I. General Instruction
    HF Series of Permanent-Magnet DC Arc-Welding Generator has such characteristics as small in size, light in weight, convenient in operation, high in efficiency and reliable in quality, etc. It adopts ≥12PS diesel or gasoline engine or 7.5KW electric motor as its dynamic force. And it can also be assembled on tricycle, quadricycle or other motor vehicles to make up movable or stationary welding and generating doubleduty equipment. It has been widely used as power supply for lighting and such AC-DC electrical appliances as electric drill and electric hammer in oil field, mineral exploitation, highway and bridge engineering, pipework, cities and towns, rural area, forest region, pastoral area, fishing port, industries, workshops, frontier sentry, small ship, household, and public places, etc.
    The welding section of this equipment adopts the structure of cathode to ground and bipole output. The welding and generation can be employed separately or simultaneously. The total load can reach the specified capacity in the instruction manual. Furthermore, since it adopts the permanent-magnet structure, the traditional excitation unit has been abolished. During welding, it has such characteristics as wide adjusting range of welding current, easy generating of arc, and stable flameholding, etc. The welding performance has met the national technical standard for AX series arc-welding machine.
