Properly clean the joints to be welded. Preheat solid parts (> 6 mm thick) from 150°C to 250°C. Weld with a very short arc and hold the electrode at 90° to the part to be welded, to avoid any risk of porosity.

Caution! Aluminum electrodes are very sensitive to moisture: keep opened cases in a dry place. If moisture returns, re-dry the electrodes at 100°C/2h.

Why choose this basic electrode?

Vacuum-packed 5 or 6Kg electrode for welding highly stressed steel assemblies (carbon and carbon manganese) (tensile strength up to 510 MPa).

It features excellent mechanical properties, particularly at low temperatures.
