Reply:Looks like a size 6 or 7 cup to me Zap.Ya, i'd use either 6 or 7.  Although a 5 may work too, I think it may be too small for the big puddle you get on aluminum.
Reply:Originally Posted by SupeI use it for almost every open root bevel and pipe I do with a heavier wall thickness, as it makes for a VERY consistant weld.
Reply:You will rest the cup on the material itself and rock it side to side as you travel up the piece.
