The MF Series Mid-Frequency Spot and Projection Welding Machines are designed to provide advanced welding features for industry use. It is composed of several advanced modules, such as an inverter power source, a dedicated welding controller and welding transformer. Quality import parts are used for the construction of the MD series equipments. The SL-MF110 Controller is designed to provide stable output performance using high performance multi-microcontrollers with 2 channels of Analog-to-Digital Converter circuits. The output power will automatically be adjusted against any changes in input power voltage and temperature. This guarantees high quality welding results. The operation of the equipment is easy to use and user friendly with 8 selectable welding schedules (series). With a low maintenance rate and built to last long, the MD Series Mid-Frequency welding equipments is an perfect equipment to replace expensive import machines.

The Mid-Frequency Welders has the following advantages over the traditional AC welders

1,Energy Saving Comparedwith AC welders, it is more efficient to deliver the same amount of welding energy to the work pieces using mid-frequency inverters.

2,Easy to Integrate Because of the relative lighter weight of mid-frequency transformers, it is easier to integrate with other welding equipments in an automation welding system.

3,Improve power factor, and the cost of welding operations.

4.The nature of DC current helps to reduce electrical and magnetic interference, especially those applications with large secondary current loop. Also the secondary circuit inductance does not lower the welding quality due to the nature of DC welding current.

5,Balanced loading to the 3 phases of power lines.

6,Higher adaptability to any changes from the 3 phase power lines.

7,More precise and faster control using 1000Hz frequency,which is 20 times faster.

8,Faster to achieve program current set point.

9,Capable to weld metals with higher conductivities, such as copper and aluminum.

10,High quality and reliable components are used to reduce service times.

11,Cost Saving made possible due to faster and higher efficient welding.

12.Mid-frequency inverter resistance welding machine.
