STATOR REMOVAL PROCEDURE

1.Conduct this procedure with the engine OFF.

2.With the 5/16” and 3/8” nut drivers, remove the screws from the case top and right and left case sides. If necessary, use the 1/2” socket wrench to remove the exhaust pipe from the muffler.

3.Remove the right and left case sides. Then remove the negative (-) and positive

(+) cables from the battery.

4.Remove the rubber gasket (cover seal) from the lift bail.

5.Remove the fuel cap and the rubber gas- ket for the fill tube.

6.Unlatch the double door assembly and use the slot head screw driver and 3/8” wrench to remove the door support rod from the door assembly.

7.Remove the case top and door assembly, then reinstall the fuel cap.

8.With the 1/2” socket wrench and exten- sion, remove the fuel tank. (Four bolts hold the fuel tank.) With the 3/8” nut dri- ver, remove leads #226 and #5W from the fuel gauge. Label the leads for reassem- bly.

9.Perform the Field Capacitor and Field

Rectifier Bridge Removal Procedure.

10.Perform the Output Capacitor Bank Removal Procedure. (Ranger 300 DLX only.)

11.Perform the Brush Removal Procedure.

12.Cut the cable ties from the reactor to the range switch.

13.Remove the fiber insulator plate from the hole in the vertical baffle.

14.Remove the four stator leads C1, C2, C3, C4 connected to the S2 range switch. Use care; excessive force will break the terminals away from the rivets. (DLX only. “D” machines have only one lead.)

15.Remove all stator leads from connection points on the front panel. See the Wiring Diagram. Remove lead #6 from circuit breaker CB2. Note that it passes through the idler current sensor. Remove lead #3 from circuit breaker CB3. Note that it passes through the idler current sensor. Disconnect the in-line connector on leads #42 and #32 located between the stator and the 14-pin amphenol.

Disconnect lead #E from the common ground screw. Remove lead W1 (heavy stator lead) from the top left side of the negative (-) output rectifier assembly. Untape and disconnect W2 from lead R at the 1/2” bolted connection to separate the stator from the reactor. Disconnect heavy lead A1 from the bottom of the negative (-) output rectifier to the reactor.

16.Using the 3/8” nut driver, remove the four screws (2 on each side) holding the output rectifier assemblies to the base of the machine.

17.Using the 1/2” wrench, remove the four choke mounting bolts from the base of the machine. Push the choke forward, toward the front of the machine.

18.Ranger 300 DLX machines only: perform the Output Contactor Removal Procedure. This is required in order to remove the choke, step 20.

NOTE: If the front of the machine is loose, it may not be necessary to remove the output contactor. The choke may be able to slide past the contactor if the front of the machine can be pulled forward.

19.Using the 1/2” wrench, remove heavy lead W4 from the choke to the center of the positive (+) output rectifier. On Ranger 300 DLX machines, also remove heavy leads W5 and W6 from the choke to the S2 range switch. See the Wiring Diagram.

20.Slide the choke assembly out of the machine.

SVM148-B specifications

The Lincoln Electric SVM148-B is a state-of-the-art inverter-based power source designed for both professional welders and hobbyists. As a versatile machine, it excels in a variety of welding applications including MIG, TIG, and stick welding. This machine is particularly notable for its efficiency and portability, making it an ideal choice for on-site projects or workshops where space is limited.

One of the main features of the SVM148-B is its inverter technology. Unlike traditional transformer-based welders, inverter welders are typically lighter and more compact. This means that users can transport the machine more easily without sacrificing power or performance. The SVM148-B is capable of delivering a substantial amperage range, allowing for adjustments that suit various materials and thicknesses, from thin sheet metal to thicker plates.

The machine offers adjustable output levels, providing precise control over the welding process. This level of control is essential for achieving clean, strong welds and is especially useful when working with different materials. The SVM148-B is equipped with digital display features that provide real-time feedback on power settings and welding parameters, allowing welders to make quick adjustments as needed.

Another significant advantage of the SVM148-B is its duty cycle, which is designed to accommodate extended usage without overheating. A robust duty cycle means that professionals can rely on this machine for prolonged periods, making it a dependable choice for heavy-duty tasks.

The SVM148-B also includes advanced safety features such as overload protection, which ensures that the machine will shut down in the event of excessive current draw. This feature not only protects the equipment but also enhances user safety during operation.

Moreover, the machine is compatible with a wide variety of welding wires and electrodes, adding to its versatility. Whether you're working with stainless steel, aluminum, or mild steel, the SVM148-B can adapt seamlessly.

In conclusion, the Lincoln Electric SVM148-B combines advanced inverter technology with user-friendly features, making it an invaluable addition to any welding setup. Its portability, control options, robust duty cycle, and safety measures set it apart as a reliable and efficient welding solution for professionals and hobbyists alike. Whether for a small workshop or large industrial applications, the SVM148-B meets the demands of modern welding with efficiency and ease.
