SM-QRTORCH INTRODUCTION AND DESCRIPTION
QRA Series Air-cooled Robotic Torch and Cable Assembly
The air-cooled QRA cable assembly uses QTR66 air-cooled conductor tubes. It has an air-cooled power cable rated at 600
amperes @ 60% duty cycle.
QRW Series Water-cooled Robotic Torch and Cable Assembly
The water-cooled QRW cable assembly uses QTRW63, QTRW64, or QTRW66 water-cooled conductor tubes. It is furnished
with a water-cooled power cable rated up to 600 amperes @ 100% duty cycle.
QRWA Series Water/ Air Robotic Torch and Cable Assembly
The QRWA cable assembly is a hybrid using QTRW63, QTRW64, or QTRW66 water-cooled conductor tubes but it utilizes an
air-cooled power cable assembly rated up to 600 amperes @ 80% duty cycle. If water flow is interrupted, amperage rating
is decreased. This provides a torch that has water-cooling of the front consumables while providing a trouble free rugged
air-cooled cable assembly.
QRAS, QRWS, and QRWAS Robotic Nozzle-sensing Torch Cable Assembly
This series of torch and cable assemblies incorporates the same power cables and are rated at the same amperage rating
as the series mentioned above. The only difference is the torch block and the use of the QTRW64-ST series conductor tube
assembly.
A wide variety of conductor tube and front-end consumables are also offered. Contact your local welding distributor and/or
Tweco
® Customer Service Department (1-800-426-1888) for assistance in choosing the correct conductor tube and consumables
for your welding application.
