I ran out of gas for my mig so I thought it would be a good time to learn some on tig. The photo shows my problem, porosity. The metal was clean of all mill scale, the cuts were with a band saw and there was no oil on it. I thought maybe I had the flow rate to low on the argon, it was at 20 cfm so I upped it to 30 cfm, no help. The tungeston was 2% thoriated, i made sure not to dip it. I did notice that the tip was yellow after I would weld.
Any ideas? Thanks, Justin
