The Forney 30685 7018AC welding rod is a low-hydrogen mild steel electrode designed for both AC and DC welding applications on smaller amperage machines. This general-purpose rod delivers reliable results for chassis, frames, trailer hitches, and structural work where consistent quality welds are essential.
The 7018AC rod excels on hardened steels requiring no preheat and on cold-rolled steels that typically exhibit excessive porosity with conventional electrodes. Its low-hydrogen chemistry significantly reduces cracking and peeling of the weld material, while its excellent restart capability makes it an efficient choice for welders of varying skill levels. The rod works across all welding positions and is engineered for low, medium, and high-carbon steels as well as higher-strength low-alloy steels.
Features and Benefits
- Low-Hydrogen Formula: Reduces cracking and peeling, producing stronger, more reliable welds on challenging steel types.
