filament welder inspired by https://www.youtube.com/watch?v=gyMvT61mYPY it is better to use a jig :) to place the ends together isn't as easy as shown in the video adjust the ends.. use a small flame..heat shortly, press slightly together, and push the joint point into the PTFE tube (cool down before pulling out) when using too much pressure and heat one can extrude the filament and pulling it out too soon will stretch the joint
