CONNECTION OF THE K488 SG CONTROL MODULE AND K487 MAGNUM SPOOL GUN TO THE RANGER 300 (DLX ONLY) (SEE FIGURE C.6.)

1.Shut the welder off.

2.Connect the electrode cable from the SG Control Module to the ELECTRODE terminal of the welder. Connect the work cable to the WORK terminal of the welder.

NOTE: Welding cable must be sized for current and duty cycle of application.

NOTE: Figure C.6 shows the electrode connected for positive polarity. Use the Polarity switch on the Ranger 300 DLX to select the desired electrode polarity.

3.Connect the K691-10 Input Cable as shown in Figure C.6.

4.Set the slide switch on the SG Control Module to the “Lincoln” position.

CAUTION

Be sure the switch is set to the “Lincoln” (contact clo- sure) position before attempting to operate the SG Control Module. Incorrect switch position could result in damage to the SG Control Module and/or the Ranger 300 DLX.

5. Place the IDLER switch in the “HIGH” position.

CAUTION

Any increase of the high idle engine RPM by changing the governor setting or overriding the throttle linkage will cause an increase in the AC auxiliary voltage. If this voltage goes over 140 volts, wire feeder control circuits may be damaged. The engine governor set- ting is preset at the factory - do not adjust above RPM specifications listed in this manual.

6.Set the LOCAL/REMOTE switch to “REMOTE” if a K857 remote control is used. Set the switch to “LOCAL” if no remote control is used.

7.Set the OUTPUT RANGE switch to “WIRE WELD- ING CV.”

8.Set the WELDING TERMINALS switch to “WELD-

ING TERMINALS REMOTELY CONTROLLED.”

9.Adjust wire feed speed at the SG Control Module.

NOTE: For remote control, a K857 remote control is required. Connect it to the 6-pin amphenol.

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.
