WELDING CABLE CONNECTIONS

CABLE SIZE AND LENGTH

Be sure to use welding cables that are large enough. The correct size and length becomes especially impor- tant when you are welding at a distance from the welder.

Table A.1 lists recommended cable sizes and lengths for rated current and duty cycle. Length refers to the distance from the welder to the work and back to the welder. Cable diameters are increased for long cable lengths to reduce voltage drops.

Lincoln Electric offers a welding accessory kit with the properly specified welding cables. See the Accessories section of this manual for more information.

TABLE A.1

CAUTION

•Loose connections will cause the output terminals to overheat. The terminals may eventually melt.

•Do not cross the welding cables at the output termi- nal connection. Keep the cables isolated and sepa- rate from one another.

AUXILIARY POWER RECEPTACLES, PLUGS, AND HAND-HELD EQUIPMENT

The control panel of the RANGER 300 features three auxiliary power receptacles. See Figure A.1.

•Two 15 amp, 120 volt duplex (double outlet) recep- tacles.

Through these receptacles the machine can supply up to 12,000 rated continuous watts of single-phase, 60 Hz AC power.

For further protection against electric shock, any elec- trical equipment connected to the generator recepta- cles must use a three-blade, grounded type plug or an Underwriter’s Laboratories (UL) approved double insu- lation system with a two-blade plug. Lincoln offers an accessory plug kit that has the right type of plugs. See the Accessories section of this manual for more infor- mation.

CABLE INSTALLATION

Install the welding cables to your RANGER 300 as fol- lows. See Figure A.1 for location of parts.

1.The diesel engine must be OFF to install welding cables.

2.Remove the flanged nuts from the weld output ter- minals.

3.Connect the electrode holder and work cables to the weld output terminals. The terminals are iden- tified on the case front.

4.Tighten the flanged nuts securely.

5.Be certain that the metal piece you are welding (the “work”) is properly connected to the work clamp and cable.

6.Check and tighten the connections periodically.

If you need ground fault protection for hand-held equipment, refer to the K896-1 GFCI Receptacle kit in the Accessories section of this manual for more infor- mation.

CIRCUIT BREAKERS

The RANGER 300 machines are equipped with 50 amp circuit breakers on the 120/240 V receptacle and 15 amp circuit breakers on the 120 V receptacles for overload protection. Under high heat a breaker may tend to trip at lower loads than it would normally.

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.
