SAFETY PRECAUTIONS

ELECTRIC SHOCK CAN KILL.

WARNING

•Only qualified personnel should install

this machine.

•Turn the input power OFF at the dis- connect switch or fuse box before working on the equipment.

•Do not touch electrically hot parts.

•Always connect the IDEALARC SP-250 grounding terminal (located on the side of the Case Back Assembly) to a good electrical earth ground.

•Set the IDEALARC SP-250 Power switch to the OFF position when connecting power cord to input power.

____________________________________

1.Before starting the installation, check with the local power company to determine if there is any ques- tion about whether your power supply is adequate for the voltage, amperes, phase, and frequency specified on the welder nameplate. Also be sure the planned installation will meet the U.S. National Electrical Code and local code requirements. This welder may be operated from a single-phase line or from one phase of a three-phase line.

2.Models that have multiple input voltages specified on the nameplate (e.g., 208/230) are shipped con- nected for the highest voltage. If the welder is to be operated at a lower voltage, it must be recon- nected according to the instructions on the inside of the removable panel (Reconnect Access Door) near the top left side of the Case Back Assembly. Also see the Reconnect Section of this manual for details on reconnecting the machine to operate at different voltages.

3.Be sure the voltage, phase, and frequency of the input power is as specified on the machine rating plate. See Figure A.1 for the location of the machine’s input cord entry, Reconnect Access Door, Reconnect Panel, and Rear Nameplate.

SELECT PROPER LOCATION

Place the IDEALARC SP-250 where clean air can freely circulate in through the front intake and out through the rear louvers. Dirt, dust, or any foreign material that can be drawn into the machine should be kept at a minimum. Not following these precautions can result in the nuisance shutdown of the machine because of excessive operating temperatures.

STACKING

The IDEALARC SP-250 cannot be stacked.
