thumbwheel switch on the power supply (arc current) according to the charts.
3. When using a machine torch system with a THC, set the torch-to-work distance and set the arc voltage and
current on the remote control according to the charts.
4. Select the proper travel speed from the charts and adjust the cutting machine speed accordingly.
5. Adjust the MACHINE DELAY on the power supply to meet the recommended motion delay time in the charts.

your cut.
Operating Tips
Changing Consumable Parts
The consumable parts in the torch need to be monitored periodically for signs of wear. A good rule of thumb is to
check the parts after every 150 starts.
To remove the consumables:
1. Unscrew the retaining cap. First bring the torch to the edge of the machine, with the lifter raised to its highest
point. Positioning the torch in this way prevents the danger of dropping the consumables into the water in the
water table.
2. Remove the retaining cap.
3. Check the shield for external signs of wear. The shield should be clean and clear of metal debris. The gas
holes along the edge of the shield should not be blocked with debris. The center hole should not have any
nicks or gouges, and should show no signs of arcing activity.
WARNING
Always unplug the power supply before inspecting or changing the torch parts.
