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 device and all system components.
WARNING!
Danger from electric 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 the devices and components involved to prevent unintentional restarting.
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 due to contact with toxic welding fume.
This can result in serious personal injury.
Always extract welding fume.
Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of at least 20 m³/h (11.77 cfm) at all times.
If in doubt, a safety engineer should be commissioned to check the pollution level in the workplace.
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 due to operation without coolant.
This can result in damage to property.
Never operate water-cooled devices without coolant.
During welding, ensure that there is a proper coolant flow. When using Fronius cooling units, this is the case if a proper coolant return flow can be seen in the coolant container of the cooling unit.
CAUTION!
Risk of coolant escaping.
This can result in injury and damage to property.
Seal the coolant hoses on water-cooled welding torches with the plastic stoppers fitted to them if the hoses are detached from the cooling unit or other system components.
Danger from welding fumes
WARNING!
Danger from the fumes produced during welding, which contain harmful gases and vapours.
These can cause severe damage to health.
A welding operation is not permitted without an extraction unit that is switched 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.

Fitting the inner liners
Checking the clamping nipple
| * | IMPORTANT! Check the clamping nipple before commissioning and every time the inner liner is changed. |
* Carry out a visual inspection for this purpose:
- Left: Brass clamping nipple with sealing disc. You cannot see through the sealing disc.
- Right: Silver clamping nipple with visible hole.
NOTE!
Incorrect or defective clamping nipple for push applications
Gas loss and poor weld properties will result.
Use brass clamping nipples to minimise gas loss.
Check that the sealing disc is intact.
NOTE!
Incorrect clamping nipple for push-pull applications
Wire winder and increased abrasion in the inner liner when using a clamping nipple with sealing disc.
Use the silver clamping nipple to facilitate wire feeding.

Care and maintenance
General
Regular preventive maintenance of the welding torch is essential if trouble-free operation is to be ensured. The welding torch is subjected to high temperatures and heavy soiling. The welding torch therefore requires more frequent maintenance than other components in the welding system.
CAUTION!
Risk of damage from improper handling of the welding torch.
This can result in severe damage to property.
Do not strike the welding torch on hard objects.
Avoid scoring and scratches on the contact tip.
Do not bend the torch body under any circumstances.
