24W 20cm Electric Hot Wire Cutter Foam Polystyrene Heat Cutting Engraving Pen
# Foam Cutting Pen 1. Fast heating for easy operation 2. Cut foam blocks from any angle to shape as needed 3. Smooth, rapid cutting; clean sealed edges without debris 4. Ergonomic non-slip handle for comfortable, stable grip 5. Ideal for cutting, carving and lettering on polystyrene foam ## Specifications Material: Nickel-Chromium Alloy Room temp resistance: 20 Ohms Max working temperature: 1500°C Application: Insulation foam cutting ## Important Notes 1. Pen tip length may slightly differ due to production batches. 2. Single continuous working time ≤30 mins; cumulative usage ≤2–3 hours. 3. Heating tube can only be bent ONCE; repeated bending at the same spot causes breakage. 4. Only suitable for medium & low-density foam; NOT for high-density foam or mass production cutting. 5. Switch off power after use to extend service life. 6. Items undergo power test before delivery; minor foam residues on pen body are normal. 7. Different-length heating pens cannot be mixed with mismatched power adapters, which leads to failure to heat or burnout. 8. For long-hour heavy work, select desktop foam cutting machine instead. ### Power Supply Comparison - Electronic Transformer: Low cost, lightweight and portable. Vulnerable to voltage surges, higher environmental requirements. - Full Copper Linear Transformer: Highly durable, only likely damaged by overload, but higher cost. ### Foam Cutting Pen VS Desktop Cutting Machine **Foam Cutting Pen** Portable; short single operation time; flexible hand shaping for right-angle corners. **Desktop Cutting Machine** High power, replaceable heating wire, low long-term cost and fast cutting. Produces ultra-smooth burr-free cuts. Compatible with high/medium/low-density foam, sponge, KT board. Supports prolonged work. Avoid overnight standby to protect transformer. ## Tip Mark heating tube corners to improve bending precision. Sample shape: 8.5*4.5cm rectangle and rounded rectangle.
