  • The asynchronous brushless generator has no brushes, rings or rotating windings on the rotor, that results to the exceptional reliability while working under the very extreme operating conditions.
  • It delivers superior DC for four independently controlled arcs.
  • One -4×250/5,5 can simultaneously power up to 4 welders (250 A/32 V) or 2 welders (400 A/32 V).
  • It provides added value at the job site by delivering up to 5,500 watts of AC auxiliary power for lights, grinders and other common tools.
  • It allows to weld and have access to AC power simultaneously the full 5,500 watts can be delivered while welding.
  • Reduces number of machines on jobsite, decreases transportation and maintenance costs.
  • Rated for the conditions of the moderate climate with the ambient air temperature –49°F (–45°) to 113°F (+45°) and the relative humidity of air up to 98% at a temperature of 59°F (15°).
  • Attractive and durable red finish paint.
  • One year MERIDIAN warranty (engine is warranted separately by the manufacturer).
