A "tip" for Weller soldering gun users....I've noticed that sometimes the tip doesn't heat up as hot as it should....A good re-tightening of the nuts that hold the tip in place takes care of that. Also...if you use acid core solder, the acid will eat through the copper tip to the point where it breaks....Need a new tip then...

One should never use acid core solder to solder anything but plumbing anyway, and in that case, a blowtorch is the best way to get it to melt properly anyway. Soldering irons are for rosin core solder or for use with other non-corrosive flux solder. We sued solder with a water soluble flux in order to make it easy to clean up afterwards. Rosin flux requires the use of a solvent based cleaner to do a proper job.
