Flux core ?
by Tom M
I have a small firepower mig welder. I normally use gas. I had to do some overhead welding which was ok, but probably not very strong. I thought flux core could give me some better penetration so I bought some fabshield 23. I can't weld this wire even flat! So I tried a lincoln wire from home depot. A little better, but still sucks. I have played around with wire voltages, speed, and stick out. I have the polarity correct. Help.
