1. Verify that coolant filters are in good condition.
2. Verify that there are no restrictions in the coolant system.
1. Verify that the consumable parts are in good condition.
2. Verify proper pre-flow and cut-flow settings.
3. Perform leak test.
4. Verify spark across spark gap.
5. Inspect CON1 and pilot arc relay for excessive wear.
6. Perform gas flow test (see
Maintenance
section).
7. Perform torch lead test (see
Maintenance
section).
8. Perform start circuit test (see
Maintenance
section).
9. Perform chopper test (see
Maintenance
section).
1. Verify proper pierce height.
2. Verify proper pre-flow and cut-flow settings.
3. Inspect work lead for damage or loose connections.
4. Perform current test (see
Maintenance
section).
1. Verify that the consumable parts are in good condition.
2. Verify proper cut-flow gas settings.
3. Verify pierce delay time.
4. Verify arc did not lose contact with plate while cutting (hole
cutting, scrap cutting, etc).
5. Perform chopper test (see
Maintenance
section).
1. Verify that the consumable parts are in good condition.
2. Verify proper cut-flow gas settings.
3. Verify pierce delay time.
4. Verify arc did not loose contact with plate while cutting (hole
cutting, scrap cutting, etc).
5. Inspect work lead for damage or loose connections.
6. Try connecting work lead directly to the plate.
7. Perform chopper test (see
Maintenance
section).
1. Verify phase-to-phase voltage to power supply.
2. Disconnect power to power supply, remove cover on
contactor and inspect contacts for excessive wear.
3. Inspect power cord, contactor, and input to chopper for loose
connections.
4. Inspect phase loss fuses on Power Distribution board.
Replace board if fuses are blown.
5. Perform phase loss test (see
Maintenance
section).
1. If a mechanical relay is being used to provide the HPR with a
start signal, this relay is either bouncing when activated or the
contacts are faulty. Replace the relay.
2. Inspect interface cable for damage; faulty crimps, or poor
electrical connections.
3. If interface cable is good and a relay is not driving the start
input, the CNC is dropping the start signal before a steady state
arc has been established.
18

exceeded 13.79 bar (200
psi).
20 No pilot arc
No current detected from
chopper at ignition and
before 1-sec timeout.
21
No arc
transfer
No current detected on
work lead 500 milli-
seconds after pilot arc
current was established.
24 Lost current
Lost current from chopper
after transfer.
31 Start lost
Start signal was received
and then lost before an arc
was established.
26 Lost transfer
After transfer lost the
transfer signal.
27 Lost phase
Phase imbalance to
chopper after contactor
engaged or while cutting.
