Improper handling and insufficient securing of shielding gas cylinders can cause
serious injuries!
• Observe the instructions from the gas manufacturer and any relevant regulations
concerning the use of compressed air!
• Do not attach any element to the shielding gas cylinder valve!
• Prevent the shielding gas cylinder from heating up.
Risk of accident by exceeding the maximum size of the gas cylinder!
Maximum permissible shielding gas cylinder size at fill pressure. Exceeding these limits
can cause the loss of steadiness up to an angle of 10° (IEC 60974-2). This can cause
injuries.
• max. 20 litres geometric volume at 200 bar fill pressure.
