Demagnetizers

[olderdan]

Thanks Marv. How would an ac spot welder or an older type transformer stick welder do as a demagnetizer for lerger items, like spanners? I appreciate it's not wise to let either or any welder effectively short circuit for more than a few seconds. I presume the effect would be the same?

This will easily demag spanners and larger items.
