Protecting Protective clothing refers to a variety of different items. Operators should yourself and others protect eyes and face from UV rays, heat and sparks with regulation (continued) protective visor with filter. wear regulation protective goggles with side protection behind the safety visor.
Page 9
Danger from Flying sparks may cause fires or explosions. flying sparks Never weld close to flammable materials. Flammable materials must be at least 11 metres (35 ft) away from the welding process, or alternatively covered with a checked cover. A suitable, tested fire extinguisher must be available and ready for use. Sparks and pieces of hot metal may also get into adjacent areas through small gaps or openings.
Page 10
Risks from mains current and Before working on the device, switch it off and disconnect it from the mains welding current supply. (continued) Attach a clearly legible and easy-to-understand warning sign to the device to prevent anyone from reconnecting it to the mains and switching it on again. After opening the device: discharge all components that are electrically charged ensure that all components in the device are de-energised.

Specific hazar- Never touch the workpiece, electrodes or process tape during or after wel- dous areas ding - risk of burns. (continued) Welding residues can jump off cooling work pieces. The specified protective equipment must therefore also be worn when reworking workpieces, and steps must be taken to ensure that other people are also adequately pro- tected.
