Product description
All-positional NiMo low alloy steel MMA electrode
MMA electrode with a basic flux coating on high purity mild steel core wire. Moisture resistant coating provides
very low weld metal hydrogen levels.
Recovery is about 120% with respect to core wire, 65% with respect to whole electrode.

Storage
3 hermetically sealed ring-pull metal tins per carton, with unlimited shelf life. Direct use from tin will give
hydrogen < 5ml/100g for longer than a working shift of 8h.
For electrodes that have been exposed:
Redry 250 – 300°C/1-2h to ensure H2 < 10ml/100g, 300 – 350°C/1-2h to ensure H2 < 5ml/100g. Maximum
420°C, 3 cycles, 10h total.
Storage of redried electrodes at 50 – 150°C in holding oven or heated quiver: no limit, but maximum 6 weeks
recommended. Recommended ambient storage conditions for opened tins (using plastic lid): < 60% RH, > 18°C.

* Minimum as-welded values are for AWS ER80S-D2. As shown MAG welds using more oxidising shielding gas
(higher CO2 + O2) have lower strength. The AWS classification for ER80S-D2 is based on 100%CO2 which is
seldom used; alternatively this wire can also be classified as ER90S-D2 using low CO2 gas mixtures.
