Safety rules General The device is manufactured using state-of-the-art technology and according to recognised safety standards. If used incorrectly or misused, however, it can cause: injury or death to the operator or a third party, damage to the device and other material assets belonging to the operat- ing company, inefficient operation of the device.
Environmental Operation or storage of the device outside the stipulated area will be deemed conditions as not in accordance with the intended purpose. The manufacturer shall not be held liable for any damage arising from such usage. Ambient temperature range: during operation: -10 °C to + 40 °C (14 °F to 104 °F) during transport and storage: -20 °C to +55 °C (-4 °F to 131 °F) Relative humidity:...
Protecting your- Persons involved with welding expose themselves to numerous risks, e.g.: self and others flying sparks and hot pieces of metal arc radiation, which can damage eyes and skin hazardous electromagnetic fields, which can endanger the lives of those using cardiac pacemakers risk of electrocution from mains current and welding current greater noise pollution...
Otherwise, a protective mask with an air supply must be worn. Close the shielding gas cylinder valve or main gas supply if no welding is tak- ing place. If there is any doubt about whether the extraction capacity is sufficient, the measured toxic emission values should be compared with the permissible limit values.
All cables and leads must be secured, undamaged, insulated and adequately dimensioned. Replace loose connections and scorched, damaged or inade- quately dimensioned cables and leads immediately. Use the handle to ensure the power connections are tight before every use. In the case of power cables with a bayonet connector, rotate the power cable around the longitudinal axis by at least 180°...
EMC Device Clas- Devices in emission class A: sifications Are only designed for use in industrial settings Can cause line-bound and radiated interference in other areas Devices in emission class B: Satisfy the emissions criteria for residential and industrial areas. This is also true for residential areas in which the energy is sup- plied from the public low-voltage mains.
Specific hazards Keep hands, hair, clothing and tools away from moving parts. For example: Fans Cogs Rollers Shafts Wirespools and welding wires Do not reach into the rotating cogs of the wire drive or into rotating drive com- ponents. Covers and side panels may only be opened/removed while maintenance or repair work is being carried out.
Page 14
During operation Ensure that all covers are closed and all side panels are fitted properly. Keep all covers and side panels closed. The welding wire emerging from the welding torch poses a high risk of injury (piercing of the hand, injuries to the face and eyes, etc.). Therefore always keep the welding torch away from the body (devices with wire-feed unit) and wear suitable protective goggles.
Factors affecting The following requirements with regard to shielding gas quality must be met if welding results the welding system is to operate in a correct and safe manner: Size of solid matter particles < 40 μm Pressure dew point < -20 °C Max.
Safety measures A device toppling over could easily kill someone. Place the device on a solid, at the installation level surface such that it remains stable location and dur- The maximum permissible tilt angle is 10°. ing transport Special regulations apply in rooms at risk of fire or explosion Observe relevant national and international regulations.
Cooling Liquid FCL 10/20 does not ignite. The ethanol-based coolant can ig- nite under certain conditions. Transport the coolant only in its original, sealed containers and keep well away from any sources of ignition. Used coolant must be disposed of properly in accordance with the relevant na- tional and international regulations.
(e.g. relevant product standards of the EN 60 974 series). Fronius International GmbH hereby declares that the device is compliant with Directive 2014/53/EU. The full text on the EU Declaration of Conformity can be found at the following address: http://www.fronius.com Devices marked with the CSA test mark satisfy the requirements of the rele- vant standards for Canada and the USA.
