  • Welding Machines : Safety The use of welding machines require some basic safety consideration. When electric generators powered by internal combustion engines are used inside buildings or in confined areas, the engine exhaust must be conducted to the outside atmosphere. Check the welding equipment to make sure the electrode connections and the insulation on... Read more >>
  • Electric Welding Circuits a. A shock hazard is associated with all electrical equipment, including extension lights, electric hand tools, and all types of electrically powered machinery. Ordinary household voltage (115 V) is higher than the output voltage of a conventional arc welding machine. b. Although the ac and dc open circuit voltages are... Read more >>
