all the setting are the same as before it left. i have made a few changes to the cut but cant seem to get it to smarten up.
on 1/4 plate, 60amp tip, air pressure 75psi ( attempeted from 65 - 85 ) and cut speed from the suggested 86, down to 50.
the cut is very jagged, and has a huge concave to it.
i have used cut heights 0.06 ( from the pre loaded tool set ) and 0.09.
any help or suggestions?
it has never cut perfect but fairly decent. horrible now....
also has seem to always have an issue with dross, especially on thinner material like 10gauge
