Characteristics:

Raajmelt-SPL is an agglomerated aluminates basic type submerged arc welding flux suitable for very high current carrying capacity on both AC and DC. Designed for single, double, and multi-wire systems, it provides excellent sub-zero and low-temperature impact resistance. Compatible with EL8, EM12K, EH14, and EA2 wires.

Typical Applications:

Fillet welding and single or multi-pass butt welding
Suitable for low, medium, and high tensile steels
Single wire, tandem, and multi-wire welding for increased productivity

Drying Requirement:

Redrying recommended at 250-300°C for one hour before use.
