Hawk,
Thanks for the tips . I will try that tomorrow and let you know.

I have been practicing with the Dyn.200 I seem to get the "grey" film without grinding it off. I know some of the marine tower builders don't like to grind thier tubing or so I have been told.

I am practicing on some Anodized tubing and I am having trouble with the anodizing floating up in the weld puddle making it look like porosity....I was told to grind it off before I weld, is this correct or required?

The machine you need is made by "Dynaflux" or "Walter" any welding supply should have info on it.
