When welding, maintain the temperature stability is very important. Temperature is too high, electric iron head overheating, not only will damage components, and electric iron head oxidation speed will accelerate, shorten service life. So how should the electric iron head overheat? Following by the hot air gun tool manufacturers for all worries:

1, cut off the power supply for cooling.

2, the heat and the unused iron into the metal iron frame, using heat transfer and heat a large area of effect to the electric iron head cooling. When using the iron is removed from the iron cage, then the iron iron frame without heat, will soon rise to the welding temperature.

3. A series of parallel circuits made up of a diode 1N4007 and a switch on the power line of the iron. The iron is not used for a long time, it will switch off, so that iron can only get half period of the power supply, the temperature will not overheat in the iron, when in use, the switch is closed, so that the iron has normal power supply, the temperature will rise.

4, ordinary electric iron can be a simple electric iron rack, iron frame installed under a microswitch, put on the iron after power string into a rectifying diode to reduce temperature, picked up after the full voltage heating, can also prevent the electric iron burned.

5, tip with natural cooling as well, forcing cool water, will shorten the service life.

6, electric iron long time electrify, will appear the phenomenon of high temperature and shorten the service life, and the iron Tsui is easy to "burn", causing "tin" difficult. Constant temperature welding table energy consumption is relatively low, adjust the temperature, it will not be heated, that is, the same welding effect, welding platform less electricity. You can choose the constant temperature welding machine, electric iron head overheating problems to solve.
