PRODUCT DESCRIPTION

The SAM engine welders are multi-purpose welding machines. They are designed to be used on all open arc or submerged arc processes within the rating of the unit.

The machine is designed to be used with the following automatic equipment: LN-7, LN-8, LN-9, LN-22, LN- 23P (with Adapter Kit), LN-25, NA-3, LT-7, or LT-56. It can be used with most other equipment whose power requirements do not exceed the rating of the machine.

The SAM machines have two types of output charac- teristics; a variable voltage output characteristic for stick and submerged arc welding and also constant voltage characteristics for Innershield® plus both dip- transfer and spray-transfer processes.

INSTALLATION PRECAUTIONS

SPARK ARRESTER

Some federal, state or local laws may require that diesel engines be equipped with exhaust spark arresters when they are operated in certain locations where unarrested sparks may present a fire hazard. The standard mufflers included with these welders do not qualify as spark arresters. When required by local regulations suitable spark arresters must be installed and properly maintained.

CAUTION

An incorrect arrester may lead to damage of the engine or its performance. Contact the engine manufacturer for specific recommendations.

MACHINE GROUNDING

The 1984 National Electrical Code does not require this machine to be grounded under normal operating circumstances.

Some state, local or other codes or unusual operating circumstances may require the machine frame to be grounded. It is recommended that you determine the extent to which such requirements may apply to your particular situation and follow them explicitly. A

machine grounding stud marked with the symbol is provided on the welding generator frame foot.

In general, if the machine is to be grounded it should be connected with a #8 or larger copper wire to a solid

earth ground such as a metal water pipe going into the ground for at least ten feet and having no insulated joints, or to the metal framework of a building which has been effectively grounded. The National Electrical Code lists a number of alternate means of grounding electrical equipment.

WARNING

ADDITIONAL SAFETY PRECAUTIONS FALLING EQUIPMENT can cause injury.

● Do not lift this machine using lift bale if it is equipped with a heavy accessory such as trailer or gas cylinder.

●Lift only with equipment of adequate lifting capacity.

●Be sure machine is stable when lifting.

The recommended undercarriage for use with this equipment for in-plant and yard towing by a vehicle is Lincoln’s K767-1. If the user adapts a non-Lincoln undercarriage, he must assume responsibility that the method of attachment and usage does not result in a safety hazard nor damage the welding equipment. Some of the factors to be considered are as follows:

1.Design capacity of undercarriage vs. weight of Lincoln equipment and likely additional attach- ments.

2.Proper support of, and attachment to, the base of the welding equipment so there will be no undue stress to the framework.

3.Proper placement of the equipment on the under- carriage to insure stability side to side and front to back when being moved and when standing by itself while being operated or serviced.

4.Typical conditions of use, i.e., travel speed; rough- ness of surface on which the undercarriage will be operated; environmental conditions; likely mainte- nance.

5.Conformance with federal, state and local laws.(1)

(1)Consult applicable federal, state and local laws regarding specific requirements for use on public highways.

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.
