Additional gas filtration
It is extremely important to maintain a clean, dry gas line in order to:
Prevent oil, water, dirt, and other contaminants from damaging internal components.
Achieve optimal cut quality and consumable life.
Dirty, oily air is the root cause of many common problems that occur in Powermax systems, and in
some instances it can void the warranty on the power supply and on the torch. See the gas quality
recommendations in the ratings table on page 21.
The power supply contains a
built-in air filter. Regularly check
the filter element inside the air
filter bowl and replace as
needed. See Replace the air filter
bowl and filter element on
page 155.
The built-in air filter should not
take the place of adequate
external filtration. If you work in an
environment that is extremely
warm and humid, or if work site
conditions introduce oil, vapors,
or other contaminants into the
gas line, install an external
filtration system that cleans the
gas supply before it enters the plasma power supply.
A 3-stage coalescing filtration system is recommended. A 3-stage filtering system works as follows
to clean contaminants from the gas supply.
Install the filtering system between the gas supply and the power supply.
Additional gas filtration may require higher pressure from the source.
