Gas shielded flux cored welding (sometimes referred to as "dual shield") is a topic that we've had lots of requests for lately. Before we get into various testing videos where we will dive deep into technique and different applications, we are going to introduce everyone to the basics. This video should give you an idea of what settings on your machine will do to your weld bead.
FCAW is no different than TIG, MIG and Stick when it comes to practicing. The first thing that you will want to do is to run as many straight line beads as you can. Run straight lines until you can't screw it up, then run some more.

He is like the Bob Ross of welding. Just so great and relaxing to watch him and you learn a ton. 👍👍👍
I agree
Not sure if you know but he used to teach welding at a college
Happy little beads. Lets get rid of this slag, lets watch it fall clean off and then we will fill in with some more happy little beads.
Great comparison. Agreed.
His bad welds look better than my good welds. Guess that's why I'm watching this.
In the late 70's Lincoln was developing the flux core for pipeline welding. The company I worked for , of about 3,000 people, selected me to run welding procedure for Lincoln in the field for welding high pressure gas pipeline from 0.125" wall thickness to 0.500" wall thickness. The wire at that time would to toe nail a lot. Toe nail phrase means it was not stable it would burn to one side and switch back to the other. We did get a procedure made to meet API 1104 pipeline welding code, the welds were x-rayed and mechanically tested per API 1104 code and passed the requirements.
TIP
When welding a 30 degree V grove butt weld, the filler pass prior to the cap pass or final pass leave the prior pass below the surface about a 1/32" this allow syou to see the weld grove and allows you to make a nice weld cap or finish pass. If you do not do this you will NOT be able to see where your weld path is. This holds true for GMAW as well.
I have worked as a welder in Finland for about 10 years and I have worked in about 10 different companies. We have never really used anything else than flux core for general welding. It's just so much faster and easier .
With or without gas?
@@stephentyas4698 With gas. In the companies I've worked/trained at it is mainly dual shield welding. If not it's tig/stick. Just so much nicer.
I just started as a weld school trainee where I'm at...and learning about this is amazing...not really much for me to learn here as my flats are almost perfect....my vertical welds are so crappy.
@@grekygrek From my experience you do NOT need to manipulate the weld in vertical position, just go straight!
@@TheSongou yeah thats what I'm sayin lol there's not much here for me to learn just need to stay under the hood and practice
Bob, your one of the prettiest welders I've seen. ( your welds I'm talking about).
Go on get it out there lee. Youre diggin his goatee
I love watching these videos. I'm an old retired RN so my welding days were when I was in HS using a stick welder. I was in the 9th grade. If I could get a little FCAW unit to do little welding with.... Those were the days which I can't do now. Love watching these videos. 👍😁
I've run hundreds of spools of that wire, passed my 3g cert test with it and co2 very forgiving and very very good wire for heavy fab work in all positions.
I really appreciate the time that you put in to help teach us. I am brand new to welding; my omnipro 220 just got delivered today and I have watched hours of tutorials. I have gotten so much good information from your videos and just can't say enough how much I appreciate it. Thank you, thank you, THANK YOU!
Excellent tutorial. I’ve run a ton of dual shield on large bore pipeline over the years, and I can confirm that everything you’ve stated is exactly correct. Keep up the great work!
Bob, I have found each and every one of your videos educational bar none along with your amigos or compadres! One huge thanks for sharing your time and skills 🙏
I have learned a lot from this guy! He explains it SIMPLE!
This really helps me I’ve been running fluxcore dual shield on some structural steel in the fab shop and I’m a stick welder so not too familiar with setting the machine. This has shed some light for me and gives me options for what I need for my welding thanks-IronmanMike
I just love listening to you. Your explanations and variations to explain what you tell us, are spot on. THANKS!!!!!
I hardly ever run dual anymore but I really do miss it. It is super forgiving to me. I use hardwire a lot now but the dual is so much easier for me. Thanks Bob for spreading the info out for all the new welders or even the old ones looking to add to their game. I sure would like to come out and use some of those newer machines. All I do is on old school rigs.
Same, hardwire .52. Working on dredging vessels
I just started using Dual shield Flux Core Wire for a job welding 3/8 angle to 1/2 plate. On my ESAB Rebel 235ic, I use ESAB .045”Dual Shield ll 70T-12H4 wire. The sweet spot for this machine is 26.5/300, for flat and vertical positions. This wire does indeed run smooth with little to no spatter. Great video as always thanks for the lesson.
I'm going to be having my first try at flux core welding (First time trying ANY sort of welding) on Monday, really looking forward to it. Thank You for all the useful info!
Thanks again Bob for another excellent video!
Best explanations and welding advice hands down. Thank you sir.
This is a great video, but if I may, next time you do a flux core demo, could you use a really cheap welding box? Something like the Century 90, or one of the harbor freight 120V titanium inverter welders, perhaps a 120v forney - you get the idea, a flux-core only cheap welder. For us guys and gals that are learning this just for weekend jobs, or for welding something like a fence of exhaust pipe. I love the videos, yours are definitely the best and my goal is after years and years of welding to make my best weld look like your bad welds!
Seconded. I'm a total neophyte when it comes to this stuff. And, like most beginners, I suspect, there's very little appeal to dropping a thousand dollars plus for my first right. This is gonna be hella expensive to my mind al ready, and that WITH a cheapie setup.
That said, I suspect the only demographic that would get anything out of this sorta vid will be mostly similar, and therefore in need of a much MORE introductory lesson. You started out great... then just dropped into preparing we know what all those terms mean
Agreed, show me a beginner with a welder with so many adjustable settings. Mine literally has a switch for high/low voltage & a dial for wire speed.
This is dual shield, meaning gas and internal wire flux. Look for videos that show gasless flux core. Welding tips and tricks has one
Awesome video! Your are a great teacher thanks for the content! From just a weekend welder I appreciate it!
Had to use this on a job last week and the boss was pissed because it wasn’t pretty, hopefully next time I use it I can weld it better, thanks for the info!
ive had GREAT luck with 24V and 275 WFS. ive used that on many different machines and minimal adjustments are needed for the WFS but is works. not so much heat input and optimal control for all position welding.
i should add i have only used the Lincoln ET71 wire
Gotta say, the arc shots in this video are fantastic!
Thanks for the video !
Needed a refresher, been a lil while
Very educational. Thank you.
I am a boilermaker only ever used gas mig and stick welding.. I just took a new job whare I will be using flux core . I did find this video usefull . I have no doubt I will be able to flux core weld after running a few beads like this seems pretty straight forward.
Thanks for a great video. Just started welding and I want to try dual shield. Very informative .
Excellent thanks Bob another very instructional vid just outstanding!
Thaks for the consistent videos awesome work and so very helpful . 😎
I really enjoyed this, I would like to see this style video done with short arc.
we run this wire a lot in the shop. Love it.
Man you know you can weld. Great demonstration.
I LOVE THE WAY YOU TEACH.
Thanks for the education Bob!
Love me some flux core! Very informative too!
Such smooth welds, nice.
Great video Bob I ran this stuff a lot servicing semi trailers it’s fun stuff
WOW dual-shielded wire is so forgiving and produces such a perfect bead! 😱
this was a great learning video
I have tried dual shield with my Lincoln 210MP with .035 dual shield wire. My machine when I set it to flux core wants me to change to electrode negative, so thanks Bob for clearing that up. One thing you didn’t mention that I ran into is i had to change to a knurled drive wheel. I was able to get some results but now that I have this new info I am going to try again. One issue I did have is the wire binding at the tip and bird nesting in the drive. I am thinking with these settings and the 5/8” contact distance this may not happen as much. I am thinking the dual shield “tubular” wire is a lit softer than the solid wire, and that, with the knurled drive wheel increases the chances of this problem. Thanks for a “beginner” video for us true beginners!
Good beginners instruction.
Idk why those 45 people disliked. But that ratio of 3.5k to 45 is awesome. Weld.com is a godsend for welders of all skill levels
Great intro video. Now I know in class for butt and T welds I can adjust my voltage a little higher or lower than the Lincoln electric guide. Thanks for the video.
Very Helpful. Thanks
Love the video!
Had never heard about the correct tension. Wear an insulated glove when testing it!
Seldom mentioned is the gun tube liner, looks like a long coiled spring: hard to stuff a 0.055 wire down a 0.035 tube, and too big a tube lets the wire S-curve instead of advancing. Clean it sometimes.
You really want an auto-darkening helmet.
I love love love ESAB wire both their hard wire and dual shield FCAW wire as well.
Always fun welding flux
I learned to weld on dual shield when I was 10 by my dad, I love flux wire
Very educational learned alot thank you
I have been using flux core wire for 20 years now, built a trailer, 2 front class III hitches, heavy duty small tractor accessories, put tons of stress on the welds with pulling thousands of pounds with a winch, ripping up dirt, never had any weld break, its tough stuff. Plus I don't have to pay for gas.
Nice video, thanks
Great vid.
I run a warrior 500i all day at work. I have two settings that I use religiously, 28/400, and 24.5/350. I use 28 for any weld that isn't out of position. 24.5 is my go-to for all welds that are out of position.
Thanks, what flow rates? I'm just starting to play with dual shield and have some ESAB 710X-M .052".
@@workwillfreeyou 40cfm on 75/25. I also use a 3/4 inch hd tweeco nozzle
Great tips
Thank You!
Hey Bob, you look kind of like an Ewok from star wars there at the beginning...
But I got a roll if that select arc 730, .045, same stuff you ran here...thank you, Zack from Select Arc. I would concur that it is a very forgiving wire. It's probably the nicest dual shield wire I've ever ran too. So thanks for the video, Bob. I haven't played around too much with the settings yet, but I've used it for a couple of jobs in 3/16" steel square tube and flat plate. C25 gas at 40 cfh, started at 450 ipm and 26.5 volts, ended up turning it down to around 390 ipm, at least by calculating the dashed lines on the dial of my old MM250. Mostly in the flat position, a little uphill, most of it not quite as clean as it could've been and even a little mill scale left on. Some straight pulling, some manipulation. Runs nice. ZERO worm tracks. I like it.
Nice job mate. I've only really used solid wire with gas but im starting to do a bit of flux core at home. I would've like to see you drop the wire speed when you went down to 21.5volts as the average affordable gasless mig welder only runs around this parameter. Mine is maxed out at 24v. Great vid. Cheers
Good informative video
Great video. With our lectures moving online, I had my students watch this and write a summary of the video! Thanks!
Great video. Thanks Bob. Can you explain how to avoid worm tracks? Thanks.
thanks for sharing
Flux core was made for outside where as mig has to be in a free of environment stuff like wind per say . Mig and Tig are in a enclosed free of stuff that can mess up the weld like wind rain stuff like that. As same with all clean metal to be weld on but winds and whatnot isn't for mig or Tig. But dual protection on flux core cool . Not needed but adds more protection. Cool vid.
I love gassed flux probably my favorite process lol
Very good smoothie on that last run low wide and pretty lol
I'm 9 and have only been welding for 4 years, but I'm going to try this with my neverlast welder.
Can you do a video with 3/32nd dual shield flux core wire. Im involved with heavy plate manufacturing and would appreciate any tips always willing to learn from experienced people
I hope you provide content about 3G welding (up) and provide us with information and techniques along with the voltage, thank you, success always... From Indonesia 🇮🇩🇮🇩
Welcome back bob
Bob, can you do a video (or explain) how to select the proper MIG wire (flux core and solid) for the job? Looking at the Select-Arc product list, they have probably 50 different flux core wires to choose from, and even more solid wires. Many of the product descriptions sound the same - so which one do I pick?
Great video as expected. Question? Is dual shield wire different from flux core wire that the 110 volt gas less welders use?
Good stuff
thanks very much
Dual shield is something I really want to try with my Everlast welders. If it can deposit as much as I have been reading you can count me in.
Hey Bob, do u have any videos on D1.8 structural test? .072 flux core ?
Thanks Bob💯💪👍🇺🇸❤️
I’m just beginning to weld and After seeing the various welds in this video is there one of these four welds that is the best of the bunch ?or are all of the welds sufficient ?
Very informative! Thanks for sharing!
When my uncle was teaching me to weld he started me off with dual shield, after I started getting the hang of it he bumped me up to a spool gun on aluminum i wouldn't be as good as i am today if it wasn't for him
Great video. Im new to this (welding in general) i have the valcon 220 pro. For me it always seems the wire speed feels fast with pre settings does this mean i am going to slow ?
How was your penetration after you cranked up the voltage the 2nd time and the bead flattened out quite a bit?
Awsome, 👍👍👍
I've never heard of gas shielded flux core. I've got an everlast welder for hobby use so would this be good for me?
Hi, can you do a video on budget face shields to quality ones? And the best face shields for which welds.
I wish MORE people understand that Self & Dual shield are NOT the same thing
Thanks Bob for the video
I wish I understood the difference.
@@AnX8765 thanks. But I understand what the word "Dual" mean. After all I does has a KalimafornEa EdamaKasion. 😋
What's the difference, why use the Dual shield. One shield over the other. Why both? Will "Dual" help me get even a cleaner weld. Will I still have my slang from the FC?
Very Educational!
I just purchased a HFT 120 Flux Core Welder for "HOBBIEST NEEDS". But I have yet to take it out of the box due to insecurities of what settings and such!
For my "Hobbiest Needs", (and I have a 10# 0.035 Spool) what settings would you recommend? (Typically 10-12G Clean Steel)
Take care,

Any information on running the .045 Dual shield from a suitcase with 100% C02?
Wat sorta colts and wirefeed speed wud u run if you were horizontal or vertical up then.
Would you be willing to video a shop on combating distortion? That's where I'm struggling right now.
I'm with you, not covered much at all anywhere, what I know I've learnt the hard way but willing and wanting to learn more
Metal core applications and demo please :)
Hey Mr bob how do you burn out small inclusions of slag if traped? Without a grinder ?
Sir,if you were building a welding bed, what gage metal would you use and why?
Also what welding method would you use and why??
I'm going to have to build a bed, and I would like to know what the experts, like yourself would use to build a bed that will stand the tests of the oil and gas industry. Thank you sir for any information you can give.
Won't setting that easb on fcaw set the machine for DCEN?
Dual shield is nice for good looking welds, just it's easy to gas a weld depending on the type of weld your laying
Would you trust this method to weld a steel boat for bluewater cruising?
I love flux core. It's not bad and it gets better penetration
Please could you suggest what could cause worm hole porosity in dual shield metal Flux core welding? There are probably several I'm sure. I occasionally get it and I'm not sure what I'm doing that causes it and that it's not everytime?
Thanks
Ok question. When I use my flu core I don't have slag. Why is that running Lincoln 211
great work, and theory,HI, i need your advice, as i weld car panels, rust repair, and also, sometimes i weld 3/8" gauge or tickness,i m not a trades man, but i'm not sure, i can not seems to get good weld, i got CIG 3 in 1 MIG TIG STICK,155 amps. and i think i need a bigger amps, as when i used mig gasless, it's a night mare???, i could not adjust the voltage to suit some how, maybe i should ask some one to show how i can set it,??? wonder if you can show us a litte idea, many thanks
Is it possible to weld something that is zinc plated? What issues might I have? Just bought my first welder and I'm teaching myself so I apologize if this is a rookie question. But any advice would be greatly appreciated, thank you.
What's a good amp and volts to set it up on the machine
