WARNING

ELECTRIC SHOCK can kill.

●Do not touch electrically live parts such as output terminals or inter- nal wiring

ENGINE EXHAUST can kill.

● Use in open, well ventilated areas or vent exhaust outside

MOVING PARTS can injure.

●Do not operate with doors open or guards off

● Stop engine before servicing

●Keep away from moving parts

●Remove guards only when necessary and replace when work requiring removal is com- plete.

●Only qualified personnel should install, use, or service this equipment.

ROUTINE MAINTENANCE

At the end of each day’s welding, refill the fuel tank to minimize moisture condensation in the tank. Also, run- ning out of fuel tends to draw dirt into the fuel system. Check the crankcase oil level.

If the fuel supply runs out while the fuel pump is oper- ating, air may be entrapped in the fuel distribution sys- tem. If this happens, bleeding of the fuel system may be necessary. See the engine instruction manual.

AIR FILTER

SAM650 only:

The air filter element is a dry cartridge type. It can be cleaned and re-used; however, damaged elements should not be washed or re-used. Remove loose dirt from element with compressed air or water hose direct- ed from inside out. Compressed Air: 100 psi maximum. The filter should never be removed while the engine is running.

SAM400 only:

Inspect the oil bath air filter daily - more often in dusty conditions. When necessary clean and fill the oil bath. The filter should never be removed while the engine is running.

PERIODIC MAINTENANCE

1.Blow out the welder and controls with an air hose at least once every two months. In particularly dirty locations, this cleaning may be necessary once a week. Use low pressure air to avoid driving dirt into the insulation.

2.The SAM400 current control reactor brushes are self-lubricating and should not be greased. Keep the contacts clean. This control should be moved from maximum to minimum daily to prevent the controls from sticking.

3.See the engine Instruction Manual for periodic engine maintenance information. Change the crankcase oil at regular intervals using the proper grade of oil as recommended in the engine operat- ing manual. Change the oil filter in accordance with the instructions in the engine operating manual. When the filter is changed add one quart of oil to the crankcase to replace the oil held in the filter dur- ing operation.

4.Belts tend to loosen after the first 30 or 40 hours of operation. Check the cooling fan belt and tighten if necessary. DO NOT OVER TIGHTEN.

BEARING MAINTENANCE

This welder is equipped with a double-shielded ball bearing having sufficient grease to last indefinitely under normal service. Where the welder is used con- stantly or in excessively dirty locations, it may be nec- essary to add one-half ounce of grease per year. A pad of grease one inch wide, one inch long and one inch high weighs approximately one-half ounce. Over greasing is far worse than insufficient greasing.

When greasing the bearings, keep all dirt out of the area. Wipe the fittings completely clean and use clean equipment. More bearing failures are caused by dirt introduced during greasing than from insufficient grease.

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.
