3. Instruction for Use
3.1 The whole equipment should be placed on a stable and dry plane to operate.
3.2 Before operation make sure the following things:
The power supply is the specified according to the butt fusion machine
Power line is not broken or worn
The blades of planning tool are sharp
All instruments are normal
All necessary parts and tools are available
The machine is in good conditions
3.3 Place appropriate inserts according to outside diameter of pipe /fitting
3.4 Welding procedure
3.4.1. Before welding, firstly, check if there are scratches or fissures on the surface of
pipes/fittings. If the depth of scratches or fissures exceeds 10% of the wall thickness, remove
the scratches or fissures.
3.4.2 Clean the inside and outside surface of pipe end to be welded.
3.4.3 Place the pipes/fittings and keep the elongated length of pipes/fittings ends to be welded
be equal (as short as possible). Another end of pipe should be supported by rollers to reduce
friction. Fasten the screws of clamps to fix the pipes/fittings.
3.4.4 Place the planning tool, switch it on and close the pipes/fittings ends by operating two
driver rods against the planning tool until continuous and homogenous shavings appear from
both sides. Separate the frame, switch off the planning tool and remove it. The shavings
thickness should be within 0.2
～
0.5 mm and it can be adjusted by adjusting the height of the
planning tool blades.
3.4.5 Close the pipes/fitting ends and check the alignment. The misalignment should not
exceed 10% of the wall thickness, and it could be improved by loosening or tightening the
screws of clamps. The gap between two pipe ends should not exceed 10% of wall thickness;
otherwise the pipes/fittings should be planed again.
3.4.6 Clear the dust and slit on heating plate (Don’t scratch PTFE layer on the surface of
heating plate).
3.4.7 Put the heating plate into frame after it have got the required temperature. Raise the
pressure up to specified by acting on the handle till the bead reach required height.
3.4.8 Reduce the pressure to a value which is enough to keep both sides touching with
heating plate for specified time.
3.4.9 When the time is over separate the frame and remove the heating plate, join the two
sides as quickly as possible.
