Solder Iron/Tip Problem! | 16 June, 1999

Has anyone had problems with the Weller MT 1500 IRON/TIP solder station? Please advise your problem and resolution.

Very sharp tips are difficult to plate effectivly as thickness drops of in sharply defined areas. This explains many premature tip failures as needle types, etc.

If your tips do not meet specified requirements, they need replacing with better, more reliable types. Iron is neutral to soldering processes. This is why it is plated as indicated above. If copper becomes part of the equation, solder joint contamination results. Also, tips simply do not "tin" as required because of copper oxidation and aforementioned contamination.
