Kyndill Control Support

Please use the following the to troubleshoot issues you may be having with with your Kyndill Controller.

No Display

If you just powered on your Voltage Controller and show a blank display check LED’s on Lifter Station Motor (located between motor connectors). Are either of the two LED’s showing Red or Green?


  1. Check the AC line cord is properly seated in the back panel of your console and electrical outlet.
  2. Verify the On/Off rocker switch next to the AC inlet is on.
  3. Is AC power available at the electrical outlet?
  4. Check the fuse located in the fuse drawer next to the AC inlet.

If problem persists, contact Technical Support.

Arc Voltage Errors

If the torch is diving into the material it could be that the arc voltage is set too low. The torch will automatically search for the voltage it has been set to maintain, thus it will look for it in the material or closer to the power source to maintain its voltage level. To correct this, increase the voltage setting 1 to 2 volts higher for starters, and continue to raise it if necessary.

If the Arc Voltage is set too high, the arc may actually spike up and stay further way from the material than normal, or may step upward, and will lose the arc altogether. The initial arc will penetrate the metal but it may not be able to maintain this high of a voltage setting, thus the AVHC inevitably moves too high off the material and the arc is lost and will rise to the top of its travel. To correct this, a decrease the voltage setting 1 to 2 volts lower to start, and continue to lower if necessary.

Make sure that the Raw Arc Voltage take-off wires are connected to the DC+ and DC – terminals inside your plasma cutter.

If problem persists, contact Technical Support.

Torch Misfires/Not Firing

Check the Compressor

The air pressure fed into your plasma cutter must be in the range of 90 to 120 psi in order to consistently create plasma in a given range of 65 to 90 psi. If you are using a compressor to supply air to more than one line at a time, be sure that it can maintain a level of pressure to allow all lines to be consistently supplied, otherwise your tank may be draining faster than the compressor can recharge the holding tank. Consider switching to a dedicated tank for you plasma operation.

In the process of creating compressed air, water condensation collects in your holding tank. This condensation can also leak into the line supplying air to your plasma cutter. In most plasma torch systems, a water separator valve is utilized to allow the collection and drainage of excess condensation passing through the air line. Even with this preventive measure, condensation can still bleed into the torch line itself, and cause misfiring, or total system failures. To ensure that the excess condensation is removed, drain your holding tanks and water separator often, or whenever condensation is present. This will help to prevent Ignition failures.

Check the Consumables

In the torch head the electrode must move up and down freely for the torch to fire. The plasma unit looks for continuity between the electrode tip and nozzle before the torch will turn on the air and initiate the arc. The air forces the electrode up away from the nozzle to make electrical contact with another contact point in torch body permitting current flow to the electrode.

If there is slag or foreign matter keeping the electrode from making electrical contact with the nozzle when the air is off the plasma unit will alarm and not fire. The alarm will reset after 10 seconds. If the electrode cannot slide up freely and make electrical contact after the air is turned on, the torch will fire with a lowered amperage, or misfire completely.

The Retaining cap for the consumables and swirl ring should only be finger tight, if the cap is over tightened the electrode may not move freely enough to function properly.

If problem persists, contact Technical Support.

I/O Monitor Test

Inputs: OK (press) / Start (jump) / OK to Move (jump) / Up (press) / Down (press) / Corner (jump) / Cut (press & hold 1 sec)

Outputs: Torch/Fault/Pierce/Cut LED (will remain a (1)b/c LED remains on)

Analog: (will read the voltage applied at Voltage input)

When you enter the I/O monitor screen, you will notice 7 (0's) on the input line and 4 (0's) on the output line. OK (press) signifies the first (0) and Cut (press & hold 1 sec) signifies the last or 7th (0) on the input line. Same applies for the Output line where Torch represents the 1st (0) and Cut LED represents the 4th (0).

Pressing the OK button will effectively change the 1st (0) on the line to a (1) while also activating the Torch Output by changing the 1st (0) on the outpout line to a (1). You will also hear a relay clicking to confirm each output (Torch, Fault & Pierce) are functioning properly. You can test the Start (2nd 0), OK to Move (3rd 0) and Corner (6th 0) are functioning poperly by jumping their respective pins and checking to see if their positions are switching from (0) to (1). Their will/should be no effect to the output line.

Motor / Controller Communication (Echo Test)

Echo Testing is a useful tool for troubleshooting communications between your controller and motor.

For instance, if a "No Motor Detected" is displayed on the screen, using the Echo Test will allow you to quickly diagnose whether the issue is within the controller, cable or motor.

TX = Transmit

RX = Receive

To test TX and RX within the controller:

  1. Power unit on while holding the OK button.
  2. Go into Factory menu and navigate to "Perform Echo Test"
  3. Jump TX & RX
  4. Tap the OK button to perform test

If the test is successful, "Echo Success" will appear on your display. This means communicatins within your controller is functioning properly.

If communication is umsuccessful, "Echo Test Fail" will appear on your display.

To test TX & RX through your communications cable, up to the motor, secure "Enclosure Connector" to the enclosure. Perform the same procedure as you did for testing the enclosure TX & RX except this time you want to jump TX & RX at the "Motor Connector" end.

At this point, if the Echo Test fails, your issue would be with the communications cable. If the Echo Test is successful, your issue is within the motor.
