Shielding gas supply

WARNING

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.

Incorrect handling of shielding gas cylinders!
Incorrect handling of shielding gas cylinders can result in serious and even fatal injury.
• Observe the instructions from the gas manufacturer and in any relevant regulations

concerning the use of compressed air!

• Place shielding gas cylinders in the holders provided for them and secure with fixing

devices.

• Avoid heating the shielding gas cylinder!

CAUTION

Faults in the shielding gas supply.
An unhindered shielding gas supply from the shielding gas cylinder to the welding
torch is a fundamental requirement for optimum welding results. In addition, a blocked
shielding gas supply may result in the welding torch being destroyed.
• Always re-fit the yellow protective cap when not using the shielding gas connection.
• All shielding gas connections must be gas tight.

NOTE

Before connecting the pressure regulator to the gas cylinder, open the cylinder valve
briefly to expel any dirt.
