erodes with use and develops a

pit in the end of the electrode. As
this pit grows wider and deeper
the quality of the cut degrades

necessary.
AIR PRESSURE AND VOLUME
Air pressure, flow rate and air quality are critical to quality plasma
cutting and consumable life span (see Specifications).
The volume capacity of your compressor is important, if you have a small
compressor with the same CFM rating as the plasma cutter, then the
compressor will run continuously when you are plasma cutting.
A compressor with a CFM rating slightly higher than the plasma cutter
would be more appropriate. A compressor with 1.5 to 2 times the plasma
cutter's requirement is better if you are doing a lot of cutting or cutting thick
plate. The same air consumption, but slower cut speeds equal a longer cut
time.

AIR QUALITY

Good air quality is essential to quality plasma cutting and consumable
life span.
The air from a compressor must be dry and free of particulate matter.
Minimizing the moisture in the air supply is critical to quality plasma cuts
and longevity of consumable parts.
When moisture droplets enter the high temperatures in the torch's
plenum, as much as 19,832°F, they immediately break down into
oxygen and hydrogen, which alters the normal chemical content of air in
the torch. These elements change the plasma arc, which alters the
nozzle orifice's shape and causing the nozzle to wear away. This affects
the cut quality in terms of edge, dross formation, a square edge and
edge smoothness.
As a minimum, be sure to drain the receiver (tank) on the air
compressor daily. Most air plasma systems have an on-board
particulate filter and/or a coalescing filter with an auto drain that will
remove some moisture from the air supply.
