5.4 TIG welding

5.4.1 Shielding gas supply (shielding gas cylinder for welding machine)

WARNING

Risk of injury due to improper handling of shielding gas cylinders!

Improper handling and insufficient securing of shielding gas cylinders

can cause serious injuries!

• Place shielding gas cylinder into the designated holder and secure with

fastening elements (chain/belt)!

• Attach the fastening elements within the upper half of the shielding gas

cylinder!

• The fastening elements must tightly enclose the shielding gas cylinder!

An unhindered shielding gas supply from the shielding gas cylinder to the welding torch is a fun-

damental 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.

Cylinder valve

• Before connecting the pressure regulator to the gas cylinder, open the cylinder valve briefly to blow

out any dirt.

• Tighten the pressure regulator screw connection on the gas bottle valve to be gas-tight.
• Screw the shielding gas hose of the welding torch to the pressure regulator outlet.
