◆Use high power discrete IGBT, and can constantly weld welding rods with Φ4.
◆It can start weld under the lowest voltage 120v, and 380v will be not upload.
◆It use the VRD function to forfend the electric shock under the damp environment.
◆80% of components are imported to insure that it can be up the design requirement.
◆It use the proprietary main circuit protective cover.
