4.12.6 Testing Ohmic Probing
1. Make sure that the ohmic probing spade connector is
connected to your torch cap.
Note: You must be using shielded consumables
where the torch cap extends below the nozzle.
If the nozzle contacts the workpiece before the
torch cap, ohmic probing will not work.
2. Switch to the Status tab on your PathPilot controller and
locate the OHMIC TOUCH led. It should be off initially.
3. Touch the ground clamp lead from the plasma source to
the torch cap. You should see the LED switch to green.
If you your ohmic probe input is not responding the way
described above, check the "Ohmic Probing" (page 64)
4.12.7 Testing Torch Breakaway
Your Tormach 1300PL is equipped with torch breakaway
detection to stop motion in the event that a tip-up during
cutting causes a collision with the torch. A proximity sensor is
located in the touch mounting base to detect when the
mounting clamp has been knocked off.
1. Make sure that the machine is on and PathPilot is
running.
2. Switch to the Status tab on your PathPilot controller and
locate the BREAKAWAY SWITCH led. It should be off
initially.
3. Pull the torch clamp away from the base. You should see
the LED light up when the torch clamp is removed and
extinguish when it is replaced.
4.13 CALIBRATE INITIAL HEIGHT SENSING
4.13.1 Set Ohmic Probing Sensitivity
The ohmic probing system on the 1300PL relies on a calibrated
resistance value between the torch cap and the workpiece. If
you do not calibrate your ohmic probe, you may find that it is
triggered by water on the work piece or inside the torch cap.
