Ideas needed!
« on: February 25, 2018, 07:31:40 AM »
hi,

i recently picked up a decommissioned mig welder from a mate. he said for some reason the case and handle was missing but the internals are all still good. so it got me thinking.... what could i use these cores for? i'm thinking as an inductor for a boost converter?  being a mig welder it would just be a big step down transformer with most likely a 12-40v output at 80 amps.

From the picture those cores look like laminated steel. If they are designed for 50/60Hz then you won't be able to run them at the higher frequencies used in a switchmode (e.g. buck or boost) converter without huge losses in the cores.
Someone might have other suggestions for use though.

Well that's what he said. Works ok till only 400hz if I remember. Why not use it as a mig welder? ::)

@Hydron
I didn't even think about that. I just saw a big core and got excited!

@AndreiRS
I don't think I could justify the parts cost to get it running again, as well as I have a few other welders.

As you sit with 50 Hz parts it is hard to really reinvent it outside its original purpose.

One useful purpose, if you do not want a old welder, could be a spot welder for building prototype enclosure.

I actually also googled and found this from a welder manufacturer: https://www.everlastgenerators.com/blog/top-10-things-do-old-welder

Haha mads... I think I could use number 5 as an option! I think I'll see how much current the transformation draws when connected to mains, if it's not a lot I might just use it as a power supply if I get into high power zvs drivers

Why not just convert it to a high current PSU? They can be very useful for driving induction circuits among other things. If it's a three phase transformer you would get a pretty low ripple voltage.

You might be able to use it as a ballast for a SGTC HV transformer.
