Glue Gun Wattage Controls Melt Speed and Heat
A glue gun wattage decides how fast it melts sticks and how steadily it holds temperature. Too low and the gun starves on a production line; too high and you waste energy or scorch delicate substrates. Match wattage to stick diameter and duty cycle.
20W Mini Guns
Low-power 20W guns pair with 7mm sticks for light crafts, electronics, and occasional repairs. They heat slowly and suit low-volume, precision work rather than continuous use.
40W Standard Guns
The 40W gun is the everyday workhorse for 11mm sticks, handling DIY, packaging, and workshop assembly. It reaches working temperature in a few minutes and sustains steady output for moderate jobs.
60W and Above
60W guns and industrial 100W+ tools melt larger sticks (15mm, 18mm, 24mm, 43mm) and keep up with high-output or production use. Choose higher wattage when you bond continuously or need fast re-melt between applications.
Selection Summary
| Wattage | Stick Size | Use Case |
|---|---|---|
| 20W | 7mm | Crafts, electronics, light repair |
| 40W | 11mm | General purpose, packaging |
| 60W | 11-15mm | Assembly, higher volume |
| 100W+ | 18-43mm | Industrial, continuous production |
