Environmental Rating

The Precision TIG 225 power source carries an IP21S environmental rating. It may be used in normal indus- trial and commercial environments. Avoid using it in environments which have falling water such as rain.

Read and follow "Electric Shock Warnings" in the Safety section if welding must be performed under electrically hazardous conditions such as welding in wet areas or on or in the workpiece.

•The Precision TIG 225 must be located where there is free circulation of clean air such that air move- ment in and out the back air vents will not be restricted.

•Dirt and dust that can be drawn into the Precision TIG 225 should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.

GRINDING

Do not direct grinding particles towards the welder. An abundance of conductive material can cause mainte- nance problems.

STACKING
