NEW DESIGN - Side view allows you to observe the internal operation at any time - Heating core can be replaced in the future - Stainless steel housing is corrosion resistant and durable SINGLE-HAND OPERATION - Feeds solder wire through a stepper motor, enabling one-handed soldering without using the other hand to feed wire - If the solder wire jams or needs replacement after stopping, press the plate up and remove the wire EASY TO USE - When used for the first time, it requires a few minutes of warm-up - It is normal for some smoke to appear, which disappears after a short time - Straighten the solder wire, press it into the inlet, feed from the inlet until it touches the tip of the soldering iron - Stop feeding until the wire reaches the opening of the wire guide, then pull the trigger and it should operate correctly INTEGRATED POWER SWITCH - Includes an integrated mains switch for energy efficiency and safer operation - Reduces the need to frequently plug and unplug the device
