Welding Electrodes Silver ELEKTRODA 4.0x400 mm, 5 kg (model 10829)

Silver ELEKTRODA welding electrodes 4.0x400 mm (5 kg pack) are shielded stick electrodes for manual metal arc (MMA) welding. With a 4.0 mm core diameter and 400 mm length, these electrodes are intended for general-purpose welding of carbon and low-alloy steels. Packaged in a 5 kg container, the electrodes are suitable for maintenance, repair and construction site tasks where reliable stick welding performance is required.

Advantages

These shielded electrodes provide consistent arc stability and good wetting of the weld pool, which simplifies bead formation and reduces spatter. The 4.0 mm diameter balances penetration and ease of handling, allowing effective welding on medium-thickness steel. The flux coating ensures adequate slag formation for protection and easy slag removal after cooling.

Suitable for

• General steel fabrication and structural welding
• Maintenance and repair work on machinery and metal structures
• On-site construction and installation where portable MMA welding is used
• Joining and rebuilding worn or corroded steel parts

Key specifications

• Electrode core diameter: 4.0 mm
• Electrode length: 400 mm
• Pack weight: 5 kg
• Welding process: manual metal arc (MMA / stick welding)
• Intended material: carbon and low-alloy steels
• Flux-coated (shielded) electrode for slag protection

How to use

Prepare the joint by cleaning surfaces from loose rust, paint and oil to ensure good arc initiation and weld quality. Select an appropriate welding current for a 4.0 mm electrode according to your welding machine settings and electrode manufacturer guidance. Strike the arc, maintain a steady travel speed and correct electrode angle to achieve uniform penetration and bead profile. Allow the weld to cool, then chip off the slag and inspect the weld for continuity and defects before any post-weld treatment.

Usage recommendations

Store electrodes in a dry environment to prevent moisture pickup in the flux coating; if electrodes show signs of dampness, follow recommended drying procedures before use. Use appropriate personal protective equipment, including welding helmet, gloves and protective clothing, and ensure adequate ventilation when welding indoors.
