Problem Solution
Inaccurate IHS with nozzle ohmic contact.
1. Check that THC is in Automatic Mode. If not, select Automatic Mode.
2. Check that Nozzle Ohmic Contact is ON (enabled).
3. Check that nozzle ohmic contact wire is not disconnected. Ensure that
the wire is connected at both ends.
4. Check that the torch retaining cap is tight.
6. Check for water on the workpiece. If water is present, use Stall Force
sensing and disable the Ohmic contact.
7. If you are cutting under water, only use Stall Force.
8. Check for coating (oil, plastic, etc.) on the workpiece. If there is a
coating, present, use Stall Force sensing.
8. Check the nozzle and shield, and clean or replace them.
9. Check the work lead connection.
Inaccurate IHS with Stall Force sensing.
1. Check that Nozzle Ohmic Contact is OFF (disabled).
2. Check Transfer Height.
3. Check that Stall Force is not set too high.
4. Check that workpiece is not deflecting excessively. Check the work
table supports under the workpiece.
5. Offset workpiece deflection by adjusting Set Cut Height and Transfer
Height to achieve the desired results.
Torch fails to ignite.
1. Check that the plasma system is operational.
2. Check the Start signal.
3. Check for proper IHS piercing height. Check torch.
4. Check that IHS SYNC is OFF on the control module CNC interface
inputs.
5. Check torch consumables.
6. Verify that the corresponding station is enabled.
Torch arc fails to transfer to workpiece.
1. Check that Transfer is not too high by checking Set Cut Height and
Pierce Height Factor.
2. Check work lead connection.
3. Check torch consumables.
4. Check the Motion signal in the LCD on the control module PCB,
Machine Interface Inputs.
