Dual shield is actually a trade name for ESAB flux cored gas shielded wires. The process is mistakenly called that at times. FCAW-G or Flux cored arc welding gas (shielded) is the proper name for that process, and it requires gas because the flux contains deoxidizers and elements to give the weld metal different properties based on its application. Self shielded wire is FCAW-S or flux cored arc welding self (shielded). That flux contains elements that create a gaseous shield around the puddle eliminating the need for gas. That wire appears to be a metal cored wire which I believe falls under GMAW or gas metal arc welding commonly referred to as mig. Metal cored wires generally produce little to no slag, They will leave behind some residue on the surface of the weld like was seen on the first weld.

Good explanation uncle crazy legs. What is shown here is actually a metal cored wire. It's similar to a gas-shielded (FCAW-G), in that it has "flux" powder inside and gas-shielding. But, it does not produce a slag on the weld.

I never would have thought to use straight argon on a flux core wire but wow what a difference that made good stuff man

Great presentation, you are getting relaxed and comfortable being in front of the camera, it shows, your allowing the information to just flow out and be absorbed by all easily, Great Job!!

In my experience,dual shield is a great product. It yields great strength and isn't fussy about minor rust or mill scale. My Millermatic doesn't like it. Even with knurled drive rollers. I've used it in other machines with great results.

I'm a big fan of your videos, lots of good information.

Definitely trying this on Monday. Ive been avoiding this wire because my shop wont buy 90/10 for spray and I hate chipping spatter off.

Great instructional videos, thanks.

I think the terminology got mixed up a little bit in this video. A reference to a 70T wire was made when in essence you are running a 70C wire, Big difference between flux core and metal core wires.

Mig welding with argon is a colder gas. So not much splatter but the weld puddle isn't as hot, have to keep that in mind.

At my work we run metal core in spray all day long !, 75/25 gas run hot hot hot 🥵 awesome video bob

great video very informative

I weld with metal core all day every day on 75/25 .035 I run around 26.5 ws 710 or 100% argon 26.5 ws 650 and make them flawless like they was robot welded. Metal core is wierd at first to get used to but man I love it flows so good and weld fast fast

great looking bead with the 100% argon!!! but one hell of an expensive way to making it look that good!!!!

Hi from Greece nice tips good work

Awesome bob your always polite and humble stay blessed always

Hi. Great job. Will run a .035 on 100% argon so some of my classmates can learn what to expect. Aluminum

Bob love your videos, we just did a project on a Marine exhaust system that required 70.6 wire .035 with a gas 92/8 and in position with a load of obstacles in our way witch made the Welding a total bitch but we got it done but the gas mix I found gave positive weld and almost not splatter, just something you may want to try sometime on the mig straight wire we are trying it out now with the left over gas mix for our everyday steel projects.

What is the line down the middle of the welds when you changed to pure argon gas.,

I must say that 100% argon and the 70T-1 dual shield wire makes the best looking mig weld I've ever seen on mild steel but it must be an expensive way to weld mild steel with mig?

Bob if possible could you please run a dual sheild flux core using 100% CO2. Most of them call for a 75/25 mix.

I think it's crazy anybody would ding your welds. I'd like to see theirs. In the world I live in, a good weld is one with good penetration so it won't break that looks good. From everything I've seen here, your tops!

Does the polarity need to be changed with the flux core and argon

Question would the 71T be close to same outcome?

Run the Lincoln NR 232 flux inner shield . 0.72 that is the standard for structural steel welding in California . It meets all the FEMA standards for moment connection etc.. Although there are other wires for structural steel this wire would be concerned the hardest and most challenging to run because it is not very forgiving like other welding wire . Bottom line , guys whom are learning will need to practice this quite a bit to perfect the process. Once its perfected the money starts pouring in your pocket; especially, in the structural steel welding arena .
