Abstract

A battery-powered welding machine includes a battery, charging circuitry operatively connected to the battery, and output circuitry operatively connected to the battery to receive electrical energy therefrom to create a welding arc. The output circuitry includes a bleed circuit to selectively discharge residual energy in the output circuitry. An isolation switch is connected between battery and the output circuitry to selectively connect and disconnect the battery from the output circuitry. A control system is operatively connected to the isolation switch to control operations of the isolation switch, and operatively connected to the bleed circuit to control discharging of the residual energy in the output circuitry. The control system is configured to detect a high voltage condition within the output circuitry and, when the high voltage condition is detected, automatically operate the isolation switch to disconnect the battery from the output circuitry, and automatically activate the bleed circuit to discharge the residual energy.
