CUTTING CAPABILITY

The PYTHON is rated at 80 amps, at 60% duty cycle on a 10 minute basis or 60 amps, at 100% duty cycle. If the duty cycle is exceeded, a thermal protector will shut off the output of the machine until it cools to the normal oper- ating temperature.

Figure B.1 shows the cut capacity of the PYTHON when cutting mild steel. The graph plots cut thickness vs. torch travel speed with a torch standoff of 0.15". Example: 0.5” material may be cut at a setting of 55 amps at an approximate speed of 25 IPM or at a setting of 80 amps at an approximate speed of 35 IPM.

CONSUMABLE LIFE

The expected life for the PYTHON's electrode under normal operating conditions is approximately 160 starts/cuts. An erosion of .060" is typical for end of electrode life, however, the electrode life may last longer. A green and erratic arc will indicate definite electrode failure and the electrode should be replaced immediately.

It is recommended that consumables be replaced in complete sets. (Example: Electrode and Nozzle). This will maximize the performance of the PYTHON system.
