Abstract
In some aspects, methods for controlling a plasma arc in a plasma torch of a plasma cutting system in a low operating current mode can include: receiving, by a computing device within the plasma power supply, a command to begin a plasma processing operation; generating a pilot arc command to generate a pilot arc within the plasma torch, the generating of the pilot arc command including directing an electrical signal and a gas flow to the plasma torch, the electrical signal being configured to generate the pilot arc at a current having a first arc amperage magnitude; and generating an operational arc command to facilitate a transition from the pilot arc to an operational plasma arc, the generating of the operational arc command including adjusting the current directed to the plasma torch to be a second arc amperage magnitude that is lower than the first arc amperage magnitude.
