| | Has anyone had problems with the Weller MT 1500 IRON/TIP solder station? | | Please advise your problem and resolution. | | | | ddj | | 6/16/99 | | | I don't like to use the needle tips (MT2 series), but the rest of the tips work fine. The MT2s didn't last very long. | Most, if not all, soldering tips are made of copper rods/wire of a specified diameter. They are shaped then tin/lead plated to a minimum thickness of 3 mils. 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.
