Four helicopter tail motor broken, and want to buy an electric iron to weld, please buy electric iron is inside or outside the hot good?Still want to ask, "Fauji West (Forgestar) of 7 portable Z017N-7 set" and "Ai Wei bor (Everpower) 959001 zipper cloth 7 piece electric iron suit" the two suit which is better?
First, you can not say absolutely that kind of good, depends on what you use: welding small pieces, such as electronic components, the internal heat of the good; welding large pieces, the use of hot outside.Second, the structure is different: the internal heating element in the copper head, its thermal efficiency is relatively high; the outer heat of the electric wire in the copper head outside, the power of the iron and the metal area welded.Third, power: small power electric irons are generally internal heat, suitable for welding small pieces. Such as welding semiconductor device and integrated circuit power is not greater than 30W. High power iron is generally outside hot, welding larger. The greater the metal area, the greater the power of the iron used.Fourth, the heating speed is not the same: internal heating type heater, a large head, short service life, are usually small capacity; external heat slowly, small head, long service life, can be used for large capacity.
Personally think that the internal heating type electric iron is relatively easy to use, because the iron head of external heating type electric iron on the market is not easy soldering, inconvenient welding, welding and if things need to place the leakage and temperature is not too high, then the thermostat electric iron with leakage protectionIf welding requirements in general, on the market right to buy an ordinary electric iron can be, a few to more than a dozen
The electric iron is hot. I suggest you buy a constant temperature electric iron.
