Description:This item owns large capacity, the use time can be 100-120 minutes each time when there is full of gas. With automatic ignition function and safety switch device, it is more convenient to use. Transparent tail can visually see the gas content. It can used as a common iron, a heat gun when the solder tip is removed, or a flamethrower and the flame size can be adjusted. Suitable for electrical appliance, electrical control box repair welding, jewelry, plastic cutting maintenance industry, etc. Compact and portable size is easy for carrying.Features:Large capacity, the use time can be 100-120 minutes each time when there is full of gas.

Specification:Condition: 100% Brand NewMaterial: Engineering PlasticFlame Temperature: 1300 Tip Temperature: 450 Hot Blast Temperature: 500 Use Time: 30-40 minutesProduct Size: Approx. 24.5 * 13 * 5.5cm / 9.6 * 5.1 * 2.2inchProduct Weight: Approx. 466gPackage Included:1 x Soldering Iron Set1 x InstructionNote:Many customers are using the gas soldering iron for the first time. Improper operation leads to such and such problems. After my own exploration, I try the correct method to see the following content:1. Soldering iron usage skills: first open the valve knob to the maximum 4, and then push it up to the bottom to start the fire (observe the soldering iron core opening turning red) and then slowly release the switch.2. Fire and observe carefully. The inside of the opening part of the soldering iron head should turn red soon.In fact, to adjust the amount of air used to control the temperature of the soldering iron head.When the temperature is adjusted, the temperature can also be determined by observing the brightness of the opening of the soldering iron head.Some customers of the gas soldering iron are using it for the first time, and there is a familiar and groping process. After ignition, it burns for 5 seconds.Do not use soldering iron function when welding continue to raise the gear use, which will cause high temperature and the joint part of the plastic melting.When using soldering iron, use low - grade position can be safe and save energy.3, when using a spray gun, the product temperature up to 1300 (solder iron temperature 400 ) need to pay attention to safety when using, when using spray gun and heat gun with high temperature and the volume is big, the size of the need to control the air output to extend the service life of the iron, the right skills should be depending on the site, such as 1300 flame, such as for 5 minutes continuously burning, will make the plastic part on the edge because of melting away under the heat too long, at this time, due to the close iron and check whether can affect the work, for cooling after use, after finished with shut off switch.Use to pay attention to the maintenance of coning steel-toed, don't turn the switch was used for the first time very big, after the start preheating tin on little point in the low temperature, can be more a few times the size of the master of molten tin switch (generally good tin wire, tin content is high, low capacity of 250-280 degrees can be melt, cheap tin SiDou is usually in the high melting point of 350 degrees to melt) on the tin is tin wire on the welding head head uniform for tin, namely surface containing tin.Then adjust to 300 degrees -350 degrees to weld, as far as possible in low temperature welding, that is to say 350 degrees, 300 degrees, 280 degrees also remember to tin, so as not to expose the soldering iron head in the air oxidation.If the soldering iron in the welding black hair to the heat sponge to rub back and forth after bright tin, to develop such a habit.Heat - resistant sponge should be soaked in water before use and then wrung dry.
