  • Welding Current

    300

    Suitable for professional use on thick metals, such as steel or cast iron constructions.

  • Duty Cycle

    The Duty Cycle is the portion of a ten-minute period that a welding machine can operate continuously at maximum Amperes before it needs to stop and cool down.

    2.

    For example, a welding machine with a maximum Amperage of 200 A and a Duty Cycle of 30% can operate continuously at 200 A for 3 minutes before it needs to stop.
