Operation - Semi-Auto Fusion
Heat Pipe
Follow the pipe manufacturer's or joining standard's suggested
heating procedure.
IMPORTANT:
A modified shift sequence may be required in certain
situations.
Shift the pressure selector control to the fusing position and move
carriage to the left to bring pipe ends in contact with the heater.
Ensure proper initial bead-up, move pressure selector control to
middle (heating) position. If heating pressure is not required by
pipe manufacturer or joining standard, or opposing forces are not
great enough to move the carriage away from the heater, shift the
carriage directional control to neutral after the carriage pressure
drops to drag pressure.
IMPORTANT:
Always shift into the heating mode
before
returning
carriage directional control to neutral.

Fusing the Pipe
NOTICE:
Failure to follow the pipe manufacturer's heating time,
pressures and cooling time may result in a bad joint.
After following the heating procedure, verify carriage directional
control is in neutral and move pressure selector control down to fusing
position.
Open the carriage just enough to remove the heater.
Self Retracting Heater:
Open the carriage completely so that the
heater retracts.
Quickly remove the heater.
Quickly inspect pipe ends for appropriate melt.
When heater is clear of the jaws, quickly close the carriage to bring
the pipe ends together. Ensure the appropriate maximum open/close
time is not exceeded.
Allow joint to cool under pressure according to pipe manufacturer’s
or appropriate joining standard's recommendations.
