A sharpened 1mm tungsten electrode was used to attach the straight pin to these piano wires. The Orion Pulse 150i was set to Nano Mode at 4ws energy and the sloped agitation feature was enabled for better penetration and smoothing. We ground the end of the piano wire flat before attempting the weld (the smaller the gaps between the surfaces being welded the better).
It can be helpful to ball the end of the piano wire prior to attaching it to the straight pin. The size of the ball can be controlled by increasing or decreasing the energy. The ball formed in the video was made using 20ws energy in Micro Mode with sloped agitation. After the wire has been balled you can grind a flat on the ball for a closer fit. The extra material from the ball helps prevent necking at the weld joint.
