macfjej, I have that exact same iron too. I just recently got a chisel tip at Radio Shack and it seemed to be a night and day difference.
This is what I got for mine, only it came with 2 of the smaller chisel tips. There are light duty tips, but I'm not real sure about them because they are "iron clad". Just like Brian G said, don't drip the solder on the joint. I simply tin both surfaces, put the wire on top of the connector/other wire and push down on them with my soldering iron, melting the solder around the joint. Only one of my joints has failed so far and it was due to incorrect plugging. Be careful not to melt the connector. Just make sure you use good solder, good 12awg wire, good quality connectors, and/or battery bars and you should have no problem with that iron. Don't forget to be patient too:025:.
Damon and Johnny, thank you, I'm glad y'all like it:027:.
