Butt Fusion Procedure
3 - 3
Determine Fusion Pressure
The theoretical fusion pressure can be determined using the
fusion pressure calculator that is supplied with the machine or by
using the McCalc® app is available for iOS, Android, Windows
Phone and PC devices.
Always add drag pressure to the theoretical fusion pressure.
Gauge (Fusing) Pressure = Theoretical Fusing Pr Drag
Pressure
Drag pressure should be determined using the following
procedure:
After facing the pipe, move the carriage so that the pipe
ends are approximately 2" apart.
Shift the carriage control valve to the closed position.
Gradually increase the pressure by actuating the pump lever.
Record the pressure at which the carriage begins to move as
drag pressure.
Take the theoretical fusion pressure, determined from the
calculator, then add the actual measured drag pressure. This
will be the gauge pressure to be used for the fusion.

Jaw Configuration
The DynaMc HP 4 jaw machines can be configured to a 2
movable jaw/2 fixed jaw configuration or a 3 movable jaw/1
fixed jaw configuration. This will allow work in close proximity to
ells and tees without the removal of the outer jaw.
To change to the 3 movable/1 fixed jaw configuration:
Unscrew the knobs on the jaw braces and remove the braces.
Align the brace between the inner movable jaw and the inner
fixed jaw. The carriage may have to be moved to align the brace.
Attach the brace with the knobs to secure them in place.
To change to the 2 movable/2 fixed jaw configuration:
Unscrew the knobs on the jaw braces and remove the braces.
Align the brace between the inner fixed jaw and the outer fixed
jaw. The carriage may have to be moved to align the brace. A
block of wood should be used on both sides across the guide rods
to push the inner fixed with the movable jaws to align with the
outer fixed jaw. Attach the brace with the knobs to secure them in
place.
