Welding Electrodes GRAPHITE 56H830 rutile low-voltage 2.5 mm 1 kg

GRAPHITE 56H830 welding electrodes are rutile-coated, low-voltage electrodes with a 2.5 mm diameter supplied in a 1 kg pack. Intended for manual metal arc (MMA) welding, these electrodes are formulated to deliver stable arc ignition and a consistent melt for general-purpose steel fabrication and maintenance. The rutile coating supports easy striking and restriking of the arc while promoting smooth bead appearance and straightforward slag removal after welding.

Advantages

These rutile low-voltage electrodes provide stable arc characteristics and predictable deposition suitable for a variety of steel types. The 2.5 mm diameter balances ease of use and deposition rate for typical maintenance and repair tasks. The coating composition promotes smooth bead contours and manageable slag that peels away cleanly, reducing post-weld cleaning time and helping achieve uniform weld appearance.

Suitable for

• General steel fabrication and light construction welding
• Maintenance and repair of machinery, metal structures and equipment
• On-site or workshop MMA welding where low-voltage stability is required
• Welds requiring smooth bead appearance and easy slag removal

Key specifications

• Electrode type: rutile-coated manual metal arc (MMA) electrode
• Diameter: 2.5 mm
• Pack weight: 1 kg
• Intended welding current: low-voltage MMA applications
• Suitable base material: common carbon steels and typical structural steels

How to use

Select an appropriate welding current for 2.5 mm rutile electrodes following the equipment manufacturer’s guidance. Prepare and clean the joint surfaces to remove grease, rust and scale for consistent fusion. Use proper electrode polarity and MMA technique: strike the arc, maintain a stable arc length and travel speed appropriate for the joint geometry. Break and remove slag between passes as needed to ensure proper interpass cleaning and visual inspection of the weld bead.

Usage recommendations

Store electrodes in a dry, temperature-stable environment to prevent moisture pickup and maintain welding performance. If electrodes become damp, follow the manufacturer's drying procedures before use. Always wear appropriate personal protective equipment and follow safety procedures for MMA welding, including ventilation to avoid fume exposure.
