2-2. Specifications For Torch

Air-cooled torch for plasma arc cutting (PAC)

35% duty cycle

Gas flow/pressure: 1 SCFM (28.3 L/min) at 50 PSI (345 kPa)

Safety interlock devices shut down power source

Safety trigger guard

Cutting capacity: see Section 2-1

2-3. Duty Cycle And Overheating

Duty Cycle is percentage of 10 min- utes that unit can cut at rated load without overheating.

If unit overheats, thermostat(s) opens, output stops, Temperature trouble light goes On, and cooling fan runs. Wait fifteen minutes for unit to cool or temperature light to go off. Reduce amperage or duty cycle before cutting or gouging.

Y Exceeding duty cycle can damage unit and void warranty.
