the mixer. After a short delay the pilot burner will extinguish. Open just a little the oxygen
valve of the mixer.

Do not use the pilot burner for longer than 15 seconds at a time. If you
need it longer than that, wait 2 minutes before the following use, otherwise the
burner heats up too much.
12. Keep the
push-button still pressed down. Adjust the flame while burning in the
pipe by adding first propane and then oxygen, until the flame is alright.

The F-200 machine is provided with a timer, which gives the operator
30 seconds’ time to adjust the flame. If this time is exceeded, the valves will
close and the adjustment procedure will have to be repeated if no satisfactory
flame is obtained. If the pipe starts getting red hot before a satisfactory flame is
obtained, drive the frame back into rear position and wait until the pipe cools off
or replace it with another pipe.

button, the flame will extinguish. Close the service door of the
burner.
14. Start the machine and press the heating stop push-button
, the burner arm will
retract from the pipe and turn to its lower position.
15. The heating time is adjustable from 0-200 seconds. Adjust the heating time by
means of the heating time regulator
. The heating time is determined either just by
ocular estimation on account of the color of the pipe or else with the help of a infrared
thermometer (optional equipment). The heating can be interrupted by pressing the
heating stop button
when the pipe has reached the proper temperature.
