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 device toppling over could easily kill someone. Place the device on a solid,
level surface such that it remains stable
- The maximum permissible tilt angle is 10°.
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.
Do not lift or transport operational devices. Switch off devices before transport
or lifting.
Before transporting the device, allow coolant to drain completely and detach
the following components:
- Wirefeeder
- Wirespool
- Shielding gas cylinder
After transporting the device, the device must be visually inspected for dam-
age before commissioning. Any damage must be repaired by trained service
technicians before commissioning the device.
Only operate the device when all safety devices are fully functional. If the safe-
ty 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.
Never bypass or disable safety devices.
Before switching on the device, ensure that no one is likely to be endangered.
Check the device at least once a week for obvious damage and proper func-
tioning of safety devices.
