If you’ve ever shopped for a hot glue gun, you may have noticed the wattage listed on the box or product description, like 10 watts, 20 watts, 40 watts, or even up to 800 watts. But what does wattage really mean, and how does it affect your crafting or projects?
Whether you are a DIY enthusiast, hobbyist, or professional, understanding glue gun wattage and temperature can help you pick the right tool and get better results. Let’s break it down.
What Does Wattage Mean in a Glue Gun?
Wattage is a measure of electrical power. For glue guns, it determines how quickly the glue melts and how fast the gun can recover between uses. Higher wattage means the glue gun can keep up with continuous use, maintaining a steady flow. Wattage does not determine temperature; that is set by the glue gun type: Low Temp, High Temp, Dual Temp, or Cool Shot.
Temperature vs. Wattage
Temperature affects how hot the glue actually gets and how strong the bond will be:
- High Temp: ~380°F, strong bonds for wood, metal, and thick plastics
- Low Temp: ~300°F, safe for delicate materials like foam and fabric
- Dual Temp: Switchable between high (~380°F) and low (~300°F)
- Cool Shot (Ultra-Low Temp): ~250°F, perfect for kids and very delicate crafts
Keep in mind: the wattage of your glue gun controls how quickly the glue melts and flows, while the temperature determines how strong the bond will be and what materials are safe to use.
Super-Low Wattage Glue Guns (10 Watts)
Cool Shot (Ultra-Low Temp, 250°F)
Designed for younger crafters and very delicate materials, the Cool Shot melts glue slowly and stays at a safe, low temperature.
- Pros: safe; precise control; ideal for kids and delicate crafts
- Cons: Weaker bond; limited to very light applications
Check out our Cool Shot 10W glue guns for safe, controlled crafting.
Regular 10W Guns (Low, High, or Dual Temp)
These 10W guns have the same low wattage, but offer higher temperature options for stronger bonds on more durable materials while still being low-power.
- Pros: Stronger bonds than Cool Shot; safe for small projects; low power for controlled glue flow
- Cons: Slower glue flow than higher wattage guns; careful with delicate materials if using high temp

Low Wattage Glue Guns (20–40 Watts)
Best for Small Crafts, Delicate Materials, Beginners
20–40W glue guns heat faster than 10W models and maintain a steadier glue flow. Ideal for scrapbooking, paper crafts, and small DIY tasks.
- Pros: Safer heat; easy to control; works with mini glue sticks
- Cons: Not suitable for heavy materials; slower for larger projects
Explore our 20W mini glue guns and 40W full-size glue guns for controlled crafting.
Medium Wattage Glue Guns (60–80 Watts)
Best for DIY Projects, General Household Use, Hobbyists
60–80W glue guns melt glue quickly and maintain a consistent flow, making them ideal for a variety of materials like wood, plastic, and fabric. High wattage helps you work continuously without waiting for glue to remelt.
- Pros: Fast glue recovery; stronger bonds for most projects; versatile
- Cons: Slightly heavier; more glue flow to manage on fine details
Check our 60W full-size and mini glue guns for everyday use and DIY projects.
High Wattage Glue Guns (100 Watts and Up)
Best for Professionals, Heavy-Duty Construction, Industrial Applications
100–800W glue guns provide continuous, fast glue flow. Perfect for large projects, thick materials, and professional use. Use the high-temp setting for strong bonds.
- Pros: Fastest glue recovery; strong bonds for demanding materials; professional-grade
- Cons: Harder to control for delicate work; intense heat can damage thin materials; usually larger

How to Choose the Right Wattage and Temperature
- Delicate crafts or kids: 10W Cool Shot (~250°F)
- Small, detailed crafts: 10W regular or 20–40W, low temp (~300°F)
- Everyday household repairs or general crafting: 60–80W, high temp (~380°F)
- Heavy-duty work or professional use: 100W+, high temp (~380°F)
Keep in mind: the wattage of your glue gun controls how quickly the glue melts and flows, while the temperature determines how strong the bond will be and what materials are safe to use.
Final Thoughts
There’s no one-size-fits-all glue gun. Understanding wattage and temperature together lets you work efficiently and safely, creating strong bonds for every project.
