October 25, 2012 - Venvulas Engineering from Vught presents a number of innovations in welding. Besides the new Röwac-SRCS lassystseem new TIG puntlassysteem will a new inverter for AC / DC welding with coated welding electrodes, a new compact water-cooled welding torch and a new hechtlassysteem TIG to see.
The new Röwac-SRCS welding torch with integrated cooling / fume extraction is through Development of a 3-in-1 welding system, which Venvulas last year a prototype at the position showed in Gorinchem. It was still an air cooling system with Peltier elements. That we do not return in the new Röwac-SRCS system. Along with a patented koperlitze round wire conductor, the power developed in the torch and heat simultaneously with the welding fume extraction. With the new air-cooled torch, tested in practice include IHC Beaver Dredgers in Sliedrecht, can be welded. With a welding current of 270 A continuous Almost all welding functions can now be performed smoothly. The source extraction, the welder maximum freedom of movement. He can make gauges easy, while wearing a helmet with air supply is not necessary. In addition, teletec this system also makes a positive contribution to the overall indoor environment because the exhaust air at the source containing the fumes (and the residual heat) after microfiltration is returned into the room clean again. Because central exhaust is actually redundant, no heat thus have to disappear so that the Röwac-SRCS system also makes a significant contribution to reducing energy costs. Lake from space For welding preheated constructions, where the cooling capacity of the air cooling would not be sufficient Venvulas has developed a new water-cooled torch that is as compact and lightweight as the new air-cooled torch. Other novelties Venvulas also presents a new spot welding tongs for TIG welding machines, a new hechtlassysteem for TIG, the new compact water cooled torch, plus a new AC / DC (AC / DC) welding unit for welding with coated electrodes. Also this latest novelty teletec is special. For welding electrodes is a high efficiency power supply with AC namely still the best solution. The extension of a welding electrode is therefore about 10 percent more, and the so-called skew burning does not occur. When welding with AC The old single-phase welders are missed by experienced welders, but may open because teletec of the high AC voltage no longer be used. The power of these machines is no longer of this time with an efficiency of 50%. Röwac Venvulas provides for the development of the 400 Ampere AC \\ DC source in the needs of the electrode welders. The power source is a modern welding inverter with an efficiency of 95 percent. TIG innovations But other innovations bring both technical improvements and financial savings within range. TIG spot welding electrode with the new sheet metal parts can for example be connected more quickly, with the advantage that there is less and less heat is introduced plastic deformation occurs. With the new TIG hechtlassysteem on the other hand, structural parts can easily be attached (before being canceled) without the need to carry. Additional filler material to the tack-welding to each other This means that the welder has a free hand in order to position and then to connect. With the TIG hechtlassysteem mutually the parts relative to each other Filler metal should be used, the parts must be first put clamps on each other, which is no longer needed now, what speed and efficiency-enhancing work.
