5.WELDING TERMINALS SWITCH (DLX Model Only) The toggle switch labeled “WELDING TERMINALS ALWAYS ON” and “WELDING TERMINALS REMOTELY CONTROLLED” is used to control the operation of the RANGER 300 DLX output contac- tor. With the switch in the “WELDING TERMINALS ALWAYS ON” position, the contactor is closed at low and high idle.

When a wire feeder or TIG Module control cable is attached to either the 6-pin or 14-pin amphenol connector and the Welding Terminals switch is in the “WELDING TERMINALS REMOTELY CON- TROLLED” position, the contactor is open in low idle and high idle until and the wire feeder trigger or Amptrol is closed. This closes the 2-4 circuit. When the gun trigger or Amptrol is released, the contactor opens and there is no voltage present at the electrode (300 DLX only).

6.WIRE FEEDER POWER CIRCUIT BREAKER: Opens the wire feeder circuit and disables the feeder if a fault is detected in the circuit (300 DLX only).

7.15 AMP, 120 VOLT DUPLEX RECEPTACLES: Connection point for supplying 120 volt power to operate one or two electrical devices.

8.50 AMP, 120/240 VOLT RECEPTACLE: Connection point for supplying 240 volt power to operate one electrical device.

9.WELD OUTPUT TERMINAL (TO WORK) WITH FLANGE NUT: Provides the connection point for the work cable.

10.WELD OUTPUT TERMINAL (TO ELECTRODE HOLDER) WITH FLANGE NUT: Provides the con- nection point for the electrode holder.

11.GROUND STUD: Provides a connection point for connecting the machine case to earth ground for the safest grounding procedure.

12.6-PIN AMPHENOL: For attaching optional remote control equipment to the RANGER 300 D/DLX (Includes contactor closure circuit on the Ranger 300 DLX and remote control circuit).

13.14-PIN AMPHENOL (DLX Model Only): For attaching wire feeder control cables to the RANGER 300 DLX (Includes contractor closure circuit, remote control circuit, wire feeder 115/42 volt power source).

14.VOLTMETER (DLX MODEL ONLY): Displays actu- al voltage at the output terminals when welding in CV-mode.

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.
