•【SPRING-LOADED SAFETY TRIGGER SWITCH】: Because the hot knife cutting tool can reach the working temperature in a few seconds, the spring-loaded safety trigger switch can effectively avoid the danger caused by too high temperature. In order to improve the service life, we do not recommend working for a long time (Notice: Use the hot knife use at 15-second intervals and allow it to cool for about 15 seconds in between!).
•【WIDE APPLICATIONS】: Foam cutter usually used for packaging, construction, pitched roof insulation, external wall insulation composite system. For professionals, craftsmen or DIY enthusiasts to provide better help in commercial and industrial use. Foam cutter can cut lightweight foam, KT board, polyurethane, polyethylene, EPS, XPS, EPP, EVA, EPE, PU, polyester foam, sponge, rubber, nylon and fiber, etc.

Styrofoam cutter can give you the same experience as cutting butter and bread with a knife. The cutting process is very smooth, and the cutting effect is flat and perfect.
•【ADJUSTABLE TEMPERATURE】: The adjustment knob on the top of the foam cutting tool has 16 positions to adjust temperature and power. The wide adjustment range can meet the needs of most industries and jobs. The wider the scale on the knob, the greater the power and heat. If you can't master the temperature control temporarily, we suggest you practice several times on the foam waste (NOTICE: If the red light flashes after pressing the switch, push the adjustment knob forward to increase).
