Steel Welding Electrode / Graphite Electrode
Steel Welding Electrode / Graphite Electrode is a kind of carbon steel electrode. The solder is a low-hydrogen iron powder type electrode that produces high quality X-ray welds. The steel welding electrode can be used in all positions on AC or DC reverse polarity welding current. E7018 is recommended for welding medium grade carbon steels where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional electrodes.
WELDING CURRENT: AC-DCEP(Electrode Positive)
