Workshop manually operated butt welding machine suitable for PE, PP, PVDF and other thermoplastics pipes and fittings.
The pivoting clamps allow the machine to fabricate segmented bends with different radii.
The machine being capsizable into the frame, reduces the overall dimensions for transport and stocking when not in use.
The machine is supplied complete with:
bullet Basic machine including the frame
bullet Revolving electric facing tool with drill or reduction gear motor
bullet Revolving PTFE coated heating mirror
bullet Two pivoting clamps dia. 315 mm
bullet Two back supports
bullet Light weight alloy reducing rings for the pivoting clamps (4 inserts per set)
 

Basic machine
Description

The basic machine is composed of:
bullet A fixed trolley on which are mounted the lever, one main clamp and a back support
bullet A movable trolley on which are mounted one main clamp and a back support
bullet On blocking handwheel
 

Maintenance

 
It is strongly suggested to always keep the machine clean, with particular care of the bolts.
Keep attention while inserting the electric facing tool and the PTFE coated heating mirror, avoiding damage to the machine's slide bars.
 

Facing Tool

 
Description

The electric facing tool is composed of:
bullet The facing tool body
bullet Two pulleys where are mounted the blades
bullet A drill engine
bullet A starting push button
bullet A connecting box
 

Heating mirror

Description

The heating mirror is composed of:

bullet The heating mirror coated with green colour PTFE complete with thermometer and connecting box
bullet The electronic thermostat located on the connecting box.
 

Important

The heating mirror's temperature during the working operations is always above 200°C, therefore keep attention and utilize if possible protective gloves in order to avoid burns.
 

b.Welding
b.1 Machine set up

  1. Connect the machine to the power supply
  2. By acting on the push buttons of the thermostat located on the bottom part of the heating mirror, set up the temperature needed for the welding.

 
In order to select the necessary temperature, operate the push buttons, increasing or reducing the value according to the type of material and wall thickness of the pipe to be weld ,the most common values are the following:
bullet HDPE210 °C +/- 10
bullet PP 200 °C +/- 10
bullet PVDF 230 °C +/- 10
The above values are also depending on pipe wall thickness, therefore for accurate temperature setting up we suggest to check the enclosed graphic.
In order to avoid mistakes on temperature selection, the maximum possible setting value is 299 °C.
 

Important !!!
The heating mirror's temperature during working operations is always above 200°C, therefore keep attention and utilize if possible protective gloves in order to avoid burns.
Before proceeding to the first weld, wait until the lights have been switched on and off three times, this allows the stabilization of the temperature on the heating mirror surface.
 
  1. Take from the tool box the reductions needed, and fix them by using the proper screw into the main clamp and the derivation clamp. (the diameter is engraved into the reductions)
  2. Insert the pipes to be welded into the clamps, taking care to leave enough space for the facing unit insertion.
  3. Start with the facing operation
 

b.2 Facing operation

1.  Insert the facing tool between the two pieces to be welded, and start the engine by means of pushing the push button.
2.  Approach the two pipe ends by means of acting on the lever, and apply a small pressure in order to avoid the block of the facing tool (engine might burn out). When the shavings are regular and homogeneous, take away the two pipe ends, then shut off the engine and rotate back the facing tool.
3.  Approach the two pipes ends and verify the alignment – adjust if needed.
     

In order to realign the pipes :

a.     Untighten the screws A
b.     Adjust the clamp on horizontal way
c.     Tighten the screws A
Remember to not touch the pipe ends after the facing operation.
 

b.3 Welding

1.   Insert the heating mirror between the two pipe ends, taking care that the thermostat has been set up to the correct welding temperature and the surfaces of the heating mirror is the one set up
2.   Approach the two pipe ends towards the heating mirror by means of acting on the lever and applying the correct welding pressure as per attached Welding Tables.
Wait for the bead formation, then reduce the pressure, keeping the two pipe ends in contact with the mirror.
3.   One heating time has elapsed, take away the two pipe ends from the mirror by means of acting quickly the lever in order to open the trolley, rotate back the heating mirror and by means of acting quickly the lever in order to close the trolley, applying the correct welding pressure as per the welding table.
The value of the pressure can be read on the pressure index and while achieved such value, block the trolleys by means of tightening the handwheel.
4.   Following correct cooling time, keep strongly the lever and untighten the handwheel - reduce to zero the pressure.
5.   Take away the welded piece
6.   Check the welding
7.   Important! never try to cool down the welding and in case of strong wind, operate in protected area
In case of rain or ambient temperature less than -5 °C or higher than 40 °C, the welding operation cannot be done, as these weather conditions affect the good result of the welding.
 

c. Fabrication of segmented bends

In case of utilizing the machine for the fabrication of segmented bends with different radii, the main clamps should be rotated by means of loosening the below screws, and rotating according to the angle index. (see figure).

As far as concerns the end float, vertically there's not any regulation due to the fact that there will be a maximum difference of 0,1 - 0,2 mm. Sideways by means of adjusting the cross slide the two pipe ends should be aligned and the pipe should be centred with the facing tool.
 

d. Welding of injection moulded fittings

In case of utilizing the machine for the welding of injection moulded fittings, the back supports should be adjusted by moving and/or rotating them after loosening the blocking hand wheels.
