Foamed plastic material are cut, conceived of the blade surface of the electric knife for carving

摘要

(57) [summary] [purpose] the blade surface temperature of the electric knife to facilitate the processing of plastic foam material as like tinged with certain management easy blade surface, and heat control in a variable can be low voltage and high current, use The purpose is to facilitate [configuration] Attach the metal resistor band-like outer periphery portion of the electric knife handle as blade surface, to obtain a constant temperature by passing a low voltage high current from an external control power supply
