Subarc welders >> Thyristor Control Submerged Arc Welding Equipments >> MZ-1250A
Processes:
SAW, Stick, Gauging, MIG,ESW
Applications:
Mainly used on welding the sheet steel structures. Widely used on a variety of materials such as carbon steel, stainless steel, stainless steel, heat-resistant steel, etc. and used popularly in the industries of shipbuilding, boiler, chemical containers, bridge-building lifting machinery and metallurgical machinery manufacturing.
Superior Performance:
● Excellent welding properties: CC/CV arc characteristics combined with two adaptive feeding modes(constant speed & automatic transmission) delivers excellent welding performance, meeting the different requirements of various SAW processes. The advanced American-style design of power source significantly reduces the influences of the input voltage fluctuations(especially for unbalance t here phases input),assures the consistency of the weld penetration and width even for a long welding bead. As a result, its welding quality is much better than the traditional thyristor submerged arc welding equipments.
●Durable Reliability: silicon-controlled rectifier used in the power source can compensate the input fluctuations rapidly and automatically, delivers a stable arc and easy output current adjustment. The application of powerful SCR and the traditional main transformer provides the power source with durable reliability, make s it can be safety used in various harsh environments.
●High energy and low feeding speed program assures one-time successful arc starting capacity. Unique crater control circuitry significantly eliminates the welding defects in both the starting and the ended position of the welding bead.
● The application of the soft-start design on the control switch of the main AC contactor avoids the impact to the industrial grid when the power source is started.
●Both the wire feeding and the tractor moving speeding are almost not interfered by the fluctuations of the input power and environment temperature.
