Forney 42466 Mild Steel Low-Hydrogen Welding Electrode, 5/32", 40 Lb, 100-140AForney E7018 mild steel "Low Hydrogen" welding electrodes easily produces quality results on smaller amperage DC or higher amperage AC welders. It is suitable for all positions on hardenable steels where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional rod. The low hydrogen content reduces cracking and peeling of the weld material. Use for field erections, steel structures, frames,
