Features Made of oxygen-free copper which has fast conductance and heat resistance up to 480℃ for long lasting use. Applicable to soldering stations 936, 937, etc., with its pointed needle-shaped end which is suitable for handicraft workmanship, for example, it fits a car alarm remote control, as if the micro switch has come off the small circuit board and contacts for If the iron tip is properly used, its service life can reach more than 20,000 welded joints. It has the advantage of long service life and is not easy to rust, easy to install and use. It has high safety and stable performance. Pretty easy to carry and clean. Use the sponge to polish the surface. Please do not leave them exposed to air, better wrap them with tinplate. Feature: 1.

Specification: Description: These iron tips are electroplated with iron and nickel which protect them from rusting. characterized Heat resistance up to 480°C and a service life of over 20,000 welded joints with proper use. As the tip is very sharp, it adapts to craft work, for example, about a problem in the car, once the micro switch came out of the small circuit board, found that the contacts of the microswitch are br/>smaller than a micro (smaller than a pin head), or weld in a narrow space also to check the Tin bridge arising from the soldering of the chip. Specification: Material: Copper Colour: silver. Plating: Iron & Nickel (Finish) Outer diameter: approx. 6.7mm/0.26 Inner diameter: approx. 4mm/0.16 Length: approx. 17"/16.93" Package weight: approx. 47g Model No.: 900M-T-I Applicable to: 936, 937, etc. Range of Package List
