Special regulations apply here! - No welding work may be carried out on containers in which gases, fuel, oils, dyes or the like have been stored, even if they have been emptied for a long time.
- Page 29 Welding WARNING! Danger due to burns! Moving parts or thermal parts can damage your body or other people. - Workpieces become very hot during welding, wear suitable protective clothing. - Make sure that the wire, the electrode, the electrode coil, the welding head, the nozzle and the semi-automatic wel- ding gun are heated by the current and become very hot! ATTENTION! MAGNETIC FIELD!
- Page 30 Welding DANGER! ELECTRICAL VOLTAGE! - Never touch any live parts! - There is a danger of an electric shock! - Always wear dry and closed gloves and flame-retardant clothing with insulating properties. - Make sure that the insulation of the workplace is such that no person can be physically damaged by contact with the workplace.
