Lincoln Electric 1GX manual Connection to the Gun and Cable Assembly, Locating the Vacuum Source

A-3 INSTALLATION A-3

In order to take advantage of the automatic stop/start feature of the K173-2, the work cable from the power source needs to be routed through the sensor located at the motor end of the vacuum source. This sensor, or cable holder, is located on top of the plastic motor housing and has two bristle brushes on it which keep the cable in place. For low current welding applica- tions, the work cable may need to be routed through the cable holder twice to assure 100% performance of the sensor.

Connection to the Gun and Cable Assembly

The hose adapter supplied will mate with 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 14927-8) applica- tions. Simply connect the hose adapter to the hose and connect the adapter to the K173-2. Do the same at the other end of the hose with the gun or suction head being used.

Tighten the hose clamps to keep the hose in place.

Locating the Vacuum Source

Because of its size and weight, the X-Tractor 1GX can be located almost anywhere in the work area. Since only particulate matter is filtered out of the air and because the unfiltered gases may contain odors, it is recommended that the vacuum be placed away from the user and other personnel as far as convenient with- in the constraints of the hoses and cables.

The filter cabinet of the 1GX is not pressurized, so it is possible to drill holes in the sheet metal box without affecting performance. This means that a more per- manent mounting can be achieved by bolting or screw- ing the vacuum to a power source or other nearby equipment. If this type of mounting is desired:

a)Physically check that the vacuum will fit in the desired location, and that the spark trap and filter cartridge can still be maintained after the installation. This may require that a special spacer or washer be made to keep the vacuum spaced away from the other equipment.

b)Remove the spark trap, filter cartridge, and blower/motor assembly from the cabinet.

c)Carefully remove the panel from the power source or other equipment that the vacuum will be mounted to, following all warnings and

instructions provided with that equipment.

d)Mark and drill both the vacuum cabinet and the other panel for the fasteners to be used.

e)Fasten the cabinet to the mating panel, using any spacers if they are required. Carefully choose fasteners with flat heads or other low type head so they don’t interfere inside the vacuum cabinet with filter installation.

f)Carefully reassemble and connect both the power source (or other equipment) and the vacuum unit.
