INPUT VOLTAGE CONNECTIONS
NOTE:
Machines are shipped from the factory connected
for HIGH Voltage per the following instructions.
Over 300 Volts
1.
Connect the three input lines to L1, L2 & L3 on starter.
2.
Connect lead H3 from pilot transformer to L3 on starter
and tape up lead H2.
3.
Remove motor junction box cover.
4.
Reconnect motor using HIGH VOLTAGE connection dia-
gram on junction box cover or fan housing & connect to
starter leads T1, T2 & T3.
5.
Connect Ground lead to terminal marked
.
6.
Tighten all screws and replace covers.
7.
Check motor rotation with arrow on blower housing. If
incorrect interchange any two input lines.
Under 300 Volts
1.
Connect the three input lines to L1, L2 & L3 on starter.
2. Connect lead H2 from pilot transformer to L3 on starter
and tape up lead H3.
3.
Remove motor junction box cover.
4.
Reconnect motor using LOW VOLTAGE connection dia-
gram on junction box cover or fan housing & connect to
starter leads T1, T2 & T3.
5.
Connect Ground lead to terminal marked
.
6.
Tighten all screws and replace covers.
7.
Check motor rotation with arrow on blower housing. If
incorrect interchange any two input lines.
A muffler is shipped loose and is used to reduce the
noise created by the vacuum motor. The muffler is to
be attached to the pipe nipple coming from the
exhaust port of the vacuum motor.
The shaker handle is also shipped loose. The shaker
handle must be fastened to the shaft on the side of
the cabinet using the square key and two set screws
provided.
Connect a 1-3/4" (45 mm) exhaust hose (Lincoln
Electric has 1-3/4" hoses for both regular duty (PVC
flex hose S19947- ) and heavy duty (reinforced rubber
S14927-8) applications) to the supplied hose adapter,
and then connect the adapter to the open inlet fitting
on the back of the unit. When one gun is used, the
orifice in the stopper of second inlet tube must not be
covered. Failure to keep this orifice open will reduce
vacuum motor bearing life. If two guns are to be
used on the X-tractor 2G, remove stopper with orifice
from the second inlet fitting before attaching the gun
exhaust hose.
Note:When new units are first started, some visible
smoke may appear at the exhaust for about 15 min-
utes of arc time. This should clear completely by the
end of that time.
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", published
by the American Welding Society.
------------------------------------------------------------------------
EXHAUST EXTENSION
Some installations may require an exhaust extension
to couple the unit to a ventilating duct or to vent the
fumes outdoors. Attach an adequate exhaust exten-
sion on the muffler outlet of the vacuum motor.
Single Gun Operation: To insure good smoke pickup,
back pressure at the muffler exhaust should be limited
to five inches of water. A 30-foot length of two inch
diameter exhaust hose will keep the back pressure
below five inches of water.
Two Gun Operation: To insure good smoke pickup,
back pressure at the muffler exhaust should be limited
to two inches of water. A 30-foot length of three inch
diameter exhaust hose will keep the back pressure
below two inches of water
The back pressure values given above should be
used as guidelines and the user may exceed these
values to suit his application and smoke removal
requirements. When noise is not objectionable, the
muffler may be removed to reduce overall back pres-
sure.

*Note On 50 hertz operation the vacuum ratings of the motors will
be reduced due to change in motor speed. On 50 hertz
power, X-tractor 2G will provide enough vacuum for opera-
tion of one gun or marginal smoke pickup if two guns are
used.
