Security measures at carrying out body works

At repair of a body it is necessary to apply spot welding. Only if it is impossible to bring electrodes to a place of welding, it is necessary to apply welding in the environment of inert gases. As some elements of a body are zinced, it is necessary to accept the following security measures:

- At carrying out welding works or any other works connected with formation of sparks, surely disconnect the storage battery (positive and negative cables) and carefully isolate both plugs (-) and (+). At works near the storage battery, it is necessary for removing.

 Attention! At removal of the battery the memories given from electronic blocks, in particular, a radio receiver code are erased. Without a code the radio receiver can be included only by his manufacturer or HUNDRED DAIMLER-BENZ. Familiarize with remarks in the Section Check of system of a charging.


When welding the zinced sheets poisonous oxide of zinc is formed. Therefore it is necessary to watch good ventilation of a workplace.

Increase a welding current by 10, at most 30 %.


Apply electrodes from firm copper with high thermal firmness (above + 400°С).

Clear electrodes more often and process them till diameter of a contact surface of 4 mm.

Increase pressure upon an electrode.

Increase welding time. Time is chosen truly if welding points are put without splashes.

The details of the conditioner filled with a coolant, it is impossible to weld and solder both soft, and firm solder. It belongs also to a situation when there is a danger of heating of elements of the conditioner during the welding or the soldering of other elements of a design.

In addition

It is not necessary to open a contour of cooling of the conditioner since the coolant at hit on skin can cause frostbite.

When drawing a paint and varnish covering in the drying furnace heating of the car to temperature above + 80°С is not allowed. Otherwise electronic devices of the car can be damaged. Besides, in the conditioner the pressure raises, able to lead to system destruction.

- The sheeting of the bottom of the car from PHV is removed a rotating steel brush or hot air in temperature to + 180°С by means of a shpatel. Owing to covering heating from PHV to temperature over 180 ° With there is a chemical reaction and the hydrochloric acid promoting active corrosion, besides, is formed unhealthy pairs are formed.
