Automated solder feeding and solder/flux splash prevention
	Minimize solder and flux splash As shown below, when solder is cut with a V-groove it enables the release of gas pressure generated by the flux, thereby suppressing splash. However, because the V-groove exposes the flux to outside air the solder cannot be stored for a long period of time. When using solder with the HAKKO 374, you can groove the solder that you require.

Hints On Use

1.	I want to use the HAKKO 374 for a different solder diameter. Change all of the driving/following pulley assembly, supply nozzle, guide pipe assembly, and tube unit.
2.	I want to change the soldering iron used with the HAKKO 373/374. Change the iron holder, guide pipe assembly, and tube unit if they are not compatible with the soldering iron to be used.

How to use

	What advantages does the rewind function have?
If the solder remains near the tip after soldering, the heat from the tip will cause it to melt, which in turn causes the flux on the end of the solder to splash or results in or excessive solder feed due to solder beading. The rewind function is designed to help avoid these issues. This mechanism ensures smooth, trouble-free soldering work. The length of solder that is rewound can be adjusted by inserting a flat-bladed precision screwdriver into the adjustment hole on the side of the soldering station.
The length of solder rewound can be adjusted between 0 mm and 5 mm. Make sure that the length of solder rewound is always shorter than the length fed. If the rewind length is longer than the feed length, the solder will be completely rewound.
