OPERATING PRECAUTIONS

WARNING

Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists.

PIPE THAWING

WARNING

PIPE THAWING can result in fire or explosion.

● Only connect welder across

FROZEN section of CONTINUOUS METAL PIPE.

● While thawing, remove any ground leads con- nected to Frozen pipe.

●Turn welder on AFTER cables are connected to pipe. Turn off when done.

IMPORTANT: DO NOT USE A WELDER TO THAW A PIPE BEFORE REVIEWING LINCOLN BULLETIN E695.1 (dated May 1987 or later). This bulletin may be obtained from your local Lincoln distributor or by writ- ing directly to Lincoln Electric at the address on the back of this manual.

ADDITIONAL SAFETY PRECAUTIONS

Always operate the welder with the hinged doors closed as these provide maximum protection from moving parts and insure proper cooling air flow.

Read carefully the Safety Precautions page in the Instruction Manual before operating this machine. Always follow these and any other safety procedures included in this manual and in the engine instruction manual.

ENGINE CONTROLS:

FUNCTION/OPERATION

IGNITION SWITCH

When placed in the “ON” position, this switch energizes the fuel solenoid. When placed in the “OFF” position, the flow of fuel to the injection pump is stopped to shut down the engine.

SPEED CONTROL LEVER

Manually allows the engine to run at its high idle speed controlled by the governor or at the factory set low idle speed. When welding or using auxiliary power the speed control lever must be in the “RUN” position. To reduce the engine to low idle speed when not welding or not using auxiliary power place the speed control lever in the “IDLE” position notch.

ENGINE TEMPERATURE GAUGE

Displays the coolant temperature in the engine block.

OIL PRESSURE GAUGE

Displays the oil pressure to the engine. When the engine starts running, watch for the oil pressure to build up. If no pressure shows within 30 seconds, stop the engine and consult the engine instruction manual.

BATTERY CHARGING AMMETER

Displays the current going from the charging alternator into the batteries. It is normal for charging current to be high (above 15 amps) after starting or when the batter- ies are ‘low’ on charge.

ENGINE HOUR METER (Factory Installed Optional Feature)

The optional engine hour meter records the total run- ning time on the engine in hours. It can be used to keep a record of maintenance on the engine and or welder.

ENGINE PROTECTION SYSTEM

The engine protection system shuts down the engine under high coolant temperature or low oil pressure conditions by allowing the fuel solenoid valve to close.

SAM650, SAM400 specifications

Lincoln Electric has long been synonymous with welding excellence, and its SAM series of advanced welding machines, including the SAM400 and SAM650, epitomizes this commitment to quality and innovation. These models are designed to meet the demands of diverse industrial applications while ensuring ease of use, efficiency, and precision.

The SAM400 is a robust multiprocess welding system that supports MIG, TIG, Stick, and Flux-Cored welding techniques. It features a powerful 400 Amp output, suitable for heavy-duty applications and capable of handling materials such as steel, stainless steel, and aluminum. The machine incorporates advanced inverter technology, resulting in a compact design that significantly reduces the weight while enhancing portability. Furthermore, the SAM400 includes intuitive digital controls, allowing operators to easily adjust settings for optimal performance. Its PAS (Power Adapter System) compatibility enables users to seamlessly integrate different power sources, greatly enhancing its versatility.

On the other hand, the SAM650 takes it a step further, boasting a maximum output of 650 Amps. This model is particularly favored in industries requiring high deposition rates, such as shipbuilding and heavy fabrication. Like the SAM400, the SAM650 features multiprocess capabilities but adds enhanced control mechanisms, such as advanced waveform technology, which allows for better arc stability and reduced spatter. This ensures cleaner welds and, ultimately, a superior finish. Additionally, the SAM650 is equipped with Lincoln Electric's proprietary welding technology, including the Arc Control and Hot Start features that enhance user experience by providing smoother starts and consistent performance, even in challenging conditions.

Both machines come with integrated wire feeders that allow for easy adjustments and quick material changes, offering increased productivity on the job site. Their rugged design and durable construction ensure long-lasting performance, even in the harshest environments.

In conclusion, the Lincoln Electric SAM400 and SAM650 welding systems are trailblazers in the field of welding technology. With their powerful output, advanced features, and user-friendly interfaces, these machines cater to the needs of professionals looking for reliability and efficiency in their welding applications. Whether for small shops or large-scale industrial operations, the SAM400 and SAM650 deliver the performance and versatility that fabricators and welders depend on.
