Pls make sure you don't mind before you bid. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!Instructions note:When you use this item, the first right direction, open the air switch, then you will hear the sound of gas flowing, and you will feel a little taste of gas. At this time, you can use a lighter to aim at the open part of the cast iron soldering head to ignite, and then pay attention to notice that the inside of the hole of the cast iron soldering head should quickly turn red. At the bottom of the soldering iron temperature control twist selection, the actual amount of gas used to adjust the temperature tip control. Adjust the temperature and also observe the brightness of the tip hole to determine the temperature level. When the valve is closed, there is a certain delay, the flame will not be extinguished immediately, and the attention should not be too great, otherwise it will be very dangerous. A small hole in the bottom of the soldering iron for the filling department when used with our lighters adds the same thing.
