Clean the tip regularly with the included brush to prevent debris buildup. Store the device in a cool dry place away from flammable materials.
Frequently Asked Questions
Can I use a hot knife on wood?
While designed for foam and synthetic materials, some tools can lightly mark wood. However, standard blades are optimized for melting plastics and not for cutting wood fibers.
Are replacement blades available?
Most kits include multiple blades but check the product page for specific replacement compatibility. Always verify the attachment mechanism before purchasing additional tips.
How long does the tool take to heat?
Heating times vary from 10 seconds to a few minutes depending on power and temperature settings. Higher wattage models generally reach working temperature faster.
