I’m also seriously considering donating other good tools including a 3d scanner (needs Windows 8/10 PC to run), battery spot welder, 18v and 36v li-ion cordless power tools.
I’d need to know they’d be well looked after and be able to use some of them quite regularly.
Some require 3d printed and/or laser cut and/or soldered parts to be used to their full potential.
I’ve also got loads of electronic and computer parts and components, adapters and tools.
Grab one of the directors next time you see us to have a chat about this, and also see the donations policy 
Donating or Lending Items
It’s always appreciated when tools are donated, and if they are of good quality we will do our best to look after them , diy grade tools are just not up to the task .
A spot welder would be ace (assuming you mean the one that is for battery tabs)?
Yes battery tab welder with weld leads for easily making large battery packs
