I thought that it was very good because it can be used as it is with the 300w product I have used until now. Although the direction of the damage of the sword tip was intense although the trowel which I used until now, how much this time is still unavailable because the usage period is still shallow
The upper part of the hand gets quite hot. I was worried because I am working style that does not use gloves as much as possible. Then, although the attached tip shape is a tip shape, it is better not to use a square pyramid but a triangle. If it is a square, the contact area is too large when soldering the inside of the corner, and solder will stick to unnecessary places. For others, it is easy to use and has a sufficient calorific value.
