Cut-off blades KENT Corporation, in cooperation with a tube-producing customer, has developed a special cut-off blade for use in the most difficult applications. The new blade resulted in an increase in life of over 200% over the standard blade. Kent Corporation, the tube producer, and the blade manufacturer achieved the results through a vigorous testing programme. This

Fresh era in MIG/MAG welding EWM’s alpha Q system provides six full- scale welding processes in one machine: coldArc ® and forceArc ® , MIG/MAG pulse and standard processes, TIG (liftArc) and MMA welding. It is possible to switch between applications at any time, as well as to combine different processes, while retaining seam quality and efficiency. The system allows the thinnest of panels to be joined at low heat, in addition to welding and brazing new materials and mixed connections. EWM states that the system’s excellent gap bridging allows root passes to be handled easily and safely, and that deep fusion penetration, simple handling and a high welding speed mean the high pressure, forced welding arc can be used to weld thick panels while claiming saved production costs of up to 50%. This is provided by a single machine combining the EWM coldArc and forceArc processes, rounded off by a pulse welding arc. These welding processes allow all seam types to be realised from one power source, and result in a welding seam with such low spatter that post weld work is virtually unnecessary. The alpha Q range – 330, 351 and 551 – provides a system that can be flexibly configured for specific applications, from portable, modular or compact to mobile. For alternating between coldArc and forceArc welding, a twin case or two individual wire feed units are available, so the user always has the required filler wire and gas.

technical approach to increasing blade life is available free to all blade customers to make sure the blade they are using is optimised for their application. A new coating SNB is available as well and has shown double to 10 times the life on applications where excessive heat is created.
