SM-QRTORCH INSTALLATION AND DISASSEMBLY
23. Plug or wire the other end into the proper pin locations on
the robot. Refer to the manufacturer recommendations
and installation instructions.
24. If the torch being installed is a water-cooled QRW or QRWA
series, a water supply providing not less than ¾ gallons/
minute (2.84 liters/minute) water flow must be used
during operation. The water supply should be installed
to run when the power source is turned “on” if possible
to avoid any damage to the torch and cable assembly.
CAUTION
Operating a water-cooled torch and cable
assembly without water or restricted flow will
result in damage to the cable assembly.
25. The torch and cable assembly is furnished with a purge
hose that can be used to supply inert gas and or anti-
spatter through the torch block and conductor tube
assembly. To use this purge hose, remove the plastic plug
and connect accordingly.
26. The torch is now ready to place into operation. Be sure to
check the TCP and single step the robot through the robot
program to ensure that the conductor tube positioning is
correct.
