3.1 GENERAL

Never, under any circumstances, operate the power
source with the cover removed. In addition to the
safety hazard, improper cooling may cause dam-
age to internal components.
To prevent serious injury, never touch any torch
parts forward of the handle (nozzle, electrode, etc.)
unless the power switch is in the off position.
Wear proper protective gloves, clothing, safety
glasses, and helmet. A helmet with filter lens shade
No. 11-14 should provide adequate protection for
your eyes. Refer to the Safety Precautions in the
beginning of this manual for additional operating
precautions.
