BREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the gasoline engine on the WELDANPOWER 125, break-in is about 50 running hours.

Check the oil frequently during break-in. Change the oil after the first 5 hours of operation. For more details, see the Maintenance section of this manual.

LOW OIL SENSING

This engine has a built-in sensor that responds to low oil level (not pressure). When activated, the “Oil Gard” system will shut the engine down. The engine will not restart until sufficient oil is added. Check oil level fre- quently and add oil as required to the full mark on the dipstick. DO NOT OVERFILL.

CAUTION

During break-in, subject the WELDANPOWER 125 to only moderate loads. Avoid long periods running at idle. Before stopping the engine, remove all loads and allow the engine to cool several minutes.

Do not breathe welding fumes or gases.

Use ventilation or exhaust to remove weld- ing fumes from the breathing area.

Keep flammable material away.

Wear eye, ear, and body protection.

Moving parts can injure.

Do not operate this equipment with any of its doors open or guards off.

Stop the engine before servicing it.

Keep away from moving parts.

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

The WELDANPOWER 125 generator/welder can deliv- er from 50 to 125 amps of continuous welding output current. Output can be adjusted by setting the current control dial on the output control panel.

You can get maximum welding output by setting the dial to 125 AMPS. At high current settings like this, some output may decrease as the machine is used. If you are welding for a long time, you may need to turn the dial slightly upward to maintain the same results.

The numbers on the dial correspond to the average amps needed to weld using specific Lincoln welding rods. Table B.2, ELECTRODE SELECTION GUIDE, gives you the recommended dial settings based on the thickness of the work and the size and type of rod you’re using.
