Torch System Error Indicator
Lights when issue with torch system or air supply detected and cutting output is disabled as a
result. Flashing light means that torch shield cap is not installed. Continuous light means likely
damaged or missing torch consumables or insufficient air pressure supply to the torch.
Alarm Indicator
Lights when over voltage,over current or electrical overheating (due to exceeding duty cycle) is
detected and protection is activated. When protection is activated, welding output will be disabled
until the safety system senses the overload has reduced sufficiently and indicator lamp goes out.
May also trigger if machine experiences an internal power circuit failure.
Air Regulator Pressure Adjustment
Correct air pressure is critical for plasma cutting. Incorrect air pressure will cause poor cut quality,
lack of cutting power, damage to the plasma torch and consumables and potentially damage the
power source. Optimum air pressure is between 0.45 and0.5MPa (65-75psi). Air pressure should
be set with the air flowing through the torch, as the pressure with the air flowing will normally be
less than static pressure, due to flow losses through the torch system. To unlock the pressure
regulator knob in order to adjust it, pull the knob upwards. Once the pressure is set correctly, push
the knob down again to lock it into place.
Air Filter/ WaterSeparator
As with correct air pressure, clean, dry air is also critical for plasma cutting machine performance
and reliability. The AdvanceCut series of Air Plasma Cutting machines are supplied with an air
filtration/moisture separator to assist with providing suitable air supply. The moisture separator is
self-draining, the water drain tube exits out the bottom of the clear condensate bowl. It is normal to
see moisture coming from this tube periodically. If excessive amounts of water or oil arebeing
produced in the condensate bowl and drain line, the compressed air supply should be checked for issues.
Pilot Arc System
The AdvanceCut series of Air Plasma Cutting machines use a pilot arc system to establish the main
cutting arc. A pilot arc system is a circuit where the return is back through the torch head and cable.
This means it can create a small arc with some cutting power without making any electrical connection
with the main machine earth. This is especially useful for starting cuts on material that does not
have a good initial earth connection, such as paint, rust, scale.
