Therefore the extraction is close to the weld pool, so the fumes coming from the welding process are extracted immediately. As a result the welder is exposed up to 95% less welding fumes. The quality of the welding process remains the same as with a welding torch without integrated ex- traction. The welding torch is delivered ‘ready to use’. It only has to be connected to a welding machine and extraction unit. The 8TE Extractor welding torch is available in a gas- and water-cooled version The welding torches in this manual have been build in compliance with: • EN 60974-7 Arc Welding Equipment Part 7: Torches • 2006/95/EC Low Voltage Directive • 2004/108/EC Electromagnetic Compatibility The welding torch is only to be used by experienced personnel. It is not allowed for untrained persons to install, handle or maintain our welding torches. Welding torches must be checked regularly in order to guaranty optimum life time expectancy. The user is fully responsible for possible defects arising out of misuse, inadequate maintenance, damage, poor repair, or modifications by other parties than the original manufacturer, or his authorised dealers. The welding torch is a component of a complete welding system. The torch will generate an electric arc when connected with the appropriate welding machine. Ensure that you read the welding machine’s instructions thoroughly before using our welding torches. The manufacturer reserves the right, whenever necessary and without prior notice, to amend these instructions as a result of clerical or printing errors, incorrect information, or the addition of improvements.www.translas.com 4 2. Safety ... WARNING PLEASE READ THESE SAFETY INSTRUCTIONS CAREFULLY Failure to observe these safety instructions can lead to serious injury and/or damage to the product. Only operators with relevant knowledge of arc welding should use this product. • The vibration of the welding torch is less than 2.5m/s². No special precautions are required related to vibrations. • Arc welding can injure eyes, burn skin and cause hearing damage. Therefore: - Use welding shield with filter complying with respectively the EN 175 and EN 379 standards - Wear proper protective clothing and ear protection - Make sure others are protected (e.g. curtains) from arc rays and flashing • Remove all combustible materials – including liquid and gaseous fuels, cloth, sawdust, wood, paints and solvents - from the work area or completely cover the materials with a protective non- flammable covering. Fire extinguishing equipment should be ready at hand for instant use. Pay attention to spatter/dross created during welding; sparks can cause fire several hours after welding has finished! • Work pieces must be completely cleaned so that no substances on the material, such as chlorinated solvents, can produce flammable or toxic vapours. • Do not weld containers that have held combustibles. • Always check cables before operating the machine. Defective cables may cause injury and/or fire. • Do not make temporary repairs. Repairs should be made by qualified personnel. • Do not pull cable assembly across sharp edges or expose to welding spatter or hot surface. • To prevent electric shock, isolate yourself by using proper protective clothing and insulating mats. DO NOT wear wet clothing! • Do not exceed power rating. Overload can lead to torch damage, destruction and/or injuries. • Turn off primary power before working on torch parts and/or replacing consumables. • Do not breathe fumes or gases from welding. Welding fumes are harmful; lead, cadmium, copper, zinc, mercury, stainless steel, galvanised steel and beryllium in particular. Therefore, use venti- lation or an extraction system to ensure that Maximum Admissible Concentration of harmful substances (MAC) level is not exceeded. • Use proper gas for the welding process (100% argon) and pressure reducing regulator. • Keep cylinders in an upright position. When not in use, keep cylinder valves closed. Keep cylinders away from heat, sparks or flame. • Follow the pressurised gas manufacturer’s operating instructions for mounting the regulator to the gas cylinder. www.translas.com 5 3.

Installation and connection ALSO FOLLOW OPERATING INSTRUCTIONS PROVIDED BY WELDING MACHINE MANUFACTURER WARNING! The TIG - power source must be deactivated! gas-cooled connection (standard) Read the instructions of your welding machine prior to use so as to be sure how to attach your welding torch. Connecting power/gas cable: Connect the power/gas cable to the appropriate connector on the welding machine and ensure a tight connection by properly affixing the coupling or fastening nut. Exception 1 Gas hose may have its own separate connector, which can be connected to welding machine by insert- ing gas nipple into the appropriate nipple receptor or by tightening connection nut onto the threaded counterpart on the welding machine. Exception 2 When torch is fitted with a gas valve (V-torch), connect separate gas hose to an external gas cylinder.www.translas.com 6 But before connecting it to the gas cylinder, open the gas bottle’s pressure regulator a few times briefly to flush away any dirt. After that, make the connection and tighten with a wrench. You can then set the desired pressure using the pressure regulator. The pressure will depend on the item to be welded and the gas cup size. Connecting switching cable Connect the welding torch plug into the appropriate socket on the welding machine, and check for a solid connection. If the switching cable does not have a plug, use the welding torch’s diagram (see next page) to mount a self brought plug. water-cooled connection (standard) Read the instructions of your welding machine prior to use so as to be sure how to attach your welding torch. Connecting power/water cable Connect the power/water cable to the appropriate connector on the welding machine and ensure a tight connection by properly affixing the coupling or fastening nut. Exception If an adapter is connected to the power/water cable, the red water outlet hose has to be connected to the welding machine according to the colour markings. Ensure that the connection is solid. Connecting (black) gas hose Connect gas hose to welding machine by inserting gas nipple into the appropriate nipple receptor or by tightening connection nut onto the threaded counterpart on the welding machine. Connecting (blue) water inlet hose Connect the blue water inlet hose by inserting gas nipple into the appropriate nipple receptor or by tightening connection nut onto the threaded counterpart on the welding machine according to the colour markings. Ensure that the connection is solid. Connecting switching cable Connect the welding torch plug into the appropriate socket on the welding machine, and check for a solid connection. If the switching cable does not have a plug, use the welding torch’s diagram (see next page) to mount a self brought plug.www.translas.com 7 Connecting Extraction hose Colour coding switching cable Owing to the large variety of welding machines and sockets, not every Translas TIG welding torch is fitted with a plug. When so, one can be fitted according to the diagram below, and according to the switching module functionality of the Translas TIG welding torch. start : start welding proces stop : stop welding proces up: increasing welding current or browsing machine program (depending on welding machine) down : reducing welding current or browsing machine program (depending on welding machine) potmeter : stepless up/down functionwww.translas.com 8 Single-button Translas TIG welding torches are normally supplied with a single button switch. In order to inter-operate with the new generation of welding machines, Translas TIG welding torches can be fitted with 2-, 3- or 4-button switches and/or an integrated potentiometer.

Operation Before operating torch check the following: - Is welding torch firmly connected to welding machine ? - Is welding torch firmly connected to fume suction unit ? - Is suction flow tested on the special 8TE Airflowmeter between 17 and 20m³/h ? (please note that suction flow needs to be tested withouit wear parts (ceramic/colletbody) - Is torch fitted with the correct parts for task ? - Are parameters set in welding machine ? - If water cooled: is circulating cooling unit working and is there sufficient coolant flow? - Has gas been tested to prevent contamination and / or to check gas pressure ? If all the above points have positive results, you can begin your welding job. TIG operation: AVOID CONTACT WITH HOT TORCH PARTS AND WORK PIECES - Please follow the instructions during the complete TIG operation. - Set the tig torch to the required start position. - Ignite the arc with the on/off button. (when torch is fitted with a gas valve (V-torch), open the gas valve and assure the gas coverage is available. After this, start the ignition by contacting work piece). - After ignition keep the torch at the start point until establish a weld pool. - Guide the torch constant during the whole seam length following the instructions. - Press the stop button at the end of the welding job. (when torch is fitted with a gas valve (V-torch), lift the torch until the arc tears off. Then close the gas valve). - Continue to hold torch at final position for a few seconds to allow molten pool to solidify without atmospheric disturbances (shielded by gas flow). The operator must wear protective clothing, and adequate ventilation must be available (see Section 2 for safety).Next >
