Product information

Description

Metalweld RUTWELD R3 4.0 mm is a rutile-coated manual metal arc (MMA) welding electrode supplied in a 4.5 kg pack. Intended for welding mild steels, this 4.0 mm electrode delivers stable arc performance and predictable bead formation for general fabrication, repair and maintenance tasks. The rutile coating contributes to a smooth arc, relatively low spatter and straightforward slag detachment, making it suitable for workshop and on-site applications where consistent weld appearance and ease of use are required.

Advantages

The rutile flux formulation ensures smooth arc characteristics and easy re-striking, reducing interruptions during welding. The electrode produces a compact, uniform weld bead with moderate penetration suitable for common structural and repair jobs. Slag peels off cleanly after cooling, minimising post-weld cleaning time. The 4.5 kg pack provides an economical quantity for continuous work while the 4.0 mm diameter balances current capacity and accessibility for joints of typical thicknesses.

Suitable for

  • General steel fabrication and structural welding
  • Repair and maintenance of machinery and metal components
  • Welding of mild and low-alloy steels
  • Workshop and field/on-site welding tasks

Key specifications

  • Coating type: rutile
  • Electrode diameter: 4.0 mm
  • Pack weight: 4.5 kg
  • Welding process: Manual Metal Arc (MMA/SMAW)
  • Typical arc characteristics: smooth, low spatter
  • Recommended material: mild steel

How to use

Select appropriate welding current and polarity for a 4.0 mm rutile electrode according to your power source and joint configuration, then strike the arc and maintain a consistent travel speed to achieve uniform bead formation. Allow slag to solidify before chipping or brushing to reveal the weld. Observe standard safety procedures including suitable personal protective equipment, ventilation and electrode storage in dry conditions to prevent moisture absorption that can cause porosity or arc instability.

Usage recommendations

For best results, store electrodes in a dry place and, if necessary, bake according to manufacturer guidelines before use when electrodes have been exposed to humidity. Use this electrode for plates and sections of typical workshop thicknesses where smooth arc behaviour and easy slag removal are priorities. Adjust welding parameters to obtain the desired penetration and bead profile for the specific joint design.
