MIG WIRE FABSHIELD 21B 1.2MM 4.5KG/SPOOL
Self-Shielded Flux-Cored Welding Wire for All-Position Mild Steel Welding
Product Overview
Fabshield 21B is a premium self-shielded flux-cored arc welding (FCAW-S) wire engineered for high-deposition, single and multi-pass welding on mild and galvanized steel. This 1.2mm diameter wire comes in a convenient 4.5kg spool, making it an ideal choice for fabrication shops, construction sites, structural steel work, and general maintenance and repair welding.
Unlike solid MIG wire, Fabshield 21B requires no external shielding gas — its flux core generates its own protective shielding as it burns, making it perfect for outdoor, windy, or field welding conditions where gas-shielded processes would fail.
Key Features
- Diameter: 1.2mm — ideal for medium-to-heavy gauge steel
- Spool Weight: 4.5kg per spool for extended, uninterrupted welding runs
- Self-Shielded (Gas-less): No shielding gas required — perfect for outdoor and windy environments
- All-Position Welding: Suitable for flat, horizontal, vertical, and overhead positions
- Classification: Typically conforms to AWS A5.20 E71T-11 (self-shielded flux-cored wire standard)
- High Deposition Rate: Faster travel speeds and increased productivity vs. stick electrodes
- Smooth Arc Characteristics: Easy slag removal with minimal spatter
- Versatile Application: Works well on galvanized, painted, rusty, or otherwise contaminated mild steel surfaces
Common Applications
- Structural steel fabrication and erection
- Shipbuilding and heavy equipment repair
- Agricultural and farm equipment welding
- Pipeline and tank construction
- General maintenance, repair, and outdoor construction welding
- Sheet metal and light structural work
Why Choose Fabshield 21B?
Fabshield 21B is trusted by welders for its consistent arc stability, low spatter, and ease of use — even for semi-skilled operators. Its gasless design eliminates the cost and hassle of shielding gas cylinders, reduces setup time, and keeps productivity high on job sites where wind or space constraints make gas shielding impractical.
Recommended Equipment
Best used with a standard MIG welding machine set up for flux-cored (FCAW) operation, DCEN (straight polarity) power connection, and appropriate drive rolls for flux-cored wire feeding.
