Geomembrane Overlap Wedge Welder
Working Principle Electric machine carried with above and below pressure wheel and turn it through
speed-slow box and chain steel, and heating the bracket up and turn thermal wedge
to plug in between the two main materials, meantime let the pressure bracket press
Notice: In order to obtain the excellent quality and high efficiency, it should be
manipulated by professional people since the welding quality of the machine has
direct relationship with the enactment of speed and temperature.
1. The user must choose to the three holes receptacle with earthing and confirm
the good connection of exterior wire. Pick the pressure handle up to separate
the up and down iron wheels and then plug the power supply on.
2. Switch power supply on, and choose suitable temperature (Temperature
adjusting diagram – literature) and speed. Then pick some narrow material to
weld for a try and make sure the best effect. Owing to the difference between
the environmental temperature and the thickness of material, the welding
temperature of the same material could be different. We can choose to a
referenced speed (about 1.5m/min) when select the temperature. And then
slowly adjust the temperature from low to high, about from 250℃ to 400℃
(482 to 752℉)
3. The estimation of the welding temperature: it can be directly watched the
transparence PE material .If the welding mark is lever-off with transparence glass
status, it showed that the temperature and the speed is suitable; if the welding
mark is seriously broken up, it showed that the temperature is too high or the
speed is too low; If the welding mark is not transparence with white status, it
showed that the temperature is on the slow side or the speed is on the fast
side .And to the non-transparence material ,it also can be tested by resistance
pull after the whole party is cooled down.
4. Mending the edge of the welding material smooth .The surface face to the front
side, and overlap to left down and right up .The width of pulled up is 120mm.
5. Plug the welding material between the two iron wheels to make the parallel
between the body of the machine and the edge of mother material, and it can
weld itself after confirmed the temperature and the speed. Usually the operator
just watch the warp between the welding mark and the edge of the mother
material and timely rectify it within a small scope .At the end of material welding,
pick up the handle to separate the up and down iron wheels.
6. Owing to the thermal inertial, it can adjust the temperature within small scope
to offset the discrepancy in temperature if it comes too high or too low in the
process of welding.
7. In the process of welding, it can adjust through the two interior hexangular
screws on the swaying head if the welding mark is not equality in two outside.
(Just the corresponding screw in the upside of intensive welding deep or in the
upside of loosen welding mark shadow)
8. Welded material crossed with another material in the shape of “T”. The ways of
welding is as the diagram below. Cut the crossing head sticking to the thermal
wedge off 12cm inclined.
The adjustment of the Pressure Wheel
According to the various thickness of material, it can be adjusted the magnitude of
pressure by switching the modulated screw. It will increase by clockwise, and it
decrease by anticlockwise.
