A portable plasma arc torch system can be used for processing materials. The system includes a replaceable or rechargeable power source and replaceable or rechargeable gas source. A controller communicates with at least one of the power source or the gas source. A plasma delivery device received via the controller current from the power source and gas from the gas source to generate a plasma arc at an output of the plasma delivery device. The plasma arc can be used to process materials such as metallic workpieces. The plasma arc torch can include a wearable portable assembly which includes the replaceable or rechargeable power and gas source. A plasma delivery device receives current from the power source in the assembly and gas from the gas source in the assembly to generate a plasma arc.
