RH-400 Description: ARC WELDING MACHINE RH-400 OF DIRECT CURRENT OR DC CURRENT FOR MEDIUM SIZE JOBS. Ideal for contractors, metal manufacturing shops, shipyards and mines that require high duty cycle, for medium size jobs. The RH-400 is adequate for welding with all types of coated electrodes up to 1/4” diameter in E-6011 and up to 3/16” diameter in 7018. Key features: Provides DC current through a three-phase diode bridge, so it can be used with all types of electrodes up to 1/4” and up to 3/16” and weld all types of materials. - The arc produced by this welding machine is soft and stable in both high range and low range, making very easy to control it, regardless the type of electrode used. - The control AC voltage is rectified and regulated by a potentiometer, and applied to the primary coils of a saturable core reactor varying its saturation and changing its reactance and consequently the welding current. - The transformer core is constructed welding stacked laminations of silicon steel , previously punched with high precision, obtaining so a vibration-free operation. The coils forming the transformer are made of electrolytic copper wire with insulation class 155 °C, either enameled or dipped in epoxy resin, and cured in an oven after a final dipping in epoxy varnish is given to core and coils, to provide them protection against the harsh enviroment. - Manufactured by General construction: Av. F. Bolognesi 510, Santa Anita, Lima – Perú Phone: 511-362-3857 - Fax: 511-362-4052 e-mail: [email protected] http://www.soldadorasandinas.com After the metal enclosure is properly treated to resist corrosion, fine baked paint is applied. Its removable cover allows easy access into the machine for efficient maintenance. All control elements are located on the front panel, for easy and convenient access and for protection against accidental hits. Our machines comply with the Peruvian Technical Standard NTP 370.021.2004 and with NEMA EW1:1999 Standards Soldadoras Andinas S.A. is constantly improving its products, and therefore reserves its right to alter designs and/or technical specifications without prior notice. The carryall has two casters and two fixed wheels, moving the equipment around. that facilitate Standard supply: Electrode holder. - Extra flexible welding cables. - Welding helmet with flip back front lenses. - Earth clamp and cable. - Carryall with two casters and two fixed wheels. - ONE YEAR WARRANTY Technical Specifications: Model Nominal Output Current Amperage Range Maximun open circuit voltage Nominal Primary Amperage for 220/380/440 V Primary Input Power Dimensions RH-400/600 Net Weight RH-400 400 A @ 36 V 20 – 280 200 – 500 80 80/47/40 30.2 / 20 Length: 940 Width: 620 Height: 945 217 Amp.
