System for material deposition on a surface

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;
• wherein the rechargeable battery is permanently mounted on one said housing, the rechargeable battery being mounted on an element of the system;
• and
• a base unit separate of the tool unit and having a base housing, the rechargeable battery being permanently mounted on the base housing.
