ETCPH56S is a E7016-1 H4 Low Hydrogen Arc Welding Electrode. Excellent for structural steel welding where extra low levels of hydrogen are permitted. Also welds C-Mn and low-alloy steels
E7018-1-H4 Low Hydrogen or Basic Electrodes - ETC Brand - Popular Phillips Recipe Welding Rods!
Proline Industrial offers a wide range of low hydrogen electrodes. Low hydrogen arc electrodes are used for welding heavy workpieces and high tensile steels where the weld cracking from heat stress or impurities might be a problem. They are also used for welding low-alloy steel, or steel where the carbon and sulphur contents are higher than in mild steel.
