Features

Sureweld 70LH (E7018) is a newly developed low hydrogen, moisture resistant iron
powder electrode. The newest addition to the Sureweld line, this electrode has a very
stable arc, excellent slag removal and desirable bead profile.
The basic flux coating on Sureweld 70LH permits joining ‘hard to weld’ steels, including some free machining grades. The tight arc gives good penetration and makes clean up easy.
