This was designed by modifying and integrating the tip of the type U heating element to generate the heat uniformly and enable the input of greater electric power, resolving the temperature decrease at the tip area by doing so. While there is a limit in dimension for manufacturing reasons, the electric specifications are the same as type U. You are recommended to use it in a vertical position, as the tip portion is heated.
