Roger, it's a continual learning curve for all of us.. Believe me! On the welder setup, I normally have it pretty well dialed in from using the same stuff all the time, but I wanted to try the -7 again on a higher heat setting to try the difference. Never hurts to practice on some scraps to save any "aw fudges" on the good stuff..

As always the pictures make the repair look great. And thanks for sharing the info as always!

It's hard to place all the blame on the wire alone, as my welder has too large a liner for the .023 wire, where it tends to accordion, if you will. If you were to pull the wire at the end and trim it, then the machine has to fill the voids side to side before effectively pushing the wire out the end again. This is something I've known with my welder but was trying to minimize any heat on the roof panel. Comparatively, I'd say they are similar in flatness of weld, softness of weld, and the only difference being the slight extra splatter with the EZ. If someone has a smaller welder with the smaller liner, they would likely have better results than with the 25+ year old beast that I'm using. With either, I'd say you'll have better results than with the harder welds of the -6 wire. I never gave it much thought until someone asked the question of shrinking effects on the allmetalshaping site, but comparing both of the -7 and EZ to the -6 wire, I think the -7 and EZ may have slightly less shrinking effects as well. This may attribute to the harder weld of the -6 is "compressing" more than the other two.. Just a guess, I'm certainly no metallurgist to speak fluently on the matter...
