SHARC160 ARC250B ARC320 ARC400 ARC500 are the portable welding machines which made by Shanghao company whom take the most advanced MOSFET Inverter technology in the world.
  
The frequency conversion type is popular in the international market for the welding machines.  Its principle is to utilize the high-power switch MOSFET tube to turning 50Hz/60Hz worker into high frequency (frequency can reach above 100KHz), depressurization rectification again. Modulate through pulse width technology (PWM ) output the very high-power available for welding, because of utilizing the switch power inverter technology , the weight of the main voltage transformer , and the measurement of the machine drop by a large margin , efficiency improves by 30%, steady , reliable , light , energy-conservation, silence, the appearance of the inverter welder is praised as a revolution that is an industry of a welder by the expert.
The features of the Shanghao company's arc welding machine series is: High-efficient , energy-conservation , light and portable, and good for moving users, the electric arc is steady, it is easy to control to dissolve the pool, light and high unloaded voltage and better energy thrust are compensated, have wide use range , such as – sky working, field working, and in-door / out-door embellishing. In comparing to the same level machines in the field, the most features of this series are small, light, and easy operation.
