This unit may be a little more than most people want, but it’s the best there is. The gun is cordless, allowing you about 20 minutes of work time between charges and there are also four separate adhesives made for it, allowing you to pick the right adhesive for the application. Unfortunately, the adhesives are not standard hot melt glue sticks, but specialty adhesives made by Titebond, the same company that makes the excellent wood glue. A ball check valve in the tip keeps the gun operating dripless, eliminating a problem common to using hot melt glues. This glue gun comes in a convenient carry case with as assortment of adhesives and a stand/charger.
This unit from Ellsworth Adhesives is a true professional glue gun, with a 220 watt heating element that allows it to put out as much as six pounds of adhesive per hour. That's using standard 1/2 inch diameter glue sticks, from 4 inches to 15 inches in length. If you need to do a lot of gluing, this unit will provide that capability at a very reasonable price. The temperature is adjustable from 155.5 to 215.5 degrees Centigrade (312 to 420 degrees F). A four finger trigger reduces fatigue and a built-in stand is provided for convenience.
If the first two units on the list are a little too rich for your blood, take a look at this model from Surebonder. While still considered a professional gun, it is priced along the lines of top-end consumer guns. With 80 watts of heating power, this gun will still melt through a lot of glue, although not as much as the Bostik unit. It is dual-range, with preset temperatures of 250 and 380 degrees F. This gun uses 7/16 inch glue sticks, which are available in 4 inch and 10 inch versions. Interchangeable nozzles help you customize the gun to your specific needs, specifically how much glue comes out of the nozzle when you pull the four-finger ergonomic trigger. A removable wire stand is included.
This consumer gun from Adhesive Technologies sports a 60 watt heater, outputting two pounds of adhesive per hour. That's still double what most consumer grade glue guns can put out, the equivalents of 82 glue sticks. This is a single (high) temperature gun, running at 380 degrees F. The tip is insulated to protect you from accidental burns. An integral on-off switch allows you to turn it off, without having to unplug it. An indicator light provides you with a clear indication of whether the unit is on or not. This glue gun comes with two stands, a flip-up small stand at the tip, like the other guns we've looked at, as well as a larger stand attached to the base of the handle. The trigger can accommodate four fingers for most people.
For those who need a glue gun for hobby and craft use, Arrow produces a very nice gun. A switch on the handle allows choosing high or low heat. The two-finger trigger is sufficient for crafts projects and small repairs while a flip-down stand allows you to set the unit upright on the workbench when not in use. A plastic covered nozzle helps prevent burns and is designed to be non-drip.
