Danger From Flying Sparks; Risks From Grid Current And Welding Current - Fronius TPS/i Robotics TWIN Push Operating Instructions Manual

Take the following precautionary measures for fumes and harmful gases:
-
-
Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventilation flow
rate of at least 20 m³ per hour.
Use a welding helmet with air supply if there is insufficient ventilation.
If there is uncertainty as to whether the extraction capacity is sufficient, compare the mea-
sured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the welding fumes are:
-
-
-
-
-
Consult the corresponding material safety data sheets and manufacturer's instructions for
the components listed above.
Recommendations for exposure scenarios, risk management measures and identifying
working conditions can be found on the European Welding Association website under
Health & Safety (https://european-welding.org).
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
When no welding is taking place, close the valve of the shielding gas cylinder or the main
gas supply.
Danger from Fly- Flying sparks can cause fires and explosions.
ing Sparks
Never undertake welding near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the arc or pro-
tected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through small cracks
and openings. Take appropriate measures to ensure that there is no risk of injury or fire.
Do not undertake welding in areas at risk of fire and explosion, or on sealed tanks, drums,
or pipes if these have not been prepared in accordance with corresponding national and
international standards.
Do not undertake welding on containers in which gases, fuels, mineral oils, and the like are/
were stored. Residues pose a risk of explosion.
Risks from Grid
An electric shock is life-threatening and may be deadly.
Current and
Do not touch voltage-carrying parts inside or outside of the device.
Welding Current
During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the feed roll-
ers, as well as all pieces of metal that are in contact with the welding wire, are live.
Always place the wirefeeder on a sufficiently insulated base or use a suitable insulating
wirefeeder holder.
