Some lead free solders will strip the plating off of some non-pb-free-compat=
ible irons and tips.
Also, even if the plating is not stripped there can be problems as the lead f=
ree solder dissolves all the lead tinning from an iron meant for lead/tin. O=
xidation, or what looks like it results.
Jjust one set of possibilities.
