What ignition source can be used for oxy-arc cutting?

Explanation:
In oxy-arc cutting, you need to establish an electric arc between a carbon electrode and the workpiece to heat the metal before cutting with the oxygen jet. That initial arc must be struck with an ignition source. A 12-volt battery provides a portable, reliable spark to start the arc, making it the best ignition source for beginning the process. An AC power outlet isn’t used to ignite the arc, a gas torch introduces a flame that isn’t part of this arc initiation, and saying none is needed would ignore the need to start the arc itself.
