If you are tig welding steel with anything other than argon you are going to have problems, CO2 is not an inert gas and that will be part of your problem. From experience tig ceramics will absorb moisture and other chemicals even when they appear dry they can outgas whatever it is they absorbed. Poor storage of you torch may have caused the gas pipe to collapse / get pin holes either restricting gas flow or allowing air in. The other very common problem is bad earth due to cable breakage or clamp making poor contact (arced surfaces)
