NOTE
• The type and quantity of the gases to be used depends on the welding
task. Only pure inert gases or their mixtures may be used as the plasma
gas.
Tab. 4 Process gases according to DIN EN 439 on page EN-4
• To prevent the shielding gas supply from becoming clogged by
impurities, the cylinder valve must be opened briefly, before connecting
the cylinder. This will blow out any impurities that may be present.
• Make all shielding gas connections gas-tight.
• Small amounts of condensation can form in the shielding- and plasma-
gas hoses after long periods of no use and also due to high temperature
fluctuations. Dismount the wearing parts and remove the residues by
actuating the gas test trigger until the shielding and plasma gases are
dry. Perform this procedure every day prior to starting work.

DANGER
Shortness of breath and poisoning caused by inhaling
phosgene gas
During the welding of work-pieces that have been degreased with chlorine-
containing solvents phosgene gas is formed.
• Do not inhale fumes and vapours.
• Ensure sufficient supply of fresh air.
• Rinse work-pieces with clear water prior to welding.
• Do not place degreasing baths containing chlorine in the vicinity of the
welding area.
