Hey guys can anyone help? I'm gonna be soldering some 1/0 gauge reducers. I'm gonna be using 60/40 rosin core solder with a torch. Is there any specific brands of solder that I should be using and if I'm using 60/40 rosin core do I still need to use flux paste? If so, what kind? Preferably something I can find locally at a store thanks!

Would definitely do business with Ken again, had my items shipped super fast just in time for me to install them. Thanks!
