Select 70C-7

Carbon Steel / Metal Cored / Gas Shielded


Features

  • Formulated to produce substantially less spatter and lower fume generation rates than conventional E70C-6M electrodes.
  • Intended for single and multiple pass welding of carbon and certain low alloy steels, with a minimum tensile strength of 70,000 psi.
  • Exceptionally smooth arc and low spatter level to minimize post weld cleanup, making it ideal for weldments that are to be painted.
  • Offers increased productivity, better fusion on scaled plate material, and more porosity-free weldments as compared to ER70S-3 and ER70S-6 electrodes.
  • Smaller diameter electrodes can be used in all position welding with either pulse arc or short circuit arc welding process.
  • Typical applications include car & truck frames, structural steels, trailers and earthmoving equipment.
