Welding electrode Metalweld BASOWELD non-alloy 2.5 mm, 4.0 kg

Basoweld non-alloy welding electrode by Metalweld, diameter 2.5 mm and weight 4.0 kg per pack, is a basic covered electrode for manual metal arc (MMA) welding of carbon and low-alloy steels. The product is intended as a consumable for portable and workshop welding, offering straightforward performance for general repair, construction and maintenance tasks. The electrode’s flux coating is formulated to support stable arc striking and consistent weld deposition when welding in standard positions on mild and low-alloy steels.

Advantages

The Metalweld BASOWELD non-alloy electrode provides reliable arc stability and moderate weld deposition rate, suitable for routine maintenance and fabrication work. Its basic flux coating reduces spatter and supports slag detachability, helping to produce acceptable bead appearance with minimal cleanup. Packaged as a 4.0 kg bundle, it is convenient for repeated use in both portable and workshop environments and compatible with standard MMA welding equipment calibrated for a 2.5 mm electrode.

Suitable for

• Repair and maintenance of machinery and equipment
• Construction and structural steel assembly
• General fabrication and metalwork in workshops
• On-site welding and portable repair tasks

Key specifications

• Electrode type: non-alloy covered electrode for MMA welding
• Diameter: 2.5 mm
• Pack weight: 4.0 kg
• Intended base materials: carbon steels and low-alloy steels
• Flux coating: basic-type flux formulated for stable arc and slag detachability

How to use

Select welding current and polarity according to standard MMA practice for a 2.5 mm covered electrode and the welded material. Prepare joint surfaces by removing dirt, rust and scale to ensure proper fusion. Strike an arc and maintain a consistent travel speed and electrode angle to achieve uniform penetration and bead profile. After welding, chip and brush the slag away and inspect the weld for continuity and visual defects; perform additional grinding or heat treatment if required by the application.

Usage recommendations

Store electrodes in a dry environment to prevent moisture pickup in the flux coating. If electrodes become damp, follow the manufacturer’s drying instructions before use to avoid porosity and arc instability. Use appropriate personal protective equipment and follow applicable safety standards when performing MMA welding.
