I have the 62i along with the Pro table…it has never given me problems …except for user error…
if you are looking at cutting thicker metals it is a power horse…
I ran a continuous 20 minute cut on 11ga making a firepit…no problems…
but you need to ensure you have clean dry air…and buy the proper tips…do not buy knock off…
if you are cutting thinner you might want to step down to the 52i
