WARNING!
When disconnecting a welding torch from the cooling unit or other system
components, always seal the coolant hoses using the plastic seal attached to
the torch.
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.
