Hints On Use

1.I want to use the HAKKO 373 for a different solder diameter.

Change the tube unit, guide pipe assembly, and solder diameter adjustment ring according to the solder

diameter to be used.

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 do not agree with the soldering iron to

be used.
