Model: 900M-T-I
* Silver Series Lead Nakamura environmentally friendly iron Tsui， high temperature， more suitable for a high melting point lead-free tin solder.
* Ability on the tin， no oxidation， no not on the tin， non-stick tin， tin climbing phenomenon.
* The surface light and delicate， exceptionally strong anti-rust.

Tip Use and Maintenance
Appropriate use of the tip and always pay attention to the tip of cleaning and maintenance， not only greatly increase the life of the tip， but also excellent heat transfer performance can take full advantage of the tip.
Care tip:
1. before welding work
You must first clean wet sponge with water， then squeezed the excess water. Only in this way can make the tip to get the best cleaning results. If a non-wet cleaning sponge， would tip damage on the tin and lead.
2. When welding work
The following sequence of welding tip can get solder protection and reducing the rate of oxidation.
3. After welding work
First temperature to about 250 ° C， then clean the tip， combined with a new layer of tin as protection. (If you use a non-temperature soldering iron， first power cut off， so that the tip temperature slightly lower after the tin.)
4. Caution
a. Try to use soldering
A high temperature will tip accelerate oxidation， reduce tip life. If the tip temperature exceeds 470 ° C， which is twice the rate of oxidation of 380 ° C.
b. Do not put pressure on too large
When welding， do not pressure too much， otherwise it would tip damage deformation. As long as the tip can fully contact pads， the heat can be passed. Also select the appropriate tip can also help heat transfer.
c. keep the iron head tin
This can reduce the chance oxide tip， making more durable tip. After use， the tip temperature should be slightly lower after adding a new solder to make tin layer has a better oxidation effects.
d. Remain tip clean and immediate clean-oxide
If the head of a black iron oxide， the tip may be not on the tin， then it must be cleaned up immediately. When cleanup first tip temperature to about 250 ° C， and then clean the tip cleaning sponge， and then on the tin. Repeated action until the oxide to clean up.
e. selection of low activity flux
Active high or corrosive flux accelerate corrosion when heated tip， it should use low-corrosive flux.
Note: Do not use sand paper or a hard object to clean the tip.
f. The soldering iron on the weld metal frame
When you need to use a soldering iron， you should carefully placed on the soldering iron suitable welding metal framework， so as not to tip from impact damage.
g. Select the right tip
Select the correct tip size and shape are very important to choose the right tip can work more efficiently and increase the durability of the tip of the degree. Choose the wrong soldering iron tip will affect not play the maximum efficiency and welding quality will therefore be reduced.
Tip of the size and heat capacity is directly related to tip the greater， the greater the relative heat capacity， the smaller the tip， the heat capacity is smaller. Continuous welding， the use of bigger tip， the less the temperature drop. In addition， because of the high heat capacity of the tip， can be used when welding relatively low temperature， the tip is not easy to oxidation， increase its life.
Stubby tip heat longer and the young tip faster， and more durable. Flat， blunt tip than the pointed tip can deliver more heat. In general， the tip size without affecting adjacent components as the standard. Choose full contact and solder joint geometry can improve the welding efficiency.
Note:
When you need to replace the tip， select and confirm the original white tip tip models. If a non-original white tip or tip models do not match， it will affect the performance of the original soldering iron and damaged heater and circuit boards and other components.
