1. A system for depositing a metal material of an electrode on a metal surface of a workpiece, the system comprising:
a tool unit configured to support the electrode, the tool unit including:
a tool housing;
an electrode supporting element configured to support the electrode on the tool housing; and
movement structure configured to move the electrode with respect to the housing via the electrode supporting element;
electrical circuitry configured to produce a voltage potential between the electrode and the metal surface, the electrical circuitry including:
a power source configured to provide power to elements of the electrical circuitry;
a bank of capacitors configured to be selectively charged by the power source and discharged via an electrode engaged by the electrode supporting element to the metal surface;
wherein the power source comprises a rechargeable battery; and
wherein the electrical circuitry additionally comprises a processor configured to control a frequency of arc discharges of electrical power between the electrode and the workpiece as a function of a level of electrical power supplied to the electrode from the bank of capacitors.
