Check the gas flow, set around 15-20lts/min, check that gas is coming out of the nozzle by using an add on flow meter to the nozzle if there is a difference then you have a leak in the line and will be drawing air into the gas stream which will cause the holes,
using a gas flow that high will also cause porosity. gas should be
argon/oxy or argonC02 mix 2% or 20%
Make sure you have the torch at the correct angle to give good gas coverage
Hi, This problem has happen to me, My solution was a grounding problem. Take your ground cable, and put it on the table leg.
If this doesn’t work for you, please write back. Thanks,
