Fleetweld 35 E6011 AC, DC+, DC- Operators consistently give
this electrode high marks. This quality Lincoln product is a proven
performer for AC pipe welding applications and sheet metal welding.
Fleetweld 35 is a great electrode to use on jobs where the steel isn’t
clean.
Fleetweld 180 E6011 AC, DC+, DC- Got a small AC welder? Here's
your electrode! Fleetweld 180 offers excellent arc stability for
excellent performance with power sources as low as 50V open-circuit
voltage (OCV). A great stick electrode with the ability to start
easily on low open circuit voltage welders.
