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 on page EN-4
• Make all shielding gas connections gas-tight.
• Small amounts of condensation may form in the shielding and plasma
gas hoses after long periods of no use and also due to high temperature
fluctuations. Dismount the wear 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.
DANGER
Risk of burns
During welding sparks, glowing work-pieces or hot slag can produce
flames.
• Check work area for fire.
• Make suitable fire extinguishing materials available at the workplace.
• Allow work-pieces to cool down after welding.
• Prior to performing welding work, fasten the ground clamp properly to
the work-piece or the welding table.
