Cu φ0.3 / CU φ0.3 _2

Welded at 6.5V 1.6mS.
When the pulse width was increased from 1.6mS to 1.8mS,the copper wire was melted and buried in the resistance solder.
I used it by cutting it so that it can grip 1 mm of the resistance end,
but it is recommended to make a dedicated electrode
that can firmly grip the resistance electrode part.
