Smooth Speed Adjust
The ability to smoothly change the feed rate of the material. The speed adjust allows you to set the mode of operation of the pen to the circumstances: for example, a low speed will be convenient for fine work, and a high speed is so for large elements. Specifically, the smooth speed adjust is convenient because it allows you to select almost any speed in the range from minimum to maximum.
In addition to this type, there is also a step adjustment, for more details, see “Number of Speeds”.
Number of Speeds
The number of fixed speed settings provided in the pen. This spec is specified only if there is more than one such setting.
The speed control allows you to adjust the mode of operation to the circumstances: for example, a low speed will be convenient for fine work, and a high speed is so for large elements. And the more speed settings there are in the pen, the wider the choice for the user to configure the device more accurately. In the most advanced models, the number of speeds can reach eight.
Note that the speed adjust can be not only stepwise, but also smooth (see above).
Display
The availability of a
built-in display. Usually, these are the simplest single-colour screens that display the basic operating parameters — speed and/or temperature. However, even such a display makes the pen more convenient and allows you to get important information about its operation.
Stand
The availability of a special
stand for the pen. In models with hot operation (see "Product Type"), the stand is usually made of heat-resistant materials, and even a heated pen can be placed in it. This is much more convenient, and most importantly – safer than putting the device on the table without any stand or using improvised devices.
