This was designed by modifying and integrating the bridge 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 bridge area by doing so, this results in better temperature uniformity in the elements heat dissipation. While there is a limit in dimension for manufacturing reasons, the electric specifications are the same as type U. It is recommended to use this type in a vertical position, as the tip portion is heated.
