Flux-cored arc welding. Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply.
LincolnweldÂ® 880M is a basic flux which features industry proven results in multiple pass applications. It is recommended for welding with solid mild steel and low alloy electrodes, as well as Lincoln's LAC series of low alloy flux-cored electrodes. For an excellent AC welding flux - choose LincolnweldÂ® 880M.
