GENERAL DESCRIPTION
The arc welding smoke exhaust unit will provide the
vacuum needed for one X-Tractor or Flux-Cored Fume
gun, collect visible particles that enter and discharge
the filtered air. This vacuum does not filter out gases.
The X-Tractor 1G is particularly valuable for light duty,
intermittent operation where frequent location changes
and low equipment costs are of prime importance. The
unit weighs 45 pounds and contains a reusable filter
element that collects the particulate matter. The filter
can be cleaned and reused.
A control circuit connected to the wire feeder slows the
motor to 1/2 speed when welding stops. With proper
maintenance, the average motor life is 2,000 hours.
The smoke exhaust system consists of a vacuum
motor mounted on a canister with a filter mounted
inside the canister. See Figure 1 for nominal vacuum
motor output characteristics. The vacuum motor is
attached to the lid of the canister. A cover over the
motor provides both a drip-proof covering and a mount-
ing support for the switch and other electrical compo-
nents. A baffle is built into the cover to prevent re-cir-
culation of the motor cooling air. The switch turns the
unit on and lights a pilot light. A relay and resistors per-
mit the motor to run at half speed when not welding to
increase motor life. This allows enough air flow to cool
the gun when not welding and reduces the motor's
starting current. Operable from either 115 volts AC or
DC, the relay is energized when the operator pulls the
gun trigger.
The filter, made of a paper media, is attached to the
inside of the canister lid. Filters for these units are sim-
ilar to those used for large engine air cleaners. The
inlet pipe is fastened to the bottom of the canister and
is mounted tangentially to the inside diameter. A baffle
is mounted above the inlet pipe. When smoke and
sparks enter the canister, the sparks and heavier
smoke particles are retained in the bottom of the can-
ister by a centrifugal action. The centrifugal action and
baffle prevent sparks from damaging the filter media.
A muffler is standard to suppress the noise level of the
vacuum motor when operating at full speed. A hose
adapter is provided to allow easy connection of the
vacuum to any 1-3/4" (45 mm) exhaust hose. Lincoln
Electric has 1-3/4" hoses for both regular duty (PVC
flexhose S19947- ) and heavy duty (Reinforced rubber
S14927-8) applications.
