Security measures when 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 the place of welding, it is necessary to apply welding in the environment of inert gases. As some elements of a body are galvanized, it is necessary to take the following security measures:
  • When carrying out the welding works or any other works connected with formation of sparks surely switch-off the rechargeable battery (positive and negative cables) and carefully isolate both plug(s) and (+). When working near the rechargeable battery, it needs to be removed. Without code the radio receiver can be switched on only it by the manufacturer or HUNDRED Mercedes-Benzs;
  • When welding galvanized sheets poisonous oxide of zinc is formed. Therefore it is necessary to monitor good ventilation of a workplace. Increase welding current on 10 (at most 30) percent. Apply electrodes from solid copper with high thermal resistance (above + 400 °C). Clear electrodes more often and process them to diameter of a contact surface in 4 mm. Increase pressure upon an electrode. Increase welding time. Time is chosen truly if welding ends are put without splashes;
  • The conditioner details filled with coolant cannot be welded and soldered both soft, and solid 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.
  • At removal of the battery the memories given from electronic blocks, in particular, a radio receiver code are erased!

    In addition

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

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

    The car bottom sheeting from PHV is removed the rotating steel brush or hot air temperature to + 180 °C by means of the pallet. When heating a covering from PHV up to the temperature over 180 °C there is a chemical reaction and the hydrochloric acid promoting active development of corrosion is formed, besides, noxious to health vapors are formed.
