WARNING!
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!
Always extract welding fumes.
Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate
of at least 20 m³ (169070.1 US gi) per hour at all times.
If in doubt, a safety engineer should be commissioned to check the pollution
level in the workplace.
CAUTION!
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.
WARNING!
A welding operation is not permitted without an extraction unit that is swit-
ched on.
Under certain circumstances, the sole use of a fume extraction torch is not
sufficient.
In this case, install an additional extractor to reduce the pollution level in the
workplace.
If in doubt, a safety engineer should be commissioned to check the pollution
level in the workplace.
