My plasma cutter stopped cutting. The loose-nozzle indicator light

it started cutting again. Then stopped again "loose nozzle" again.

So I opened the torch & checked the nozzle switch - it was OK. Crap!
Now it was something in the hose, or worse - in the electronics. So
I got out the manual to look for a schematic. And stumbled across
the page with the indicators explained. 'Turns out that "loose
nozzle" means a loose nozzle only when steady. When it's flashing,
as mine was, it means worn electrode!

"One if by Nozzle, Two if by electrode"?

So I put in a new electrode & nozzle and I'm all set. 'Least I
didn't start taking more stuff apart.

Kick me,

Naaah.

I learnt that half the time, error indicators are devices used
to steer the user *away* from the issue at hand.

My waffle iron *turns on* a light labeled "Preheat" to indicate
that the waffle has finished cooking.

Rumor has it, there are computers and cars which you *turn off*
by first pressing a "Start" button. (I am not making this up.)

Many HP calculators also only have an ON button which is also used to
turn it OFF. Still haven't found an "=" key.
