The presence of a regulating element
Surprisingly, some companies release a product without this component, so they reduce the cost. However, it is best to buy products where the presence of a flame regulator is provided because it is more convenient to work with it.
Flame type used
There are several options – vortex, pencil, multipurpose. The first is designed for quick surface heating, the second is used for spot soldering, and the third is needed for people who do not need high temperatures. Therefore, everything here also depends on the requirements of the user himself.
Fuel tank capacity
The volume depends on how long the product can work without recharging.
What causes the ignition
There are two models with and without piezoelectric elements. It is preferable to buy the first option, as it is more convenient and practical.
