PWM’s electro-pneumatic EP500 rod welder, one of the company’s best-selling machines, has a capacity of 5mm to 12.5mm (0.197" to 0.492") copper and 5mm to 15mm (0.197" and 0.59") aluminium. PWM will also exhibit two portable air/ hydraulic powered models, the HP100 and HP200 for wire sizes 1mm to 6.50mm (0.039" to 0.256") as well as a range of manually-operated cold welders for wire sizes 0.1mm to 5mm (0.0039" to 0.197").

➣➢➣ Constructed of stainless and high nickel alloy steels, this modularly constructed burner o ers an extended operating lifespan and reduced maintenance. QED specialises in equipment for heat-treating, cleaning and coating of steel wire. Custom designed and built, the high-speed lines are for galvanising, Galfan®, patenting, annealing and oil tempering processes. Combining innovative design concepts with 30 years practical experience, QED has developed a range of products and equipment that is both technologically advanced and ruggedly dependable. With a view to improved e ciency and to minimise environmental impact, the company has developed the dual loop pressure control combustion system. This system maintains a steady output and close air-gas ratio. This patented combustion control system is used on all the company’s multiple burner furnaces. QED has recently upgraded its proven uidbed technology with proportional, closed-loop feedback and mass ow controls. The Siemens PLC-based system provides much higher thermal e ciency and lower fuel costs than previous systems. Its uidbeds operate from DV=120 to DV=240 and from 1.5t/h to 8t/h production. The latest development in galvanising furnaces is the advanced recuperative technology mark 4 immersion burner. This burner o ers dramatically higher combustion e ciency from a double pass pre-heat design with extended heat-transfer area. granulated particles of the conditioned lubricant allowing the customer to optimise the lubricant performance in the die box. The LCM800 machines are located in well-known wire producers. Depending on wire drawing practices PWT has been able to condition between 45 and 95 per cent of the used lubricant. This means companies reduce their purchase costs and waste disposal costs. Die life is often extended and in many cases higher wire drawing run rates achieved. The overall cost per tonne reduction adds signi cant bottom line improvements for companies. PWT Ltd – New Zealand Website : www.pwt-leetswire.com QEDWire Lines Stand: 12A25

Within one hour of starting a wire drawing machine, the lubrication of the wire being drawn starts to deteriorate. The level of burnt lubricant and metallic particles continuously increases in the die box over time until the point of complete lubrication failure can occur. Often the results are reduced die life, stressing of the steel surface or even reduced productivity due to having to run machines at lower running speeds to overcome the issues.

Traditionally the best method used to overcome these issues is to regularly replace the lubricant in the die box. However this proves expensive as the cost of lubricant consumption and the cost of waste disposal is high. The LCM800 series machine from PWT is used to condition lubricant in the drawing of steel wire. It allows high and low carbon steel wire manufacturers to maximise production by providing good lubrication in the drawing process. The LCM800 machine can be used with calcium or sodium-based lubricants. The LCM 800 series machine takes the used lubricant from the die box and removes the burnt lubrication and metallic particles in its specially designed magnet chamber. The remaining good lubricant is then passed through a granulator system which can adjust the mix of ne to course
