Guys - this Bohler wire is copper in color but it is definitely a flux core wire!
Here is the data sheet. www.voestalpine.com/welding/content/download/13516/287265/file/BW_diamondspark+52+RC_US_05-2019_Preview.pdf
Had me confused when I first watched it! Awesome things Bohler is doing with this wire! The tech specs are great!

Would that also be called metal core like Hobart fabcor 86r? Just curious is all
Bohler is Chinese rubbish with a German name. I will stick with Lincoln or ESAB.
Nope this is FCAW wire. Check out Weld.com’s pinned comment.
@@WTFChuk I don’t believe it Chinese made….Bohler passed more PQR’s on the first go around than a lot of other fillers I’ve used on these tests.

Get Bob Moffet,Red beard and man cub back in there please. I know Red beard can run wire.
I’m a minute in and I already disagree with the title. This is not flux core basics when the first process is dual shield. 🤦🏻♂️
what a douche...dual shield is still considered FCAW...do you even trade school?
I agree that the idea/title was FC basics, then we learn a bunch about settings on a high-end machine (my Lincoln MIG-PAC 150 has none of that..) and then there’s shield gas? Are we still in flux core basics?
And if we all were trade school grads, why are we watching a “flux core basics” video on CZcams? Perhaps clean the shit off that mirror you’re looking at and see who the real douche is in this thread.
Ok so I’m not stupid. I was like 💥 just like that ??
Just bought some flux core a few hours ago to try running gas shielded for the first time myself. Was really glad to see this video pop up. Thanks guys keep up the great educational videos.
Awesome! We hope this video helps. Remember, practice makes you better and better practice makes perfect. If you have any questions shoot them over! 👍
I WANT TO SEE HOW IT WENT!!!

I hope you bought the proper E70T -1or E71T-1 wire. Gas-less flux core (the kind found at most hardware stores/big box stores) should not be used with a shielding gas, as per Lincoln electric, just FYI.
He did pretty well for a novice in dual-shielded flux core welding. The electrode stickout was inconsistent mainly due to the fact that he chose to weld in a more awkward way by pulling the bead durectly towards his body, instead than going through it sideways.
Great to see paul getting comfortable with the camera, much more relaxed! Nice to know the machine settings but more explanations of the machine settings would be nice. Being basics I expected to see details of torch angle, work angle and stick out for the novices. Would have been good to see side by side roots, fill and cap at different voltages to compare to cold, just right and to hot. Over all good video tho guys.
Any chance of an in detail uphill mig fillet on 5mm plate please! Got a test coming up running a single pass "christmas tree" (triangles in to the root, back out to the toes and across the face) struggling to penetrate consistently in to the root of the joint. Many thanks!
We will put that on our ideas list for videos!
@@Welddotcom I second the idea. Need to know what the settings do.
always nice video man!
It's a good Flux core basic video.
Next time, please upload another position.
ill wait! 👍👍👍👍👍🔥🔥🔥🔥🔥
Thanks for the feedback!. Other positions, check! 👍
Man that machine if great for an experienced hand. I wish company's would buy machines like that
It's definitely a nice machine! I've only used it a few times in the weld.com lab but have enjoyed running it. I would like to have one in my shop! 😎
Thanks for the information on flex core welding cuz that's what I've got at home.
Thank you gentlemen great demo well explained 🤘
Thanks you videos infomation brother 👍💯👌
Thank you!👍
The slag peel is awesome.👍👍
We tried some dual shield on sch40 pipe putting on 1/2in thick flanges and some were good and some I had wormholes. It was driving me crazy until I learned to keep more gap between the torch and the weld surface. I guess I was pushing gas into the pool.
Bro, I read somewhere it said stick out should be an inch, and then I read 1/2 inch. How big do you think the gap was?
wire stickolut on dual shield is 1 to 2.5 inches depending on the wire
So I recently found out joining stainless/carbon/ whatever to aluminum is actually possible. A company called spur industries produces "adapters" through a roll welding process or something. I think it'd make a cool video if you can get some
Won’t most beginners be running flux-core without gas?
Lol I made the same comment, this is not flux core basics 🤪
Yep, same thought here. Also most beginners aren't starting out on an Everlast Lightning MTS 275.
@@TM-dh2xb fucking A. I gotta cheapo 110v for my projects
It all depends on the equipment purchased.
I would suggest a beginner run the dual shield process because at a smaller wire diameter it ends up producing one of the best quality welds without a extensive pool of knowledge.

@@dalespilker2465 Well, when you're on a budget, what's the point of dual shield? Especially when most of the stuff I do in the field is light/medium duty repair, and my rig doesnt have room for extra bottles?
For a “basics” video this was really lacking in instruction. It was basically yeah here’s some settings none of y’all have and just watch while we play with the settings.
Just tried flux core with out gas took a little time and 1/2 roll of wire , but I found if I pre heat the metal before welding it really helped . So thanks guys for your input . Cheers . :)
Thanks for the feedback. All positive input helps. Keep burning! 👍
I welded flux core dual shield for 8 years...never preheated up the material except for some parts the were 1 1/2 inches thick.
You probably need to let the pool build up before you move.
@@eduardosampoia5480I agree. Unless you’re doing a CJP or a big 1.5 inch plate, there is really no need.
On the root pass, are you moving side to side, or straight dragging? The fill and cap looked to be side to side, but I couldn’t tell on the root.
Hi. I have watched a lot of your videos for advice. I'm a beginner at welding and lately i have been doing flux core welding and when I start welding everything goes well welds are nice and everything is smooth and then after say 10 minutes or so of welding the wire seems to start stabbing or not feeding out properly while im welding and i can't work out why it does that. Any tips besides the usual and general things to do. Running 0.9mm flux core wire with 1.0mm tip.
What's the duty cycle of your welder (x minutes @ y amps)?
you shouldn't root with flux core unless its with a ceramic tile, 22v is far too cold for a fill on FCAW, your cap should never be more volts than your fill
I root with dual shield all the time and pass xrays.
Why
Dual Shielded FCAW is extremely common using ceramic backing/ steel backing and no backing. It all depends on the particular joint and procedure being welded to.
The voltage is relative and is determined by many factors. What was done in the vide worked well for them. Voltage can be adjusted throughout the joint. Depending on the WPS being used to weld a particular joint the cap can very well be ran higher than the root and fill passes. I do agree with you in a lot of respects that in a normal application with a ceramic or steel backing I will run my root at one setting adjust for my fill and then cap on a slightly colder setting than what I filled the joint at.

Dualshield fluxcore is fast, hot, smooth, and cleans up nice once you learn the process.
You need more amps and volts on that root. Also he would've gotten better penetration with straight CO2.
You're right about those amps, definitely running to cold. Thanks for the Co2 info, I'm making a list to add to the next video.
CO2 dont make better penetration. To Get better pen you need a gas that have some helium or hydrogen in it.
He seemed a little far away to me... I would dig it in there more on my machine.. and it was definitely turned down too low
@@calholli yes he was.
Why don't you use the Flux Core setting on that fancy machine...
The flux core setting was for no gas and we ran dual shield.
@@bobhigginbotham9035 The whole point in flux core is that you don't need gas. smh
@@calholli learn about welding before you embarrass yourself. Some applications call for dual shield
@@user-zz3km8nk8c Pointless.. just use solid wire if you have gas
Because they were running Dual Shield, If they were in Fluxcore mode there would not be any Gas delivery, ie it would leave the gas solenoid OFF.
Wish there was videos on the older machines like a Millermatic 225 without all the settings
Maybe I can do some of those!
I have a ton of those in my shop!
What specifically would you want to know about the machine?

Dale Spilker yep! You are the guy for this!
I do a lot of repairs on heavy machinery parts usually around 1/2” thick material. I’m really wondering on settings, body position, and torch manipulation for butt and overlapped joints
Thank you guys for the reply and also all the great content has helped a lot of us out!!
In my oppinion the machine is not that importent. Its Your volt wirefeed and wire that matter the most
Hmm? Good audio.. camera shots and close ups , clean edition
HM-HM ! Getting waaaaay better
Thanks for the feedback!
So we got to watch a guy run a couple needs, but got no real instruction..... Awesome
You mean fail to run it
@@calholli yeah . . . I've had my first fix core welder for about a week and make beads like that...
Where do I put the ground clamp on a 2x4 to stack the most dimes?
That first arc sounds cold to me
Cold indeed
Yep.. need to turn it up
Jepp
I felt the same.
Since I am a beginner, I understand the flux core part , but then what is the purpose of the shielding gas in this case? Does this wire need the gas to protect the flux?
Dual shield(gas ) keeps the air away from the flux longer to let it form a better cap, is how it's been explained to me.
Yes, except "dual shield" is a trademark name from Esab. The correct or generalized type/name for the wire being used is Gas-Shielded Flux Core (FCAW-G, the "G" is for "Gas shielded). Most professionals when they say "flux core" they really mean "gas shielded flux core" because there ain't no gas-less flux core being used out in construction sites erecting skyscrapers. It is a specific type of cored wire usually belonging to the class E70T-1 or E71T-1. On the other side of the same coin, most beginner hobbyists when they hear "flux core" they automatically assume "gas-less flux core", (FCAW-S, the "S" is for "self shielded") because that is what is sold in most hardware stores and is meant for non-critical/non-structural welding. Most gas-less flux core wires belong to the class E71T-GS or E71T-11, The "GS" is single pass, and the "11" is multi-pass capable, but even then most are limited to about 5/16" material thickness. Any thicker and the heat-quenching effect of large parts causes adverse metallurgical reactions to the weld bead possibly causing to fail. So yes, FCAW-G needs shielding gas. Some can do with 100% CO2 (E70T-1C, E71T-1C), some with C25 (E70T-1M, E71T-1M), or some with both (E70T-1C/1M, E71T-1C/1M).
Thank you for the great explanation
Oscar Sanchez Jr, BSc. Thank you, your are hired 😂
@@zod-engineering-welding Thanks for your time and knowledge.
This single comment has ten times more information than the video itself.
Confuse... was it flux core or not... you spoke of the gas mixture and the wire.
Flux core wire with shielding gas. This is a another process of flux core welding and I should have went further into detail.
What happened to 2 knob welders? I've been welding flux core and duel shield for 20 years this new stuff with the fancy settings it a little bit ridiculous.
This is not flux core. This is dual shield. And this is not instruction, this is opinion.
It's not even opinion... it's more like trial and error; emphasis on the error
But what about the aluminum flux core? I can't seem to get it to work, I don't even know why they make it.
Is there a similar video for 3G technique
I somehow missed the "do's and don'ts" ! And WHY dual shield? If you've got a gas shield, what's the point of using flux cored wire?
What's the point in using FCAW compared to what other process?
Dual Shielded FCAW is a very efficient process in completing welds above most quality standards. Dual Shield also offers extremely good penetration.
In a production environment Dual Shield is often turned to because its not as finicky as a GMAW Puls or Spray process. In the end its all about the skills of the welder.

@@MidEngineering @weld.com maybe this would be a good video..?
Dale Spilker let's do it!
I think that it would be better to run all passes on 24 volt. To high wire feed to that low volt. When you weld fluxcore you should have little spatter. And when it sounds like bacon and egg you have the mashine on the sweet spot
10-4 bacon- NOT popcorn

Bring on the Gasless Flux Core.... I've never seen it look any good...
WHAT IS THE ADVANTAGE OF USING GAS WITH FLUX CORE ?
check my reply I made to Tim Sexton's question below. :)
I would suggest changing the title of this video to "Dual Shield Welding Basics". MIG is MIG, flux core is flux core, and dual shield is dual shield. Each is its own beast.
That is the quietest fluxcore I've ever heard
Open root? Not going to back gouge? Maybe a real world application next time ?
You dont have to back gouge you can grind it to. If it is a small weld job i dont hassel whit the back gauge. I only use a grinding disk
@@ktmturbo5836 Backgouging can be accomplished by carbon arc, plasma gouging, oxygen acetylene tourch, die grinder, angle grider, etc.
Any thing that's available and yes thickness of the material.

flux core wire but your using a gas welder? whats the point?

I thought the guy was Prince Harry..i should get new prescription eye glasses
Sorry but that is not a 1G down hand. Please explain why you did this?
This is duel shield
how is this a flux core if you're using gas,
I’m one minute in and I already disagree with the guy who disagreed with the title of this video.
Why use gas with flux core wire? Thats not true FCAW. You have a setting on that machine for FCAW. 2nd. Most people that are weekend welders or do it on the side a bit aren't gonna have that expensive of a machine. I.e. blowback settings, etc. Hell, the big millers and lincolns we used in school dont have all those settings. Asking for a friend.
what happened to the metric measures?
Way too cold for that WFS! Too little gas. A little better toward the end.
Titles it “Flux core basics” then proceeds to program his $3500.00 computerized welder...
Yeah well, I don't get it. Flux core WITH shielding gas?
Starting off a basics video adjusting most machines don’t have without explaining what they mean is pretty useless.
You do not push back into the weld when using flux core
Title is WRONG..
This is dual shield NOT FLUX CORE !!!
chris hiding from me
dude gtfo
The title of this video is "Flux Core Welding Basics" WHY are you using GAS? If you are going to use GAS say that in the title.
So you call this video "Flux Core Welding Basics
" while using shielding gas and a 3 grand Lightning MTS 275.
Yeah okie, "basics." Basics would be with some 110/220 Chinesium Amazon special or a Chicago Electric from HF with flux core wire and no gas. And the first steps would just be insuring you're using electrode negative and setting up the machine, not talking about tweaking the settings for a 3 thousand dollar machine and what type of gas you are using.
Misleading title
Those numbers and setting controls don't mean anything to me, they need explanation.
this is not flux core welding...it is dual shield welding.
arc sounded like crap. either voltage or speed wrong/
Bob got no peno.
It sounds way too hot!
Fundamentals sound like for beginners. You lost me in the first 30 seconds when you started rattling off a bunch of numbers. I’ve never welded in my life. I have no clue about set up, safety and obviously technic. Where do I begin? Thank you.
Wtf? 1min in and flux core with gas? Isn't the whole point to not use gas?
This is unwatchable. Love this channel but you've driven it into the ditch. How long before you fix it? Let me know when you do and I'll try again.
This says it is for beginners. Then you fill the whole time with unexplained technical terms. No explanations in the entire video. I think you have lost touch with your objectives. And you call Red an instructor. I think he must only teach advanced classes. What a major disappointment.
Dual sheild is not the same as flux core basics. Also, anyone notice that there's been a distinct lack of ESAB machines, and a remarkable increase in Everlast machines being used? Furthermore, its nearly impossible to even listen to any of the guys on this channel now. They can barely string words together, much less form a coherent statement that is educational. Disgraceful. And you call yourselves educators.
Not really basic with that fancy machine. And why flux core if your gonna use gas?
Another NEVERLAST welding comercial how much were you paid to show this junk welder ?
The Everlast machines are a pretty good buy for the money spent. Obviously if your planning on using is 10 hours a day every day I would personally go with a Miller or Lincoln but that's only because I've never used a Everlast machine for 8-10 hours. A guy somewhat local to be buys Everlast GTAW welders exclusively and they seem to work great for him and he uses them around the clock to weld heavy aluminum.
For the record I don't get paid by Everlast but I do think they are a great entry level machine for a hobby welder or student. I steer my students towards them often just because you get so much more for your money and 9 out of 10 times they will only use it a few times a week.
