Upgrade: More Current Spot Welder

[@sreekumarUSA]

Greetings from California. I am quite impressed on this hack. FYI I ‘had’ the similar unit for some time. Afterwards it died. TRIAC failure. It wasn’t adequately mounted on a heat sink, first of all. Secondly, the board was not designed well. It had it’s own issues and faults. The mains was dangerously close to other areas thus posing the welder; danger to user. There were other issues too. I was not too keen using it and I dumped it, though I saved the transformer. You exhibited a new era to upgrade the transformer. That’s fantastic. Now this job is for the weekend. Thanks buddy. 73s.

[@SteveWillsonKujur]

Thanks for the comment I'll suggest you to get aftermarket controller board

[@sreekumarUSA]

Yes, That’s what I have done. The Logic board was only $12.50 no shipping. Hey, I gotta thank you for the tip. 73s

[@SteveWillsonKujur]

@@sreekumarUSA You are most welcome, my board is also on the way , stay tuned for new Video

[@SonnetGomes]

This is just brilliant. I must try this out. Thank you so much for sharing.

I have just modified my Sunko 737g using this method . Works muc better on half power now. Thanks .

[@TheSupernaturalEyes]

Gained a sub! Sweet shit dude! I was struggling with my spot welder earlier took me 5 hours to spot weld a 16s10p but I only was able to get the parallels welded did this about 2 hours ago had it back together in about 45 min about an hour later I have half my pack in series!! Thanks a million!

[@nexex9053]

Your projects are just ashwome. 👌👌

[@TheCullizko]

Could you help us and share the dimensions of the transformer and the voltage it delivers to the end of the tips. Thank you.

[@ee-sj8qr]

What is that white sleeve that u use to wrap the wires?

[@jamesbrady2156]

Has anyone thought about extending the arms that hold the welding pins? I purchased 1/2" x 1/2" brass square stock and extended the arms 4 inches. That gave me a world of room.

[@ideafromkurdistan5257]

This type of cable available in local market ?

[@malakeasmaa7552]

Please how to make the point welding machine for the 18650 battery

[@calyfornykid]

Steve do you know where to get parts for these welders? My yellow plastic holders that hold the welding pens broke while I was tightening up the Philips screws, or maybe you might have an idea how I can rig one up. Your assistants would be of great help, Thank you.

[@das250250]

Did you keep the winding number the same or did you double the winding number ?

[@tm4853]

i have a 737g spot welder that is not responding the lights are showing its welding but nothing,can you give me any tips on how to make it work again or even upgrade,thanks

[@mrgreenswelding2853]

You Should put more turns on the transformer. That helps way more

[@das250250]

How will that help ? it will increase the voltage and halve the current capacity .

[@mrgreenswelding2853]

@@das250250 no, not if you put thicker wire in. I did mine and is far better now than it was.

[@ajithp2714]

Hi Steve nice upgrade. I have a question, I made a spot welder using transformer and controller board. I felt the secondary transformer voltage / spot welder voltage, i designed is low. Due to this my welds are not good. Can you tell me the welding voltage for the spot welder.

[@ti3apache1]

Genial idea. Muchas gracias. Coloca un resorte, fuerte, bajo el primer tornillo. De esta forma, solo tendras que bajar las agujas con un movimiento y la soldadura quedara impecable.

[@hemantraghuwanshi5306]

Sir in sunkoo spot welding machine what is the transformer core size and primary guage number

[@mdaslamknl]

Excellent Do you recommend this spot welder, planning to buy 1 Thanks

[@cing99]

hi what cable size you add ? 10awg or 12awg

[@RollingThunder85]

Can I convert this thing to power a 12v car amplifier in my house

[@MotoAlias]

Actually yes I was playing around with a transformer today had a bunch of windings and got 30 volts so I unwinds it some and eventually got it to 12volts and I connected it to a 12v dc fan powered it no problemo

[@shivam000]

But there will be programed max limit?

[@TheWasch24]

What gauge wire did you use

[@zjoesmoe2670]

Very cool 😎

[@nadeemuk6194]

Hi brother I am new starts please do you be able to brief me which spot welder is okay mini or same as you?

[@edgarramirez-xo2ep]

Can you make this machine from 220v to 110v

[@excite236]

You will have to change the primary winding on the transformer. It's much more difficult.

[@dwijabarsahoo6204]

When will the next video come

[@Ash-bx6kq]

song?

[@jkaudios612]

Please give me a dc to dc buck converter used in battery pack charger

[@hellen8766]

не делайте так никогда, ужасно соединять высокотоковые провода с помощью свинцового припоя, он обладает сопротивлением еще хуже чем сталь, следственно потеря мощности там где применяется припой, надо было просто рассверлить посадочные места под больший диаметр провода do not do this ever, it is terrible to connect high-current wires using lead solder, it has a resistance even worse than steel, therefore the loss of power where solder is used, you just had to drill the seats for a larger wire diameter

[@mdfahim4684]

Thank you

[@RavindraRaikar]

This is surely going to burn primary winding, that little transformer is not ment for overloading..

[@robertobusek8414]

Waste of time- I tried this thinking it would increase the current. The core limits the amount of power transfer to the secondary. It does nothing to improve the weld or power at the weld points.

[@neiliewheeliebin]

Try more turns on the secondary, the best spot welder i have uses a 12v transformer & welds 0.2 perfectly

[@jkaudios612]

Sir one kind help

[@jkaudios612]

Sir please

[@jkaudios612]

Please sir
