Questions and answers
In my Cutmaster 38, compressed air flows from the plastic tube at the bottom of the internal filter under ALL conditions if air is connected.
Compressed air flows from the plastic tube at the bottom of the internal filter on a Thermal Dynamics CutMaster 38 due to excessive oil, moisture, or other contaminants in the air supply. The system requires clean, dry air for proper operation, and contaminants can cause double-arcing, rapid tip wear, or torch failure. The internal filter helps remove these impurities, and if excess moisture or contaminants accumulate, air may escape through the plastic tube as part of the filtration process.
