Once you do so, you can remove any retainer or other parts. Carefully add power to the heating element to let any residual glue melt. How glue gun heating element works? Check the heating element and temperature connections for loose wires or broken solder. The melted and usable glue is then dispensed through a metallic nozzle, which can get significantly hot. The switch can then be installed. Key Features Use a little bit more glue than necessary, because if the wires touch the element it will burn through the insulation and could cause a short. I'm an engineer-in-training based in Melbourne, Australia. Somewhat approximately the 1900 ohms I was looking for. What are the main parts of this glue gun. You can fix a wobbly bench or table with your pocket change. Therefore, a momentary switch MUST be used if you use a heating element of this style. That whole deal was tightly clipped with a steel clip to the alumium housing/nozzle inside of which the glue melts. Looked kind of like brake pad composite material. Remove the silicone caps on both the nozzle and the inlet sides- you want to be working with just the metal piece. . If you look closely, you can see the seams from its molding process. Low-temperature glue guns heat to approximately 250 °F, so they work best for materials that may be vulnerable to heat. It keeps the nozzle close to the place of glue used. I took it apart expecting to find a coil of nichrome like in a soldering iron. If you ever need to remove the glass, just heat the back with a heat gun to soften the glue. THe contacts and the aluminum chank were wrapped in orange cellophone it looked like. To turn stuff on and off, you need, well, a switch. If this is your first glue gun that you are modifying, then this can be held in pace with superglue too, just ensure the LED is a tight fit because superglue has no gap filing properties. A hole must be drilled for the switch- in this case a 12mm one. Most hot glues melt at about 120 C. First thing I would check is the max temp. Finally, reassemble all the silicone parts back onto the heater barrel. After an initial warm up, I found that you could get about 4 minutes of gluing for every minute of holding the button down, which is very usable. After the thermal adhesive had dried, the resistance wire was then wrapped around the barrel. Firstly, we need to reinstall the trigger assembly. Measuring the resistance of the whole glue gun, cold, at the prongs of the plug, the resistance is around 1900 Ohms. Looking for MASTER APPLIANCE Heat Gun Element Kit (1A503)? 4 years ago. This was only glued on the bottom, so that the glue gun can still be disassembled (just in case). Share it with us! As this occurs, less current flows, and the element cools. And why are you here? Congrats on your first instructable! I'm not super satisfied with the way I wired up the LED, as it is only on when the button is on. The closest wire-wound resistor I could find has a resistance of 10 ohms, giving (from the previous formula) a power consumption of 14.4 watts. Voltage or Wattage Glue guns can often operate in 100 to 120 watts, which is enough to do your task. Grainger's got your back. Since this hot glue gun was designed to run off of the12 volt circuit of a car, a cigarette lighter plug makes perfect sense as a power connector. The same thing (two different wires) was done to the second pole of the switch, one for the LED and one thicker wire for the heating element. The gun shape is useful in allowing the user to use a trigger action to force the stick through the heater, but not necessary for the actual application of glue… Hot Glue Gun 50W Tilswall Mini Melt Gun. First of all how is it the same wattage at 120 and 240 volts? The two thicker wires were then soldered directly to the heating element. Electronic devices tend to not work very well without a way of actually getting electrons into the circuit! Did you make this project? You can push the trigger after heating to get the glue. White light is probably more useful than a coloured LED, but not as aesthetic! This is a very good thing for a resistor, but not for a heating element. Another question. I left the power connected for 3 minutes and the barrel heated up to over 250 degrees! In this video we are showing how to make hot gun glue stick at home how to reuse your remain glue stick or used hot glue. It's basically just a heating element surrounding a tube through which the glue stick is pushed, and a nozzle. To work out the required resistance, we can substitute ohm's law into the power equation, giving us r = (v^2)/P. Get your glue gun heated up and start filling the molds with glue! Since I wanted this glue gun to run off of 12 volts the resistance can then be changed to give the power required. Now, I hope you saved the kapton (polyimide) tape that was wrapped around the 240 volt element. About: Hi all! You can now use your control circuit to adjust the output of a heating element and control its temperature. To ensure we don't release the magic smoke, there are two things to consider: what voltage is being used and how much power you want converted to heat. Think a little piece of cellophone big enough to wrap up the paddles with that little chunk of aluminum between them. Hot glue (or superglue if this is your first hot glue gun) can then be used to route the wires, ensuring they cannot touch the heating element. The only way (I found) to remove the strain relief from the cigarette lighter socket it to cut it away from the cable its attached to. I wouldn't think it could be. This means a constant power flows, and so the element doesn't cool down. The top countries of suppliers are China, Taiwan, China, and Vietnam, from which the percentage of glue gun heating element supply is 99%, 1%, and 1% respectively. On the package it said: 10 watts, AC 120-240V. If you use a thick knife (box cutter etc), you are left with a wide gap that is not too pleasant to look at! Keep in mind that the glue must dry before strength is significant and the project often. This ensures the element cannot be left turned on, and reduces the risk of fire and other heat-related accidents. A cigarette lighter plug was purchased- I got one that came with a fly lead attached, terminated to a 2.5mm DC socket- but because I didn't want a removable cord, and wanted the build to look neat, I had to modify it. Here are some resistance vs temperature curves for TDK Series B59102 PTC heating elements, which are designed for use in home appliances such as hair curlers and glue guns:- . First of all how is it the same wattage at 120 and 240 volts? This is where I made the mistake, as the switch was installed right where one of the screw holes was! It's quite simple! However, I did end up shortening the resistance wire a bit when it was wrapped around itself, giving a resistance of 9.03 ohms. The diagram above shows a typical hot glue gun. If you’re a crafter like me, a glue gun is one of your favorite crafting tools. Well, yes, but that rating is when the resistor has no additional cooling. Not that I know from experience or anything.... Next, the other side of the glue gun case can be reinstalled. This Video Show How To Open Hot Glue Gun Which has Two Heaters 60W + 40W = 100W , Switch Provided to select single 60W Heater & Both 100W Heaters. Easy! It must be that thin cellophane wrapper no? The heating process is regulated by thermistors, which allows the glue to be heated without the rest of the gun becoming hot and burning the user. Thank for taking the time to read my first instructable, I hope you learnt something or gained a few ideas of your own! It heats up in 45 seconds? These are very hard to clean. I wish mine would heat up that fast! It is a very easy (and inexpensive) task to make one yourself, and you get a pretty cool and useful tool to play around with too- so why wouldn't you want to build one! I've got this little glue gun. The case was screwed together for this- ensuring the hole was centred and keeping a high quality look. I took it apart expecting to find a coil of … Buy on Amazon. Then, glue the strain relief halves around the conductors of the mains cable. Ever wanted a semi-portable hot glue gun? I measured the resistance, 2500 Ohms. Finally, refit the top case half and screw in the remaining screws. This insulates the barrel from the resistance wire. What am I missing thats creating 1900 Ohms of resistance? 240 volts AC is only dangerous if you work on the glue gun whilst it is powered. Then, cut off the mains connector and strip this length from the cable's outer sheath- DO NOT cut into the insulation of the conductors inside, as they will be next to each other inside the strain relief. Although not necessary, a light is a good thing to add, and the ease of doing this with a voltage as low as 12 makes it a no-brainer to install. Instead I found that the power cord was soldered to two inch long twisty tie wire looking, insulated wires. After you get in, the trigger assembly has to be removed to access the heater barrel and the (no longer wanted) 240 volt AC heating element. If it gets about 210-220 C then you could use it to extrude PLA. Obviously, there are some basic tools you will need too: Scalpel (or a really ridiculously sharp and thin knife), Phillips screwdriver (or whatever bit you need to disassemble your donor hot glue gun), Superglue (cyanoacrylate) or similar adhesive, A second, working hot glue gun (but you can get away with insulation tape). But wait, I hear you say, isn't that resistor only rated for 10 watts according to its own label?!! This lowers the resistance, and the process repeats again and again. Let’s kick off this list with the Cobiz Glue Kit which offers a heating element that can … It just means the button has to be held down to supply power to the heating element. A push-to-make switch must be used- this will send power to the heating element only when it is actually pressed. The 240 volt heating element has a positive thermal coefficient- as the temperature increases, so does the resistance. then Sandwiching that were two more flattish rectangular pieces of aluminum. It is, however, possible to do this on an older glue gun, it is just simpler to do if the glue gun is clean. By substituting the given values, this give us a required resistance of 10.2857 ohms. Glue guns should be switched on at least five to ten minutes before they are used. It looked shiny but I think that was thermal paste. After you get in, the trigger assembly has to be removed to access the heater barrel and the (no longer wanted) 240 volt AC heating element. This is fairly simple to do, as its mounting method shouldn't have changed from when the glue gun was new, and should just slot together. UniQual Low Temp Glue Gun has better ergonomics design for kids. This is because hot glue in general is a useful adhesive- it is waterproof, relatively strong, can be removed (with effort) and is quick drying. This allows the heating element and the glue next to it, to heat up. Firstly, the previously calculated resistor can be soldered directly to the LED's positive pin (the longer one, or the rounded side). Thanks Info-Sam! Something that probably should have been checked before mounting the switch, and I would recommend you do the same. If the heating element is already reaching 120 C, at highest possibly, then there is a good chance you can get it up to the necessary heat … It is very well written with clear, in-focus, photos. These two inch long sections of wire had two little paddle contacts on the end and between them was a little rectangular chunk of aluminum. Why not build one? 240 volts AC is only dangerous if you work on the glue gun whilst it is powered. 244 ptc heating element for hot glue gun products are offered for sale by suppliers on Alibaba.com, of which electric heater parts accounts for 11%, heating equipment accounts for 1%. The switch specified at the start is rated for 3 amps. The LED I used has a forward voltage of 3.4 volts, and a forward current of 20mA, or 0.02 amps. Almost done! 5 years ago. The final part is to strip the ends off the actual wires and solder them to the positive and negative contacts of the cigarette lighter plug, and then reassemble the cigarette lighter plug. I guess I left out the orange cellophane wrapper in the picture. Hold up, what I thought was a little chunk of aluminum between the paddle contacts, I now don't think is aluminum. Fix something while your camping? It's because I'm putting in more than twice the heating power (21 watts vs 10 watts) compared to how the glue gun was out of the box. I also added some extra kapton tape around the heating element later, to help insulate even more (not shown). High-temperature glue guns heat to approximately 380°F and work well for projects that require stronger bonds. The forums are retiring in 2021 and are now closed for new topics and comments. Hot glue is most commonly applied using a glue gun and comes in low . To remove it, simply cut down those lines. I wouldn't think it could be. Expensive hair dryers, space heaters, and of course-mini glue guns from the dollar store. I have listed the components (and prices) from Jaycar electronics here in Australia (to support a local business) but I am sure you can find the same parts online if you can't find any at your local electronics store. You can go through an entire stick of glue at once after heating it up, without touching the button, if you so wish! Then, tape the cone on top of a candle lighter so the tip just extends past the lighter. I love taking stuff apart to see how they work, as well as hacking stuff to make it work even better! Answered. The LED was glued in with hot glue. Done! Although not strictly necessary, removing this gives more room in the case of the glue gun. I dont know though...It just looks like a little chunk of metal. I saw a current draw of 1.323 amps at 12 volts, for a power consumption of 15.889 watts. Add enough of them, like in the hand warming mouse or in a blow drier, and they will put out an ample amount of heat to increase the temperature of the glue gun to melt solder. I found that the strain relief on the cigarette lighter plug looked easier to remove- so that's the one I worked on. One of these is a thicker cable for the heating element, and the second is a length of thin (30 AWG) wire to power the LED. Hot Glue Gun Uses: Fix Wobbly Furniture with a Penny. Be careful- it is quite thin and easily broken. In the end I decided on a power of 14 watts. Let me know in the comments if you used any of the ideas presented here in any of your own projects! The thinner positive and negative wires can then be soldered to the LED, ensuring the polarity is correct (positive to the resistor, negative to the shorter leg/flat side). It is much nicer to use hot glue when it heats up quickly! You could, of course, use any colour you like, I just happened to have a 5mm high brightness cool white LED on hand. It must be rated for at least the maximum current of the heating element, in this case 1.52 amps. Instead, I tried using hot glue to fill the hole. This makes it heat up really quickly and is very useful! if you leave a hot glue on overnight --- the glue gun stays on all nightANS 2 - All the glue will get really liquid and leak out and the heating element may burn out. However, if the resistance is too high it will not heat up enough, and if it is too low too much power will flow, resulting in too much heat (and leading to the magic smoke being released). Help? Remove all the screws- you want to be able to take the cover plates off. See link here: http://dgbizhuo.en.alibaba.com/product/1485338659-... Answer You could use wood filler, epoxy, bog or a specially designed product, but I didn't have any of those to hand. Thus, the voltage dropped across the resistor must equal 12 - 3.4 = 8.6 volts. It is much easier (and safer) to work on when the glue gun is cold and there is no glue inside the barrel of the glue gun. 2 years ago, Answer The Tilswall hot glue gun is built to last a lifetime. First, a rotary tool can be used to rough up the plastic and to neaten up the hole. Next, the LED is wired up. Best Budget, Mini: CC Better Mini Glue Gun.

Maybe ceramic? I did not put any heatshrink over these connections, as the maximum temperature of heatshrink is normally 180 degrees Celsius, whereas in extreme circumstances the heating element could be double that. Now, we did work out a power consumption of 14.4 watts. The first part here is to ensure that the modified barrel fits into the original slot. I am guessing that most glue guns are not going to get this hot. Donor hot glue gun- 7mm sticks use less energy to melt- Part number TH-1997, cost: $12.95, Cigarette lighter plug- Part number PP-2008, cost: $4.95, Push-to-make switch SPST (momentary, must be rated for am least 2 amps)- Part number SP-0741, cost: $1.95, Current limiting resistor- suitable for the LED you use, 10 watt wire wound power resistor- Part number RR-3352, cost: $1.80, Heat shrink tubing (not essential but nice to have), Thermal adhesive (not essential but makes assembly easier)- Part number NM-2014, cost: $7.95, Total cost (not including LED and thermal adhesive): $21.65. 18 / 19. If you forget this you will forever be wondering (and cursing) why the new glue sticks keep falling out of the back of gun. The wanted component is the cable strain relief, from either the cigarette lighter plug or from the 240 volt mains cable (that came with the original hot glue gun). It is a very useful thing to have that not many people actually think about! If you do end up with excess glue, use an … My question is-where is the resistor here? I had to remove a part of one of the screw posts at the top (as the new heating element increases the thickness of the barrel), but be careful to not cut into the threads, or the screw cannot be secured properly. However, remember the 80% rule, such that you don't use more than 80% of a given component's capacity. Make sure you don't damage the kapton tape wrapped around the element as it is reused to make the 12 volt heating element. The aim is to remove the strain relief from the red and black wires that the cigarette lighter plug comes with and install the strain relief on the sheathed cable that comes with the hot glue gun. Answer Yes, I know you can buy them off of Ebay and the like, but if you do there will be a couple of months wait, and they are about the same price as this one. APO hot melts have good fuel and acid resistance, moderate heat resistance . A step drill ('Christmas tree bit') makes neat work for this. Try not to overflow the mold and/or have excess glue on the edges. Add the stand and you're done! The gun uses a continuous heating element to melt the plastic glue that is then extruded through a tip or nozzle when the user applies pressure to gun's trigger. High temperature electrical insulation. However, sometimes I need to get into a tight space or only use a little, thin strip or dab of glue. I tried to cover the basics from choosing a glue gun to more advanced questions like can you use hot glue sticks for mold making. Finally, remove the metal clip that holds in the heating element. The power of the heating element means it doesn't have to be held for long to get hot enough to glue stuff. A wide variety of heat glue gun options are available to you, such as application, temperature type, and glue stick length. The positive wire (connected to the tip of the cigarette lighter socket), was then soldered to one pole of the switch. The nearest value I had on hand is 470 ohms, so this value will be fine, giving the LED a current consumption of 18mA. To make a glue gun, start by slicing the top and bottom off a soda can and cutting the tub open to form a flat sheet. MAKE SURE THE GLUE GUN IS UNPLUGGED! The power consumption of something like this, with very low resistance, will change quite a lot with small changes in voltage- I measured 1.323 amps at 12 volts, but 1.52 amps at 13.8 volts! If you have followed this instructable, you will now have yourself a working 12 volt powered hot glue gun! In the future I may end up rewiring the LED, so that it is on whenever the glue gun is connected to 12 volts, which should be much more useful. All you need is a source of resistance and a flow of electrons though it. Then, blue painters tape (but really any low-tack tape, can be used, but ensure it is low tack or you never get it off) to cover the hole from outside the case. Found out it's a PTC element. Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun.The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure.
