A heat gun is a device used to emit a stream of hot air. They are superficially similar in shape and construction to a hair dryer, though they run at much higher temperatures.
Heat guns can be used to dry and strip paint, apply heat shrink tubing, apply shrink film, dry out damp wood, bend and weld plastic, soften adhesives, heat shrink wrap on packaging, and thaw frozen pipes. They are also used in drying stamp powder to make the picture to get relief impression and ***** very good tool for DIY
