HA! true. I tend to treat high amp and high voltage systems with some caution.
When you weld together a pack of 12s in 3/4p and have 60-100Amps current - i’ll stick with the arduino spot welder i built from pcb and BOM. It was a fun project and i can control the timing in milliseconds. Not prius/tesla car volts/amps - but more than i want to lick my fingers and touch contacts!
