I was told years ago by an old man you can "Effectively" weld aluminum with a DC arc welder. Never seen him do it.
Since then I have been told by several folks including all the welding supply houses, that it can not "Effectively"
be done. That say "it just don't work very well."

I have been swapping these trolling motors around the last week or so, having to build brackets and what not...
So I go buy some of these aluminum rods.
All I can say is I am VERY impressed with the rods. It took a little time getting it to look good but listen here folks,
I was in my driveway, in the wind and the rain, welding my aluminum boat.
If someone tells you that it dose not work very good... Let me have a chat with them!
