Really want to thank you for the help with this problem. Finally found what the problem was. ME!!! I know you've heard the saying You have to be smarter than the equipment you are operating. Holds true here for sure. Didn't have a wire from the wire feeder to the positive side of the power source. put that wire on now it welds like a champ. Guess that's what happens when you let a carpenter hookup a wire welder. Want to Thank You again for the help and advice have learned alot about this machine while trying to find the problem.
Thank again
Jeff
