Plasma cutting
Plasma cuttingis a pro"ess that is use! to"ut steel an! other metals o !i'erent thi"knesses orsometimes other materials like ro"ks using a plasmator"h,
In this pro"ess# a gas 4o)(gen# air# inert an! others!epen!ant on material5 is $lo*n at high spee! out oa no22le6 at the same time an ele"tri"al ar" is orme!through that gas rom the no22le to the sura"e$eing "ut# turning some o that gas to plasma,
.he plasma is hot enough to melt the metal or ro"k$eing "ut an! mo&es ast enough to $lo* moltenmetal a*a( rom the "ut,
