slbrillreRefuse Filament Waste: If the filament is disconnected during printing, or there is excess material after printing, which is not enough to print a model, it can be connected to continue printing. Multi-color Printing Models: Different colors of the same filament can be connected to print a multi-level model Suitable for: Wide range of applications for most 1.75mm filaments. Filament Welder Connector Material: All-metal 3D printer filament connector using all-metal materials, innovative design, easy to use Note: Prolonged exposure of the wire to air often leads to water loss and embrittlement. To prevent the filament from becoming brittle, seal it Features Product Name: slbrillre filament welder connector Fit for: 1.75mm filament Suitable: PLA ABS filament ect Usage: 3D printer Color: Black Material: Aluminum Package Including 1PC * Filament Connector 1PC * Allen Wrench How to Use 1. Cut off the two filament heads that need to be connected. 2. One end pass from the direction of the big end of the filament welder to the exposed 1-2mm. 3. The other end goes from the direction of the small head to the exposed 1-2mm. 4. Burn in the fire for 5-7 seconds. (This time is mainly for ordinary PLAABS, other harder filaments should be slightly longer) 5.Then quickly push the filament from the small end into the small hole at the large end, slowly (does not have to be fast). 6.Then slowly pull back when the joint is exposed, back and forth several times. 7.After the filament is completely cooled, the filament is completely pushed out of the small head until it can be easily cut. 8.Test the results after the repair is completed (carefully bend the joint - straighten - bend - straighten). 9. (Cette fois est principalement pour le PLAABS ordinaire, les autres filaments plus durs devraient tre lgrement plus longs) 5.Ensuite, poussez rapidement le filament de la petite extrmit dans le petit trou la grande extrmit, lentement (ne doit pas tre rapide). 6.Ensuite, tirez lentement vers l'arrire lorsque le joint est expos, d'avant en arrire plusieurs fois. 7.Une fois que le filament est compltement refroidi, le filament est compltement pouss hors de la petite tte jusqu' ce qu'il puisse tre facilement coup. 8.Testez les rsultats une fois la rparation termine (pliez soigneusement le joint - redressez - pliez - redressez). 9. If you hear a crisp sound, we need to weld again. 10.Unscrew the bolt at one end of the size groove with the connecting piece, remove the filament, and assemble the filament welder for next use. Note 1. The more the filament is used, the more severe the final bending is, and the rebound force is relatively large. Therefore, it is stabilized with a finger before firing, which can increase the success rate. 2. The filament hardness of different materials is different. 3.The harder the material, the longer the burning time. 4.Do not wait until the end of the filament is very close to the extruder. 5.When using, push from the small end to the large end.
