these welds were done with a 110 volt MIG on thin sheet aluminum, mostly just to see if you can effectively mig weld thin aluminum with a 110 volt mig!, having these pictures is great because its an excellent teaching aid!
cold mig weld on aluminum, certainly not structualy strong
still cold, and not penetrating well but better
the center weld above is obviously hot,enought to get good penetration, not cosmetically pleasing perhaps, but ID sure bet its fine strength wise
