This is really helpful. I wondered about the power setting, but since I am having trouble burning through, more heat seemed to be going in the wrong direction. I definately will try the copper heat sink, and I have been clipping the ends. It sounds like I am on the right track and just need more time welding to improve. I will send better pictures this weekend as I am out of town this week.
Thanks for all the help.
