Cor-a-Rosta Flux Cored Wires for Stainless Steel Applications.
Up to 35% increase in productivity comparing to MIG
Up to 70% increase in productivity comparing to MMA

In today’s world of increased competitiveness and high pressure on fabricators to reduce costs using flux cored wires for your welding jobs can provide competitive edge.
Cor-a-Rosta – Lincoln Electric’s range of stainless steel flux cored wires - is well established in many markets, however, many fabricators are not fully exploiting all the benefits and advantages it offers.
Cor-a-Rosta wires have been designed to provide optimum welding characteristics in either the down hand or positional welding and combine the productivity of MIG/GMA with the operability and bead appearance of MMA/SMAW electrodes. This alone would justify the decision to switch to Flux Cored Arc Welding process. But there is more…
Higher electrode efficiency, easy work with higher currents and duty cycle make Cor-a-Rosta wires more competitive against MMA /SMAW process.
From the other side, semi-automatic CV power sources for Flux Arc Welding are easily available. The most popular shielding gases may be used (CO2, Ar-CO2 blends). Optimal slag system helps to achieve regular weld geometry and to weld with higher wire feed speeds. Higher current density eliminates typical disadvantages of MIG/GMAW welding (lack of penetration, cold laps) and significantly contributes to the increase in deposition rate especially in positional welding.
Many additional benefits - such as low cost, ease of use and lower welder skills needed, excellent weld appearance and radiographic quality – have all contributed to the success of Cor-A-Rosta wires. They are available in the most common stainless steel grades and the increased productivity is the main factor explaining their successful application in general fabrication, production of food and brewery equipment, petrochemical and chemical industry, offshore oil and gas or civil architectural constructions.
