@-20 °C > 100 J

@-40 °C > 60 J


Maintain a short arc, the electrode almost in vertical position to the work piece.

Avoid porosities by striking the arc on a spare piece of metal. Renew this procedure for each weld. At the end of the bead come back with the arc on the deposit to avoid crater-formation.

Always use very dry electrodes to obtain the highest possible mechanical characteristics.

When necessary preheat and dry the electrodes in the Lastidry for 2 h at 300 °C (570 °F)
