Install and Set Up the Plasma Power Supply
- The Powermax45 SYNC system
  The Powermax45 SYNC® is a portable 45 A plasma cutting system that you can use for many handheld and mechanized cutting and gouging applications. The automatic gas and automatic voltage features make it easy to set up and use the system even if you have limited plasma cutting experience.
- Make sure that you have all the components
  It is important to make sure that you have all the components that come with your Powermax SYNC®.
- Hypertherm plasma power supply ratings
- Cutting specifications
- Correct position for the plasma power supply
  Make sure that the plasma power supply is in a safe position and location before you operate the cutting system.
- Connection requirements for electrical power
  Use the Hypertherm® input current ratings to determine conductor sizes for power connection and installation instructions.
  - Requirements for grounding
    To make sure of personal safety and correct operation, and to decrease Electromagnetic Interference (EMI), the plasma power supply must be correctly grounded.
  - Rated output of the plasma power supply
    Wattage output shows a plasma power supply’s cutting power more than its amperage output.
  - Voltage configurations
    The plasma power supply automatically adjusts for correct operation at the current input voltage. You do not have to change or rewire components. But there are tasks you must do for correct installation.
  - Low rated electrical power source considerations
    Make sure that the electrical service is the correct size to operate the plasma power supply at full output and at its rated duty cycle.

Low rated electrical power source considerations

Make sure that the electrical service is the correct size to operate the plasma power supply at full output and at its rated duty cycle.

If you operate the plasma power supply on an electrical service that is rated lower than what is recommended in Voltage configurations, it can be necessary to:

Decrease the cutting current (amperage setting).
Decrease plasma arc stretch. The more you stretch the plasma arc, the more current the system pulls and the more likely you are to overheat the system or trip the circuit breaker.

If you use a 1-phase system with an input voltage of 230 V on a 20 A breaker, the recommended output current is 19 A.


Input voltage	230 V
Input current at rated output (19 A x 155 V = 2.9 kW)	18 A
Input current during arc stretch	19 A
Voltage tolerance	+20% to -15%
