GROUND TESTS

CAUTION

This machine is equipped with solid-state electronic components which can be damaged if subjected to a ground test or a megger test without observing special precautions as outlined here:

A.Prior to the ground test always turn the engine off and remove the two Printed Circuit boards mounted on the rear of the welder control panel. For access remove the welder roof and the metal enclosures over the PC boards. Remove one screw from the smaller board and two screws from the larger board and pull each board straight out from the connector block. There are no wires to disconnect.

B.Connect the following jumpers:

1.Welding generator frame to base.

2.Across D13 (#232 to #1)

3.Across D14 (#234 to #75).

C.Place jumpers across the following points, see wiring diagram.

1.Across the voltmeter terminals if the unit is so equipped.

2.Positive side of SCR bridge (#75) to #214 on the SCR bridge located on the rear panel of the control box.

3.Positive side of SCR bridge (#75) to #212 on the SCR bridge.

4.Across C5 on the SCR bridge.

5.Negative side of the SCR bridge (brown generator field lead) to #214 on the SCR bridge.

6.Negative side of the SCR bridge to #212 on the SCR bridge.

7.Across C6 on the SCR bridge.

8.#1 on the two diode aluminum finned heat sink to #212 on the SCR bridge.

9.#1 on the two diode aluminum finned heat sink to #213 on the SCR bridge.

10.#2 on the base of D4, single diode mount- ed on copper heat sink to #75 on SCR bridge.

11.Across each of the three-phase bridge diodes, jumper from the heat sink across the diode on all six diodes.

NOTE: All jumpers must be as short as possible

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.
