Air Supply - GYS PLASMA CUTTER 85A Manual Del Usuario

CONNECTION ON A GENERATOR
These machine can only work with generators as long as the 400V auxiliary power can supply the required amount of energy. The generator must
satisfy the following requirements :
- The peak alternative voltage is inferior to 700V.
- The fequency is comprised between 50 and 60 Hz.
- The effective alternative voltage is always superior to 400Vac ±15%.
It is imperative to check these requirements as several generators generate high voltage peaks that can damage these machines.
USE WITH EXTENSION CABLES
All extension cables must have an adequate size and section, relative to the machine's voltage.
Use an extension that complies with national safety regulations.

AIR SUPPLY

The air supply can come from a compressor or high pressure bottles. A high pressure manometer must be used on any type of air supply and must be
able to transport the gas to the plasma cutter. These machines come with an integrated air filter (5μm), but an extra filtering system can be necessary
depending on the quality of the air supply (impurities filter in option, ref. 039728).
If the supplied air is of low quality, the cutting speed is reduced, the cutting quality deteriorates, the maximum cutting capacity
diminishes and the life cycle of the consumables is reduced.
For optimal performance, the compressed air must comply with the standard ISO8573-1, class 1.2.2. The maximum vapor pressure point must be - 40
°C. The maximum oil quantity (aerosol, liquid et vapor) must be 0.1 mg/m3.
The recommended entry pressure during air circulation is 5 to 9 bars with a minimum of 305 L/min.
MANUAL TORCH SETUP
The torches are cooled with ambient air and do not require any special cooling.
1 - CONSUMABLES LIFE CYCLE
The replacement frequency of the Plasma Cutter 85A TRI et 125A TRI's consumables depends on several factors:
• The metal thickness.
• The average cutting time
• The cutting mode (manual or automatic).
• The air quality (presence of oil, humidity or other contaminants).
• The metal piercing or the cut from the edge.
• The adequate distance between the torch and the part when cutting or gouging.
• The adequate piercing height.
• The chain link cutting.
In normal conditions :
- During manual cutting, the electrode wears out first.
- During automatic cutting, the shroud wears out first.
2 - CHOICE OF CONSOMMABLES
The manual torch uses «protected» consumables. It is thus possible to drag the tip of the troch on the metal.
