BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
FOR ENGINE POWERED
EQUIPMENT.
1.a. Turn the engine off before troubleshooting
and maintenance work unless the
maintenance work requires it to be running.
1.b. Operate engines in open, well-ventilated areas or vent the engine
exhaust fumes outdoors.
1.c. Do not add the fuel near an open flame welding
arc or when the engine is running. Stop the
engine and allow it to cool before refueling to
prevent spilled fuel from vaporizing on contact
with hot engine parts and igniting. Do not spill fuel when filling
tank. If fuel is spilled, wipe it up and do not start engine until
fumes have been eliminated.
1.d. Keep all equipment safety guards, covers
and devices in position and in good repair.
Keep hands, hair, clothing and tools away
from V-belts, gears, fans and all other
moving parts when starting, operating or
repairing equipment.
1.e. In some cases it may be necessary to remove safety guards to
perform required maintenance. Remove guards only when
necessary and replace them when the maintenance requiring
their removal is complete. Always use the greatest care when
working near moving parts.
1.f. Do not put your hands near the engine fan. Do not attempt to
override the governor or idler by pushing on the throttle control
rods while the engine is running.
1.g. To prevent accidentally starting gasoline engines while turning
the engine or welding generator during maintenance work,
disconnect the spark plug wires, distributor cap or magneto wire
as appropriate.
1.h. To avoid scalding, do not remove the radiator
pressure cap when the engine is hot.
ELECTRIC AND
MAGNETIC FIELDS MAY
BE DANGEROUS
2.a. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF).
Welding current creates EMF fields around welding cables
and welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health effects
which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1. Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the
work cable should also be on your right side.
2.d.4. Connect the work cable to the workpiece as close as pos-
sible to the area being welded.
2.d.5. Do not work next to welding power source.
SAFETY
Safety 02 of 04 - 5/16/2018

ELECTRIC SHOCK
CAN KILL.
3.a. The electrode and work (or ground) circuits are
electrically “hot” when the welder is on. Do
not touch these “hot” parts with your bare skin or wet clothing.
Wear dry, hole-free gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full area
of physical contact with work and ground.
In addition to the normal safety precautions, if
welding must be performed under electrically
hazardous conditions (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, if there
is a high risk of unavoidable or accidental contact
with the workpiece or ground) use the following
equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical (earth)
ground.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of electrode
holders connected to two welders because voltage
between the
two can be the total of the open circuit voltage of both
welders.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.
3.j. Also see Items 6.c. and 8.
ARC RAYS CAN BURN.
4.a. Use a shield with the proper filter and cover plates to protect your
eyes from sparks and the rays of the arc when welding or
observing open arc welding. Headshield and filter lens should
conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant material
to protect your skin and that of your helpers from the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES
CAN BE DANGEROUS.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep your head out of the fume.
Use enough ventilation and/or exhaust at the arc to keep fumes
and gases away from the breathing zone. When welding
hardfacing (see instructions on container or SDS)
or on lead or cadmium plated steel and other
metals or coatings which produce highly toxic
fumes, keep exposure as low as possible and
within applicable OSHA PEL and ACGIH TLV limits
using local exhaust or mechanical ventilation
unless exposure assessments indicate otherwise.
In confined spaces or in some circumstances,
outdoors, a respirator may also be required.
Additional precautions are also required when
welding
on galvanized steel.
5. b. The operation of welding fume control equipment is affected by
various factors including proper use and positioning of the
equipment, maintenance of the equipment and the specific
welding procedure and application involved. Worker exposure
level should be checked upon installation and periodically
thereafter to be certain it is within applicable OSHA PEL and
ACGIH TLV limits.
5.c. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.
5.d. Shielding gases used for arc welding can displace air and
cause
injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
Safety Data Sheet (SDS) and follow your employer’s safety
practices. SDS forms are available from your welding
distributor or from the manufacturer.
5.f. Also see item 1.b.
SAFETY
Safety 03 of 04 - 5/16/2018

WELDING AND CUTTING
SPARKS CAN CAUSE
FIRE OR EXPLOSION.
6.a. Remove fire hazards from the welding area. If
this is not possible, cover them to prevent the welding sparks
from starting a fire. Remember that welding sparks and hot
materials from welding can easily go through small cracks and
openings to adjacent areas. Avoid welding near hydraulic lines.
Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special
precautions should be used to prevent hazardous situations.
Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1)
and the operating information for the equipment being used.
6.c. When not welding, make certain no part of the electrode circuit is
touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous Substances”,
AWS F4.1 from the American Welding Society
(see address above).
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free
protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes and a cap over your hair. Wear ear plugs
when welding out of position or in confined places. Always wear
safety glasses with side shields when in a welding area.
6.g. Connect the work cable to the work as close to the welding area
as practical. Work cables connected to the building framework or
other locations away from the welding area increase the
possibility of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire
hazards or overheat lifting chains or cables until they fail.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, MA 022690-9101.
6.j. Do not use a welding power source for pipe thawing.
CYLINDER MAY EXPLODE IF
DAMAGED.
7.a. Use only compressed gas cylinders containing
the correct shielding gas for the process used
and properly operating regulators designed for
the gas and pressure used. All hoses, fittings,
etc. should be suitable for the application and
maintained in good condition.
7.b. Always keep cylinders in an upright position securely chained to
an undercarriage or fixed support.
7.c. Cylinders should be located:
• Away from areas where they may be struck or subjected
to physical damage.
• A safe distance from arc welding or cutting operations
and any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand tight
except when the cylinder is in use or connected for use.
7.g. Read and follow the instructions on compressed gas cylinders,
associated equipment, and CGA publication P-l, “Precautions for
Safe Handling of Compressed Gases in Cylinders,” available from
the Compressed Gas Association, 14501 George Carter Way
Chantilly, VA 20151.
FOR ELECTRICALLY
POWERED EQUIPMENT.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National Electrical
Code, all local codes and the manufacturer’s recommendations.
8.c. Ground the equipment in accordance with the U.S. National

PRODUCT DESCRIPTION X-TRACTOR 1GC
GENERAL DESCRIPTION
The X-Tractor 1 C is a self contained system for the removal and
filtration of welding fume particles and other point source particu-
late. It is a high vacuum, low volume system with the capability to
easily and comfortably clean the filter cartridge with compressed
air. It is suitable for medium duty welding applications. When in
“Auto” mode, a current sensor turns the system on only when
needed, thereby extending the brush life of the motors. The sys-
tem is powered by two 120V or 230V blowers.
Machines manufactured after April, 1997 have a circuit breaker
and a Mode switch that allows selection of Low/High Mode. When
in “Low” mode, only one of the two blowers operates; when in
“High” mode, both blowers operate. Machines built after April,
1999 have a Low/High mode switch, but use circuit protection
built-in to the main power switch rather than a circuit breaker.
The X-Tractor 1 C is designed to supply suction for one fume gun
or small suction head designed for High Vacuum fume extraction.
Air enters the system through a 2" (50mm) OD connection. It then
passes through a heavy particle trap, then through the filter, leav-
ing fume particles on the outside of the cartridge. This particulate
free air then passes through the blower and exits through the side
of the machine.
When the filter becomes loaded with fume particles, the filter is
cleaned with compressed air while still inside the machine. By
connecting compressed air to the fitting on the rear of the
machine and rotating the fitting, particles are blown from the out-
side surface of the filter by air jets released from the cleaning
device. The internal canister is then removed and particulate can
be poured out.

SAFETY INSTRUCTI NS
Do not attempt to use this equipment until you have thoroughly
read all operating and maintenance manuals supplied with your
equipment and any related welding machine it will be used with.
They include important safety precautions, operating and main-
tenance instructions and parts lists.
ELECTRIC SH CK can kill.
• Do not touch electrically live parts such as
output terminals or internal wiring.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
--------------------------------------------------------------------
WELDING SPARKS can cause fire or explo-
sion.
• Keep flammable material away.
• Do not weld upon containers which have
held combustibles.
--------------------------------------------------------------------
ARC RAYS can burn.
• Wear eye, ear and body protection.
--------------------------------------------------------------------
FUMES AND GASES
can be dangerous.
• Although the removal of the particulate
matter from welding smoke may reduce
the ventilation requirement, concentra-
tions of the clear exhausted fumes and
gases may still be hazardous to health.
Avoid breathing concentrations of these
fumes and gases. Use adequate ventila-
tion when welding. See ANSI Z49.1,
"Safety in Welding and Cutting", pub-
lished by the American Welding Society.
--------------------------------------------------------------------
nly qualified personnel should operate this equipment.
ADDITI NAL SAFETY PRECAUTI NS
Always operate this equipment with the filters installed and cov-
ers in place as these provide maximum protection from moving
parts and insure proper vacuum operation and cooling air flow.
WARNING
PERATING INSTRUCTI NS
The X-Tractor 1 C provides enough suction for one fume gun or
small suction head. When in “Low” mode, only one blower oper-
ates, when in “High” mode, both blowers operate. When in the
“Man” mode, the X-Tractor 1 C will run continuously. When in
the “Auto” mode, it will turn on only when current is sensed by
the current sensor.
USIN THE “AUTO” MODE
Loop a section of the work cable or electrode cable through the
hook at the rear of the machine. When using welding current of
less than 80 Amps, loop the cable through twice. When using
welding current of less than 40 Amps loop the cable through
three times. When the arc starts, the current flowing through
the cable will create a magnetic field. The current sensor
mounted in the machine behind the loop will sense this field and
start the machine. When the arc stops, there is a ten second
delay before the machine shuts down.

MAINTENANCE
X-TRACTOR 1GC
R UTINE MAINTENANCE
The Filter should be cleaned and the canister emptied on a regular
basis. Frequency of cleaning and emptying depends upon a num-
ber of factors such as the type of welding fume and the frequency
of use. In many cases, a good procedure would be to clean the fil-
ter once per week and empty the canister once per month.
CLEANING THE FILTER
When the performance of the system decreases, this indicates
that the filter should be cleaned.
1. Disconnect the machine from input power.
2. Close the inlet with the rubber plug.
3. Connect compressed air to the fitting on the rear of the
machine and open the ball valve on the fitting.
4. Rotate the fitting 200°, back and forth 6 - 7 times. This will
rotate the cleaning device inside the machine, distributing the
jets of compressed air over the circumference of the filter.
5. Close the ball valve and disconnect the compressed air.
6. Remove the plug from the inlet and reconnect to input power.
EMPTYING THE CANISTER AND HEAVY
PARTICLE TRAP
The particulate matter collected in the canister may be dan-
gerous to your health. Take necessary precautions so that
you and your fellow workers do not breathe the dust and
particulate. Wear a suitable respirator when disposing of the
particulate.
Check with local authorities for regulations governing the
disposal of this material.
--------------------------------------------------------------------
WARNING
1. Clean the filter.
2. Open the quick-release fasteners on the four corners of the
case front by rotating the fasteners 1/4 turn. (See Fig. 1)
3. Remove the canister by pulling on the handle and stand the
canister with the case front on top.
4. Open the two other quick-release fasteners (at the top and
bottom of the case front) by rotating 1/4 turn. Remove the
case front from the canister.
5. Empty the canister.
6. Empty the heavy particle trap built into the case front.
7. Replace the case front by rotating the quick-release fasteners
to the “closed” position: the fastener will line up with the
lines in the case. In this position they are parallel with the
case side (See Fig. 1). With the fasteners in this position,
place the case front onto the canister and press the quick-
release fasteners into the two holes. When they “click”, they
are fastened. If they do not “click” or fasten, then check to
see that they are in the closed position described above.
8. Replace the canister into the machine with the inlet on the
bottom. Fasten the case front to the machine using the pro-
cedure outlined in step 7.

MAINTENANCE
X-TRACTOR 1GC
REPLACING THE FILTER
The filter is a long life, polyester filter designed to be repeatedly
cleaned by compressed air. Therefore, it should need replace-
ment only after an extended period of time. Certain applications
can reduce this period, especially very oily smoke or excessive
moisture. Replacement is necessary when, after several clean-
ing cycles, the suction performance of the system is still lower
than normal or due to mechanical damage to the filter. Overall
filter life depends on a great number of variables such as type of
fume, duty cycle, operating factor, capture efficiency, etc.
The particulate matter collected in the canister may be dan-
gerous to your health. Take necessary precautions so that
you and your fellow workers do not breathe the dust and
particulate. Wear a suitable respirator when disposing of
the particulate.
Check with local authorities for regulations governing the
disposal of used filters.
