Other common applications include: heating elements (hair dryers, ovens, toasters, kilns), model and high power rocket motor and recovery ejection charge ignition, heat sealers, poly cutters, foam cutters, resistors, rheostats, current-temperature controls, pyrotechnic ignition, lab inoculating loops, release mechanisms, ceramic support in kilns... Package included: 3 x heating wire Notice -Please stretch this heating element coil before connecting it to power, or it would burn and cause damage. -Do NOT cut the heating wire into pieces, the shorter heating wire, the stronger power. (eg. Cut one 1000W heating wire into two, each heating wire will turn to be 2000W.)
