With the provided pair of pliers, cut a short length of the end of the tips to equal lengths
and to remove any minute factory blemishes on them.
Next, with the file provided in your kit, file off the ends
of the tips to smoothen out any irregularities that might
snag when inserting the tip into the pen’s collets.
Once inserted in the pen, be sure to tighten the collets
with the pair of pliers for proper contact.
Universal tips are designed to go into several models
of wire tip burners. With these tips, it is advisable to
make sure that the tips resemble the original form as
much as possible. You can file/cut/adjust those tips in
any way necessary, but the main goal is to avoid any
buzzing noise emitted by the pen.
