Refuse filament waste: If the filament is disconnected during printing, or there is surplus material after printing, which is not enough to print a model,it can be connected to continue printing.
Print models in multiple colors: Different colors of the same filament can be connected to print out a multi-level model
Suitable for: Wide range of applications for most 1.75mm filaments: PLA/ABS/PETG/PC/PP/PVB/HIPS, etc
Filament Welder Connector material: All-metal 3d printer filament connector using all-metal materials, high-quality, innovative design, easy to use
Note: Light wire exposure to the air for a long time will often be water loss and brittle. To prevent the filament from becoming brittle, seal it

How to use

Trim the two filament heads that need to be connected.
One end pass-through from the big end of the connector to expose 1-2mm.
The other end pass-through from the small end of the connector to expose 1-2mm.
Burn with fire for 5-7 seconds. (This time is mainly for ordinary PLA , ABS other harder filament should be slightly longer).
Then quickly push the filament from the small end into the small hole at the big end, slowly (must not be fast).
Then slowly pull back when the joint is exposed, back and forth several times.
After the filament is completely cooled, the filament is completely pushed out from the small head end until it can be easily trimmed. If the filament is not smooth enough, you can trim it gently with a knife.
Test the results after the repair is completed(carefully bend the joint - straighten - bend - straighten).
If you hear a crisp sound, we need to weld again.
Unscrew the bolt at one end of the waist groove of the connecting piece, take out the filament, and assemble the filament welder for next use.
