Lucky for him, he wasn't shocked, but it made a HUGE spark!
Another time we were machineing on the mill when the bit came loose and flew out. No one was hurt though.

electrical Shock is not the BIG danger:
Spewing melted metal onto skin or worse the eyes is the primary danger!
18AH batteries with internal resistance of .01 ohm are potentially capable of
Ipk= 12v/.01ohm = 1200 Apk
figure in .005ohm AL short then I=12v/.015 = 800A
more than capable of instantly melting and forcefully ejecting molten metal beads 6061 AL melts at ~580-660°C
It sticks to skin.. won't shake off..
BE SAFE! Sane & available to compete with both eyes and no hurtful scarred skin from a bad burn
Safety First..
Never use battery outside of your robot without a series circuit breaker! Never!
start at lowest needed Ampere rating, for testing the lever type is most useful
