3. OPERATING INSTRUCTIONS TECHSPAN Automatic wedge welding machine type common Please read the operating instructions carefully before use and keep for further reference APPLICATION The TECHSPAN commonis an automatic hot wedge welding machine for overlap welding manufacturing of films and geomembrane liners in tunnels as well as in earthwork and civil engineering e Overlap max 140mm e Type of seam Welding seams are produced in accordance with DVS 2225 part I Other dimensions of seams are possible on request e Type of wedge In standard version the TECHSPAN Common is supplied with a copper wedge for welding of PE and PP On request we can supply a ceramic wedge for welding all different kind of materials on sy Niederhatterrolle Obere Dichtungsbahn ey Obere Antriebs Andrdeckrolle j A Fuhrungsrolie hinter Fuhrungsrote vorne lt lt Pia Kei 4 OP Pe 0G SECURITY WARNING Danger Unplug the tool before opening it as live components and connections are exposed Danger of fire and explosion in case of incorrect use of the hot wedge welder especially near combustible materials and or explosive gases Danger of burns Do not touch the hot wedge when hot allow the tool to cool down Connect the tool to a socket outlet with protective earth conductor Any interruption of the protective earth conductor within or outside the tool is dangerous Use only
4. m without test channel is guaranteed by the swivel head This allows T joints to be welded without problems During the welding process the pressure adjusts itself linearly to the change in material thickness of the geomembrane liner Cross sectional diagram of an overlap weld Zeige aay ZA eee S1 LC Reduction of seam thickness S1 S2 S1 thickness of the upper and lower membrane S2 thickness of welded seam L1 welded section 1 L2 welded section 2 LC test channel e Drive double upper and lower steplessly adjustable and electronically controlled The control system is designed in such a way that the adjusted speed remains constant independently of the load WELDING PARAMETERS Welding pressure engage and position the welding tool onto the material to be welded Pull the toggle lever without engaging the hot wedge By rotating the adjustment screw the drive pressure rollers will lightly touch the material to be welded in this way you will define the POINT ZERO 0 N of pressure Unhook the toggle lever for the locking mechanism and open the toggle lever Set the desired pressure by rotating the adjustment screw to every single step of rotation you will set 90N of pressure on seam Lock than the desired pressure with the locking screw Warning If the maximum welding pressure 1400 N is exceeded mechanicals damage may occur Welding temperature set the welding temperature with the UP DOWN key
5. s of the temperature controller positioned on the left of the front panel The switch ON OFF of the heating is positioned under this same controller Start the welding only when the actual temperature correspond to the set value An alarm signal AL will be shown in the lower right corner of the display if the actual temperature is too low than the set value in this case the motor can not be started or if in function will stop automatically Welding speed set the welding speed by the potentiometer on the front panel the motor is switched on and off by the switch near the potentiometer The speed shown on the display corresponds to the actual welding speed WELDING Welding preparation Laying of material Width of overlap from 80 to 140 mm Make sure that the surfaces of geomembrane liners above and below are cleaned as well as between the overlap Mains supply at least 3K W generator supplied with an RCCB Residual Current Circuit Breaker Operating conditions Connect the tool to the mains Start the tool with the main switch level Welding procedure e Adjust the welding parameters see page no 4 e Wait until the wedge has reached the adjusted temperature e Guide and position the welding machine into the over lapped geomembrane liner or film e Switch on the drive motor with the foreseen switch e Engage the hot wedge into the over lapped geomembrane liner or film e Push down the toggle lever to obtain the blockade
6. sing keeping blocked the correspondent screw of guide roller e Assemble chain guard lower part e Unhook the pressure lever and move the wedge from the welding position e Check that all the screws are well tight and proceed with a weld test MAINTENANCE Clean the hot wedge with a wire brush at the end of working day Clean the drive pressure rollers with a wire brush As required treat the chain with a suitable spray After use always check that the mains cable and plug are not damaged SERVICE AND REPAIR The welding machine should be checked by an authorised service centre approx every 1000 hours of running time Inspections and repairs have to be executed exclusively by TECHSPAN authorised service centres GUARANTEE AND LIABILITY For TECHSPAN guarantee and liability see our the general and sales conditions TECHSPAN rejects any guarantee claims for tools which are not in original condition Modifications of the tool will void any guarantee claims Technical data are subject to change without prior notice
