Submerged Arc Welding Machine

  • The submerged arc welding machines or ESAB CPRA 800(S) and ESAB CPRA 1200(S) rectifier power sources are designed to provide a direct current supply to automatic welding heads for submerged arc and MIG/CO2 process. 
  • These power sources are meant for use with electronically controlled welding heads and have flat output characteristics. 
  • The power sources also provide auxiliary power circuitry for running the welding heads and provide heater supply for use with CO2 when needed; the auxiliary power is available through two sockets provided on the front panel.
  • The components of the welding rectifier are housed in a steel framework, the four sides and top of which are covered by collapsible sheet metal panels.
  • The front of the set is a sheet metal panel having all the push buttons, indicating lamps, voltmeter and power ‘On’ and ‘Off’ MCB mounted in the top portion of the panel. 
  • Its features include: capacity for continuous use; setting of arc voltage throughout the entire minimum or maximum range with fine control in steps; overload protection.
