  • AC vs. DC - Welding Productivity

    DC stick welding offers advantages over AC when welding steel, including smoother and more stable arcs, easier starts, fewer arc outages, less spatter and easier vertical up and overhead welding. DC positive polarity provides a high level of penetration into the steel. DC negative polarity results in less penetration but a higher deposition rate.
