China HDPE Wedge Welder Plastic Welders

Geo-membrane Overlap Hot Wedge Welder
User's Guide for HSD-300
General
Geo-membrane welding machine is of of our portable welding 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.
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.

2. Precautions
1). For correct operation, please carefully read this instruction.
2). Use with grounded 3-cords mains cable and socket (socket with 10A capacity. On the corresponding welder, phase L connected to live wire, N to zero line, phase to grounded protection line), plug will not be modified without prior permission.
3). For good welding quality, please assign specified personnel for operation.
4). Pressure roller will not engage on free running.
5). Do not operate when it is exposed to water to prevent inferior quality.
6). The machine has been regulated before leaving factory. Please do not adjust it at will.
7). Circuit board in control box is electrified. Do not remove it without prior notice to authorized personnel.
8). Preheat for 30 minutes before start up if machine has been long unused or exposed to moisture.
9). Modifications may be made for continuous improvement, without prior notice.

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 rollers and engages the two fused base materials .
