I love how you "have to repair" welds that are better than 90% of what I lay down...
Jack Dawg I was there man. You’ll get tired of grinding out welds and that will make you a better grinder. I always say, the grinder made me the welder I am today.
Peter Vendere that’s actually pretty sound advice, thanks sir!
@@petervendere3451 Lifting weights is the WORST type of exercise for control. Go do calisthenics rather where majority of your exercises are stability based exercises. Don't believe me ? Go and do a free standing handstand and compare vs a gymnast, check whom has more stability.
Better than 100% of mine lol
The first step in being good at something is being a beginner.
I like how you guys are doing videos on welding related topics that are not directly welding. like that's what most people struggle with I think starting out. not knowing things like this. there's some people that are all like oh just carbon arc. which is cool if you got that but most People watching this channel are here to learn and more than likely don't have carbon arc on them all the time. its nice knowing the side skills that come with the welding.
Total beginner here. This video was probably the most valuable one I’ve watched yet. I’m just doing small flux core projects in my garage and this channel has been very informative.
Seen too many people trying to use a thin cut-off wheel for grinding (until the wheel explodes) - better to use an abrasive designed for grinding on edge! Great content!
They sell rounded edge flapping wheels that work amazing
Yeh too bad they cost so much no shop will ever buy them, they are cool though.
You showed me the best way to repair a bad weld and I'll be definitely using this when I have to repair a bad weld thumbs up.
non-welder here....love the channel! Y’all have really sparked an interest in me to learn how to weld! Am hoping to get into a local tech college just for home & recreational projects.
btw....what happened to Bob Moffet? He called once and never called back.
I didn't see the best way to repair your weld... *A rattle can of paint!*
Grinder and paint make me the welder I ain't.
I too am a weld hiding expert!
.... and a bag of dremel bits
@Dennis Young I'm right there with you, but since it's pferd showing their awesome toys...
I figured I'd give the people who like taking my money to save me my time a little jab.
I have this situation daily! 1st I usually put my grinder back in the tool box. 2nd I get the air line and carbon arc gouge.. all fixed in 2 seconds with 1/4" rod. If its sheet metal. Hypertherm plasma gouge.. I gouge steel,stainless and aluminum.. 10 times faster than grinding.
Same here brother!! Air arc is my go to for repairs.. I work with heavy plate most of the time and grinding is most of the time not the option i choose.. grinding is for when a guy is done gouging
I appreciate the the guys knowledge on abrasives but the repeating what has already been explained is unnecessary.
What did he repeat? He explained three different situations..
?
Even if he did, it’s nice to have it driven in well to remember. A lot of us visual learners like it 😂
Good instruction on something most would probably not think too much of.
ken homeier thanks man.
I've done my fair share of grinding and I have to admit, I didn't know that some (most?) thick grinding wheels were not meant for edge grinding. "The more you know!"
Apparently wheels are labelled for correct angle now (max-speed markings have been on grinder wheels for a long time, to remind you not to put a big wheel on a smaller-than-intended grinder).
James Lerch don’t feel bad. It took me a long time to figure this out myself.
Does it grind when you use it ??
Then it's a damn grinding wheel 🤣 these guys
Interesting, did not know there were different types of wheels for this sort of thing, thought a whhel is a wheel 😁👍great vid. 😁
As they noted, there was a video on this about a year ago. The catch was that the sales rep was hawking some pretty expensive abrasives.
right tool for the job, right? you can make a Philips driver bit fit into Posidriv screws and vice versa, but you're likely to mess up the screw head, the bit, or both. But if you have a Philips bit in Philips screws, you can go hundreds of screws before pooching the head, instead of maybe a couple of dozen, and the same with Posidriv bits in Posidriv screws. 'Good enough' might not be good enough--save that thought for out in the field with no other choice.
Same with your grinder wheels. right wheel makes the job better. also, if you're using a cut wheel, it's most likely a type 1 wheel, OSHA in the US (and equivalent organizations in Canada) want you to use a Type 1 ferrule and a double-sided guard. (honestly, I didn't know there WERE Type 1 ferrules and double-sided 'Type 1' guards until it came up in a recent video. And my 4.5 inch grinder came with a cutwheel, not a 1/4 inch wheel >.> )
Thank you John for the great tips
I have found that you can take 2 or even 3 of the 045 cut off wheels and stack them together on your grinder and now you have doubled or tripled the span it will cut
Cool idea lmfao
I’ve stacked two of the .045 cutoff wheels on my grinder before in a pinch! Worked good but probably not the safest!
Special thanks to Mr. John!
Was hoping that he would Introduce an ¼" Gringing Wheel with a 90° Angled at a 45° Angled Bevel as a "Not Seen/Unknown" Tool!
Holding the Grinder at a 15° Angle makes sence for a Speedy yet Desirable Removal!
I am learning SO MUCH to "Prepare Myself" to start using my 125Amp HFT Flux Core by June... As I have to clean & organize my Garage first! 😋🛠
Thanks again for the Grinder Safety Video! I'm now looking for a "Secondary" Grinder, so that Im not having to change Wheels so often.😎
Take care,

TK Skagen I use the harbour freight drill master for my extra grinder I use it with a wire wheel casue I don't need a ton of power for it
Dewalt makes one
cant go wrong with Dewalt grinders. I use 3 sizes and they are all a WORKHORSE!!
Thank you very many. I had no clue, I thought that one just was a thinner grinding disc they could keep because as anyone know, thicker last longer :D
I want that angle finder... but I can't find it online! 😅 great video as usual, fellas!
Thanks for showing us how its done 👍
Juan Lagarde you’re welcome. Thanks for watching.
GREAT INFO - I WILL USE IT
Interesting.
Flap discs have been my go to to remove mill scale, rust, paint whatever.
I guess I should try the 1/4" hard rock.
Good explanation, noticed in an abrasive catalog Norton Bluefire discs seem to allow flat and edge grinding. Any experience using them or something like it to clean out bad weld and start over?
Interesting wheel..
I have just stacked the cut wheels in the past.
You do know that there is a flap wheel that has been designed with a rounded edge. It was made for use with fillet welds. It is made by Diablo.
Samuel Swearingen Pferd also makes one. Most companies won’t buy them though.
@@GodslilRedneck23 Of course we won't buy them - they're gold-coated (expensive).
“But you need to grind”.
John 2020.
Great video tjanks to both of you gentleman
Great video thanks for the information very useful. 👍👍👍
This is another great product that I’ll never find at my local welding suppliers.
Mark Proulx you can get all of Pferd’s wheels on Amazon.
Yeah no kidding haven't been able to find a store that carries them
3m and Walter both make these wheels as well. Usually called pipefitter or pipeline wheels. Every welding or fastener supply store in the world should have them
Boss only believed in 1/4 grinding wheels or cut off wheels. Couldn't get him to try these out. Had to carbon arc several yards of welds for back gouging. I would grab any 1/4 inch disc's the guys threw out because they were small and use them on to clean up the gouge. They would go quickly but worked well. Couldn't find any used disc's at the end of the job
That was a LOT of words,,,
Thats a salesman pitch for ya
How do you see what your cutting with a cut off wheel. I am having trouble staying on my line.
Also Im trying to keep the wheel so im not in line with it. I have exploded about 4 wheels. So im gun shy now
Nice work Vanna White
Interesting, a concrete disc for mill scale, I'm gonna get one !
Good stuff , guys
Thanx
should you be using a #27 guard instead of a #1 guard?
Great video
what kind of gloves are you using when you're grinding , the black one ?
Good info but how can you grind a bad weld out of an inside corner. A 4.5 inch wheel won't let you get very close in the corner. Is there another suggestion for tight areas like this? Thanks, guys. Great info, great videos!
Die grinder maybe? With a ball end carbide
That's exactly how I do it John 👍👍
Awesome videos, the grinding safety bits is the best, keep up the great work.
One quick question, can you put up a link to the edge grinding 1/8" wheels? I couldn't find any. Again, awesome stuff!
I'd love links to all the Pferd stuff in the Pferd videos. I searched for those silicon grinding disks from the older video and couldn't find them.
Link is in the description
@@Welddotcom Awesome! Thanks.
@@Welddotcom The description shows several grinding wheels but your guest referred to a specific 1/8" thick edge usable grinding wheel, the description doesn't have a link to a 1/8" thick wheel. It only has 0.040", a 1/4", and a flapper wheel. I didn't realize I shouldn't be using the edge on these other wheels and therefore very interested in using the proper wheel. Did I miss something?
Pretty new to the channel but I remember seeing John from some older videos, man he has lost the weight, he’s half the man he used to be lol!
jcnpresser he recently retired so he’s not traveling as much. Traveling is horrible on the body. He’s still got a great personality though.
Great video. Great information thanks
Grinder and Paint :)
...make the welder i aint
Wrinkle paint if it's a bad welding day!
The problem when buying grinding disks is that there are so many manufacturers making so many types, and levels of disks. They all claim that their material, processing, backing, etc. is best. Since they’re all somewhat different, even in the same category, it’s often impossible to make a really informed decision. I’d like to be able to try a number myself, but often, you can only buy a 5 to 10 pack, with some of these disks costing $5 or more each, even in the pack price, making it expensive if you decide that it really isn’t what you want. Doing that once may be ok, but 3, 4, 5 or more times? Forget it. So you just use what you have.
Mel Gross I’ve had good luck contacting companies directly and getting free samples.
When I was working, I could do that. But I’m retired, so it’s not as easy.
Parts master slash and grind is bad ass for this kind of application
13:30 Concrete 1/4 Grinding wheel. Kool
i like their cc grind wheel, cuts sooo fast.
Use a pollafan flap disk its like a flap disk but it has a edge you can use
Based on answers below, IS there a consistent marking or labeling system that all manufs use about what each wheel is designed for ?
"Don't use a cutoff wheel, use this (larger) cutoff wheel."
Great info. Now we should use better our equipment. In a previous video with Bob Moffatt they also talked about slower speed. They used a variable speed angle grinder, which seem harder to get. Can you throw some links to that brnd/model of a grinder? Thank you all.
Eduardo Rosales A only variable speed grinder I know of is metabo
Maybe I missed something with your protractor. You’re looking for 37.5°, I read the protractor to be at 53°?
So... what's 53 + 37?
It's 37.5 off the leading edge, not the top.
Henry Ruzakowski the angle was pulled from a 90° corner so you’d subtract 52.5 from the 90 and get 37.5°.
? I am getting ready to do a smoker should I use a 55 gallon drum and what should I do thank you
First you want to make sure of the previous contents. If it ever held anything flammable, don’t use it. If it held anything else, fill it with water while you make the initial cuts. All the way with water.
Great video--very educational!
Wondered why they made a wide cut off wheel after buying one and trying to use it as a cut off wheel!!
I use 4 1/2" 40gt Steel Demon corner-edge flap disc type 29 conical design from Casa Depot.
Are all 1/8 inch wheels made for on edge grinding?
No, you need to have a disk made for dual purpose. I believe all 1/8" wheels can go on edge, but not all can be used flat.
@@Welddotcom thank you.. great channel by the way.
Why is it my grinders let me pinch 4 cut off disks together into one larger edge cutting wheel and your dont? Sometimes I only want to pinch 2 or 3 cut off disks together into one.
Make a video about wire wheels and cups.
good video.
Awesome. He didn't answer his phone and bet on horses this time.
Great info . Thnx
I had problems with flap Wheels contaminating especially on stainless
Bob Herforth I write mild steel on the back of the disks and store them in another area. I do stainless 99% of the time and know the fatal mistake of cross contamination. A horrible mistake to make and very expensive. Shouldn’t even grind mild steel in the same area as stainless.
@@carbonunit6573 That is very true! Grinding dust gets EVERYWHERE! I keep my stainless stuff in a different box.
Redbeard did a recent video on 'how to use these disks'. He specified that you should never use a flapdisk for both regular steel and stainless steel (well, he said stainless, but I'm pretty sure they don't do 'stainless' in other standard alloy types people use) because when you use a flapdisc on steel, it gets impregnated with iron particles. Used the disk on steel? write 'steel' on it. Used it on stainless? write 'stainless' on it. and don't mix them up.
Worst weld ever !! Oh that's right !! I'm grinding that crap that out all the time !!!! Another great vid !!Thanks
What heat sheild do you use
Is is possible to stack multiple cutoff wheels on the grinder to effectively get a thicker cutoff wheel? I've seen people stack them on Dremel tools, but is it safe to do on an angle grinder?
No.
That's a big no.
You shouldn't stack them on a Dremel tool either. people who try using multiple discs on an angle grinder get less-than-satisfactory results and you have a MUCH higher chance of wheel failure and damage to the grinder's motor (aka 'letting out the magic smoke').
People try it, because they see woodworkers use DADO sets on tablesaws, but they forget three things. wood is SOFT, steel is much tougher than abrasive wheels when it's not getting abraded, and tablesaws that can accept a DADO set have a much heavier motor than ones that can't, and no one makes a multi-disc angle grinder. the end result of using multiple cutoff wheels together usually involves guard failure and both wheels shattering all over the place.
I've got those one-eighth-inch wheels, but they're just too damned slow to work with. I found it best to just slog in hard with the hard rock wheel - no muckin around..!!!
Defiantly trying a concrete disc.
Does AWS allow this? Carbon arc it out.
offshorebear yes as long as the final weld meets the acceptance criteria for the code you are welding to.
What's the item number for the 1/8" grinding wheel? Thanks.
Here is the listing on Amazon: amzn.to/2vAx2At
Thanks. 👍🏼
Hey Redbeard, could you please tell us where you get your shirts from? Thanks, and take care.

Even their bad welds look better than my best
Dear world, there are gouging disks available thicker thin an 1/8” thicker. They will last longer and cut faster. They are also stronger, making it less likely to fly apart in your face.
It might not be the best way but i use a hard rock to grind out welds all the time at work
I have used for years a 5/32" disc works better than a 1/8" . The crater left is because you are welding just a little to hot
Looks like Jody, from Welding Tips and tricks, but some years older.
lol - I thought exactly that
i have only 3 types of disks on the field oh yea there is option 4 with only 3 disks on the field lol
Or you could just use an 1/8 inch cutting wheel, well you will because most fab shops dont like spending extra on stuff thats not the norm. Or you'll just be using the 1/4 inch that's worn in, you arent going to split it grinding out that minute amount unless you are an idiot and lean on the thing.
I have some 1/4" hard rocks that can be used on their edge and or on a 45°
Who makes them?
@@zachmosteller4681 dewalt. I have 1 without a locking nut and 2 with a locking nut. I havent used them on their edge yet so idk how well they work. I try to only buy grinding wheels that can work on a 90 or 45
What's the part number? I've never heard of any.
@@Welddotcom the model number is DW4523 for the type 27.
@@Welddotcom sorry for the kinda late reply, was knocking out 2g welds for test day
I seen this guy before.. Last time it was a salesman pitch. Can't remember where.
You all grind perpendicular to the baffle. Why not put the grinding wheel in line with the baffle. The Total surface will be much flater.
Next time just show the diagram on the wheel which shows the allowable degrees can call it good! :)
Just stack a couple of cut off wheels... No problem.
FTS, give me a die grinder.
Burrs last 5 years and only cost 3 discs worth. No stone to breathe in so less silicosis
But you have sharp splinters everywhere 🤬
There is a time an place for die grinders, but I would personally avoid them at any cost..
Hey man I have a question that hopefully someone can answer. I want to get certified for my business. I mainly tig weld aluminum. What type of certification should I be looking at getting
As a business owner, you should reach out to your local weld inspection company and develop a procedure. Since there are no prequalified aluminum procedures, you will have to develop your own. They can help you with that.

A grinder can make you the welder you ain't LOL
It goes, "Grinder and paint makes me the welder I ain't".
@@JT-tz5hp that's what it was LOL.
Never really had to use it so didn't remember exactly LOL
Cheers
@jrg10332 you're exactly right
Use the stringer bead wheel....for those….stringer beads...
I was about to get a dressing stone to shape my wheel lol
Carbide burr on a die grinder
A better tool would be an electric die grinder with a carbide burr.
I hope John is doing ok
He's doing great. He's now retired, but was in the area so we had him in to shoot some vids.
@@Welddotcom Glad to hear it!
I would have broke out my tig welder and cranked it to smooth it out.
Done that before.
Yeap!!! Maybe this is for beginners which is fine.
The weld was been pushed maybe for video purposes but usually the rule of thumb is to "pull the weld.I am a welder and I've seen worst welds and fixed them with both a cutting and grinding wheels
Good info .
@@dzrotary Hi Dan, I am a beginner trying to fix a attachment for a farm tractor. I had made a repair, ugly looking weld but 10 years later holding up ok. Now I am rebuilding this and wonder is there a way to tell if weld is good enough to hold? Or do I really need to grind away all of my welds and start over?
@@jimw6991 hello. Well .what kind of strength will the part be under? If it is light weight ,just test it until it breaks again. If it is heavy .then i would suggest to recut into a v shape as low as possible,then begin filling one tread at a time. Once filled,grind to make the parts flush. Take your time with this because if you over heat the puddle,it will go right through and make a bigger hole. Again one tread and a time and let it cool for the next tread
You should take that guard off the grinder
The number 1 way to fix a bad weld... training... the number two way... more grinding..
i asked you in another video what the difference was between flapper disk and zerk wheel cause I never heard of that phrase lol guess I knew something you didn't but you can call it whatever you want tomato tomato guess that saying don't work in print lol
a 'zirc wheel' technically means a flap disk that uses zirconium grit (the same thing they make cheap fake diamond jewelry from). but in a good part of the US it's become the generic 'flap disk' word, like how 'Kleenex' is a brand of facial tissues but everyone just calls them 'kleenex' no matter who makes them.
@@tashkiira7838 cool that makes sense thought there had to something different than just language or slang thanks for reply and info
Nice commercial.
Flap disc for beveling? Could you find a more expensive way to do it? And 5" grinder? Maate; 7" or 9" is what you use. Poor little 5" gonna shit itself real quick using it like that..
That beveling was painful to watch..... 9" grinder or a snagging cup.....
So a rep from Pferd, has just basically stated that it's ok to use a stone/ concrete disk to grind steel...... I think he's wrong
This isn’t a concrete wheel, concrete wheels typical use carborundum (silicon oxide) as n abrasive. This disk will most likely use aluminum oxide abrasive in a composite suspension.
Refer back to the "4 ways to remove millscale" video
