Did you have any problems with warpage or distortion & how long did you wait "cool down" between weld runs? THANX!!!You can make your own copper backing tool. Get a piece of copper pipe from a hardware store and hammer it into the shape of your choice. Put a wooden handle on it, heat travels fast in copper.
You can quench it in a bucket of water between each weld.

very clean!!wire feed is very forgiving, but you do want to skip around with any welding and limit the length from a spot to 1/2" long at a time. Walk away and let things cool after a few welds.
Here's the bear claws kit i just installed with that method - using a cheap eastwood mig welder - no warpage and very little spot repair needed afterwards.

It's a little 110 Eastwood China special, bought it 2 years ago because I did have huge holes to fill in the side of a '57 Chevy truck bed. Sheet metal seems to weld best on it at "F" and 6 to 7 on the wire speed depending on how much fill is needed.

Next I want try welding cast iron with it, using Crown 44-30 wire is the ticket I hear.
