Portable Spot Welder Machine

Q: Can it weld togehther the end of a bike brake cable?

Nothing will weld that successfully. Buy a new cable.

Q: How many welds can this unit make off of the battery on the max power setting?

Perfect weld 120 times. After that it will be less quality

Q: What kind of eye protection is needed when using this spot welder?

Any eye covering will work. I wear glasses so I'm not too concerned . The spot welder doesn't throw any sparks that I can see.
