Hybrid And Electric Vehicle Welding Best Practices

When welding on an HEV or EV, follow the same precautions as when welding on a conventional vehicle. In addition, there are precautions to take with the high-voltage battery. As a best practice, disconnect both the 12 V battery and the high-voltage battery service disconnect. (Note: Always disable the high-voltage battery following the vehicle makers repair information and follow all safety precautions.)

Refinish Precautions

"Do not take over 70°C(158°F) / 30 minutes or 80°C(176°F) / 20 minutes when painting because exposing a high-voltage battery to intense heat may cause deterioration."
