Why might a soldering bit fail to tin properly, either from new or in use ?
As a new bit heats up a layer of oxide will form on the surface, this will make tinning very difficult. This can be prevented by tinning as the bit is warming up. The oxide can usually be removed from a COLD bit by GENTLE use of “Scotchbrite”. If the bit will still not tin try using Multicore Tip Tinner & Cleaner. Use only as a last resort at its aggressive nature will shorten bit life.
