Coated electrode for repairing cast aluminium and joining aluminium sheets.
Good bond on the base metal.
Porosity free deposit.
Repair of motor blocks, pump housing, pulleys, gear boxes.
Construction of silos, tanks and other constructions.
Repair of casting defects.
Hardness: 50 - 60 HB
Keep the electrode perpendicular to the work piece.
Weld with a short arc to avoid overheating (and possible burn through) and keep the amperage as low as possible. If necessary lower the amperage during welding.
Thick pieces: preheat to 150-200 °C (300-400 °F).
The diameter of the electrodes is more or less equal to the wall thickness of the piece.
The flux-residues should be thoroughly removed with warm water and soap, to avoid corrosion.
The electrodes should be kept dry or they can be dried before welding at a temperature of 150 °C (300 °F).
