Welding Precautions

Take precautions before electrically welding any portion of the unit or the vehicle to which it is attached. Verify that welding currents are not allowed to flow through the unit’s electronic circuits.

Observe the following precautions when welding to avoid damaging electronic components.

• If the microprocessor has a power switch, turn it OFF before connecting or disconnecting the battery.

• Disconnect power to the unit.

• Disconnect all wire harnesses from the microprocessor.

• If there are any electrical circuit breakers in the control box, switch them OFF.

• Close the control box.

• Components that could be damaged by welding sparks should be removed from the unit.

• Use normal welding procedures, but keep the ground return electrode as close to the area being welded as practical. This will reduce the likelihood of stray welding currents passing through any electronic circuits.
