  • Page 15: User Responsibility

    USER RESPONSIBILITY Because design, fabrication, erection and cutting vari- ables affect the results obtained in applying this type of information, the serviceability of a product or struc- ture is the responsibility of the user. Variation such as plate chemistry, plate surface condition (oil, scale), plate thickness, preheat, quench, gas type, gas flow rate and equipment may produce results different than those expected.

  • Page 16: Cutting Capability

    CUTTING CAPABILITY The PRO-CUT 55 is rated at 55 amps, at 50% duty cycle on a 10 minute basis (runs 55 amps for 5 minutes, then idling for 5 minutes) or 40 amps, at 100% duty cycle (continuous use). If the duty cycle is exceeded, a thermal protector will shut off the output of the machine until it cools to the normal operating temperature.
