OVERVIEW

High-Performance E7018 Electrodes for AC Power Sources

The Hobart 18AC 3/32-inch Stick Electrode is a specialized welding consumable designed to bridge the gap between professional-grade low hydrogen requirements and the limitations of standard AC utility welders. While traditional E7018 electrodes often require DC power for optimal stability, the Hobart 18AC is chemically formulated with arc stabilizers that allow it to run smoothly on Alternating Current (AC). This makes it an indispensable asset for fabrication shops and maintenance crews that rely on AC-only power sources but still demand the mechanical properties and crack resistance of a low-hydrogen weld deposit.

Meeting the AWS E7018 H8 specification, this electrode delivers high-quality welds on low, medium, and high-carbon steels. It is engineered to operate effectively even on machines with low Open Circuit Voltage (OCV), preventing the frustration of rod sticking and arc outages common with standard electrodes. The 3/32-inch diameter is versatile enough for thin-to-medium gauge materials, providing excellent control in all welding positions, including flat, horizontal, vertical-up, and overhead. This all-position capability ensures that complex fabrication tasks can be completed without the need to reposition heavy workpieces.

For industrial applications requiring skip or tack welds, the Hobart 18AC excels with its superior restrike capability. The slag system is designed to be easily removable, reducing post-weld cleanup time and increasing overall productivity. Whether used for general fabrication, structural repairs, or maintenance operations, this 5lb plastic pack ensures you have a reliable, moisture-resistant supply of electrodes ready for immediate use. Trust Josef Gas to supply high-quality Hobart consumables that enhance the capabilities of your existing welding equipment.
