Temperature range from -12°C to -32°C (10°F to -25°F). Recommended iron temp: 155°C (311°F).
The speed of the iron should be approx. 8-10 sec. on a skating or alpine ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. Scrap after approx. 1 minute. It's important to have a good iron to get an efficient melting of the wax.
In the warmer part of the temperature range, and with high air humidity, Cera F powder, such as FC04X will increase the performance.
