Prepare to troubleshoot internal components
Dirty, oily air is the root cause of many common problems that occur in Powermax
In some conditions it can void the warranty on the plasma power supply and torch.
The plasma power supply's built-in air filter can remove particulates as small as 5 microns. It can also
remove some moisture from the gas supply.
Before you begin:
■ Comply with the gas quality recommendations in
207.
■ If you work in an environment that is extremely warm and humid, or if work site conditions let oil, vapor,
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.
DIRTY, OILY AIR CAN CAUSE DAMAGE TO THE AIR FILTER BOWL
Some air compressors use synthetic lubricants that contain esters. Esters can cause damage to the
polycarbonates in the air filter bowl.
Add more gas filtration if necessary.
1. Examine the air filter element in the plasma power supply's built-in air filter.
2. Replace the filter element if it is dirty.
3. Clean the air filter bowl to remove oil, dirt, and other contaminants.
A yellow residue on the filter bowl shows that oil is getting into the gas supply line.
4. Replace the O-ring at the top of the air filter bowl if it has cracks or other damage.
5. If you use an external air filtration system, clean or replace any parts in it that are possibly dirty.
