Common Questions and Answers About Hot Glue Guns

Every glue gun uses a specific sized glue stick. 1/2" hot glue guns are the most common offering a huge selection of glue stick options that can meet most application needs. For more demanding applications, look for larger glue stick sizes or pneumatic glue guns that offer air assistance. 

Hot glue guns work by heating up a glue stick until it melts, then applying the liquid adhesive through a nozzle onto the surface to be bonded. The heat is generated by a heating element in the gun's nozzle or barrel. Hot glue guns are quick and effective for bonding a variety of materials, but safety precautions should always be taken to prevent burns or injuries.


There are three basic types of glue guns when it comes to temperature, high temperature, low temperature and variable temperature (sometimes called adjustable). 

  • High temperature glue guns: are the most common and usually dispense at around 350 Degrees F. 
  • Low temperature glue guns: dispense around 250 Degrees F and are good when dealing with heat sensitive substrates or to reduce the risk of burns. 
  • Variable temperature glue guns can be adjusted, usually between 220F and 450F, and can be used with high or low temperature glue sticks.
