Weld-seam porosity
Torch blow-out unit not connected and/or not sealed
Connect hose and/or seal hose end by means of supplied plug
Spatter accumulating in the gas nozzle, causing inadequate gas-shiel-
ding of the weld-seam
Remove the welding spatter
Either the shielding-gas hose has holes in it, or it is not connected up
properly
Change the shielding gas-hose
The O-ring seals on the connection points are cut or defective
Change the O-ring seals
Moisture / condensate in the shielding-gas hose
Dry the shielding-gas hose
Shielding-gas flow is either too high or too low
Correct the shielding-gas flow
Insufficient shielding-gas flow at the beginning or end of welding
Increase the gas pre-flow or post-flow
The welding wire is rusty or of poor quality
Use only high-quality wires that are free of contaminants
Applies to gas-cooled welding torches: Shielding-gas leakage from
non-insulated inner liners
On gas-cooled welding torches, use only insulated inner liners.
