[Elecraft] Solder and flux

[d.cutter at ntlworld.com]

I find solder wick works much better if you wet it first with flux: I use a flux pen from Chemtronics #CW8100

> An excellent method...In the absence of rosin flux, remember that fresh solder contains flux...Reheat the reluctant joint with a clean, hot iron then just TOUCH the tip-joint juncture with fresh solder and the joint will quickly liquify, allowing whatever rework is necessary, be it the removal of excess solder or eliminating a cold joint...
