You can use anything from 0.25 w above.
Can i use some other similar mosfets? Cant find 1324 at my local stores.

EDIT: never mind i managed to find it.
You can use those or better (watch for max voltage, IR, and gate charge).

Re: JP spot welder

Thank you for kind words guys, the whole idea behind the welder was that is simple, robust and reliable. Enjoyed reading this form. You all saved me from taking my chances on a used Sunkko 788+ welder. I'm interested in buying one. Looks like the JP KIT versions may be all gone now. If so I will go ...

Re: DIY spot-welder, FET-switched, processor-timed adj. pulse

Both options should work fine, but bolting fets down is much more convenient, for installation and also for potential repairs. Also it's a lot less messy, and you're not stressing the fets with soldering.

Yes, they should be slightly better, but are more costly.

Re: JP spot welder

hello riba. is it possible to modify the welder to handle around 2 times the current for welding copper? perhaps using larger or more fets? Hi, I have never tried myself, but I guess it could be possible. Maybe stack two welders, and use one as a master providing the gate signal for slave FETs? BTW...
