includes handheld and mechanised plasma cutters and consumables, as well as CNC motion and height controls. Hypertherm Europe – Netherlands hteurope.info@hypertherm.com www.hypertherm.com/eu Manufacturing to a wide range of standards Conros Group is a diversified company, with activities including steel manufacturing and trading. The Group has manufacturing plants at Khopoli, Maharashtra State, India, currently manufacturing black and galvanised ERW steel pipes, tubes and hollow sections from ½" to 4". The Group is expanding its capacities by introducing new state-of-art equipment, being imported from USA and Europe, for manufacturing larger diameter pipes and API line pipes from 2½" to 8" diameter, and square and rectangular hollow structural sections. Conros manufactures tubular pipes in ½" to 4" diameter, and square and rectangular sections from 15x15mm to 100x100mm, under international and Indian standards including: • IS: 1239, 3589, 9295, 4923, 1978 (line pipes), 1161, 4270, 3601 • ASTM: A 53 (Sch 10 to Sch 80), A500, A135, A795, A513, in Gr A & B • DIN: 2439, 2440, 2441 (galvanising to 2444), 2393, 2394 • BS: 1387, 879 • EN: 39, 10210, 11960, 11961 • JIS: G3442, G3444, G3466, G3472 • ISO: ISO/R-65 Thecompany’supcomingdevelopments include API 5L accreditation (for 3" to 8" up to Grade X70) by December 2008, and UL listing (ie UL 6, UL 797 and UL 1242 for conduits) also by December 2008. FM approval (for fire fighting systems) and CE marking approval (for European markets) are both under proposal.

Ultimate welding chamber The Black Diamond welding chamber from Weldlogic Europe features a large work space with stainless steel work surface; large transfer load-lock with automatic timed gas purge; and oxygen meter display in parts per million for assured gas quality welding. The workstation is ready to operate, only requiring the fitting of the user’s weld system and connection to gas and power. It can be installed on bench top for standing or low seated operation.

Other features include attainable gas purity below 5ppm oxygen for bright nickel weld finish, and fully automatic load-lock gas management control system.

The Black Diamond welding chamber provides a system design that is a cost-effective solution to TIG welding materials reactive to atmospheric contamination, and high end materials that require a controlled and verified welding environment for minimal defect and tarnished work pieces. It is designed with functionality to give welders the tools they need to achieve proficiency through control. The bench top mounted workstation has two 6" x 8" oval polypropylene

glove ports mounted below a polycarbonate window 10mm thick. The weld chamber is manufactured in virtually indestructible textured copolymer, and is fully welded and leak tested. The chamber is fitted with a stainless steel floor plate over box length 950mm and depth 550 within a height of 650mm. A rear panel is removable for occasional cleaning or installing large welding aids. Weld cable connectors are ready for hook up to torch, ground and power source, including gas feedthrough fitting for torch shield gas. The load-lock is constructed in the same copolymer, and is fully welded and leak tested. Inner and outer doors of the same material are reinforced for ensuring effective sealing with captive ‘O’ ring seal. The doors operate using lever latch clamping. Rectangular design provides a 380mm length load-lock with 280mm depth and 280mm height for easy transfer of most large weld pieces. A stainless steel floor plate is supplied for ease of weld piece transfers. A push button initiates a gas purge to remove air and replace with Argon gas for transfer of weld pieces into the weld chamber without degrading the main chamber Argon gas purity. Set time and gas flow ensures quality controlled transfer with minimum gas usage, and an audible sounder announces completion of the gas purge process. The glove box workstation is equipped with a twin fluorescent light, externally top mounted over a polycarbonate window to provide over 700 lux of lighting within the glove box at the working plane. The weld chamber is supplied with a gas flow regulating valve and flow gauge to adjust amount of Argon passing through. This regulation allows for the chamber to be set at a flow rate to reduce and hold the oxygen levels to below 5 parts per million. Argon gas consumption varies according to use but averages below 10 litres per minute during operation and 1 to 2 litres per minute on standby. Initial gas purge of the weld chamber from air down to weld quality is less than 60 minutes at less than 50 litres per minute gas flow.
