Are you welding hot rolled, cold rolled, how are you prepping (cleaning) the material?

This might be a good time to post a picture. There are many things that could be described as holes, but each may be caused by a different problem. Then we can narrow down the things you may want to check. A picture of an uncleaned weld and the tungsten will be the most helpful.
