[grandads_shed]

hi i got my plasma cutter delivered today ,, and looking in the book it says that the air pressure needed is 4kg .. any one know what this is in bar ?? or ibs inch ??
as for the compressor that came with it ,, well there is nothing about its air flow rate that it can do ...

I've had a Cut50 for 4 years now and it says 40psi but i find 55-60psi is way better

My Oerlikon demands 4Bar (about 58psi), it'll work with less but eventually the under-pressure cut-off kicks in.
