Power up your Lincoln SA-200 and SA-250 welders with our 1-Wire Alternator, the ultimate upgrade for simplicity and efficiency. This 63-amp powerhouse charges by RPM speed, streamlining your setup by only requiring one wire from the alternator battery post to the starter solenoid. Forget the clutter and complexity of multiple wires. Our 1-Wire Alternator with a 1/2" pulley is designed for easy installation and reliable performance, ensuring your welder is always ready with the power it needs, when it needs it. Simplify your power source, boost your welder's efficiency.

It comes with a 1/2" wide crank pulley, but if you have an older Lincoln SA-200 with a F162 motor, you will need to replace that 1/2" pulley with a 5/8" pulley to match the size of your machine's crank pulley. The 1/2" to 5/8" pulley can be found here.

Also comes with 1 split lock washer, 1 flat washer, and 1 hex bolt.
