geomembrane wedge welding machine
Welding machine introduction>>>
Geo-membrane welding machine is our new developed products, which can weld geo-membrane of various
thickness and are applicable for welding of all thermal-fused material such as LDPE, PVC, HDPE, EVA, PP
and so on.
1. Technical parameters>>>
Voltage (V): 220V
Frequency (Hz): 50Hz
Power (P): 800W
Welding speed (V): 0.8-6m/min
Heating temperature (T): 0-450°C
Thickness of material to be welded: 0.2mm-2.0mm
Overlap width: 100mm
Welding width: 12.5mm×2, interior cavity 12mm
Seam strength: ≥85% base material (tensile resistant in shear direction), complete machine
Dimensions: L32 x W15cm x H22cm
Net Weight: 4.8kg
Gross Weight: 8.5kg
Insulation class: class II
.
2. Main Components>>>
3.Operation principle>>>
Motor drives upper and lower pressure rollers to rotate through reduction gearbox and chain. Slide carriages
drive the hot wedge and insert it between the two base materials, at the same time lever presses pressure rollersand engages the two fused base materials.

4. Operating regulations>>>
As welding quality is direct related to speed and temperature setting during operating, so welding machine must be
specified personnel operated to reach excellent quality and high efficiency.

5. Replacement of components>>>
1). Replacement of hot wedge assembly
Remove the front end covering, remove the 4-M4 screws and tapping screw, remove a half housing, release 4-M3
screws, remove the 2-M5 screws that connect heating support and slide carriage, remove hot wedge and replace
with a new one, and reassemble the complete machine (shown as fig.6). Note: conform to color on wiring.
(Refer to fig.10 and text information)

3). Replacement of motor
Remove all screws on housing, remove front end covering to remove housing, remove the 4-M5 installation screws on
the support, remove the main chain guard and separate the upper and lower support. Remove the covering on the
bottom of upper support and weld connection between motor and fuse holder, screw off the 2-M5 installation screws of
the motor, take off motor and replace a new one. Weld back the removed wires and reassemble on the opposite sequence
(Note: keep upper and lower pressure roller is parallel during assembling.).

There may be sand or small stones on chain and gear |
Remove sand or small stones |
7. Maintenance>>>
The complete machine should be cleaned, greased and placed in a dry place if it is not used. For PVC welding, the adhesions
on hot wedge should be cleaned off if it is not used longer than 4 hours to prevent wedge corrosion and service life being
shortened.
