What are the common problems with gas lighters and spray guns?

How to solve the common problems we encounter when using gas lighters and spray guns? I believe that everyone has encountered similar problems. Let's take a look at the common problems encountered with gas lighter spray guns.







 
Straight-through lighter sprays open flames during use: Generally, the valve is opened too much when the gas is sufficient, and the valve is closed small (generally, lighters can be solved by adjusting the “+” large flame and “-” small flame at the inflation port). ; Another situation is that the gas just added to the gun lighter or the internal pressure of the gas caused by the sloshing of transportation will increase, and it will also cause an open flame at the beginning of use.
 
There is gas coming out of the flame outlet, but the fire cannot be ignited: after pressing the switch, there is gas coming out of the flame outlet, but it cannot be ignited. At this time, close the valve (no need to close the valve for small lighters) and light the flame in a slightly darker environment to see the flame outlet. Is there a spark (look away from your eyes), if there is a spark and the spark hits the outer edge of the crater, use a small screwdriver or tweezers to adjust the lead tip so that the spark hits the metal column of the crater. . After refilling, the flame suddenly becomes larger or smaller or becomes smaller, and the flame becomes larger or smaller after refilling, which is usually the cause of the gas. It can be solved by replacing the gas with high ignition point, high pressure and few impurities. The flame of the straight-through machine becomes soft and the fire becomes soft. The straight-through flame of the portable small straight-through lighter becomes soft after use. Generally, the surface of the metal pagoda of the fire outlet is dirty and blocked. After lighting, blow out the flame and clean it with a small brush or correct it. A few blows hard on the fire outlet solved it. Is it a little artifact.
