AH00.00-N-0005-01A Measures For Preventing Damage To Vehicles Or Components When Performing Arc Welding Work

The following measures must be taken before welding in order to prevent damage to various vehicle components:

1. Have fire extinguishers at the ready.
2. The negative terminal of the battery must be disconnected and covered up.
3. In vehicle with airbags the red, 12-pin test connection/plug-in connection must be disconnected no sooner than two seconds after the battery has been disconnected (risk of unwanted activation).
6. Attach protective shields to prevent flying sparks and radiated heat in endangered areas.
7. Do not touch electronics housings or electrical cables with the welding electrode or the welder's ground connection.
8. If two parts are being welded together, both parts must be attached to the welder's negative clamp.
9. Make direct connection between the electrical welder's ground connection and the part being welded. Ensure that there are no electrically insulating parts between the ground connection and the welding point.
10. Protect or remove any parts that are sensitive to heat such as plastic cables.
11. Remove electrical cables that are laid in cavities and/or pipelines, covered containers and electrical components from the danger area before welding.
12. If possible, the points where the welded part is being attached to the vehicle and the ground terminal is attached to the electrical welder must be bare; remove all traces of paint, corrosion, oil, grease and soiling.
13. The ground terminal of the welder must not be attached to the transmission. The welding current can cause arcing at the bearing points inside the transmission. The structural changes that this causes lead to premature failure of the equipment.
