Product Details

***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 PVC, HDPE, EVA, PP and so on.

The control of this series of welding machine adopts PID automatic thermostatic control with high control accuracy and low temperature fluctuation; speed control adopts PWM automatic voltage and speed regulation circuit, driven by DC servo motor, with great output torque and the operating is stable. It can maintain a constant speed on the condition of creeping, vertical creeping and variable road load. Also this series of welding machine is stable in performance despite of external temperature and voltage variation.

This series of welding machine is excellent in performance and easy for operating, with high welding speed and good work quality. It is extensively used in engineering projects such as expressways, tunnels, reservoirs, waterproof of construction and so on

***Main Components***

***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 rollers and engages the two fused base materials.

***Operating regulations***

1.)Use with grounded 3-cord mains cable and 3-hole socker with capacity not less than 10A (socket corresponds with welder plug,phase L connected to live wire ,N to zero line ,phase to grounded protection liner),confirm that external lines have been well connected .Check that power is on off state and regulate temperature control potentiometer and speed control potentiometer to 0 position ,press lever handle down to disengage pressure roller ,then insert the plug .

2). Turn on the power and select certain temperature and speed, take several narrow materials for try welding. Temperature selection may be different for the same material at different ambient temperature and material thickness. To determine the best welding effect, adjust the speed to approximately 2m/min, and then fine increase it from low to high temperature (approximately 250℃-350℃).

4). Flatly and straightly trim the weld edges and frontage faced, with lower left and upper right overlapped. The overlap width is 100mm.

5). After temperature and speed have been determined, insert material to be welded between the two pressure rollers, make machine body parallel with edges of base materials and engage press lever handle for proper motion. Generally, only observation of deviation between welding mark and base materials is needed for operator, and timely make correction on small degree.

6). When welding will be ended, timely press lever handle to disengage upper and lower pressure roller to prevent rubber wheel damage for long duration.

7). Excessive temperature high and low may occur because of thermal inertia. On this condition, temperature deviation may be compensated by speed regulation on a small degree.
