The defining feature of FCAW is the tubular wire construction. Unlike solid wire, the core contains granular flux. This allows the process to offer deposition rates and mechanical properties that often exceed what is possible with solid wire GMAW.
FCAW produces more smoke than MIG. Proper ventilation or fume extraction is mandatory. Safety Requirements
: FCAW combines the continuous wire feed of MIG welding with the penetrating capabilities and slag protection of Stick welding. The Tubular Electrode
