List, I need to do some weld repair on the flanges of the front and rear shroud. The shroud material is 0.063" BS 1470NS3 which is similar to a current day material EN AW-3003 Aluminum Manganese. I was going to Mig with Argon using a 4043 wire. Does the list have any thoughts or recommendations for this work. Richard Cincinnati 65 BJ8
