* Avoiding wet areas (but mention industrial water-damped cutting)
* The plasma cutter plugs into one of the 16A sockets on the pillars. If you need an extension lead use only the high-current industrial ones from drawer B1B of the metal table
* Main terminal on power supply is live all the time at 100V, ensure the guard is in place at all times
* NO RINGS, NO WATCHES!!
* If something does go wrong, shut off power before anything else

| Proper settings for the job ||
* Selecting proper pressure and how to cascade the regulators to give smooth regulation.
** Pressures range from around 3 bar for thinner material up to around
* How to choose a suitable current for your job
** Theoretically you should use 10A + 5A per mm of material thickness for steels, more for aluminium or copper
** But this cutter's gauge reads "Chinese amps" so use about double that
** But the breaker will trip if you select over about 42A so that's your upper limit

|How to
* Demo on thin sheet
** Show a good cut, too much current, too little current, too little air
** Practice on thin sheet till it's working well
** Piercing through
