Hello,
First of all sorry for my bad english as it is not my native language,
I am newbie in the world of advance soldering and never had training of any soldering station/rework station. A basic training of ERSA PL550A was given. I am having some trouble in profiling of the same machine, as the output soldering profile of the machine is not same as the targeted profile. Infact, output profile takes much time to reach the targeted peak temperature. And if you are a professional in soldering so you must know that a thermal profile must very good to achieve a good soldering.
