4Viper2500s1.1 Fire and ExplosionsPay attention to fire and safety regulations in forceat the welding site.• Remove all flammable or combustible materials fromthe welding area and the immediate vicinity.• Suitable fire fighting equipment must always be pre-sent where welding is carried out.• Be aware that a fire risk is present for a considerabletime after welding operations have ceased becauseof sparks and hot slag etc. Take suitable precautionswhen you have finished welding.• Take care when welding containers that have heldflammable or combustible material, these should havebeen specially cleaned before being made availableto the welder. If in doubt do not proceed.1.2 BurnsBe aware that burns may be the result of the heat involvedin the welding process, welding spatter or the Ultra VioletRadiation given off by the arc itself.• Wear suitable flame retardant clothing over all yourbody.• Wear protective gauntlets designed for welding use.• Wear a welding facemask fitted with the correct filtershade suitable for the current at which you will bewelding.• Avoid wearing oily or greasy clothing as a spark mayignite them. Where possible ensure that a suitable firstaid kit and a first aid person qualified in the treatmentof burns are available nearby.1.3 FumesWelding operations give off harmful fumes that are haz-ardous to your health.• Make sure the welding area is well ventilated. Use suit-able fume extractors or exhaust fans if necessary.• If the ventilation is not suitable then breathing appara-tus may have to be used.• Do not weld plated metals or metals which containLead, cadmium, Zinc, Mercury or Beryllium unless youare wearing breathing apparatus approved for thepurpose.1.4 Electric ShockNote! Electric shocks can be Fatal• Do not touch live electrical parts.• Do not work in wet or excessively humid areas and donot site the Viper 2500s on a wet surface.• Avoid touching the work piece whilst welding.• Do not use the Viper 2500s without it’s protective cover• Keep your clothing and body dry1.5 The safe handling of gas cylindersThe Viper 2500s uses argon gas during TIG welding. This isan inert gases and can displace oxygen in the atmosphereleading to asphyxiation.• Note! Gas cylinders are under pressure and can explodeif punctured. Please ensure the cylinder is secured in astable location away from any heat source or potentialmechanical damage.• Check the gas cylinder, pressure regulator and gas hosesregularly for leaks and discard any suspect item.• Do not try to directly connect a gas cylinder to the Viper2500s without using a pressure-reducing regulator de-signed for use with argon.• Do not use gas cylinders whose contents you are unsureof.• The cylinder must be securely fastened to a wall orplaced in a specially designed cylinder carrier.• Always turn off the valve on the gas cylinder when youhave finished welding.• Always install and use pressure regulators in accordancewith the manufacturers instructions.• It is advisable, when attaching the regulator to the gasbottle, to briefly turn on the bottle valve to expel anyforeign objects that may be present. These may laterblock the solenoid valve of the machine if not dealt with.Turn your face away from the bottle valve when under-taking this action.Further information is available in publication HSG118'The safe use of compressed gases in welding, flamecutting and allied processes', which may be obtainedfrom the Health & Safety Executive.1.6 Welding and earth return cables• Earth return and electrode holder cables must have across sectional area of at least 35mm2.• Only use copper cables, the use of Aluminium cablesmay have a detrimental effect on the performance ofthe machine.• Regularly inspect welding cables and connectors forwear abrasion and corrosion. Corroded cables and con-nectors may overheat and become a fire hazard.• Ensure that all welding connectors are fully mated, theconnectors should be pushed fully home and then turnedclockwise to lock. If the connectors are not mated fullythey may overheat and become a fire hazard.• If possible, fasten the earth return clamp directly to thejob to be welded and ensure that the surface is free fromrust and paint.SECTION 1 — SAFETY
