Arm Axe Tip Pen Soldering Iron 200W Usage And Feature After the pen is plugged into the soldering iron outlet, the place to be soldered is heated with soldering iron.

Then, the solder wire is applied to the area and melted.

The place to be soldered has to be cleaned in advance, if necessary, it has to be sanded with fine sandpaper and as much space has to be opened as the handle of the solder.

Heating of the soldering iron is done by means of a resistance made of a chromium-nickel material.

Since they are small and strong, their resistance is high and their current values are low.

The hand-holding part of these tube soldering irons consists of three main parts, the electric cable and the tip.

The tip of the pencil (resistance) soldering irons is connected to the soldering iron body by means of a screw.

The length of the pencil tip can be adjusted by expanding and tightening the screw, so that the soldering iron tip can be heated faster or slower.

the longer the tip, the less the soldering iron heats up.

Allow to cool after use.
