More power in a smaller cabinet EFD Induction has introduced the world’s first 1,000kW single-cabinet induction welder – the first of its kind in terms of power-to-volume ratio. According to the company the new Weldac 1,000kW offers less power consumption, better weld quality and easier operation. carbon high-strength steel, stainless steel and aluminium. The Weldac builds upon EFD’s extensive process and applications knowledge and decades of international experience in solving tough welding challenges.

footprint from EFD’s previous design makes it even easier to install and maintain. Faster installation results in reduced costs and retrofit downtime as well as reduced delivery time on higher power. Running costs are also lower due to low power consumption. What is known as ‘harmonic distortion’ is a growing concern, because the proliferation of non-linear loads causes disturbances that impair equipment performance and affect total voltage supply. A 12-pulse rectifier reduces this by 50 per cent, resulting in a more even temperature and a better weld quality. The Weldac offers high total efficiency measured from the mains inlet to the weld coil. In combination with the 12-pulse rectifier, this minimises power and cooling-water consumption. The Weldac 1,000kW has longer coil lifetime, resulting in minimal scrap and re-working of material. This further strengthens EFD Induction’s eco- friendly welding policy. The Weldac 1,000kW is easy to operate, with a minimum of manual settings. Operation is via an easy-to- use control panel. Minimal operator intervention results in fewer operator errors and, consequently, increased throughput and efficiency.

The Weldac covers a wide range of power sizes: from 50kW low-power welders up to 2,200kW high-power welders. All Weldac systems are backed by EFD Induction’s extensive worldwide service and support programme. A modular design makes Weldac 1,000kW compact, saving valuable floor space and simplifying in-line integration and retrofitting. A 34 per cent smaller

EFD Induction specialises in developing equipment with the best power-to-volume ratio possible. With the introduction of Weldac 600-1,000kW it can now offer up to 1,000kW in a single- cabinet solution. Weldac is part of EFD Induction’s family of high-output, solid-state tube and pipe welders. It is a proven solution used over many years for welding low-

end at a time. The steel deburring brushes rotate at high RPM while the entire brush head rotates a full 360 o to deburr every edge and corner. The burrs from cut off saws and shear blades are also removed, for safer part handling. Large, more automatic machines are also available, which

can be loaded directly from the mill or manually. The parts are then picked up one at a time and transferred through the machine by chain driven fingers.

KENT has developed a new Burrmaster Rotoburr to complement its full line of tube end deburring machines. The new system is designed to remove the burr from the ends of tube, roll form and welded shapes. The new, more economical machine is manually loaded with deburrs one
