WARNING!
Danger due to hot system components and/or equipment.
Can result in serious burns or scalding.
▶
Before starting work, allow all hot system components and/or equipment to
cool to +25°C/+77°F (e.g., coolant, water-cooled system components, wire-
feeder drive motor, etc.)
▶
Wear suitable protective equipment (e.g., heat-resistant gloves, safety gog-
gles, etc.) if cooling down is not possible.
WARNING!
Danger from contact with toxic welding fumes.
This can result in serious personal injuries.
▶
Welding is not permitted without an extraction unit being switched on.
▶
It may not be sufficient to only use a fume extraction torch to reduce the
concentration of noxious substances at the work station. In this case, install
an additional extraction system to properly reduce the concentration of
noxious substances at the work station.
▶
If in doubt, the concentration of noxious substances at the work station
should be assessed by a safety engineer.
CAUTION!
Danger from operation without coolant.
This can result in damage to property.
▶
Never operate water-cooled welding torches without coolant.
▶
During welding, ensure that the coolant is circulating correctly – this will be
the case for Fronius cooling units if a regular return flow of coolant can be
seen in the coolant container of the cooling unit.
▶
The manufacturer will not be liable for any damages due to non-observance
of the above mentioned points. All claims against the warranty are void.
