Part of the QTRW66 Series, it features a 45-degree bend angle and a fully insulated, rugged construction built for continuous robotic welding duty. The inner tube is machined from a brass and copper duplex extruded construction that supports both electrical conductivity and internal water flow. Cold water circulates from the torch body through the conductor tube to the front nozzle area, drawing heat away from the gas diffuser, contact tip, and nozzle during operation. Licensed welding technicians and robotic welding integrators install this part during torch maintenance or system setup.\u003c\/p\u003e\u003cp\u003eThis conductor tube is rated for water-cooled robotic torch applications up to 600 amps. The QTRW66 Series design fits torch bodies that use two stainless steel alignment pins for positive tube location. It accepts the standard QTRW54-16 gas diffuser, which is compatible with threaded 16RS, 16RZ, and 16S series contact tips. This part is suited for heavy-cycle robotic welding cells in industrial and manufacturing environments where consistent thermal management and torch repeatability are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWater-cooled design rated up to 600 amps for high-duty-cycle robotic welding\u003c\/li\u003e\n\u003cli\u003e45-degree conductor tube angle for QTRW66 Series torch bodies\u003c\/li\u003e\n\u003cli\u003eBrass and copper duplex extruded inner tube provides electrical conductivity and internal water passages\u003c\/li\u003e\n\u003cli\u003eStainless steel outer jacket insulated from inner tube assembly with a Teflon sleeve for dielectric protection\u003c\/li\u003e\n\u003cli\u003e3\/4-inch O.D. stainless steel seamless outer tube brazed between copper nozzle housing and brass crimp ring for structural integrity\u003c\/li\u003e\n\u003cli\u003eTwo stainless steel alignment pins positively locate the tube in the torch body; stainless steel locking screw secures it in place\u003c\/li\u003e\n\u003cli\u003eThermally conductive insulator in nozzle housing draws heat out of the nozzle area during operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with QTRW66 Series robotic water-cooled torch bodies.

Before removing or installing the conductor tube, shut off the welding power source and depressurize and drain the water-cooling circuit to prevent burns or water damage. Verify alignment pin seating and confirm the locking screw is fully engaged before resuming operation. Do not operate the torch without active water cooling connected, as the conductor tube relies on water flow for thermal management.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 600 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBend Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Type\u003c\/strong\u003e: Water-cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Tube O.D.\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Tube Material\u003c\/strong\u003e: Stainless steel seamless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Tube Material\u003c\/strong\u003e: Brass and copper duplex extrusion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Diffuser Compatibility\u003c\/strong\u003e: QTRW54-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Tip Thread Compatibility\u003c\/strong\u003e: 16RS, 16RZ, 16S series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246162492\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TWECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1663-1702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51346126012722,"sku":"1663-1702","price":1575.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546160.jpg?v=1782071475","url":"https:\/\/voomisupply.com\/products\/tweco-1663-1702-robotic-conductor-tube-600a-qtrw66","provider":"Voomi Supply","version":"1.0","type":"link"}
