New Tweco RT Robotic Torches Offer Industry Best Tool Center Point, Modular Design

November 11, 2019

Annapolis Junction, Md. – Tweco, an ESAB brand, will launch its new Tweco® RT series of robotic MIG torches at FABTECH 2019, November 11-14, at McCormick Place in Chicago. The new generation of robotic MIG torches features a massive brass outer tube that provides the most reliable TCP in the industry. As a result, they can withstand a collision and still maintain tool center point (TCP), as well as eliminate TCP drift due to repeated heating and cooling cycles.


“With RT torches, the weld bead stays exactly where you want it — in the center of the joint — without the need to compensate with weaves or slower travel speeds,” says Alexander Fischer, Global Robotic Product Manager, ESAB.


Tweco RT torches for standard robotic welding applications are available for ABB, Fanuc, KUKA, Motoman/Yaskawa and other robotic systems in the following packages:

  • Standard wrist with external cable
  • Helix hollow wrist (± 270o rotation)
  • Infiniturn hollow wrist with endless rotation
  • Gas- and water-cooled models
  • Multiple conductor tube angles: 180 o, 22 o, 22Lo, 45 o and 45Lo
  • Push-Pull torch with easy wire feeder synchronization

Designed for all robot types and models, the torch contains a built-in blow out port for cooling and/or cleaning of the conductor tube, long-life consumables, torch body and spare parts and quick-change torch system. Tweco RT torches feature a modular design. They use the same conductor tube for standard and hollow wrist robots, plus air- and water-cooled torches of the same torch model use the same cable assembly and spare parts, reducing inventory. RT Torches enable simple installation and exchange of the cable assembly, and all components remain precisely aligned during change-over to maintain a constant TCP.


For use in conjunction with robotic torches, the Tweco BRG-2 Torch Cleaning Station removes spatter with a rotating reamer and sprays anti-spatter fluid in an enclosed chamber, eliminating the shielding gas inconsistencies that can promote weld flaws. It also promotes consistent arc starts and reduces spatter by cutting the wire end to a defined length.
