Decrease output current and arc stretch for lower rated electrical service
If you operate the power supply on an electrical service rated lower than what is recommended in
Voltage configurations on page 28, you may need to:
 Turn down the cutting current (amperage setting). See Step 6 – Set mode and adjust
output current (amperage) on page 51.
 Avoid stretching the plasma arc for prolonged periods. The more you stretch the plasma arc,
the more current the system draws and the more likely you are to overheat the system or trip
the circuit breaker.
Example: 230 V input on 20 A electrical service
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.
CAUTION
Do not operate this system on a 15 A or 16 A circuit breaker.
Input voltage 230 V
Input current at rated output (19 A x 145 V = 2.8 kW) 18 A
Input current at arc stretch 19 A
Voltage tolerance +10% / -10%
