General Purpose Arc Welding Electrodes 4mm

The Sealey WE2540 features a substantial 4mm diameter electrode in a 2.5kg pack, engineered for heavy-duty welding applications requiring maximum penetration and rapid metal deposition. This largest diameter in the range is specifically designed for thick-section mild steel fabrication, structural steelwork, and industrial maintenance where weld strength and speed are critical factors. Manufactured to BS EN 757 standard, these E6013 electrodes deliver robust, high-integrity welds suitable for demanding structural applications. The 4mm diameter provides exceptional penetration depth and the fastest deposition rate in the range, making it the preferred choice for heavy plant repairs, structural steel fabrication, mining equipment maintenance, and industrial construction projects. Despite the larger diameter, these electrodes maintain all-position welding capability. Compatible with both AC and DC currents, they produce clean weld appearances even at higher amperage settings. The 2.5kg pack provides an economical option for users requiring this heavier electrode diameter for occasional heavy fabrication tasks. Features and Benefits: • 4mm diameter for maximum penetration on thick materials • Fastest deposition rate for improved productivity • 2.5kg pack for heavy-duty occasional use • All-position capability maintained despite larger diameter • Clean weld finish even at higher welding currents Specifications: Brand: Sealey Nett Weight: 2.64kg Pack Weight: 2.5kg Size: Ø4 x 350mm Welding Current: 135-190A
