18. Move the tractor as necessary until the torch consumables are centered on the edge of the
workpiece, as shown.
Start to cut
1. Set the power to ON (I) for the track burner and for the plasma power supply.
2. Use the bevel compensation cut charts to find the following values for the bevel cut:
Adjust the pierce delay setting on the tractor to use the correct pierce delay value from the

cut chart. Use the timer control knob or equivalent control on your tractor.
Adjust the speed of the tractor to use the correct cut speed value from the cut chart. Use

the speed control knob or equivalent control on your tractor.
Adjust the plasma power supply to use the correct current (A) value from the cut chart. Use

the amperage control knob on the front of the plasma power supply.
3. You are now ready to make the bevel cut. Can the track burner control both the tractor and the
plasma torch?
If yes, start the tractor to start both the plasma arc and the tractor motion.

If no, start the tractor and the plasma torch at the same time. Use a remote start pendant to

start the plasma arc.
4. Make sure that the plasma arc transfers to the workpiece and that the tractor starts the forward
motion.
5. At the end of the cut, stop the tractor as soon as the plasma arc extinguishes, if the tractor does
not stop automatically.
