Hot glue high or low temp

If you try to get the heating element to a higher temperature, the plastic of the gluegun itselves will melt and will probably break down. When you are interested in melting plastics, you should consider using an extruder from any 3D printer.

I have never seen an extruder for solder. Things like resin and/or flux needs to be added to have the solder flow correctly and I think you dont want to go that way.

Thank you for atempting to answer my question, however it seems my question was severely misread.

At least where I come from, glue guns come in two different configurations, Hi temp and low temp. My question was does anyone know what Ben uses on the show, hi or low temp?  And does it really matter, specifically when trying to glue things to PCB's?  Would the glue itself possibly be hot enough to screw up existing solder on the PCB, or possibly melt the PCB itself, when using a HI temp glue gun?  Or must a Lo temp be used for gluing to PCB's.

I did indeed misread your question, thanks for the clarification.

When working with PCB's my experience is that the low temperature gun is good enough to do the job. It also depends on the gluesticks you want to use. The low temp sticks are very cheap and work easy. Also with the low temp stick, when you burn yourself, it will hurt a lot less than the high temp guns. The high temp glue gives 3rd degree burns.

When you look at a PCB, it is resisting very high temperatures, 350 degrees did not burn my pcb at all, it might get a little discolored, but the board was not really affected. At these high temperatures it is possible that small traces come loose from the pcb.

When you look at solder, the temperature for 60/40 solder is 190 degree, 63/37 will melt around 180 degree. Leadfree solder has a higher temperature, but is dependent on the metal mixture. For the solder to become liquid, it will need to take +20 degrees above this temperature to really mess up your work. Also when just placing a small amount of glue, it will not have enough capacity to make a differenct.

Al temperatures are in Celcius.

Thank you for your help.

I personally use a dual temperature glue gun. According to the manual, a low temperature is better for fabric, card and other similar materials whereas high is better for wood, plastic and the like. I use the high setting on PCBs all the time with no issues so far.

low temp ok
