n a Welding rectifier, the primary winding of the transformer is always energized. Even if welding is not going on, the machine always draws some current from the supply to meet the no load losses. Although arc welding can be performed safely, there are circumstances where there is a substantial risk of electric shock where workers need to weld in tight areas where heat and humidity can be a factor. The severity of the shock received when a person becomes part of an electric circuit is affected by several factors. These include: 1) The amount of current flowing through the body of the person. 2) The path of the current through the body, and the length of time the body is in the circuit. 3) The current level (measured in mA, milli-amperes) is a function of both the voltage at the electrodes and the resistance of the person's body. This energy saving cum voltage reducing device is designed to operate on any constant DC current welding machine (stick welder) with an open circuit voltage of 60 - 100 volts. Until the arc is struck the output voltage is maintained lesser than 12 volts. This prevents the operator from receiving a shock. Also the input supply to primary of transformer is cut when the output voltage is 12V, hence there is no power loss during this idle condition. Thus it performs energy saving action. About Energy Saving cum Voltage reducing device and its working principle: This device is connected between the input supply of the welding rectifier and it continuously monitor the welding output terminal voltage. On striking the arc, full selected output is available instantaneously. Energy saving cum voltage reducing device senses the stoppage in welding and cuts off the supply to the primary winding within the predetermined time (approx. 30 second to 5 minute) and safe voltage of 12 Volts will be appeared on the Welding terminals until the next arc strike. This device reenergizes the primary winding instantly without affecting the welding quality as soon as the electrode comes in contact with the job.     APPLICATIONS SALIENT FEATURES ·    Energy Saving application. ·    Confined Spaces such as vessels, mine shafts ·    Wet or damp conditions. ·    Hot and humid conditions. ·    Working at heights. ·    Safe voltage to protect from electric shock when welding is not going on. ·    Instant Start of welding operation ·    Reduction in machine heating ·    Compact assembly. ·    Easy for mounting. ·    Welding performance unaffected

Since 2008, Boosung Engineering has been manufacturing the waste heat recovery dryer called E-Saver. E-Saver is a creation exploiting low temperature waste energy by recycling the heat only, without other heat transfer media. This system is designed for heat recovery from drying process of flexible package printing, coating and laminating. Following are the Key Features of E-Saver Saves about 60 – 80 % of energy resulting in direct reduction of total production cost. Reduces Residual Solvent Increases Cooling Efficiency Reduced VOC Emission due to reduction in exhaust temperature
