Re: [MW:15971] Defects due to porosity

Rahul
How often is the porosity occured. If its repeated in an uniform periode, I suggest you to check the condition of the tungsten electrode. Sometimes dirty and dull electrode may cause porosity. Just regrind and clean the tip might give a solution

Just from my humble experience
