Jman, Saw your post on welding anodized Al. pipe. Have not used your technique, but am going to try it. Do you use foot control or remote switch? When your "bump out" the weld will the contaminated anodizing flow to the edge of the welds? Also by pulsing with out rod, I guess you are make a pretty cover pass? Thanks for any help you can give me, I am a aircraft mechanic, and do mostly stainless and Al. aircraft parts. I live on the Gulf Coast of Florida and have built a couple Tee tops for my own boats. With out any knowledge of anodized Al. pipe welding or advice, the start of the process was very frustrating. I saw great welds on other boats, but had a hard time duplicating them. Presently run around area to be welded with the High freq. to clear out the anodizing, then come back and weld. Have make a lot of progress, but still not satisfied with appearance. One top has been in use 3 years with no cracks, so I must be getting good penetration. Thanks for any help or advice you can give.
