RANGER 300 D (K1522-1)

•One constant voltage wire-feed welding range - 80 to 200 amps.

The wire feed setting permits the Ranger 300D to be used with the LN-25 Wire Feeder and .035, .045 or

.068 NR®-211-MP Innershield electrodes. Limited MIG (GMAW) welding can also be done with .030 or

.035 L-50 and L-56 using blended Argon shielding gas. “Auto-Idle” functions when using an LN-25 with an internal contactor.

RECOMMENDED APPLICATIONS

WELDER

The RANGER 300 provides excellent constant current AC/DC welding output for stick (SMAW) welding and for TIG welding, and it offers constant voltage output for DC semiautomatic wire feed welding.

GENERATOR

The RANGER 300 gives AC generator output for medi- um use demands.

ADDITIONAL FEATURES

RANGER 300 DLX (K1522-2)

•Four constant voltage (CV) wire-feed welding ranges with fine control on each range for welding at 40 to 300 amps.

•Excellent arc characteristics with MIG (GMAW) and recommended Innershield electrodes (FCAW).

•Wire feeder amphenol receptacle (14-pin) for quick connection of control cable.

•Voltmeter for reading CV wire-feed welding arc volt- age.

•Built in contactor with front panel selection of “cold” or “hot” welding terminals.

•Aluminum TIG welding when used with K930-1 TIG Module. Output contactor control with Amptrol.

•Recommended wire feeders are the LN-25 with 42 Volt Remote Output Control Module or with internal contactor and all models of the LN-7.

LIMITATIONS

•The Ranger 300 is not recommended for any processes besides those that are normally per- formed using stick welding (SMAW), TIG welding (GTAW), MIG (GMAW) welding and Innershield® (FCAW) welding.

•The RANGER 300 D/DLX is not recommended for pipe thawing.

•During welding, generator power is limited and out- put voltages can drop. Therefore, DO NOT OPER-

ATE ANY SENSITIVE ELECTRICAL EQUIPMENT WHILE YOU ARE WELDING. See Table B.5 for permissible simultaneous welding and auxiliary power loads.

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.
