INSTALLATION AND DISASSEMBLY

16. Tighten the set screw on the Tweco

, Panasonic

, and

or Lincoln

rear connector plug. For Miller

style rear

connector plug, re-install the threaded connector plug

nipple. This connection should be wrench tight.

17. Re-insert the factory-supplied 5/32” T-handle allen

wrench into the hole for the “Conduit Set Screw” on the

front handle cap and rotate the set screw clockwise. The

set screw should be hand tight. Refer to Figure 3-5.

18. Trim the conduit extending from the front of the conductor

tube assembly by following the steps below:

Method “A” – Using a tape measure or scale, mark and

cut the conduit to the cut length noted in the

table below. Refer to Figure 3-6 — Method

“A”.

Method “B” – The diffusers have a machined groove

around the outer diameter. Position the

diffuser as shown in Figure 3-6 — Method

“B” and mark and cut the conduit.

19. After trimming to length, remove any obstructions from the end of the conduit radius.

20. Re-install the diffuser, tip, and nozzle onto the conductor tube assembly.

21. Loosen the ﬁxture connection and insert the cartridge kit of the torch and conductor tube assembly into position. The

keystock located on the cartridge kit should be placed into the mating slot on the ﬁxture until the sleeve bottoms against

the ﬁxture plate. Re-tighten the connection to secure the assembly in place. Refer to Figure 3-7.

KEYSTOCK

rt # JB-00014

Figure 3-7: Locating Keystock

NOTE

For cable assemblies longer than 5ft. (1,52m), it

is recommended incorporating a spring-loaded

stabilizer bar/balancer to the robot work cell to

provide support to the center of the cable assembly.

This will eliminate both excessive drooping of the

cable assembly and any interference with the

ﬁxtures and tooling in the work area.

22. Install the rear connector plug into the feeder.

23. If the torch being installed is a water-cooled QFW 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.
