Welding Electrode ESAB Rutile FI 4.0 x 350 mm – 5.4 kg, approx. 121 pcs

ESAB Rutile FI welding electrodes, 4.0 mm x 350 mm, supplied in a pack of approximately 121 pieces with a total weight of about 5.4 kg. These rutile-coated manual metal arc (MMA) electrodes are designed for general-purpose welding of mild and low-alloy steels. The coating formulation provides easy arc striking, stable arc characteristics and smooth slag detachability, making the electrodes suitable for workshop repairs, fabrication and maintenance tasks where consistent bead appearance and reliable performance are required.

Advantages

Rutile FI electrodes offer reliable arc ignition and a stable welding arc that simplifies operator control. The rutile coating produces a smooth, easily removable slag and a uniform weld bead appearance, reducing post-weld cleaning time. The 4.0 mm diameter provides a balance between deposition rate and accessibility for common joint types, while the 350 mm length allows comfortable handling and minimal electrode changeover during medium-duty welding jobs.

Suitable for

• General workshop repairs on mild steel
• Fabrication and structural welding of low-alloy steels
• Maintenance and onsite repair tasks
• Single-pass and multi-pass fillet and butt welds in standard structural sections

How to use

Select an appropriate welding current and polarity for 4.0 mm rutile electrodes according to your welding power source and the material thickness. Clean the joint area of rust, oil and scale before welding to ensure good fusion. Strike the arc and maintain a consistent travel speed and arc length to achieve a stable bead; rutile coating assists in arc stability and slag formation. After welding, allow the weld to cool and remove the slag to inspect bead quality and carry out any required finishing operations.

Usage recommendations

Use electrode sizes and current settings recommended in the welding equipment documentation for 4.0 mm rutile electrodes. Store electrodes in a dry environment to prevent coating moisture pickup. For critical or high-strength applications, verify material compatibility and mechanical requirements before use and follow applicable welding procedures and safety standards.
