Why Hypertherm Cutter lost current?
If your Hypertherm Cutter is losing current, first check that the consumable parts are in good condition and that the cut-flow gas settings are correct. Also, verify the pierce delay time. Ensure the arc doesn't lose contact with the plate during cutting, which can occur during hole or scrap cutting. For further investigation, consider performing a chopper test (see the Maintenance section).
What to do if Hypertherm HyPerformance Plasma HPR260 Cutter has no arc transfer?
If you're experiencing 'No arc transfer' with your Hypertherm Cutter, first ensure that you're using the correct pierce height. Also, check that your preflow and cut-flow settings are accurate. Inspect the work lead for any damage or loose connections. Finally, perform a current test as described in the Maintenance section.
How to fix gas system error on Hypertherm Cutter?
If your Hypertherm Cutter (Auto Gas Only) is showing a 'Gas system error', verify that cable number 5 (the power supply-to-gas console control cable) is undamaged and correctly connected to PCB3 and the rear of the gas console. Also, verify that cable number 6 (the power supply-to-gas console power cable) is undamaged and properly connected inside the power supply and to the rear of the gas console. Check that D1 (+5 VDC) and D2 (+3.3 VDC) are illuminated on PCB2 inside the gas console, indicating power to PCB2. If power is present at PCB2 and PCB3 and both gas console cables are in good condition, then PCB2 or PCB3 may have failed; use the CAN tester to determine which board needs replacement.
What does precharge time-out mean on Hypertherm HyPerformance Plasma HPR260?
If your Hypertherm Cutter (Auto Gas Only) is experiencing a 'Precharge time-out', it indicates a potential gas restriction in the leads. Check the plasma and shield hoses for any obstructions.
What to do if Hypertherm HyPerformance Plasma HPR260 Cutter lost transfer?
If your Hypertherm Cutter experiences lost transfer, start by checking the condition of the consumable parts and ensuring your cut-flow gas settings are correct. Verify the pierce delay time. Make sure the arc maintains contact with the plate during cutting, especially with hole or scrap cutting. Inspect the work lead for any damage or loose connections. You might also try connecting the work lead directly to the plate. For further diagnostics, a chopper test can be performed (refer to the Maintenance section).
What to do if Hypertherm HyPerformance Plasma HPR260 start lost?
If your Hypertherm Cutter experiences a start lost issue, and you're using a mechanical relay to provide the HPR with a start signal, the relay might be bouncing upon activation or have faulty contacts; consider replacing it. Inspect the interface cable for damage, faulty crimps, or poor electrical connections. If the interface cable is in good condition and a relay isn't driving the start input, the CNC might be dropping the start signal before a steady-state arc is established.
How to fix Hypertherm HyPerformance Plasma HPR260 Cutter lost phase?
If your Hypertherm Cutter shows a 'Lost phase' error, begin by verifying the phase-to-phase voltage to the power supply. Then, disconnect power, remove the cover on the contactor, and inspect the contacts for excessive wear. Check the power cord, contactor, and input to the chopper for loose connections. Inspect the phase loss fuses on the Power Distribution board; replace the board if the fuses are blown. You can also perform a phase loss test (see the Maintenance section).
Why Hypertherm Cutter shows low plasma gas pressure?
If your Hypertherm Cutter displays a 'Low plasma gas pressure' warning, start by inspecting the gas supply pressure and the remaining gas volume in the supply tanks. Verify the gas regulator settings on the gas console against the parameters in the cut charts. Refer to the Installation section for instructions on setting the supply regulators and perform gas leak tests as described in the Maintenance section.
Why Hypertherm HyPerformance Plasma HPR260 Cutter shows hold timeout?
If your Hypertherm Cutter displays a 'Hold timeout' message, start by checking the interface cable for damage, as the hold wires may be short-circuiting inside. Consider that the CNC is maintaining this input, possibly waiting for an IHS complete input from another torch. If the CNC interface cable is good and it's a 1-torch system, try changing PCB3.
How to fix low nitrogen gas pressure on Hypertherm HyPerformance Plasma HPR260 Cutter?
If your Hypertherm Cutter is showing 'Low nitrogen (N2) gas pressure', first ensure that the nitrogen supply is turned on and inspect the gas supply pressure and volume of gas remaining in the supply tanks. Also, verify that the gas regulator is set to 8.27 bar (120 psi). Refer to the Installation section for instructions on setting the supply regulators.
