Safety measures
in normal opera-
tion
If the shielding gas cylinder is not connected, leave the valve cap in place on
the cylinder.
The manufacturer's instructions must be observed as well as applicable na-
tional and international regulations for shielding gas cylinders and accesso-
ries.
Risk of suffocation from the uncontrolled escape of shielding gas
Shielding gas is colourless and odourless and, in the event of a leak, can dis-
place the oxygen in the ambient air.
- Ensure an adequate supply of fresh air with a ventilation rate of at least
20 m³/hour.
- Observe safety and maintenance instructions on the shielding gas cylin-
der or the main gas supply.
- Close the shielding gas cylinder valve or main gas supply if no welding is
taking place.
- Check the shielding gas cylinder or main gas supply for uncontrolled gas
leakage before every start-up.
A toppling device can cause life-threatening injuries. Place the device on a sol-
id, level surface so that it remains stable
- The maximum permissible tilt angle is 10°.
Do not operate or store the device in a potentially explosive atmosphere.
Special regulations apply in rooms at risk of fire or explosion.
Observe relevant national and international regulations.
Use internal directives and checks to ensure that the workplace environment
is always clean and clearly laid out.
Only set up and operate the device in accordance with the degree of protec-
tion shown on the rating plate.
When setting up the device, ensure there is an all-round clearance of 0.5 m (1
ft. 7.69 in.) to ensure that cooling air can flow in and out freely.
When transporting the device, observe the relevant national and local guide-
lines and accident prevention regulations. This applies especially to guidelines
regarding the risks arising during transport.
After transporting the device, it must be visually inspected for damage before
commissioning. Any damage must be repaired by trained service technicians
before commissioning the device.
Odourless and colourless shielding gas may escape unnoticed if an adapter
is used for the shielding gas connection. Prior to assembly, seal the device-
side thread of the adapter for the shielding gas connection using suitable Tef-
lon tape.
Only operate the device if all safety devices are fully functional. If the safety
devices are not fully functional, there is a risk of
- injury or death to the operator or a third party,
- damage to the device and other material assets belonging to the operator,
- inefficient operation of the device.
Any safety devices that are not functioning properly must be repaired before
switching on the device.
