I have built this inverter with output regulation and they work more efficient.. thanks for inspiring me

[kfoltman]

I think there is absolutely no need to apologize for this "silly" project (other than Youtube is a tough crowd sometimes). It is quite impressive, saves a lot of space (for us folks with a small workspace it's a big plus!), the arc looks as stable as from my big (and not cheap) inverter. It does most or all of the jobs needed in hobby welding context. And in case it breaks, you can repair it easily.

It's a great project.

Hiciste la soldadora inverter más chica del mundo. Tu canal y conocimientos son increíbles, me alegra que youtube tenga creadores de contenido como vos

[sidewinderamm]

I would love to know how you figured all that stuff out about the core, how you did the calculations on output power, air gap, turns, etc. Maybe you could do a video on that?

I Love the Linesman Pliers as a "Stinger"!

Might eventually arc out in the pivot joint, but, Hey!

This concludes a wonderful DIY adventure. Thanks so much for sharing your knowledge and passion! SMD components should improve cooling without sacrificing the size. Why not adding your 555 timing circuit and allow this welder to do spot weld for batteries tabs or thin sheet metal as well? I'm sure a portable all purpose welder would market profitably to DIYers.

WoW!!!! very cool. I like the way you explain it to us all. Keep on creating.

[المخترععودةالكاطع]

you have high level of Electronic knowledge i follow your videos .
thanks

Hi my friends
This files that is uploaded, don't open with sprint layout 6 software.
I think that it is broken.
Please upload them again.
Thank you...

[murraymadness]

can you make it constant voltage so it work for MIG?

[volkerball]

Awesome tutorial. I'd like to see a Mig/Mag or Flux Cored inverter PCB if it's possible.

[ohmedarick]

wow awesome device. How complex would be making a plasma cutter ? Thank you

[Dc_tech]

Can I ask you this question the cord use for main power transformer is it ferrite or powder iron I am making push pull inverter and I need to know which core is better for low heating of the mosfet

[fabriciolima]

Hello good afternoon all right? I liked your project, but describe more about the main transformer of how to wind it up in this configuration that your circuit remained, because I have many doubts. thanks

[paulbehrens]

You briefly got me all excited. JLCPCB prices start at $2 for 5 pieces not 10 (unless I'm missing something).

[hamedsabet]

I like your useful video & i think it will be very fun if build a inverter furnace.

[crusaderanimation]

Well i wonder if making a case with thick aluminium with groves and using this as radiator would improve performance without sacrificing dimensions.
I know that in audio amplifiers this solution is used.

[victoryfirst]

Can you tell me the duty cycle of this welder ??? Thanks. Can you tell me if you could do the same thing in a plasma cutter somehow ??? Thanks again

[michaelhightower]

I have the ZX7-250 220V it came without the electrical plug lol just a blue and brown wires showing!Now my questions to you is #1 What kind of USA plug do I need for this welder to work right with the 220V ?#2 Is how is this welder grounded 🤔 With just these two wires that needs a plug that put on the electrical power cord?

[denskychannel]

Im just asking why the output transformer in some inverter welding machine no electrolytic capacitor? 🤔🤔
