Wink MOSFET vs IGBT welders

This article explains the differences and major advantages of IGBT welders as opposed to the MOSFET transistor models.

You could not give me a MOSFET welder or plasma cutter.

No BS just the facts.

Cheap Eastwood welder still uses MOSFET and not Igbt.

Yes. I work in an air force electronics lab and have over 40 years electronics experience and have a some engineering stink on me.

Don't trust mosfet at all, ever.
