10 in 1 Portable Automatic Gas Ignition Cordless Welding Torch Kit Welding Tool Soldering Tool Kit Description:This item owns large capacity, the use time can be 100-120 minutes each time it is full of gas. With the function of automatic ignition and safety switch, it is more convenient to use. The transparent tail can visually see the gas content. It can be used as a regular iron, a heat gun when the soldering tip is removed, or a flamethrower and the flame size can be adjusted. Suitable for electrical appliance, electric control box, welding repair, jewelry, plastic cutting industry maintenance, etc. compact and portable size is easy to carry.

Specification: Condition: 100% Brand New Material: Engineering Plastics Flame Temperature: 1300 C Tip Temperature: 450 C Hot Blast Temperature: 500 C Usage Time: 30-40 minutes Product Size: Approx. 24.5*13*5.5cm/9.6*5.1*2.2 inch Product Weight: Approx. 466g Package Included: 1 x Soldering Kit 1 x Manual Note: Many customers use 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 skill application: first open the valve knob to the maximum 4,, and then press it down to start firing (observe the soldering iron core opening rolling red) and then slowly release the switch.2. Fire and watch carefully. The inside of the opening part of the cast iron soldering head should soon turn red. In fact, to adjust the amount of air used to control the temperature, cast iron soldering head. When the temperature is adjusted, the temperature can also be determined by observing the brightness of the hole of the cast iron soldering head. Some customers of gas soldering iron are using it for the first time and there is a familiar and grope process. After ignition, it burns for 5 seconds. Do not use the soldering iron function when welding continues to raise gear usage, which will cause high temperature and the common part of melting plastic. When using the soldering iron, the use of low-quality items can be safe and save energy.3, when using the spray gun, the product temperature up to 1300 C (soldering iron temperature 400 C) should pay attention to the safety when using, when using the spray gun and heat gun with high temperature and volume is large, The magnitude of the need to control the air output to prolong the service life of the iron, the relevant skills should be according to the place, such as the flame 1300 C, such as for 5 minutes of continuous burning, It will make the plastic part on the edge due to too long melting under heat, at this time, due to the close iron, and check whether it can affect the work, to cool after use, after finish with the circuit breaker. It is used to pay attention to the maintenance of steel-toed coning, do not turn the switch for the first time very large, after the start to heat tin at a small point at low temperature, it can be more several times the size of the master molten tin switch (generally good tin for soldering, Tin content is high, low capacitance 250-280 degrees can be melted, cheap tin SiDou is usually at high melting point 350 degrees to melt) on the tin is tin for soldering on welding head uniform for tin, namely the surface containing tin. Then adjust to 300 degrees-350 degrees for welding, as far as possible in low-temperature welding, that is, 350 degrees, 300 degrees, 280 degrees also remember the tin so as not to expose the cast iron brazing head in air oxidation. If the soldering iron in welding the black hair into a heat sponge to rub back and forth on the light can to develop such a habit. The heat-resistant sponge should be soaked in water before use and then wrung out.
