2.0 –INSTALLATION
STEP #1 - POSITIONING THE ROBOT
Position the robot with the wrist and top axis
as shown to properly complete the gun
installation.
STEP #2 - REMOVING OUTER COVER
Unthread (3) M4 SBHCS, using a 2.5 mm
Allen key.
Unthread (1) M3 SHCS, using a 2.5 mm
Allen key and pull apart both cover halves.
Insulating disc should remain in place,
located by dowel.
STEP #3 - INSTALLING GUN TO ROBOT
Locate assembly onto robot mounting face using dowel pin as a guide.
Insert M4x20 (x6) bolts through insulating disc and mounting flange into robot face. Thread bolts
clockwise using a 3 mm ball-nose Allen key (ball end) to 45 in.-lbs. (5 Nm).
Re-install Outer Cover in reverse order of instruction in STEP #2.

STEP #4 - CONNECTING LSR UNICABLE
Insert Unicable through mounting face of robot (cutaway of robot shown below).
Insert Unicable Connector into flange-cable connector. Ensure components are fully seated. Tregaskiss
Low Stress Robotic Unicable shown here (See Section 2.0 INSTALLATION)
Secure by tightening M6x20 SHCS, using 5 mm Allen key to 80 in.-lbs. (9 Nm).
Connect wire connectors (non polarity specific).
IMPORTANT: Leave slack loop around flange for articulation.
STEP #5 - INSTALLING NECK
Insert new neck over the liner and into connector housing until neck is fully seated.
Once fully seated and secured into place, see STEP #7 for liner trimming instructions.
NOTE: For best results, install the neck without the consumables so that the liner can pass through
easily.
Tighten Neck bolt clockwise with 5 mm Allen key to torque specifications (60 in.-lbs. or 7Nm).
IMPORTANT: Do not over-tighten bolt or damage may occur.

STEP #6 - INSTALLING POWER PIN TO THE LSR UNICABLE
Option #1 of 2: Power Pins
Install power pin onto the LSR Unicable.
NOTE: Power pins incorporate a taper to seat
and lock the pin to the rear handle block. Make
sure the power pin is tightened in the block with
a wrench to insure the pin is secure and will not
come loose.
oThread power pin into the adapter of
the LSR Unicable.
oTighten the power pin into the rear
block using a 1” (25 mm) wrench on
the rear block and a 5/8” (16 mm) or
3/4” (19 mm) wrench on the power pin.
Option #2 of 2: Euro Connection
The Euro connection comes factory installed.
No installation required.
STEP #7 - INSTALLING QUICK LOAD LINER
Remove the rear cap of the power pin.
Insert brass end of liner into the liner retainer until firmly seated.
Insert non-brass end of QUICK LOAD™Liner into back of the gun and push through until it emerges from the
front of the gun and the liner retainer makes contact with the
power pin.
Thread the QUICK LOAD Liner retainer (#415-26) into the
power pin. Torque to 30 in.-lbs. (3.5 Nm).
Re-thread the cap of the power pin back on (hand tighten).
Push liner back into front of gun and hold in place.
Trim liner to a 5/8” (16 mm) stick out.
Remove any burrs that may obstruct wire feed.

STEP #8 - INSTALLING CONSUMABLES
Retaining Head
Thread the retaining head onto the neck.
Use a 5/8” wrench and tighten to 80 in.-lbs. (or 9 Nm).
Contact Tip
Thread the contact tip into the retaining head.
Torque to 30 in.-lbs. (3.5 Nm).
Nozzle
Press the slip-on TOUGH GUN Nozzle over the retaining head/contact tip combo until the nozzle is
fully seated.
IMPORTANT: Be sure all consumables are tightened properly and fully seated before welding to
prevent overheating.
STEP #9 - INSTALLING GUN TO WIRE FEEDER
Feed the cable through the hole in the body of the robot.
Install the control cable (for LSR Systems with Clutches ONLY).
oConnect the jumper control cable to the main control cable of the LSR System.
oConnect to the wire feeder as per the manufacturer’s instructions.
Install into wire feeder as per the manufacturer’s instructions.

3.0 –MAINTENANCE
3.1 REPLACEMENT / ADJUSTMENT OF CLUTCH LIMIT SWITCH
Feed wires of switch through center holes of switch base and jam nut as shown in exploded view.
Thread switch base far enough down on the switch body so that the switch will not bottom out when the
assembly is fastened to the clutch.
Position switch assembly (with o-ring) in the clutch housing.
Insert the two M3 x 0.5 x 6 Hex SHCS into the holes in the switch base and fasten assembly to the clutch.
Adjust switch by rotating switch itself in the switch base to the appropriate depth. Check normally closed
switch using ohmmeter to set desired level of sensitivity.
Once desired sensitivity is achieved, lock position of switch by torquing jam nut (50 in.-lbs./5.6 Nm)
against switch base.

FINISHED ASSEMBLY
3.2 REPLACEMENT OF EURO CONNECTION
Remove M5 x 6mm countersunk
fasteners.
Slide the hand nut over the Euro power
pin body.
Torque the power pin body to the
threaded end of the unicable at 18 ft.-lbs.
(24 Nm) using 7/8” & 13/16” wrenches.
You may have to pull back on the outer
conduit to achieve this.
Once the power pin body is in place, pull
the conduit down over it. Rotate the
conduit so that the holes on the power pin
line up with the holes on the plastic end of
the conduit.

Nm). You may have to rotate the hand nut
to access the holes.
3.3 REPLACEMENT OF QUICK LOAD
™LINER
Remove the rear cap of the power pin.
Remove the QUICK LOAD Liner retainer (#415-
26) from the power pin and thread in new one.
Torque to 30 in.-lbs. (3.5 Nm). NOTE: One liner
retainer can last for multiple liner replacements.
Therefore this step is not required for every liner
change.
Re-thread the cap of the power pin back on
(hand tighten).
Next, install QUICK LOAD Liner through front of
gun (neck).
Ensure liner is completely seated in retainer at
rear of cable.
Push liner back into front of gun and hold in
place.
Trim liner to a 5/8” (16 mm) stick out.
Remove any burrs that may obstruct wire feed.
