Gas shielded arc welding

名字:KR-350/500

性能特点:


●The unique arc striking circuit guarantees the success rate of high arc ignition, and the successful rate of arc ignition in any working condition under the technical specification is 100%, which can be matched with various forms of automatic welding special machine;

●H grade insulation, the main transformer, reactor coil using the United States DuPont Co's high performance Nomex insulation paper, high insulation strength, high temperature resistance, good dust;
●Shell protection grade IP21S, welding machine main circuit and control circuit to achieve the physical isolation, effectively prevent the main circuit of the control circuit and the influence of interference, drops, the dust of the overall structure, moisture and protection, can adapt to the harsh environment operation;
●7 to 6 minutes after the end of the welding, the main circuit is disconnected, and the loss of energy consumption is reduced;
●Unique control circuit to meet benevolence Co / MAG welding short circuit transition and transition of the jet of arc dynamic characteristics of technical requirements, welding spatter small, excellent welding performance, weld appearance;
●Improve the over flow, overheat protection, unique secondary short circuit protection function, under the condition of short-circuit obstacle unburned loss thyristors and transformer, short circuit faults remove automatically return to a normal state.
●Solid cored wire and gate.

application area

●Light industry, industry.
●Shipbuilding, automobile, construction, steel, oil pipeline etc..
