GYS SETS DOWN WELDING TECHNOLOGY MARKER

In 2009 a new high technology R&D Centre was opened as part of the Company’s R&D strategy and one major development from this investment has been the introduction of Power Factor Correction and Flexible Voltage technology across a range of MMA. TIG and Plasma machines.

Power Factor Correction (PFC) technology offers the user a host of benefits, not least in reducing power consumption. The requirement for less power also allows the user to weld at higher levels on a lower power supply - a real world advantage when you consider that the most prevalent power supply in the UK is just 13 Amps. Using GYS’s PFC equipped MMA machines will allow high duty cycle welding at 160amps (sufficient for 4mm rods) on a regular 13 Amp power supply, whereas normally one would expect to have to find a 16 Amp power supply. Normally a 160A machine without PFC, is capable of welding only 3.2mm electrodes at 125A using a 13 Amp fused plug.

What is Power Factor Correction? Inside electrical cables energy travels at various frequencies. In the UK, we use energy at 50Hz, but in fact up to 25% 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 frequencies (also called harmonics) and a significant amount of energy travels at these frequencies. Welding equipment without PFC technology can only draw the energy at 50Hz, which is not very efficient, whilst equipment with PFC technology is able to draw all the energy that is available from all the frequency levels.

GYS is also equipping machines with Flexible Voltage (FV) technology. GYS FV machines can operate at any voltage in the range 85V-265V. Ideal for 110V applications and whenever there is a likelihood of variations in voltage, for example on site with a generator and maybe with long extension leads, With the combined technology of PFC and FV welding performance can be significantly enhanced where there is only a suboptimal power source available. For example the GYSMI 196 FV is capable of welding 3.2mm electrodes on 110V on very long extension leads.

Currently these technologies are incorporated into the GYS range of inverter MMA. TIG and Plasma machines - the GYSMI195, a 230V 160Amp MMA machine, the GYSMI 196FV, a MMA machine and Master 200FV, a 200 Amp PFC and FV MMA/TIG inverter, the TIG200DC HF FV and TIG 207AC/DC HF FV TIG machines as well as the Plasma Cutter 31FV.
