COATED ELECTRODES

Re-dried basic electrodes can be stored in a heated cabinet at 80 °C without further moisture pick-up. Stainless steel electrodes which have been stored outside of their electrode

box and have become damaged by moisture pick-up can be redried at a temperature of 300–350 °C for 1–2 hours. Redrying should be restricted to a maximum of 3 cycles.

Welding electrodes should be stored in their original package. Preferably in a de-humidified area or in a heating cabinet.

Heating Cabinet at 80 °C

3.01

All basic electrodes and stainless steel electrodes should be re-dried before use. Always do when there is application requirements.

Minidryer 300–350 °C

Unused electrodes should be re-dried before being returned to the heating cabinet.

Rutile electrodes normally no need for re-drying.

Observe recommended

re-drying temperatures and holding times for Unitor electrodes stated on box label Max exposure time for electrodes in the open is 8 hours.
