A rule of thumb to remember is to use a low temp glue gun if the material you are working on will distort or melt when it comes in contact with too much heat.

So, how low is low temperature for glue guns? Good question. If high temp glue guns work at 380 degrees F then low temp glue guns work at right around 250 degrees F. That means, that the glue stick that you should be working on will be melting into its liquid form around that temperature.

Around great rule to remember when to decide to use low temp glue guns is when you’re working on thin materials and that high temp glue can seep through it and burn you.

Also, did you know that there is such a thing as ultra-low glue guns? Yep, these glue guns are for the elderly or kids. Especially to be utilized on home and school projects. They operate at a low 75 degrees so they should be safe and won’t burn one’s skin at all.

All right, materials such as foam, thin films, fabric, plastics, some cardboards, or card stocks are only a few of the materials that you may work on using low temp glue guns. They are generally known to be safer and have a faster set time.

Did you know that there are variable temperature glue guns and glue sticks? Yep, there are glue guns that you get to decide which temperature to use. And also, there are glue sticks that will melt no matter the temperature the glue gun is operating in.

I hope we’ve shed some light on the old hot glue gun vs cold glue gun debate. Now, let’s discuss a few more important aspects of this topic.
