Recommendations

Clean the welding area. If thickness exceeds 6 mm, preheat to 150°C–250°C.

Attention! To avoid porosity, weld with a short arc and keep the electrode at 90°. Weld quickly.

Attention! Aluminium electrodes are very sensitive to moisture. Store opened packages in a dry place. Dry if necessary 3h at 100°C.
