LOCATION
Locate the welder in a dry location where there is free circulation of clean air into the louvers in the back and out the front. A location that minimizes the amount of smoke and dirt drawn into the rear louvers reduces the chance of dirt accumulation that can block air pas- sages and cause overheating.
1.Before starting the installation, check with the local power company if there is any question about whether your power supply is adequate for the volt- age, 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 two or three phase line.
2.Models that have multiple input voltages specified on the nameplate (e.g., 208/230) are shipped con- nected for the higher voltage. If the welder is to be operated on lower voltage, it must be reconnected according to the instructions on the inside of the removable panel near the top left side of the rear panel. These instructions are repeated below:
