SSR 400 / 600
Fully Thyristorised MMA Welding Rectifiers
Esab Easyweld SSR
series, fully thyristorised MMA welding rectifiers are built using state of the art solid state technology and is designed to meet the stringent demands of high quality radiographic welding for today's fabricating industries, including Nuclear Power Plants, Chemical Process Plants, Offshore Work, Defence, Steel Plant, Thermal Power Plants, Mining and Structural Fabrications etc.
  • True, vertical welding current characteristics with higher open circuit voltage
  • Immunity from AC input voltage fluctuation, with builtin overload and thermal cut-out protections
  • Stable arc with regular droplet transfer and elimination of spatter generation
  • Hot start facilities for easy arc striking
  • Effective prevention of electrode freezing
  • Single range current control with remote control facilities
  • Protection against HF interference
  • Excellent reliability with high performance suitable for outdoor, onsite use
  • Lightweight yet robust in construction
  • Increased versatility with better utilisation
  • Low input kVA rating
  • Six phases ripple free DC output gives excellent welding quality
  • Ideal for precise TIG welding with necessary accessories
