Highlights

  • Used in combination with ESABs A2-A6 equipment range and the A2-A6 PEK or A2 PEI process controllers
  • Good arc stability at both high and low arc voltages
  • Adjust and monitor the welding parameters on the power source from the front panel of the process controller (PEK or PEI)
  • Welding current range can be extended by connecting two power sources in parallel for the most demanding applications
  • Ideal for SAW applications such as wind tower components, nuclear power vessels, boilers and ship building applications
  • Ideal for GMAW applications such as welding the root pass in heavy pipe production

Process

  • Cladding
  • SAW - Submerged Arc Welding
  • GMAW (MIG/MAG)
  • Air Carbon Gouging
