hazards. When you see the symbol, watch out, and
follow the related instructions to avoid the hazard. The safety
information given below is only a summary of the more complete
safety information found in the Principal Safety Standards
section. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain,
and repair this equipment. A qualified person is defined
as one who, by possession of a recognized degree,
certificate, or professional standing, or who by extensive
knowledge, training and experience, has successfully
demonstrated ability to solve or resolve problems relating to the
subject matter, the work, or the project and has received safety
training to recognize and avoid the hazards involved.
During operation, keep everybody, especially children,
away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is on.
The input power circuit and machine internal
circuits are also live when power is on. In semi-
automatic or automatic wire welding, the wire, wire
reel, drive roll housing, and all metal parts
touching the welding wire are electrically live.
Incorrectly installed or improperly grounded equipment is a
hazard.
lDo not touch live electrical parts.
lWear dry, hole-free insulating gloves and body protection.
lInsulate yourself from work and ground using dry insulating
mats or covers big enough to prevent any physical contact
with the work or ground.
lDo not use ACweld output in damp, wet, or confined
spaces, or if there is a danger of falling.
lUse ACoutput ONLY if required for the welding process.
lIf AC output is required, use remote output control if present
on unit.
lAdditional safety precautions are required when any of the
following electrically hazardous conditions are present: in
damp locations or while wearing wet clothing; on metal
structures such as floors, gratings, or scaffolds; when in
cramped positions such as sitting, kneeling, or lying; or
when there is a high risk of unavoidable or accidental
contact with the workpiece or ground. For these conditions,
use the following equipment in order presented: 1) a semi-
automatic DCconstant voltage (wire) welder, 2) a DCmanual
(stick) welder, or 3) an ACwelder with reduced open-circuit
voltage. In most situations, use of a DC, constant voltage
wire welder is recommended. And, do not work alone!
lDisconnect input power or stop engine before installing or
servicing this equipment. Lockout/tagout input power
according to OSHA 29 CFR 1910.147 (see Principal Safety
Standards).
lProperly install, ground, and operate this equipments
according to its Owner's Manual and national, state, and
local codes.
lAlways verify the supply ground – check and be sure that
input power cord ground wire is properly connected to
ground terminal in disconnect box or that cord plug is
connected to a properly grounded receptacle outlet.
lWhen making input connections, attach proper grounding
conductor first – double-check connections.
lKeep cords dry, free of oil and grease, and protected from
hot metal and sparks.
lFrequently inspect input power cord and ground conductor
for damage or bare wiring – replace immediately if damaged
– bare wiring can kill.
OM-TT3-1.4 1
SECTION 1 — SAFETY PRECAUTIONS — READ BEFORE USING

lTurn off all equipment when not in use.
lDo not use worn, damaged, undersized, or repaired cables.
lDo not drape cables over your body.
lIf earth grounding of the workpiece is required, ground it
directly with a separate cable.
lDo not touch electrode if you are in contact with the work,
ground, or another electrode from a different machine.
lDo not touch electrode holders connected to two welding
machines at the same time since double open-circuit voltage
will be present.
lUse only well-maintained equipment. Repair or replace
damaged parts at once. Maintain unit according to Manual.
lWear a safety harness if working above floor level.
lKeep all panels and covers securely in place.
lClamp work cable with good metal-to-metal contact to
workpiece or worktable as near the weld as practical.
lInsulate work clamp when not connected to workpiece to
prevent contact with any metal object.
lDo not connect more than one electrode or work cable to
any single weld output terminal. Disconnect cable for
process not in use.
lUse GFCI protection when operating auxiliary equipment in
damp or wet locations.
SIGNIFICANT DC VOLTAGE exists in inverter welding
power sources AFTERremoval of input power.
lTurn off unit, disconnect input power, and discharge input
capacitors according to instructions in Manual before
touching any parts.
HOT PARTS can burn.
lDo not touch hot parts bare handed.
lAllow cooling period before working on
equipment.
lTo handle hot parts, use proper tools and/or wear heavy,
insulated welding gloves and clothing to prevent burns.
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
lKeep your head out of the fumes. Do not breathe the fumes.
lVentilate the work area and/or use local forced ventilation at
the arc to remove welding fumes and gases. The
recommended way to determine adequate ventilation is to
sample for the composition and quantity of fumes and
gases to which personnel are exposed.
lIf ventilation is poor, wear an approved air-supplied
respirator.
lRead and understand the Safety Data Sheets (SDSs) and the
manufacturer's instructions for adhesives, coatings,
cleaners, consumables, coolants, degreasers, fluxes, and
metals.
lWork in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained
watch-person nearby. Welding fumes and gases can
displace air and lower the oxygen level causing injury or
death. Be sure the breathing air is safe.
lDo not weld in locations near degreasing, cleaning, or
spraying operations. The heat and the rays of the arc can
react with vapors to form highly toxic and irritating gases.
lDo not weld on coated metals, such as galvanized, lead, or
cadmium plated steel, unless the coating is removed from
the weld area, the area is well ventilated, and while wearing
an air-supplied respirator. The coatings and any metals
containing these elements can give off toxic fumes if
welded.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the
weld.
lWear an approved welding helmet fitted with a proper shade
of filter lenses to protect your face and eyes from arc rays
and sparks when welding or watching (see ANSI Z49.1 and
Z87.1 listed in Principal Safety Standards).
lWear approved safety glasses with side shields under your
helmet.
lUse protective screens or barriers to protect others from
flash, glare and sparks; warn others not to watch the arc.
lWear body protection made from durable, flame-resistant
material (leather, heavy cotton, wool). Body protection
includes oil-free clothing such as leather gloves, heavy shirt,
cuffless trousers, high shoes, and a cap.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up.
Sparks can fly off from the welding arc. The flying
sparks, hot workpiece, and hot equipment can
cause fires and burns. Accidental contact of
electrode to metal objects can cause sparks, explosion,
overheating, or fire. Check and be sure the area is safe before
doing any welding.
lRemove all flammables within 35 ft (10.7 m) of the welding
arc. If this is not possible, tightly cover them with approved
covers.
lDo not weld where flying sparks can strike flammable
material.
lProtect yourself and others from flying sparks and hot metal.
2 OM-TT3-1.4

lBe alert that welding sparks and hot materials from welding
can easily go through small cracks and openings to adjacent
areas.
lWatch for fire, and keep a fire extinguisher nearby.
lBe aware that welding on a ceiling, floor, bulkhead, or
partition can cause fire on the hidden side.
lDo not cut or weld on tire rims or wheels. Tires can explode
if heated. Repaired rims and wheels can fail. See OSHA 29
CFR 1910.177 listed in Principal Safety Standards.
lDo not weld on containers that have held combustibles, or
on closed containers such as tanks, drums, or pipes unless
they are properly prepared according to AWS F4.1 and AWS
A6.0 (see Principal Safety Standards).
lDo not weld where the atmosphere can contain flammable
dust, has, or liquid vapors (such as gasoline).
lConnect work cable to the work as close to the welding area
as practical to prevent welding current from traveling long,
possibly unknown paths and causing electric shock, sparks,
and fire hazards.
lDo not use welder to thaw frozen pipes.
lRemove stick electrode from holder or cut off welding wire
at contact tip when not in use.
lWear body protection made from durable, flame-resistant
material (leather, heavy cotton, wool). Body protection
includes oil-free clothing such as leather gloves, heavy shirt,
cuffless trousers, high shoes, and a cap.
lRemove any combustibles, such as a butane lighter or
matches, from your person before doing any welding.
lAfter completion of work, inspect area to ensure it is free of
sparks, glowing embers, and flames.
lUse only correct fuses or circuit breakers. Do not oversize or
bypass them.
lFollow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA
51B for hot work and have a fire watcher and extinguisher
nearby.
lRead and understand the Safety Data Sheets (SDSs) and the
manufacturer's instructions for adhesives, coatings,
cleaners, consumables, coolants, degreasers, fluxes, and
metals.
FLYING METAL or DIRT can injure eyes.
lWelding, chipping, wire brushing, and
grinding cause sparks and flying metal. As
welds cool, they can throw off slag.
lWear approved safety glasses with side shields even under
your welding helmet.
BUILDUP OF GAS can injure or kill.
lShut off compressed gas supply when not in
use.
lAlways ventilate confined spaces or use approved air-
supplied respirator.
ELECTRIC AND MAGNETIC FIELDS (EMF) can
affect Implanted Medical Devices.
lWearers of Pacemakers and other Implanted
Medical Devices should keep away.
lImplanted Medical Device wearers should consult their
doctor and the device manufacturer before going near arc
welding, spot welding, gouging, plasma arc cutting, or
induction heating operations.
NOISEcan damage hearing.
Noise from some processes or equipment can
damage hearing.
lWear approved ear protection if noise level is
high.
CYLINDERS can explode if damaged.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the
welding process, be sure to treat them carefully.
lProtect compressed gas cylinders from excessive heat,
mechanical shocks, physical damage, slag, open flames,
sparks, and arcs.
lInstall cylinders in an upright position by securing to a
stationary support or cylinder rack to prevent falling or
tipping.
lKeep cylinders away from any welding or other electrical
circuits.
lNever drape a welding torch over a gas cylinder.
lNever allow a welding electrode to touch any cylinder.
lNever weld on a pressurized cylinder – explosion will result.
lUse only correct compressed gas cylinders, regulators,
hoses, and fittings designed for the specific application;
maintain them and associated parts in good condition.
lTurn face away from valve outlet when opening cylinder
valve. Do not stand in front of or behind the regulator when
opening the valve.

1-4 California Proposition 65 Warnings
WARNING: This product can expose you to chemicals including
lead, which are known to the state of California to cause cancer
and birth defects or other reproductive harm.
For more information, go to www.P65Warnings.ca.gov.
1-5 EMF Information
Electric current flowing through any conductor causes localized
electric and magnetic fields (EMF). The current from arc welding
(and allied processes including spot welding, gouging, plasma arc
cutting, and induction heating operations) creates an EMF field
around the welding circuit. EMF fields may interfere with some
medical implants, e.g. Pacemakers. Protective measures for
persons wearing medical implants have to be taken. For example,
restrict access for passersby or conduct individual risk assessment
for welders. All welders should use the following procedures in
order to minimize exposure to EMF fields from the welding circuit:
1. Keep cables close together by twisting or taping them, or
using a cable cover.
2. Do not place your body between welding cables. Arrange
cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep head and trunk as far away from the equipment in the
welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as
possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld while carrying the welding power source wire
feeder.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and
the device manufacturer before performing or going near arc
welding, spot welding, gouging, plasma arc cutting, or induction
heating operations. If cleared by your doctor, then following the
above procedures is recommended.

3-3 Installing Nozzle Detect
WARNING: Ensure air and power supply is off and disconnected
before proceeding. Please follow your facility's lockout / tagout
procedures.
NOTE:This nozzle detect sensor has a sensing range of 5 mm and
can detect any metallic part that comes within this sensing range.
The accuracy is ± ≤2% (0.1 mm). The circuit is normally open until
the sensor detects a metallic part within its sensing range. The
green LEDon the sensor will always be on if there is power to the
reamer.
A. Mounting Nozzle Detect
1. Using two (2)M3x0.5x16 mm SHCS, attach the nozzle detect
to the side of the clamp housing in the two threaded
holes.Torque to 8-10 in-lbs.
2. Connect the supplied 4 Pin cable to the sensor and wire back
to PLC / Robot Controller for monitoring.

4-1 Air Motor Lubricator
WARNING: The TOUGH GUN Reamer must be operated with lubricated air using either the air motor lubricator option or a suitable
alternative system installed by the customer. The lubricator should be set to feed one drop of oil for every 50-75 CFM of air going
through the motor (approximately 1 drop every 5-10 cycles or 1 drop per minute of operation). The lubricant can be air motor oil or
light grade hydraulic oil with a viscosity rating of 150 VC 15-20 (SAE 5W).
4-2 Accessing Electrical and Pneumatic Controls
WARNING: Ensure power supply is off and disconnected before proceeding. Please follow your facility's lockout / tagout procedures.
To access the electronic circuit board for installation or service for the TOUGH GUN Reamer:
1. Remove reservoir (if equipped) and loosen the two (2) BHCS using a 3 mm Allen wrench to open the hinged rear access door.
2. The rear access door can be completely removed if accessibility is an issue. To do so, using a 3 mm Allen wrench, remove the (3)
BHCS which fasten the hinge to the frame.

4-3 Wiring Interface Connections
WARNING: The following connection should only be performed by a qualified technician. Damage to equipment will occur if
connections are incorrect.
To interface the TOUGH GUN Reamer with the controller, five
(5)electrical connections are required:
lORANGE LEAD: Cycle Start output from PLC / controller (0.25
amp)
lWHITE LEAD: 0 VDC supply 0.5 amp constant
lRED LEAD: 24 VDC supply 0.5 amp constant
lGREEN LEAD: Home Signal Jaws Unclamped input to PLC/
controller (0.25 amp)
lBLACK LEAD: Sprayer output from PLC/ controller (0.25 amp)
NOTE: The pre-wired interface receptacle uses the above color
codes.
The circuit board of the reamer is capable of both sourcing or
sinking inputs and outputs:
lPin 1 (WHITE LEAD): 0 CONSTANT VDC
0 VDC operates the board for both Sourcing or Sinking settings
lPin 2 (RED LEAD): +24 CONSTANT VDC
+24 VDCoperates the board for both Sourcing or Sinking
settings
lPin 3 (GREEN LEAD): Reamer Home signal
Choose one of two settings:
1. Sourcing - When unit is in Home position, reamer sends
HIGHsignal (+24 VDC) back to PLC / controller
2. Sinking - When unit is in Home position, reamer sends
LOW signal (0VDC) signal back to PLC / controller
lPin 4 (ORANGE LEAD): Cycle Start signal (signal should be a
pulse with a maximum of 0.5 seconds in duration)
Choose one of two settings:
1. To initiate the ream cycle, set board to Sourcing,
controller sends HIGH signal (+24 VDC) to reamer
2. To initiate the ream cycle, set board to Sinking, controller
sends LOWsignal (0VDC) to reamer
lPin 5 (BLACK LEAD):Sprayer Start signal
+24 VDC operates the sprayer for both Sourcing or Sinking
settings
NOTE:See section 4-4 Inversing Circuit Board Logic on page 15 for
more information.

4-4 Inversing Circuit Board Logic
WARNING: Before start-up, ensure that all connections are correct,
or damage to the TOUGH GUN Reamer will occur.
The TOUGH GUN Reamer is factory set for Sourcing inputs and
outputs.
DEFINITIONS:
lSinking = signal from PLC/ controller is LOW(0VDC)
lSourcing = signal from PLC / controller is HIGH (+24 VDC)
(see section 7-2 Electrical Schematic on page 30).
The control logic requirement for some installations may require
an inverse of the logic provided.
To switch from Sourcing to Sinking:
The switches located inside the rear access door must be
accessed. See section 4-2 Accessing Electrical and Pneumatic
Controls on page 13 for directions.
1. Disconnect from power supply.
2. Move the switches to the desired positions (SRCor SNK).
3. Connect power back into the reamer.
IMPORTANT NOTE: Although the circuit board is protected,
Tregaskiss suggests disconnecting the power before moving the
switches.
The switches are located on the top left hand corner of the
circuit board (SRC = Sourcing, SNK = Sinking)
lSprayer signal can be set to either SRC or SNK by moving
the switch (SW1 - Option) to the position indicated in Figure
4-B.
lCycle Start signal can be set to either SRC or SNK by moving
the switch (SW2 - Start) to the position indicated in Figure 4-
B.
lReamer Home signal can be set to either SRC or SNK by
moving the switch (SW3 - Unclamped) to the position
indicated in Figure 4-B.
