S119832-089 - Hobart 18AC 3/32-Inch E7018 Stick Electrode 10lb Pack

Optimized E7018 Performance for AC Power Sources

The Hobart 18AC 3/32" Stick Electrode is a specialized low-hydrogen electrode designed to bridge the gap between industrial performance and utility equipment. Standard E7018 electrodes often struggle to maintain a stable arc on Alternating Current (AC) power sources, particularly those with lower Open Circuit Voltage (OCV). The Hobart 18AC formulation addresses this by incorporating specific arc stabilizers that ensure smooth operation, easy striking, and consistent restriking capabilities without the frustration of arc outages.

This electrode is classified for all-position welding, making it a versatile choice for complex fabrication tasks where out-of-position welds are necessary. While it excels on AC, it is also fully compatible with Direct Current Electrode Negative (DCEN) and Direct Current Electrode Positive (DCEP), providing maximum flexibility across different machine types. It is engineered for joining low, medium, and high-carbon steels, delivering high-quality mechanical properties typical of the E7018 classification.

One of the standout features of the Hobart 18AC is its suitability for skip and tack welds. The easy-start nature of the rod reduces the likelihood of porosity at the start of the weld and minimizes the effort required to initiate the arc repeatedly. This makes it an excellent inventory choice for maintenance, repair, and operations (MRO) environments where quick repairs and tacking are frequent requirements.

Packaged in a convenient 10 lb pack, this product ensures that professionals and serious hobbyists have a sufficient supply of high-quality filler metal that adapts to their power source limitations rather than requiring an equipment upgrade.
