Installation
& Operation
Compressed Air Testing/Setting Switch (8)
When positioned as ‘set’ compressed air control valve is open continuously.
This is useful for testing and setting the air pressure without having to activate the
trigger circuit. ‘Run’ posit-ion is normal operation.
Electrical Connection
The CUT series is designed to operate on a 3 phase 380-400-440V
AC power supply
.
Operating with a lower current rated supply circuit will reduce the rated maximum
output and duty cycle performance.
Compressed Air Requirements
A reliable and consistent supply of clean dry compressed air is essential for proper
operation. Although the machine contains its own internal air supply filtration
system it is recommended the compressed air supply should have external filtration
in the line feeding the machine, both a standard water trap (sintered bronze filter)
and also a coalescing filter (for oil in air).The air requirement is a minimum of
140 l/min Free Air Delivery (FAD) at 75psi pressure. This normally means the
compressor must be a belt drive model or if a direct drive it must have a motor
power of 2.5HP or greater. The air must be dry and free of oil and moisture
(normally a symptom of older, worn out compressors). The air hose must also be of
sufficient size (3/8”/10mm minimum) to supply the machine.
Basic Operation
1 Connect the earth cable quick connector to the earth connection socket.
Connect the earth clamp to the work piece. Contact with the work piece must
be firm contact with clean, bare metal, with no corrosion, paint or scale at the
contact point.
2 Connect the plasma torch to the machine central connector ensuring the
collar is done up firmly.
3 Connect the machine to suitable mains power using the mains input power
lead. Switch the mains power switch to ‘on’ to power up the machine.
4 Connect the compressed air supply to the filter/ regulator inlet.
Check the air pressure. Trigger the air flow using the ‘set’ function,
check the air pressure again and adjust if necessary. Return the switch to
‘run’ position.
5 Select the output current using the current control knob.
You are now ready to plasma cut!
