Without the diode, the coil will generate thousands of volts with (obviously) enough current to kill you! (Normally, the low voltage along with your body's high resistance keeps you safe while allowing you to get 90A through the nearly zero-resistance of the weld. When the circuit is broken (a normal part of arc welding). If you add a choke, add a reversed diode (rated for 90A or more) across the choke to kill the Back-EMF. They also hacked up a microwave transformer and used 2nd coil to wrap their own cable to use as a choke. A larger capacitor will send-out larger pieces.)

That could put AC on the capacitor and blow it, or other things could burn-up.
