Castolin DRUT RDZENIOWY ALU FLAM 198 FCW 2M×2MM flux-cored aluminum welding wire

Castolin DRUT RDZENIOWY ALU FLAM 198 FCW 2M×2MM flux-cored aluminum welding wire is a gasless, internally fluxed filler designed for welding aluminum components where external shielding gas is not practical. The wire has a 2 mm diameter and a 2 m length, and its flux core supplies deoxidizers and slag-forming agents that promote consistent wetting and reduced porosity on aluminum alloys. It is suitable for repair, maintenance and light fabrication tasks that require corrosion-resistant aluminum welds without the need for external gas cylinders.

Advantages

This flux-cored aluminum welding wire provides stable arc characteristics and localized cleaning action from the internal flux, improving weld quality on oxidized or mildly contaminated surfaces. The gasless design removes the dependency on shielding gas, simplifying setup and making the wire suitable for outdoor or draft-prone environments. With a compact 2 m length and a 2 mm diameter, the product is convenient for on-site repairs and maintenance where mobility and quick replacement are important.

Suitable for

• On-site aluminum repairs and maintenance
• Joining thin to moderate-thickness aluminum components
• Welding in outdoor or drafty conditions without external shielding gas
• Light fabrication and assembly of aluminum parts

Key specifications

• Wire type: flux-cored aluminum welding wire (gasless)
• Diameter: 2 mm
• Length: 2 m
• Core: internally fluxed for cleaning and slag formation
• Application: manual gasless welding of aluminum alloys

How to use

Prepare the aluminum surfaces by removing loose oxides, heavy contaminants and coatings in the weld area; light oxidation can be addressed by the internal flux but cleaner surfaces produce more consistent results. Use appropriate polarity and welding parameters recommended for flux-cored aluminum wire with your welding equipment; set current and travel speed to achieve a stable arc and proper penetration for the material thickness. Maintain consistent wire feed and keep the nozzle/arc area clear of excessive slag buildup between passes.

Usage recommendations

For best results, use this flux-cored wire on clean-fit joints with proper joint preparation. When welding outdoors, protect the weld area from strong wind if possible, and inspect finished welds for slag inclusions or porosity. Follow personal protective equipment guidelines for aluminum welding, including appropriate eye, skin and respiratory protection.
