PFC And FV Technology For Research And Development GYS, a welding gear and battery charger manufacturer, has invested in Power Factor Correction (PFC) and Flexible Voltage (FV) technology across a range of MMA for its research-and-development centre. PFC technology offers the user a range of benefits, including a reduction in power consumption. The requirement for less power also allows the user to weld at higher levels on a lower power supply. Using GYS's PFC-equipped MMA machines will allow high-duty-cycle welding at 160A (sufficient for 4mm rods) on a regular 13A power supply. Normally, a 160A machine without PFC is capable of welding only 3.2mm electrodes at 125A using a 13A fused plug. Inside electrical cables, energy travels at various frequencies. In the UK, we use energy at 50Hz, but up to 25 per cent of that energy travels at either higher or lower frequencies called diffractions. Mathematical models show that all of these diffractions add to each other for certain fre...
