Gas soldering iron 3-in-1 multifunctional auto-ignition adjustable flame butane iron with hot flamethrower The product is shipped based on the color or size of the main image of the product page. Gas Soldering Iron 3-In-1 functional Auto-ignition Adjustable Flame Butane Iron with Hot Gun Flamethrower for Jewelry Circuit Board : 1 purpose Soldering Kit: soldering iron is ideal for electrical and jewelry repairs, circuit board, soldering and silver soldering, etc. 2Easy to Use: The soldering iron runs on butane gas and uses cordless operation. It is equipped with a self-ignition spark and its flame is adjustable that can be adjusted to 1/2 to 1 inch in length during use. 3Gas Container city: The soldering iron with 26ml capacity, it can fast heating and heats faster than iron with a plug. inflation lasts about 50 to 100 minutes, which depends on use. 4Transparent : The tail of soldering iron is transparent so that you can see the gas content directly. 5Auto-ignition Function: The feature of this soldering iron is auto-ignition and the player does not need to fire by a lighter, convenient to use Description: Be sure to pay attention to the maintenance of the soldering iron head for the first time of use. adjust the s too large for the first time of use. At the beginning, it should be opened at a low temperature to tin. (The high quality tin wire has a high tin content and can be melted at a low capacity of 250-280 degrees. The cheaper tin wires have high melting points and generally can be melted at 350 degrees.) To tin is to evenly place the tin wire on the head of the soldering iron, that is, making its surface contains tin. Then adjust to 300-350 degrees to weld, but try to control welding at low temperature, that is to say, 350 degrees, 300 degrees and 280 degrees all can weld. Everyone knows that high-temperature welding will burn the tip of the soldering iron, which is oxidized and will be scrapped. soldering, remember to apply tin to prevent the tip from oxidizing in the air. If the iron of the soldering iron is dark during soldering, it must be polished back and forth on the heat-resistant sponge and then tinned. It is necessary to develop such a habit. The heat-resistant sponge must be soaked in water and wrung out before use. : 1. High capacity, 100-120 minutes for each full gas use. 2. The transparent tail can directly see the gas content. 3. boxed storage box. 4. functions: firstly can be used as a normal soldering iron, secondly can be used as a hot (for heat shrink) when the soldering iron head is removed, thirdly removed the entire heating core then it can be used as a flamethrower, and the flame size can be adjusted. s: Material: Engineering Weight: about 460g Outer packing: about 24.5*13*5.5cm/9.65*5.12*2.17in Flame temperature: 1300 C Tip temperature: 400 Hot air temperature: 500 Gas capacity: 26ML Use time: 50-120 minutes (depending on the use situation) : product is equipped with an auto-ignition function, so players do not need to use a lighter to ignite. ing and use, the product is generous and beautiful.
