Out of all the welding procedures I've done, gasless flux is really underrated and gets a bad rep but with the right settings and polarity it runs like a champ. It does take time to get used to, I will say but once you get it dialed it's an amazing procedure to run and it's good when you want to weld projects revolving thin gauge metal like square tubing and despite the rumors it's pentrates metals ranging up from Qutar inch and above. Happy got to See Gasless flux being used for once
Yeah it's handy for a job I previously had repairing shipping containers outside otherwise you would chew through the gas having reg wound right up. It does take a bit of getting used to but I liked it.
I bought a little 125amp flux core welder recently just for stuff that doesn't matter too much or to use where i dont have 240v access, and to be honest, if you know whats going on welding wise, it does great. Its different and more "violent" while welding but if you look past that, a puddle is a puddle. I find myself using it quite often when i dont wanna use argon or drag the generator somewhere.
Cheap harbor freight 125 is now my go to around the farm! Lays a nice bead with good penetration and like you said, a good extension cord or a small generator and it's anywhere without a tank to lug around. Highly underrated and over looked. Technology has gotten way better over the last 25-30 years, back then they were kinda crappy and I think that's where the bad reputation came from
In practice, innershield, is an excellent process choice. Innershield provides good penetration in less than perfect condition of metal and to effectively self shield the puddle.
Would have been nice to see a picture in-between passes. Looks great! So many people don't like flux core because they can't see the penetration. I guess I have done enough stick that I can relate to flux.
Good job there Luke, FCAW takes a bit of practice, you’ve done well. If you continue doing a series of cored wire tutorials, I’d like to see a couple of things demonstrated ie , you do it with a K126 or similar torch/ hand piece. These are used in the field and also suitable for testing purposes. Next I’d like to see you diagnose some common field issues like incorrect polarity, excessive wire speed and it’s relationship to amperage, , too long/ too short stick out, the difference between ESO and CTTWD, mess about with torch angles etc. I realise that you are not doing paid “advertorials” but it looks to me like you are using NR211mp, good product and I’m not being paid to say that. Maybe eve do something with the T8 and pipeline wires..
Thank you for requesting to see all of those topics you mentioned..They are all main points that are vital to getting this process dialed in ... I'm still a student myself and those are all the areas that if you aren't made aware how to do those properly you will continue to struggle so thanks for that keen insight.. Hopefully Luke will be able to transfer that knowledge onto video and upload it to youtube the same way he did this one...
Whaaat;! Using a grinder, out here in California, as an Ironworker, we use (232) flux core, but we can’t use the grinder, but thanks for the tips, I have to re 🆙 my certs!
Hell yea bro 433!! This man won’t get away with that arc length on 232/233 out here in LA!! And your jumping to high bro you gotta slow down and keep it tight like a dike !
In need of a third tube of 5 litre gas for a small 130 amp MIG welder I bought flux-core instead and reversed the polarity inside the machine (25 year old simple machine). If one is reverting the polarity of an older/simpler machine you might need to reverse the polarity of the wire feeder as well. Mine was simple, but they can be wired differently so make sure before you buy flux-core.
Yes! The Arcreach is awsome, I just picked one up my self. Can you do a couple more about fcaw-s with the Arcreach. Possibly using wire 1/16 or bigger?
FCAW-S = Flux Core Arc Welding Self Shielded FCAW-G = Flux Core Arc Welding Gas Shielded While they are technically considered to be the same thing, they really are like two different processes. There are lots of different wires in each category for a variety of applications.
Is this a characteristic of flux-core welding? if i had this result with MAG it would have meant that i have not controlled the weld pool sufficiently.
I've done test up to 6g, an not ever used a backing plate. When did useing a backing plate become a test factor? Alway's started this test straight into the bottom of test plate's burning threw the tack, then make the transition while pushing the Weld forward, then point back down to bottom of starting point, then transition wire straight on the root walking back n forth, then at the top, run up am position straight on top of test plate the same as starting point. For me making all these transition's on test plate's, really help's when the test move into pipe Welding Test. Question, is the backing plate for beginners?
Would been nice to see the grind out, bend an break, cut up to see just how well Flux Core stand's up to, Stick/Mig Gas, Tig. Not seen a Flux Core Test plate bend an break test, or one Cut into piece's.
I'm new to MIG welding, so have lots to learn... The .30" E71T flux core wire i use is marked as single pass, but you are doing multiple passes with it. Does that mean you can use it for multiple pass or do you have a multiple pass E71T flux core wire? If it is single pass and can be used for multiple pass, is the something special i need to know to do that?
Love love you guys!... More flux core stuff... We use it allot on the east coast... and, ship yards....Getting it good sometimes can be tricky.......Esp, with diff thickness' of metal....
Love seeing that locally made in the USA Profax FC400 mig gun. Not sure if y’all know but we offer a gasless setup for this gun and our HD mig guns, that helps with the spatter buildup. Would love to see that in the next gasless video. Keep up the great work guys, y’all have amazing content.
Using a proper CTTWD, and the right settings, the inner flux core turns into the gas you need. However with too tight of an arc and high wire speed, the wire won't have time to get hot enough, and the flux will bubble in your puddle, and cause all sorts of bad issues like wormhole porosity. With .035 flux core wire, you want to keep that stickout or CTTWD about 1/2"-5/8" of an inch. With the bigger welders and thicker NR212 wire etc, you can run up to about 1.25" stickout, but that's only if you have to get into a tight corner or something.
For these tests they really shouldn’t allow people to have an elbow rest. When I’m welding up in a boom lift there’s typically no arm rest. These kids need to make sure they’re practicing with no arm rest and with both hands
What’s up man new to the channel. Do you guys have any videos on the basics of NR-232? I been looking for a while I haven’t really found any videos of the wire being ran or explained in detail.
I feel like the biggest thing is in gasless flux core is to watch the puddle closer not the pool Also why no weave on the cap? Cuz you'd have to run hotter and that'd undercut?
Looking to weld a few pieces of railroad track together for an anvil substitute. What is your recommendation for accomplishing this so it will hold and last??
I’m taking welding as my trade and I live in ga but I’m thinking of moving to Cali or Texas. This question is for anybody but is there anything I need to know. Like tips, rules, techniques, etc. In my first year of welding, I’ve done Oxyfeul Cutting, Stick, MIG (vertical, horizontal and overhead) and Flux Core (vertical, horizontal and overhead). I have very little experience with TIG, I’ve only watched my instructor do it.
The in-laws run a mechanical workshop and they do almost exclusively shielded flux core. It seems to be the new standard around here. Like wearing suspenders and a belt simultaneously, lol.
I just started going to a welding school and most folks tend to BM flux and i dont undesrtand why???? ive only done it for like 2 days and im already in love with it lol
Doing this type of test with a backing strip is child's play. Without one, I wouldn't run my voltage any higher than 20. Otherwise, you run the risk of burning a fucking hole between the test plates while attempting to lay down the root pass.
all good , how ever your settings here are for your situation , sharing that info has no bearing on others situations, also you can change and reduce heat as you continue for your pc heat is increasing , for the heat input has no where to go, as you reduce your heat in this can youll gain better control as you progress through the weldment and have less hang out on the cap as you complete the process
Does anybody know if flux core with a shield gas is considered MIG or not? That's what we called it back in my day. Because you're using an Inert Gas..

I’d rather do any test besides this one any process

So cool seeing what others would see when ur welding. When under the hood u dont realize how much sparks/light/smoke are thrown off.
In practice, innershield, is an excellent process choice. Innershield provides good penetration in less than perfect condition of metal and to effectively self shield the puddle.
I’m glad I don’t have to fill beveled 1” thick material like you’re doing here. Those ten pound spools aren’t cheap.
My first ever welding job was welding with this procedure, dont miss it one bit 😂
Would have been nice to see a picture in-between passes. Looks great! So many people don't like flux core because they can't see the penetration. I guess I have done enough stick that I can relate to flux.

What do you run it at? I test for this tomorrow
Flux core got me into welding, now doing it hurts me on a spiritual level.
I like it. We can not use grinders in our test just file and brush. Your is nice 👌

Yeah same here dude I'm trying get my 4G 1" in flux
@@jordanaguilar284 run it a little hotter 4g
If you had the machine hot enough in the right settings you don't need to grind but it take some experience that everybody can master by practicing
Wondering what diameter wire you used and its my understanding that a bead of 3/4" max is recommended for e71-t11.
Idk where you are but here we would never use e71-t11 for anything this thick. Structural is nr-232 and max single pass is 5/16.
@@jca66 I was referring to stacking beads to a max of 3/4". It's allowed. D1.1
thats what I was thinking
What happens to the backing strip? No one ever shows that, i guess grind off but is it stuck all the way?
What diameter wire were you using? I watched the video and read the comments but I didn't catch that
0.035

great vid. I would have liked to hear what the wire diameter is
looks better than I would’ve thought .
I always have trouble seeing my puddle when I run E71T-11, because of the smoke. Is there anything that can be done to improve the situation?
Yes negative pressure help a lot to dissipate the smoke and you can see the weldpodle more clearly
@@alkohall4185 Yeah use a fan on a lower setting, not so high that you get porosity, but high enough to clear some of the smoke away.
Use a fan pointed backwards to pull the smoke away never point the fan at your weld you'll almost always get porosity.

@@doalex2085 232 would be very interesting to see on a root pass lol

Excuse my ignorance. Isn't Flux core always gasless?
You can run gas with it. It’s called dual shield flux core.
There is two kinds:
Dual Shield - with gas
Shelf Shielding - no gas
they also have dual shield wire.
FCAW-S = Flux Core Arc Welding Self Shielded
FCAW-G = Flux Core Arc Welding Gas Shielded
While they are technically considered to be the same thing, they really are like two different processes. There are lots of different wires in each category for a variety of applications.

Ya I thought about that too
U could always tack a rest to the lift.
What I was told is to first master welding with an arm rest and then free hand will come easier.
I would use a magnet elbow rest or even some chain vice.
You’re also probably that guy that says they should use a file instead of a grinder.
Right if you a welder you don’t need no arm or elbow rest real welders get comfortable without a rest
What’s up man new to the channel. Do you guys have any videos on the basics of NR-232? I been looking for a while I haven’t really found any videos of the wire being ran or explained in detail.
Lincoln electric has the best video on 232 and 233

Electrode Negative, I think.
@@dennisyoung4631 yep...dc-
good job and looks comfortable, something to try!!!! 👏👍👍👍👍
I am a diy flux core guy and if you use best welds nozzle dip your wire and weld will run hotter and cleaner.
So with gasless do u not push or angle up on vertical like u would with most other processes?
If you pull with mig you get deeper penetration.
Is the wire speed 22,3mm/second and the ampere 123?
Man that dude knows his shit
I feel like the biggest thing is in gasless flux core is to watch the puddle closer not the pool
Also why no weave on the cap? Cuz you'd have to run hotter and that'd undercut?
I'm surprised that you didn't put a land on the bevel
thanks for sharing this knowledge your video is amazing and useful.
I wonder what the speed difference is between this Flux test vs Stick for this test?
Stick would be slower
Really good, interesting and well explained, thanks 👍
Mike , England
Gladstone laboratories in Cincinnati ohio did all our bending and x-raying. For weld certificate.

Nice job. Would clean the buildup around the nozzle.
Great info!
Really appreciate your video ☺️
How is it you’re using a grinder. I’m a union ironworker and the only cleanup tools we were aloud to use were the slag ax and a wire brush.
what was the hood he was using? big fan

Does fluxcore put out harmful fumes?
Yes

The teacher forgot 2 turn the gas on during Mig class an kept telling us we were all doing something wrong, turned out he was in the wrong.
and you guys didn't figure it out? Maybe you were in the wrong
great video, but was that cap under 1/8 of inch >.>
can you go up hill or down hill in this test
And why run a cup if it is self shielded
Penetration
Because if u dont have the cup itll burn the tip up if ur not careful especially if u get too close but u want to have enough to control that puddle

can we talk about where companies use these weld process applications? i never see gasless?

Good job man.
The shipyard I work at has banned gasless mig which makes me sad.
Doing this type of test with a backing strip is child's play.
Without one, I wouldn't run my voltage any higher than 20.
Otherwise, you run the risk of burning a fucking hole between the test plates while attempting to lay down the root pass.
CAn you put the csmara litle bit clos to the fillet in every pass...when finished de fillet ...keep close the camara and pass over slowly to see...
Actually E 71-T11 has a way better looking than E71-T8 a.k.a. NR 232 but can't be use in Structural purposes
Is using that like stick welding?
Yes
I run that heat and speed and blow through immediately. 18.5&125
I thought you couldn't grind your root for it to qualify, at least with the CWI's I have certed with haven't allowed grinding on root or covers.
Exelente trabajo 💪😎
What wire is this?
I use DSFCAW all the time. I would really hate the slow travel speed of this process.
Hello sir i am from India.. Nice
why use the nozzle with no gas? NM, took it off.
all good , how ever your settings here are for your situation , sharing that info has no bearing on others situations, also you can change and reduce heat as you continue for your pc heat is increasing , for the heat input has no where to go, as you reduce your heat in this can youll gain better control as you progress through the weldment and have less hang out on the cap as you complete the process
Does anybody know if flux core with a shield gas is considered MIG or not? That's what we called it back in my day. Because you're using an Inert Gas..
It’s called dual shielded welding
It’s actually called gas shielded flux core, dual shield is a trade name of esab.
Most hobby flux core wires are E71T-GS, not E71T-11. E71T-GS is not rated for multi-pass.

Fail for sure. Those weaves definitely left inclusions.
I'm sorry, my friend, I want to ask, is there a brand name MIKATSU MIG welding machine, good Ati or not, thank you, friend, I hope you can tell me, TQ
Jesus died and rose for us . He loves u !! We should live and obey Him !! (your choice) .
