The working principle of gas soldering iron, the use of gas soldering irons
Gas soldering irons (self-heating irons) utilize the heat generated by the combustion of butane gas to heat the tip of the soldering iron to complete the soldering job.
In addition, gas soldering irons can be used to fuse plastics, tighten heat shrink tubing and spitfire heaters with hot air, which can come in handy in many soldering environments.
Butane gas produced by liquefied butane is ejected at high speed from a gas tank and ignited to create a flame for heating.
Note that the soldering iron tip is not heated directly (low thermal efficiency), but rather, the flame heats the porous ceramic matrix catalyst, which radiates a large amount of infrared rays when it heats up to red (patented technology).
The gas soldering iron has a high thermal efficiency and a flame temperature of up to 1300°C. The temperature can be controlled by adjusting the size of the flame in order to keep the temperature between 200° to 500°C.
How to use gas soldering iron
When using gas soldering iron, first rotate the direction to the right, open the gas switch, you can hear the sound of gas flow and smell a little gas flavor.
At this time, use the lighter against the opening part of the soldering iron head to ignite, and pay attention to observe, soon the inside of the opening part of the soldering iron head becomes red, can be used.
Soldering iron valve adjust the valve size to control the temperature of the soldering iron head, when adjusting the temperature, you can judge the temperature high and low by observing the brightness out of the opening of the soldering iron head.
When closing, the valve will have some delay and the flame will not go out immediately. Be careful not to adjust down too much, or it will be dangerous. There is a small hole at the bottom of the soldering iron for the gas filling place, use the same as the lighter gas filling.
Precautions for the use of gas soldering iron
The head of the soldering iron is made of pure copper as the base, processed by iron plating, chrome plating and tin plating multi-layer plating and become a long-life soldering iron head, do not use a file to polish or change its shape.
Accessories in a variety of models of the soldering iron head, the purchase of the need to choose according to the situation, due to the limited volume of the gas tank, the need to do a good job in the welding of all the preparatory work, and then light the iron, prohibit the long time to ignite the unused. Note that in the welding can not use corrosive flux.
The heated soldering iron can not be placed directly on the table, plastic products and other objects to avoid scalding objects. Do not touch with your hands to avoid danger, prohibit children from playing in the vicinity, enough to cause unnecessary injuries.
After use, after cooling, the gas soldering iron collection.
