Weller Soldering station temperature increase

Weller Soldering station temperature increase

I have an old (30 years) temperature controlled soldering station very much as pictured on your Web Site. It still works great with old (30 years) solder. Is there a way I could increase the temperature of the tip to handle new solder. Otherwise I will have to throw a perfectly good soldering station in the trash, eat 1 pound of 30 year old solder and suffer dementia.
