Basic Spot Welding 

Jesus man I'm more impressed with the engineering everything was thought out absolutely amazing every little detail

Proper explanation, lucid and well presented. Thank You.

I’m taking my first metalwork course in school and it’s very much welding, especially spot welding, focused. This video really helped :)

Great video, very informative! Thanks Tony

Very good video. Good instruction on how to spot weld. Thanks for the 1/8” limitation on it.

Thank you. Answered a lot of questions in 10 minutes.

Thank you for taking the time out to show everyone this.

Well done bro, thank you for your video, you give me a great idea, thank you again!!!

Great spot welding class, thanks! 🖖😎⚒

Great video Jeff, very good teaching

good video. i use spot welding often on body panels like cab corners and rockers

Thanks, that was very helpful.

Thanks man. Have a handheld spotwelder at the shop and had no idea what the damn thing did. Already hatching new ideas.

nice video, thank you for the lesson!

Ive just discovered your channel, and I subscribed instantly. Thanks for sharing your knowledge. I'm particularly helpful for your excellent ways of teaching, your descriptions, etc. Let me tell you that I learned a lot just from this video. I wish you the best in your business! Greetings from Chile

Great demonstration! tangentially related: If I were the car wash owner, I would have gotten these bottle holders fabricated entirely from cotton or some soft hydrophobic fabric. The top and bottom hems could have a stainless steel wire embedded inside to keep a cylindrical shape to accept the bottles.

Where were you when I needed you?!! Had a car owner at a car show explain at length how is car was absolutely perfect colours standard and exactly as it left the factory. He got very defensive when I pointed out his panels were fitted with tack or puddle weld in pre made holes. He was adamant they were spot welds! I tried to explain to him that spot welds are a resistance and pressure weld with no holes or any other pre preparation. He relented to claim they were the same thing! I had to explain spot welds introduce no extra material to the joint whereas puddle or spot welds does. He left a bit crest fallen but a little smarter. I bought a spot welder for discerning customer work but it ain't cheap kit! The cost of the solid copper arms is a bit eye Watering! Great video mate

Good job !!

Awesome video.

That's cool, I like what you did there ;)

Thanks for sharing!

Thanks for sharing! First time on your channel and have to say you're very very good at talking to the camera and explaining things + what you're aiming to do.

Very nice idea

Very Nice my brother 👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽

Very cool. Thanks.

Thanks,I'm from Malaysia..appriciaete it...

Very good My friend y like tks joe

Thanks for the video.. you should hold down, keep pressure for about 3 seconds after you stop delivering power so they will bond better than just lifting off..

Very useful, Thankyou sir

thanks a lot. very nice.

The spot welder would be great for making cabinets or carts etc .

you could do a vinyl dip like what pliers handles have

Good job

Decent guy decent vid great hoops

my high school metal teacher had only taught us to do a quick zap and let go. I didn't think of about holding it for couple seconds. A lot our spot weld projects would fall apart the same day or the next week.

Thanks jeff , im debating on building one or buying , i have a 3 volt 800 amp transformer

In my work place, they do spot welding and other times too. I don't need to use them or whatever but it's interesting to know stuff ay? I'm sure I'll be checking out other videos on your channel as I'm interested in all the metal work they do. Again I don't use the machines lol, I'm production chaser.

Thanks for the vid, but I'd think that you need something more than cloth tape to protect the cars, especially higher end cars. Guys washing cars tend to lean over them a lot to reach the center of say a hood or windshield so that they can dry/wipe them. Anything with exposed metal is going to scratch the car. Even getting into and out of the car quickly (which these guys also do a lot of) is going to cause something hanging off their sides to bump door panels. You might want to look into something like a rubber coating to completely cover them especially since cloth tape tends to come off in water, as well as having a slightly abrasive finish.

I’ve got both a 120 volt and a 220 volt spot welder. I bought the Heavy) 220 model because of the supposed limitation of 1/8” of the 120 model, and with welds of thin materials, weld time is very short.

Great work, my own sense would be that polyethylene would be a superior material for such a holster.

Another great video. Keep it up. Just wondering why the loop can not be one piece only eliminating the connecting plate, 6 spot welds and labor. For 18 gauge ( 1.2mm ) mild steel or stainless sheet metal the recommended electrode tip diameter is 0.216in ( 5.5mm ) and has to be perfect flat, not rounded with smooth surface and clean. The electrode tips must be aligned until they are coaxial to each other when the welding materials are between the electrodes & the proper clamping force is applied. Sparking is not normal and could be dangerous ( proper protective gear is a must ). During welding it is not allowed angling of the clamped materials, The welded materials must have smooth surfaces in the welded areas, to be clean, free of paint , rust, grease, etc.....I recommend to make sample welds first , twist and peel test them using a wise and pliers and check if the proper welding nugget is formed between the electrodes. Using a timer can further improve the quality of the spot welds

muito bom o vídeo

Tks

9:10 i build my spotwelder my self from a microwave transformer(=MOT) and i can also found the limit at around 1/8 (to be esactly a bit more= 3,5mm). Since the build was so easy and cheap i will double the power by adding a second MOT(700W) in parallel so i can weld double the thickness, the upgrade costs only ~15$. later when i found another MOT i will add a third and fouth so i can weld 1/2inch (with 4mots) Funfact; i could weld thin coppersheet onto stainless steel :D But i had problems connecting different steels types (same type is no problem)

Is there a picture of the finished product. great video and very informative thanks.

Nice Fedora. Looks like a Stetson Gunner.

Wow

Thx for the informative video. Are the arms interchangeable? You mentioned longer and shorter arms.

Are these spot welds very strong ? Iv'e never seen one like that uses and wondered what type of projects it would be used for.

Hi Jeffrey. I liked this video and I'm totally new to welding apart from a couple of things I did at college many years ago. My question comes from an idea I'm being drawn to. I would like to build a dish draining rack from small diameter steel bar (2 - 3mm diameter). So aside from the bending and shaping of the pieces, would I need specially shaped tips on the spot welding points? I ask because I would imagine it would be difficult to hold the pieces together accurately.

Super 🙂🙂🙂

I have loved it! where can I get it jeff?

i get use spotwelding to welding 2 plates de aluminum ?

Hi Jeff, nice video. I like projects with stainless 3mm diameter rods. I currently use TIG welding to join them but sometimes it's too much power and it can easily deforms or blow them because I don't have very low amp features on the machine. I know you said here that your spot welder doesn't handle more than 1/8" combined metals, but is there any chance that it will work joining 2 rods of 3mm each (one on top of other) maybe because rods don't have much metal near the current area and can not dissipate heat therefore forcing heat to concentrate in just one spot and ultimately making it weld? Or can you simply just make a video about it? English is not my main language, I hope you have understood me. Thanks.

would spraying argon during the spot weld keep the brown stuff from forming? How could one keep the brown stuff from forming on the metal?

Defferent types of welding

Nice work! is that a 240V welder? 20 gauge sheet metal? I just picked up a Stark 240V spot welder to do a series of welds in 18 gauge sheet metal. My instructions also state "up to 1/8". I haven't set my welder up yet. I'm looking to get as much info as possible before I start burning. Thanks for posting!

Thanks for the great demo, and God Bless you, and your business endeavors! I too, am nearing "retirement" from my traditional employment/job, and I'm eagerly seeking to jump into doing a variety of metalworking, (hopefully being able to make a good income once I get organized, and produce something marketable (perhaps jewelry, etc., furniture, etc.?!....)! => Best of Luck to you!!! [...."The life so short, the craft so long to learn!"....Hippocrates]

Have you ever spot welded a PEM fastener to sheet metal using the machine you show?

Thanks Jeffrey, why do you let it cool between welds?

Can we use that spot welder to wire mesh

Great video. Out of curiosity, whats the reason for closing the belt loop and not leaving an open clip that could slide over the belt with out needing to undo the belt to slip it on?, similar to a gun holster belt clip?

Dark: I have hte same setup I have welded up stainless steel exhaust tubes. What is the trick to keep the stainless from sticking to the copper contact points?

any thing straight out the box you had to do to get it working? cause I'm having problems

How thick plates can you spot with your spot welder

When you’re doing more than one spot right after the next do you keep the spark on less time time than you would your first one because the metal is already heated? Thanks

Is there any problems with localised oxidisation at the site of the actual spot weld of the stainless? Other methods of welding stainless require a gas shield to prevent oxidisation during the weld process.

Would this weld stainless wire mesh like 10 gauge or 8 you think?

Your HF spot welder doesn't have a weld timer on it I see. Try holding the clamping force for a few seconds after you release the trigger switch. This gives time for the weld nugget to cool while clamped( forge time) for a better weld.

Hi Jeffrey, please tell me how you made this wonderful spot welding machine. I want to make this for my workshop, Please help me. Thank You

Jeff, great and informative video. I never owned a welder of any sort. I am wanting to weld two coat hanger thick wires together for a project I am doing. (One wire crossing over the other with a weld to hold them.) Would you recommend spot welding for welding two wires like this together? Your advice would be greatly appreciated.

Could you recommend a welder for a newbe? I just need it to connect cj7 tub side channel supports in my jeep 1976.. (That way I can install a cj8 half hard top and bulkhead) Congratulations on living your dream job! :)

Have that same welder - didn't get a lot of life out of it - the tong tips go bad at the threads ruining the tong. Harbor Freight

I would have not welded the belt loop closed...allow natural spring tension to slide over the belt.

What type of metal are you using ¿and where to purchase can you be purchased¿ by the yard 'foot?

Sir, I would like to make a large size spot welding machine that will make 5mm GI wire within 1/2 milliseconds. But I do not understand that I am How many volts and how many amperes will make the transformer.plz help me

Hi Jeff, I’m from Indonesia. Can you tell me where did you buy the spot welding machine? Because I’m currently looking for one. And also, can it be used to spot weld 0.8mm aluminum to aluminum with wire mesh in between? Thank you

how strong is spot welding is it possible to weld a bandsaw with a welder like your

Why weld the belt loop? If it is not welded it can function as a clip-on. No need to unbuckle your belt to loop through the belt loop at the beginning and end of the work day.

Can you which is the best electrode is used to welding of ss..

How do you get the edges looking so smooth?

Nicely taught, never done it b4, but would try now. Would spot welding work with aluminum? Thanks, very informative, am encouraged. Good teacher.

The fedora xD

朋友你很棒

What gauge stainless steel is it?

Could you achieve the same thing with a TIG welder?

Hi Jeffrey, I want to weld some pieces of sheet metal 18Ga. For how long should I press the button so I can get a strong weld? For how long should I let the machine rest before the next weld? My project needs 12 spots of weld. And I need to build at least 100 units. Hope you can guide me through. Thank you!

So its kinda like riveting, but with a weld.

How thick is that? Less than 1mm?

So is sheet the only use for this type of welder . I just got a low amp stick arc welder clarke 95 model . I am going to start practicing . But I just seen one like this on craigslist for 30 dollars and I know I will have some use for it . I am doing the finishing touches on a tubing roof rack . A fabricator did the bulk . I have to put some crossmembers for the floor and add expanded metal sheet on the floor and paint yet .

Could a spot welder such as this be used for welding two rebar rods together?

is the currant alternative or Directed ?

Great Demo on Spot Welding. Does work with Aluminum?

Hi Jeffrey, great informative video. How do you think spot welding would work for 10ga galvanized sheet metal? Would that harbor freight weldor be up to the task? Thanks!

Make the Hoops from one bent Piece and save yourself a lot of Time ;)

GREAT Video! Thanks man New subscriber here! do you ever have to replace the tips of the spot welder?

ohhh see ya my friend had those terms reversed. And I thought he was right haha. I had to look it up and now I know that I was correct in my terms.

Great work from your side, i dont know about your mate if he has a car wash or e scratchwash, going in n out of car all day

Satın almak istiyorum nerede bulabilirim

Hi do the arms of the welder get hot?
