Types

• There are three standard types of glue guns: high-temp, low-temp and dual-temp. High-temp guns are generally used to create stronger bonds for materials such as metal and wood. They melt glue sticks at a temperature of 380 degrees Fahrenheit. Low-temp glue guns melt glue at a temperature of 250 degrees, and are often used for fabric, plastic and heavier paper. Dual-temp guns can be toggled back and forth between a high-temp and low-temp setting. A fourth type, cold-heat or cold-temp glue guns, also use heat to melt glue, but cool to the touch much faster than traditional glue guns.
  
  

Function

• Most glue guns operate with electricity from a standard three-pronged wall outlet.electrical outlet image by Mat Hayward from Fotolia.com
  
  Glue guns melt solid glue sticks using a heating element. The glue then drips out the nozzle in liquid form. Some glue guns feed a glue stick through use of a trigger. Others require you to feed a glue stick through the barrel manually. Most glue guns operate using electricity from a standard wall outlet, though some models can be battery powered.
  
  

Size

• Glue guns come in small and large sizes, and require glue sticks of a corresponding size. Your frequency of use and the size of your project should determine which size you choose. Smaller glue guns are often less expensive than full-sized glue guns, and are better suited for detailed application. Larger glue guns will use fewer glue sticks and can apply glue to a broad surface area with ease.
  
  

Benefits

• Glue guns bond materials other adhesives cannot, which makes them beneficial for quick home repairs. They are also relatively inexpensive and readily available from any craft store. Glue guns expel adhesive that dries quickly, which provides for ease of use. Most glue sticks are clear and provide an inconspicuous bond, but they also come in different colors to match your project.
  
  

Warning

• Severe burns can result from improper glue gun use.A hand image by Gryte from Fotolia.com
  
  A 2006 study conducted by the U.S Product Safety Commission indicates that most glue gun injuries that resulted in hospital treatment were burns to the fingers and hands. Most of these injuries can be prevented by following simple safety precautions. Always consult your operator's manual for proper use instructions, never touch the heated nozzle of your glue gun, and always stay focused on your task.
