Four Types Of Heat Guns
Jul 24, 2018

There are many types of heat guns, such as high temperature heat guns, digital temperature display type heat guns and standard type and ordinary type heat guns. What are the characteristics of these four types of heat guns? Let's take a look.

1, high temperature heat gun

High-temperature heat guns usually have one or two temperature sensors for temperature control, and an anti-drying device is built in to prevent the heating wire from being overheated due to lack of wind. In addition, the temperature can reach 800 ° C or even 900 ° C, but in order to achieve such a high temperature, it must be fixed on the equipment connected to compressed air or high pressure air source.

2, digital temperature display type heat gun

Digital temperature display type heat gun digital temperature display type This is basically the same as the standard type performance, which is an additional digital temperature display, and some are very accurate. However, some display temperature is not accurate, it is easy to produce false feelings. In addition, the digital thermometer has been measured. The actual operating temperature is: (small head tuyere) is 350-400 degrees at the tuyere, about 300-350 degrees at one centimeter, and 260-300 degrees at 2 centimeters. It can be tested with a digital multimeter with a thermometer. At the same time, some machines have power or other voltage and current indicating dials. Some parts are replaceable. If you are using a heat gun without a digital temperature, you can use a wind gun to blow a piece of paper at 3 cm to estimate if the paper does not turn black quickly, it is appropriate to slowly yellow.

3, standard type

The standard type of heat gun is about five or six hundred. The scale of this type of heat gun is really used to adjust the temperature. It can be heated up quickly when it is turned on, and can be reached in tens of seconds, and the temperature does not rise straight, and the range is adjusted in a small range. The air volume is also relatively stable, suitable for repairing mobile phones. I use this kind of air gun very well. For example, the CPU of 3508 will not burn out more than 90%.

4, ordinary type

Ordinary type temperature is unstable, high and low, and the air volume is not stable. The market price is about 300, but according to the experience, the heat gun of this model has a short service life and it is easy to lose money. The scale of this kind of air gun is only to adjust its power. It takes a few minutes to warm up when it is turned on, and it rises in a straight line. It is easy to burn out the circuit board and other electronic components, such as power amplifier, CPU, circuit board and so on.
