voltage protection inside the welder, the alarm light will on, at the same time, the current output will
be cut off.
If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the
welder life-span. The below measures can be used:
•
Change the power supply input net. Such as, connect the welder with the stable power supply
voltage of distributor;
•
Induce the machines using power supply in the same time;
•
Set the voltage stabilization device in the front of power cable input.
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 120 l/min (4.5cfm) 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.
