EMP-unit power side maintenance
NOTE!
There are no user-serviceable parts on the power-side. In dusty environments, the
power-side should be checked periodically for any dust/debris accumulation because
of the fan forced-air cooling used on this side.
Because of the electro-static sensitive components and exposed circuit boards any
maintenance on this side should be done by an authorized ESAB service technician.
