NOTICE
• The type and quantity of the shielding gas quantity depends on the welding task and the
gas nozzle geometry.
• 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.
NOTICE
• The pressure force of the pressure roller has been factory pre-set. Do not change the
contact pressure by bending leaf spring, but only via the fine adjustment, if required.
• Each time the wire is replaced, make sure that the start of the wire is free of burrs and not
bent.
