Arc can transit between intervasl stably with little splash, can form well seam, get nice welding seamAdvanced electric circuit design, reduce damage to power switch, the power elements generate little heat, can obviously increase the duty cycleLight, high efficiency, energy-saving.Its high inverter frequency can reduce power loss obviously, distinct its energy-saving factorWelding curent and voltage can be adjusted continuously, can satisfy the needs of different welding requirementsConcise circuit desing, reliable and complete machine functions, convenient for automatic weldingQuick protection circuit against over current, suitable for continuous workMainly applicable for welding of ferrous metal like carbon steel, low carbon steel and stainless steel; Machines above 350A are widely used in ship-building, automobile, bridge, steel structure. Machine below 250A are specially suitable for welding of thin plate
