Safety
WARNING!
Danger from incorrect operation and work that is not carried out properly.
This can result in serious personal injury and damage to property.
All the work and functions described in this document must only be carried out by technically trained and qualified personnel.
Read and understand this document in full.
Read and understand all safety rules and user documentation for this equipment and all system components.
WARNING!
Danger from electrical current.
This can result in serious personal injury and damage to property.
Before starting work, switch off all the devices and components involved and disconnect them from the grid.
Secure all devices and components involved so they cannot be switched back on.
WARNING!
Danger from electric current due to defective system components and incorrect operation.
This can result in serious personal injury and damage to property.
All cables, leads, and hosepacks must always be securely connected, undamaged, and correctly insulated.
Only use adequately dimensioned cables, leads, and hosepacks.
WARNING!
Danger from contact with toxic welding fumes.
Serious personal injuries may result.
Always extract welding fumes.
Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventilation flow rate of at least 20 m³ (11.77 cfm) per hour at all times.
In case of doubt, the concentration of noxious substances at the work station should be assessed by a safety engineer.
CAUTION!
Danger due to hot system components and/or equipment.
This can result in 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, wirefeeder drive motor, etc.).
Wear suitable protective equipment if cooling down is not possible (e.g., heat-resistant gloves, safety goggles, etc.).
CAUTION!
Danger from operation without coolant.
This can result in damage to property.
Never commission water-cooled devices without coolant.
During welding, ensure that the coolant is circulating correctly. When using Fronius cooling units, this will be the case if proper return flow of coolant can be seen in the cooling unit’s coolant container.
CAUTION!
Risk of coolant escaping.
Personal injury and damage to property may result.
When disconnecting a water-cooled welding torch from the cooling unit or other system components, always seal the coolant hoses using the plastic seal attached to the torch.

Technical data
General
This product meets the requirements set out in standard IEC 60974-7.
NOTE!
The performance data specifications only apply when using standard wearing parts.
When using gas lenses and shorter gas nozzles, the welding current is reduced.
NOTE!
The welding current specifications apply to gas-cooled torch bodies only from a length of 65 mm (2.56 in.).
When using shorter torch bodies, the welding current is reduced by 30%.
NOTE!
When welding at the power limit of the welding torch, use larger tungsten electrodes and gas nozzle opening diameters to increase the service life of the wearing parts.
Take amperage, AC balance, and AC current offset into account as performance-enhancing factors.
