MAG welding
MIG brazing
MIG welding (aluminium)
TIG
Notes on aluminium welding
A two-stage pressure reducer should always be used for aluminium welding.
A venturi for a gas flow of 0 -16 l/min is fitted on each wire feed unit as standard. For applications where a
higher gas flow rate is required (e.g. for aluminium), a venturi of 0 -25 l/min (see accessories) should be
used.
Consequences of incorrect shielding gas settings
• Insufficient shielding gas:
Inadequate gas protection, the indrawn air results in pores in the weld seam.
• Excessive shielding gas:
Turbulence can be caused, allowing air to enter and cause pores in the weld seam.

Recommended shielding gas quantity
Wire diameter x 11.5 = l/min
Wire diameter x 11.5 = l/min
Wire diameter x 13.5 = l/min (100 % argon)
Gas nozzle diameter in mm corresponds to l/min gas throughput
