun cool down, if I really need to hammer stuff. And I have used my 3ish year old machine like someone making money with it , in the heat and the cold. So I have been ruff on it.

@@blueweld75Wow Dude!!! that is some really good information! I have searched far and wide for that kind of info on running 0.045 thru the Miller 215/220 machines (according to Miller the MIG and Stick internal/electronics are the same, with the main difference being the AC TIG and a few adjustable features like Inductance). At least for now, I’m going experiment with the gun they come with, and I have a source of the proper sized tips T-M045 (for those who want to know), but I haven’t found the 0.045 roller yet. Do you have a part number for them. At least for now, I was just going to try the 0.035 knurled roller they come with. I am also trying to find a good Dual Shield wire that will fit on the hub. I know it can handle 10 pound spools, but the Lincoln 71a75 wire smallest rolls seems to be on 15 pound plastic spools. I think I would like to try to go with Lincoln and then maybe ESAB or Blue Demon if they are the only affordable options. I would really appreciate any details (part numbers etc) about the Gun Liners, Rollers, brand Wire and Shield Gas you run, and I’m sure Greg (uses Miller 215 at work) and many other folks would too as it seems there is virtually no info on forums or videos to be had.

And you want to be pushing your Dual Shield FYI

Hi Greg I've met "dualshield" commercially. First-off - no way do your search for "penetration" - what you seem to want is not a characteristic of this wire and is irrelevant anyway. This consumable gives reliable fusion - not melt to the other side of the Earth... In a fillet weld you want to melt to the fillet corner. Engineering design - do not rely on something which is expensive to prove - so design basis is melt to the fillet corner and not more. This consumable does not produce deep "finger-penetration" ever. What is important - the fusion is very flat / uniform - as you rightly say. This flatness of fusion probably comes from spray transfer - which you want. Getting to what's real and good about "dualshield" * runs perfectly well on 100%CO2 - big saving on shielding gas - especially in a shipyard where can have CO2 mains and turn-up the gas shield - many "shipyard" "dualshield"'s optimised to run on 100%CO2 and warning must not use Argomixes * runs in spray at all useful powers (Amps, Volts) - basically all conditions - for smooth *spatter-free* welds (spatter-free = not wasting time despattering(!)) and on that 100%CO2 shield * one welding condition for all positional welding - something like 215A and 26V - lovely vertical-up simply follow the joint, let the flux sort everything out - can do this all day 215A positional including vertical-up is some productivity positional - not going to get anywhere near that with MIG/GMAW. Makes Flux-Cored Arc Welding / "dualshield" "the one" by a large margin for a lot of commercial welding. There is a higher Amp condition for running "on the flat". 2F/PB fillet and 1F/PA butt weld fill. So you only have two welding conditions - "positional" and "flat" - both invariant volts/amps spray - so you do not need a fantasmagorical welding machine which will also play "MP3" audio music files (sarcasm here) in the tough conditions of a shipyard or big commercial cactivity. Good solid renowned workhorse machines. No pulse, no eslup, no nothing. "Just" plain constant-voltage. Voltage - set the voltage "by eye" - correct spray-cone length - short&compressed - for focussed arc. Counter-intuitively - lowest spray-arc voltage gives most assured fusion, as you are focussing your arc on the fillet corner. Vertical-up - you can also control voltage so that you "just" fill the aim bead width - might add a fraction of a volt so fills to fillet size (face, leg-length) in a "natural" straight-run pass. Reiterating: * sweet on 100%CO2 * "spray" at every applicable welding condition * reliable fusion regardless of that fusion being modest * excellent positional welding * only two welding conditions for all jobs * optimal welding machine is the simplest & most robust

Forgive my ignorance but... what is spray arc?

What is dual shield used for? Based on your video is doesn't seem to have a use.

@blueweld75

12 күн бұрын

Dual shield is used where you need high deposition of welding. And you need properties that make the weld hold up to a ton of stresses. And it has even really good properties in colder environments where things would become brittle. You might consider using this wire if you have an older machine without pulse for hard wire. So you can use an cheaper industrial machine and weld out of position with it. Thats because of the wire. So think fabrication shops. Like in ship building. You might be in a really tight hole way down in the ship. And you can set the .045 wire for something like 25V and 275-300 WFS and weld in ever position. And you can just keep putting in a ton of metal because its a wire fed process. Fluxcore gas shield wire was design for out of position welding . So vertical and overhead, thats where it punches into the root because of the fast freezing effects of the wire. But its never going to have a bunch of depth of fusion in position welding. I believe that the depth of fusion is adequate hitting the root in a 2F like in Greg’s video. You will also see Dual shield in bridge welding shops , pipe and pressure vessels shops, and even folks who build trailers at times. Dual shield has fantastic elongation, and Tensile properties. So it holds up really well to vibration and being pulled on. So think like big boy trailer with a big construction machine on it or like a bridge . Its not the best for outside welding due to the shielding gas . But its used everyday outside in tank building , ship building, construction machine repairs, and also bridge and buildings.

How come dual-shield can spray with C25 or C100?

@makingmistakeswithgreg

So the hollow tube doesn’t take nearly the amperage to become liquid as it leaves the contact tip. That combined with the additives in the flux allow it to basically hit spray in situations where normal hardwire wouldn’t be. At lower settings it might operate like a globular transfer, but using suggested settings it is definately a liquid and not a solid wire.
