Description: These iron tips are electroplated Iron and Nickel which protect them from oxidation, characterized byheat-resistant up to 480 and lifetimeover 20000 welding joints with appropriate use.As the pointis very sharp, it fitsforcrafted workmanship, for example, about car problem,once micro switchhad popped off the small circuit board, you found that the contacts for the micro switch is smallerthan micro (smaller than a pin head), or solderingin anarrow spacealsoforrevising the tinbridgeemerging from chip soldering. How about getting this set and making your soldering work easier? Feature: Made of high quality oxygen-free copper which is offast conductance and heat resistance up to 480for durable use. Applicable to 936, 937soldering station and soonwith its pointed endshapedlike 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 andthe contacts for the micro switch are smaller than micro (smaller than a pin head), or soldering in a narrow space, revising the tin bridge emergingfrom chip soldering. It makes soldering those delicate, tighter connections much, much easier. 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 oxidized, 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.
