Add additional gas filtration (if necessary)
It is extremely important to keep a clean, dry gas line to do the following:
Prevent oil, water, dirt, and other contaminants from causing damage to internal
components.
Get 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 conditions it can void the warranty on the
plasma power supply and on the torch. Refer to
the gas quality recommendations in the ratings
tables that start on page 24.
The plasma power supply contains a built-in air
filter. Regularly do a check of the filter element
inside the air filter bowl and replace as necessary.
Refer to Examine the air filter bowl and filter
element on page 171.
The built-in air filter must not take the place of sufficient 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 gets into 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.
The filtering system must be installed between the gas supply and the plasma power supply.
Additional gas filtration can make higher pressure from the gas supply
necessary. For the recommended gas inlet flow rate and pressure, refer to
Inlet gas pressure requirements (while gas is flowing) on page 58.
