Part of the QTRW66 Series, it features a 180-degree configuration and a fully insulated, rugged construction built to handle the demands of automated welding environments. The inner tube is machined from a brass and copper duplex extruded construction that provides strong electrical conductivity while maintaining dedicated water passages. A stainless steel outer jacket, insulated from the inner tube by a teflon sleeve, gives the assembly excellent dielectric properties. Licensed welding technicians and robotic welding integrators install this component as part of a complete water-cooled torch system.\u003c\/p\u003e\u003cp\u003eThis conductor tube is suited for robotic and automated MIG welding cells operating at high amperages where air-cooled torches are insufficient. The water-cooled design allows cold water to flow from the torch body through the conductor tube, circulating around the nozzle area to draw heat away from the gas diffuser, contact tip, and nozzle. The outer jacket incorporates a nozzle housing with a thermally conductive insulator that actively pulls heat out of the nozzle assembly. It accepts a standard QTRW54-16 Gas Diffuser and is compatible with threaded 16RS, 16RZ, and 16S series contact tips, as stated in manufacturer documentation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWater-cooled design rated up to 600 amps for sustained high-amperage robotic welding\u003c\/li\u003e\n\u003cli\u003e180-degree conductor tube geometry for QTRW66 Series torch configurations\u003c\/li\u003e\n\u003cli\u003eBrass and copper duplex extruded inner tube for high electrical conductivity and integrated water passages\u003c\/li\u003e\n\u003cli\u003eStainless steel outer jacket insulated from inner tube assembly via teflon sleeve for dielectric protection\u003c\/li\u003e\n\u003cli\u003eTwo stainless steel alignment pins positively locate the conductor tube in the torch body; stainless steel locking screw secures it in place\u003c\/li\u003e\n\u003cli\u003eBrazed tapered front end on inner tube creates a solid heat transfer path between inner tube and jacket assembly\u003c\/li\u003e\n\u003cli\u003eAccepts standard QTRW54-16 Gas Diffuser and threaded 16RS, 16RZ, and 16S series contact tips\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the QTRW66 Series robotic water-cooled torch body.

Before servicing, shut off water supply to the torch cooling circuit and disconnect welding power at the source. The conductor tube is seated using the two alignment pins and drawn into position with the stainless steel locking screw — do not overtighten. Verify water flow through the circuit is restored and free of leaks before returning the torch to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 600 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling Method\u003c\/strong\u003e: Water-cooled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QTRW66\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\u003eOuter Jacket Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Sleeve Material\u003c\/strong\u003e: Teflon\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: 1.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 608246162447\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: 1663-1704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TWECO","offers":[{"title":"Default Title","offer_id":51344153870642,"sku":"1663-1704","price":1526.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546163.jpg?v=1782030502","url":"https:\/\/voomisupply.com\/products\/tweco-1663-1704-robotic-conductor-tube-600a-qtrw66","provider":"Voomi Supply","version":"1.0","type":"link"}
