Shielding gas supply

6.9.1

Connecting the shielding gas supply

NOTE

With compact machines, the shielding gas connection is made on the machine itself;

with decompact machines, on the intermediate tube package of the wire feed (see
"Intermediate tube package connection").

•

Before connecting the pressure reducer to the gas cylinder, open the cylinder valve briefly to blow out
any dirt.

• Place the shielding gas cylinder into the relevant cylinder bracket.
• Secure the shielding gas cylinder using a securing chain.

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.

• Tighten gas hose on pressure reducer to be gas tight.
