HIGH FREQUENCY GENERATORS FOR TIG APPLICATIONS

The K799 Hi-Freq Unit and the K930-1 or -2 TIG Module can be used with the Ranger 300. The machine is equipped with the required RF bypass cir- cuitry for the connection of high frequency generating equipment. The high frequency bypass network sup- plied with the K799 Hi-Freq Unit does NOT need to be installed into the Ranger 300.

The Ranger 300 and any high frequency generating equipment must be properly grounded. See the K799 Hi-Freq Unit and the K930-1 TIG Module operating manuals for complete instructions on installation, operation, and maintenance. Also see the Acces- sories section of this manual.

REMOTE CONTROL

The Ranger 300 DLX is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connect- ing the K857 or K857-1 Remote Control (optional) or the K870 hand Amptrol or K812 foot Amptrol (TIG applications).

The 14-pin connector is used to connect a wire feeder or K930-1 TIG Module control cable. When a remote output control is used, the output control toggle switch must be set at REMOTE.

NOTE: When using the 14-pin connector, do NOT connect anything to the 6-pin connector if the wire feeder has a built-in power source output control.

Also see the Accessories section of this manual for more information on wire feeder connections.

WELDING TERMINALS

The Ranger 300 DLX has a toggle switch for selecting “hot” welding terminals (WELDING TERMINALS ALWAYS ON position) or “cold” welding terminals

(WELDING TERMINALS REMOTELY CONTROLLED position).

MACHINE GROUNDING

Because the RANGER 300 creates its own power from its diesel-engine driven generator, and if the machine is not connected to premises wiring (home, shop, etc.), you do not need to connect the machine frame to an earth ground. However, for best protection against electrical shock, connect a heavy gauge wire (#8 AWG or larger) from the ground stud located on the bottom of the output panel (Figure A.1) to a suitable earth ground such as a metal pipe driven into the ground. The ground stud is marked with the ground symbol.

WARNING

Do not ground the machine to a pipe that carries explosive or combustible material.

When the Ranger 300 is mounted on a truck or a trail- er, the machine generator ground stud MUST be securely connected to the metal frame of the vehicle. See Figure A.1.

If the RANGER 300 is connected to premises wiring such as a home or shop, it must be properly connect- ed to the system earth ground.

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.
