Features Made of high quality oxygen- copper which is of fast conductance and heat resistance up to 480℃ for use Applicable to 936, 937 soldering station and so on with its pointed end shaped like a needle that is suitable for crafted workmanship, for example, fit the alarm fob of a car, like micro switch had popped off the small circuit board and the contacts for If with appropriate use of iron tip, its lifetime can reach over 20000 welding joints It has advantage of long life lasting and not easily oxidize, easy to install and use It has high safety and stable performance. Quite easy to take and clean. Use the sponge to polish the surface. Please do not leave them exposed to the air, better wrap them with tin Specification: Description: These iron tips are electroplated Iron and which protect them from oxidation, characterized by heat-resistant up to 480 ℃ and lifetime over 20000 welding joints with appropriate use. As the point is very sharp, it fits for crafted workmanship, for example, about car problem, once micro switch had popped off the small circuit board, you found that the contacts for the micro switch is smaller than micro (smaller than a pin head), or soldering in a narrow space also for revising the tin bridge emerging from chip soldering. How about getting this set and making your soldering work easier?
