Strength of a flux core weld?
My budget lead me to purchase a flux core welder, and it has worked for the patching and light fab work I have done so far. My boys want to build a mini chopper and I need some feedback on the strength of the welds using flux core. The welds appear dirty; does the flux create inclusions that would weaken the weld? Or is this just an appearance thing? I can live with a patch falling out, but not a fall from a broken weld.
